How to embed a lock into an interior door with your own hands. The height of the lock on the interior door. How to fit a lock into a door How to fit a lock into a door

Requires a minimum set of tools:

• Drill
• Chisel 19 mm
• Crown diameter 50 mm
• Spade drill 23mm wide
• Drill bit for wood or metal 4 mm
• Hammer
• crosshead screwdriver
• And a pencil

So, let's start cutting into the lock.

Drill a hole in the center with a 4mm drill bit.

We place the lock flush with the door and make a mark according to the fact

We drill through the hole with the same drill, maintaining a right angle.

Using a 50 mm crown we make a cut on one side of the door.

Attention!

Your specific case may require a different size crown.

Let's finish on the other side.

We take a self-tapping screw of a suitable length, close the door along the door frame and through the 50 mm hole, insert the self-tapping screw into the remaining 4 mm hole and, using pressure, make a mark in the door frame.

Using a 23mm feather drill, we cut a hole at the mark to a depth sufficient for the lock latch to engage.

Using the same drill, we drill a hole for the lock along the mark.

We insert the lock and make a mark with a sharp pencil to recess it into the door leaf.

Using a chisel, we make notches strictly according to the marks and make a selection so that the lock sits in the pocket, then we fasten it with self-tapping screws.

We begin to assemble the lock, insert the outer part into the grooves (as a rule, it does not require disassembly).

Then carefully remove the decorative “cup” sitting in the grooves, then press the latch and remove the handle.

We connect the two sides with screws.

We insert the handle so that the latch operates.

Snap the decorative “cup” into place.

We attach the striker, make a mark, use a chisel to remove the excess and screw it on.

Done!))) A correctly embedded lock closes freely by pressing the door leaf until it slams.

Video explanation for installing the lock

Instructions for installing a door lock (knob)

1.Marking the door

Apply markings on the door leaf to install the knob (lock) according to the template. Recommended distance from the floor is 965 mm.

2.Marking holes

After you have made the markings, drill two holes: 50 mm in diameter for the knob (lock) handle and 23 mm in diameter for the latch mechanism.

H. Installing the strike plate

Install the strike plate at the same height as the latch so that the additional tongue of the latch remains recessed into the body of the latch when closing, which is an obstacle when pressing.

4 Disassembling the knob (lock)

To disassemble the knob (lock), use a special key to press the spring-loaded latch at the place where the handle is attached and remove it.

5. Latch length adjustment

6. Installing the latch

Install the latch into the groove of the door (make sure that the bevel of the latch is directed towards closing the door). Install the cover plate with the rod so that the rod and coupling sleeves fit exactly into the grooves on the latch body.

7. Installing the knob trim(castle)

First, slide the inner jujube cover plate onto the rod and secure it with screws (or screws). Then screw on the outer part of the trim.

8. Handle installation

Install the handle so that the groove on the rod coincides with the groove on the knob handle, press the handle until it “clicks.”

9. Rearranging the mechanism in the halyard handle

For models of latches with a halyard handle (versions 01 and 03), installation is also provided for both left and right doors. To do this, it is necessary to remove the cylinder mechanism and the fixing mechanism from the handle body and swap them (according to the figure), in accordance with the side of the door opening.

Installation procedure.

1. Determine the installation location of the knob and apply markings, following the template and installation instructions.

2. Using the installed latch body, mark the installation location of the strike plate on the door jamb and select a groove for the strike plate.

3.Install the strike plate and secure it with screws.

4. Alternately check the operation of the knob from outside and inside the room.

5. For models of latches with a halyard handle (versions 01.03), installation on left and right doors is also provided. To do this, it is necessary to swap the locking mechanism and the cylinder mechanism from the handle body.

As you can see, fitting a lock into a door is not such a difficult task, the main thing is not to rush.

Very often, when changing doors between rooms, we are faced with the question - how to properly install a door handle with a lock? With the help of this article, you will be able to install a lock on your interior door quickly and, most importantly, correctly, avoiding the mistakes made by many inexperienced people. In fact, this is not a complicated process at all; it takes up to half an hour for an experienced master, but an inexperienced person in this matter can suffer for several hours.

In this article we will look at the installation of the most common lock design today. This lock consists of the following parts:

Lock Mortise Tools

To install an interior lock, you need a minimum set of tools; you most likely already have some of them, but if you have to buy something in addition, you will not incur large financial costs.

1. Tape measure and pencil;
2. Screwdriver or drill;
3. Stationery knife;
4. Chisels 10 and 20 mm;
5. Spade drill or 23mm forstner drill;
6. 2 mm drill;
7. Wood crown 54 or 50 mm depending on the thickness of the door;
8. Masking tape.

This is a list of the best tools you will need. Special kits for inserting locks are sold; they are relatively inexpensive, but it will be even cheaper to purchase everything separately. Often, such kits include a 22 mm feather drill; it is also suitable, but then you will have to widen the hole for the latch with a chisel.

Making holes for the handle of the lock mechanism

Like any installation process, the installation of a lock begins with markings. But before that, let’s protect the door leaf from accidental damage. To do this, we use masking tape to cover the end and plane of the door at the intended installation location of the lock, this is a distance of approximately 90 to 110 cm from the floor. Pasted masking tape will not only protect our door from damage, but also make markings on it much more convenient.

First of all, mark the height of the door handle with the lock. Most often, the handle is placed at a height of 1 m from the floor level. We measure this distance with a tape measure and put a mark on the plane of the door with a pencil.

When purchasing this type of lock, it always comes with a template for accurately marking the location of the holes. The cylinder mechanism of the lock may differ in diameter from different manufacturers, so purchase a wood crown after purchasing the lock. If your lock kit did not include a template, you can print them from this article as pictures and use them when installing the lock.

Gently bend the template along the line of the door ledge and attach it to the door from the end. Depending on the thickness of the door leaf, use a sharp object (a self-tapping screw or the tip of a feather drill) to mark the centers of the holes according to the template from the end and on the plane of the door.

Using a screwdriver and a wood bit, drill a hole in the plane of the door.

Advice: When drilling, be careful not to drill through the entire door at once. When, while drilling, the guide drill appears on the back side of the door, stop and start drilling with a crown on the other side, this way you will definitely avoid chips on the plane of the door leaf.

The next step is to drill a hole for the lock latch. Using a previously applied mark using a template on the end of the door, using a 23 mm feather drill, we drill a through hole to the previous one.

Keep the drill strictly perpendicular to the door, otherwise in the future the latch may become oblique and jam during operation.

The next step is to insert the latch into the end hole, align it with the edge of the door and trace it with a pencil along the contour of the decorative frame. After this, we take out the latch and, using a stationery knife, make an incision along the marked line in the top layer of the door leaf. And only then, using a chisel, we select the hole for the lock latch. The depth of the hole should be slightly less than the thickness of the latch frame; later, when you tighten the latch with self-tapping screws, it will be pressed into the wood and become flush with the plane of the door.

Advice: Many beginners immediately begin to cut under the latch with a chisel; this is incorrect, since the door leaf is covered with a film that can be damaged beyond the cut line with a chisel, so cut off the film first.

After selecting the groove, insert the latch into place and first, using a 2 mm drill, drill out the holes for the self-tapping screws and tighten the latch into place. If the latch fits into the hole tightly, then use a chisel to cut off the contact points between the latch and the hole.

Let's start installing the handle. The handle is assembled according to the instructions supplied with it. When installing, pay attention to the location of the closing tongue on the handle; if there is one, it should be located inside the room.

On one of the cylinder mechanisms there is a rotating pin and holders for mounting screws. Remove the decorative rosette from the mechanism using the pin wrench from the kit and mount it in place, screw the second cylinder mechanism on the reverse side.

When tightening the screws, do not overdo it - pinched cylinder mechanisms will not work as expected.

Install all parts of the handle in place according to the attached instructions, and the work on installing the handle is completed. In fact, this is done much easier than it seems; you can watch a video in which you will clearly see the entire process of installing the lock with your own hands.

Installation of the lock mate

The last step in installing a door lock on an interior door will be installing the counter part on the doorway.

Close the door and make two marks on the doorway based on the width of the lock latch.

Measure the distance from the corner of the door to the beginning of the latch.

You should have the same distance from the edge of the doorway to the beginning of the recess of the counter part. It is necessary to maintain this distance so that in the future the closed door does not move back and forth due to air movement in the apartment and does not knock.

If the answer needs to be recessed into the door jamb, then we place it in place and outline its outer and inner contours with a pencil. If there is no need to recess, then we outline only the inner contour. It all depends on the gap between the door and the jamb.

Using a drill of a suitable diameter (you can also use a feather drill, if the hole then does not protrude beyond the answer), drill a hole for the lock tongue and fasten the answer in place, having previously drilled 2 mm holes for the screws with a drill.

Do not forget to widen the holes for the screws to a depth of 2-3 mm, since there are protruding parts in this place on the back side of the answer.

We install the striker in place by tightening it with self-tapping screws and try to close the door; if there is excess play, we eliminate it by bending the tongue on the striker.

The insertion of the lock into the interior door has been completed, all that remains is to clean up the accumulated debris and enjoy the new handles on the doors.

Lock mortise with cylinder

Very often a situation arises when you need to install a lock on a door that already has a handle. Any lock with a cylinder is suitable for this.

Such locks have a rectangular shape and therefore the insertion process may seem difficult without the use of special tools. In fact, such locks are installed quite easily and with a minimum set of tools. You can place them at your discretion - above or below the already installed handle.

Lock installation sequence:

Installation of the lock mate:

• On the open door, we pull out the bolt (the retractable part of the lock) of the lock, that is, we close the lock with a key and, leaning it against the doorway, we mark what height we will have the counter part, focusing on the edges of the crossbars;
• Using a tape measure or square, measure the distance from the edge of the door to the middle of the lock and transfer this distance to the jamb of the doorway;
• Using a feather drill, we drill a series of holes according to the markings and then combine the resulting holes with a wood drill;
• Having previously secured the response part to the jamb, use a utility knife to cut along the contour, and then use a chisel to select the countersunk hole for the response;
• We install the counter part in place and check the functionality of the lock again.

Also, such locks often come with handles; the sequence of inserting such a lock does not change, only the operation of drilling a hole for the handle is added.

Well, that's it, the lock is cut in!

Be sure to watch the video on inserting a lock with a cylinder, perhaps in it you will notice some subtleties that you did not understand from the article.

If you have any questions, you can ask them in the comments. Good luck with the renovation!

If you decide to install interior doors with your own hands, it is worth noting that the easiest way is when the insertion of door locks and hinges is not done with your own hands, but at the manufacturer’s factory. As a rule, the manufacturer carefully selects such accessories, is reliable and has excellent performance characteristics. Read more about choosing door locks. When buying doors with installed fittings, however, you may encounter some difficulties in choosing. The most common thing is that the color or design is not suitable. For example, you want a gold-colored lock, but the manufacturer says chrome. Or you need Italian magnetic locks AGB, with silent closing like Morelli, with a plastic tongue, but they offer steel. Regarding hinges, you can get by with little expense - buy door hinges without a mortise. A universal loop without an insert does not look so aesthetically pleasing, but still.

There is always a way out - just buy what you need, cut in the locks/hinges with your own hands and install. It is not worth saving on fittings, since a failed mechanism can significantly complicate the further operation of interior doors. Exactly the same lock or door hinges may no longer be released, and an analogue, as a rule, will not “fit” into an already formed groove. We recommend embedding and installing silent or magnetic locks AGB, Morelli (Italy). For more than 10 years now, the installation dimensions of these products are the same and you can easily replace them as needed, although they simply do not break.

So the locks, universal or hidden hinges have been selected, purchased and brought, you need to install them yourself. For example, for unfamiliar fittings, we first draw a diagram of the upcoming insertion in the real size of the AvtoCAD program for automated installation, but you can mark it according to the manufacturer’s instructions, especially if the insertion of the lock and hinges is done by yourself. Marking is an important stage, it is necessary to pay special attention to it. “Measure twice, cut once” - it works! Otherwise, the product is damaged, the supplier will not exchange it for you, and this is a considerable financial loss. The marking directly depends on the type of lock and its features. It is important to dance from the hole under the handle. If you do not take this into account, then the door handles may end up at different distances from the bottom of the door leaf, and if the doors are installed in close proximity to each other, it will come out - oops or oops! When making calculations and markings, use a square, tape measure, pencil, awl or construction knife.

Do-it-yourself insertion of door hinge locks - methods

1. Using a drill and chisels - the old-fashioned method

The most common is what is called the “household” option.

Marking and inserting an interior lock

We take a tape measure and measure from the bottom of the canvas, at the end where the lock will cut in 95 cm (this is our standard, 100 cm is possible), apply a square, draw a transverse line and transfer the markings to the plane of the canvas, to mark under the door handle. Marking is done with a sharp pencil or awl.

We take the lock and use a square to measure the distance from the front plate to the middle of the square hole of the handle and apply the result on the plane of the canvas on both sides. We apply the lock to the end of the canvas, so that the line drawn in advance for the handle is in the center of the hole in the square and mark the upper and lower edges of the lock. We will drill this size. Next, use a square to mark the center of the canvas and draw the center line of the insert.

After marking for the lock and along the drawn center line, drillings are made on the end part of the canvas with a pen (usually 14-16 mm, depending on the thickness of the lock), as often as possible from each other. In order not to drill out too much, a notch is made on the feather drill to the depth of the lock using iso or masking tape.

The trick is to avoid catching the adjacent hole with the pen, since a drill rotating at high speed can suddenly jam, get stuck and damage the door. Then the groove is formed using several flat chisels, first removing excess wood along the blade, and then cleaning the side planes so as not to split the blade. Then holes are drilled for the handle, and, if necessary, for the cylinder (key) or screwdriver. It is important to drill holes on both sides of the canvas, and not through it! A lock is inserted into the formed groove, aligned with the drilled hole for the handle, its overhead, decorative strip is outlined with a sharpened pencil and the final selection is made with a chisel.

That's it, the lock mortise is done by hand!

Mortise of the lock mate

The counter part or “response” is cut in after the door block is installed. The markup is very simple. We close the door and, through the pretend gap, mark the lower and upper edges of the latch. We draw transverse lines on the box. Next, use a square to measure the distance to the edge of the tongue on the door and transfer it to the frame. This will be the limiter for the upcoming drilling and installation of the answer.

We drill two holes with a pen, and select the central part with a chisel. We attach the lock strike plate, drill holes for the screws and fasten it. We try - everything works. The answer should be deepened only if its thickness exceeds 1 mm. This is done with a chisel, having previously outlined the screwed-on mating part.

Marking and inserting door hinges

The trick is that marking and inserting hinges should begin with the door leaf. And so our door is 2000 mm, and the hinge is 200 mm, we measure 20 and 160 cm from the top of the leaf along the end, draw transverse lines, apply the loop parallel to the end of the leaf below the line and mark the edges with a sharp pencil.

It is more correct to mark exactly the loop that will subsequently be installed in this particular groove, since the factory stamping may differ. We take it with our own hands, and with the help of a chisel, and as shown in the video, we cut the lower and upper hinges into the door.

Another feature is the insertion depth. It happens that the gap between the parallel folded parts of the hinge is less than 2 mm, and the requirements for the hinge gap of the door block are just 2 mm. In this case, the loop needs to be deepened a little less. There may be a gap of more than 2 mm, then the loop still cuts flush with the plane of the end! Thus, you will have to come to terms with the hinge gap of the assembled block, but take this point into account when calculating, marking and filing the top element of the box, since it is standardly 6 mm, 4 mm from the rebate part and 2 mm from the hinge part, respectively.

The next stage is inserting the loops into the box element of the block. So the hinges are cut into and installed in the canvas, we attach the box and mark the edges of the hinges. We apply the loop to the marks parallel to the door frame and trace it with a pencil.

There is one correct nuance. We should take into account in advance the fact that the thickness of the door leaf and the width of the quarter frame from the seal to the edge may be different, but we really need a good rebate, that is, a tight (but not too tight!) fit of the seal to the leaf when the door is closed! To do this, before inserting the loops, we measure these values.

Let’s say the blade is 40 mm and the quarter is 42 mm, what should we do? Everything is very simple, you need to cut the loop into the box 2 mm deeper into the seal than into the canvas. But this is initially incorrect, since in this case, a deep-set hinge will expose part of the mortise, and when opening/closing the door, it will begin to wipe against the frame or platband, producing an unpleasant creak. Therefore, it is more correct not to recess the hinges in the box, but to push them out on the canvas and by the same 2 mm.

Flaws

• There is a high risk of damage to the door leaf coating as a result of a slip drill or chisel, especially if the tool is not sharpened to razor level before starting work! Sharpen cutting tools, use new drills,
• there is a great risk of simply splitting the canvas through inept actions or, say, stabbing, which will then significantly affect the strength and durability of door blocks and structures,
• you may not like the aesthetics of the inset, especially if you have no experience in “wood carving”,
• it will take a long time, but “long” is not something that should frighten a novice craftsman eager to cut into locks and hinges with his own hands,
• The list can be continued, but the lock in the interior door has already been installed with your own hands, and this is the main thing!

Advantages

• in skillful, diligent and diligent hands, there may not be all the shortcomings, do not be alarmed,
• the cheapness of the tools used, especially if you practice “household”. Do not buy frankly cheap chisels and feather drills!

2. Inserting hinges and locks into doors using a hand router.

The technology depends on the type of equipment used. There is a technology of template milling, when all manipulations are carried out according to a pre-prepared template or using a “ruler”, using cutters of different diameters and lengths. There is, of course, professional equipment, where everything is thought out and adapted for the work. In any case, the basic principle is rotating at a speed close to 25 thousand rpm. a milling cutter with the help of which the correct insertion of hinges and locks into an interior door occurs with your own hands. For example, in our work we use more than three types of milling cutters from the manufacturers Makita and Virutex, various templates and a Spanish template holder, screw and spiral cutters of different diameters from “CMT” Germany.

The markings for inserting with a router are no different from household ones, and the milling itself has a number of features, which will be discussed below.

As for the door lock, cutting it in with your own hands using a router is carried out using a standard ruler that comes with the equipment, using cutters of different diameters. In general - nothing complicated, the main thing is that the stroke of the collet with the cutter provides it with the necessary immersion depth, to the height of the lock, respectively. In the video, a do-it-yourself lock using a router is made offset to the left edge. This is another subtlety of installing silent AGB locks and more. The counter part of the lock with the tongue is rounded and should be installed along the edge of the box, so in order for the lock to look beautiful, you need to take this into account when inserting it, moving the lock along the canvas if necessary.

Do-it-yourself cutting of hinges with a router has a number of features. On the door leaf, everything is similar to the lock, using a ruler we select the plane, depth and parallel edge, then we form the end edge with a chisel of 30-40 mm.

The trick is that in order for the end edge to turn out beautiful and accurate, the chisel must be held perpendicular to the plane at the moment of hitting with a hammer, chopping and cleaning the wood in several stages, a little at a time, this is important.

It is more difficult to embed hinges into the door frame with your own hands, since, unlike the door leaf, which has one pressing plane, the frame consists of two planes. Essentially, you will have to mill the lower plane and press the equipment platform to the upper one. The task is not easy, and therefore our milling cutters have special modifications to the platform. Of course, there are all sorts of devices, carriages, templates and even a special loop router made by Virutex. We didn’t use carriages, you get tired of making templates for each loop, but loop Virutex is a thing, but it’s expensive, and we don’t need it. How can you cut hinges into a box with a simple router, but with your own hands - I don’t know, I’ve reached a dead end, ideas will come up, I’ll add to the article.

Flaws

• high cost of equipment,
• all sorts of nuances associated with inept use.

Advantages

• Precise, high-quality, neat insertion of locks and hinges into interior doors, made by yourself!

This article is a step-by-step instruction on how to embed a lock into interior doors with your own hands. Here, ZAMSERVICE specialists share their skills and experience, describe the installation process in detail, and also give personal recommendations regarding the choice of a locking system. By following their advice, you can easily install the lock yourself.

If you bought an interior door without a lock or the old mechanism has expired, then it’s time to familiarize yourself with the nuances of installing a new product. The ease of installation directly depends on the modification of the selected device. The easiest way to mount latch handles is by carefully cutting out a hole of the required diameter, while locks with cylinders, rotary latches and handles require a more complex installation process.

For what reasons may you need to mortise the lock yourself?

Interior doors are installed in every apartment or house. They competently divide space, serve as protection against unauthorized entry, drafts, extraneous noise, etc. The door leaves themselves are not complete without a reliable locking mechanism. Many door manufacturers do not provide them with built-in locks.

If you bought an interior door without a locking system, then you can install it yourself. The main thing is to approach this issue responsibly, not to rush, to act carefully and consistently.

Another reason to cut the lock into the door yourself is if the old device breaks down. This can happen due to the expiration of the operational life, due to improper use of the lock, ignoring preventive measures, as well as due to mechanical damage to the structure.

In some cases, inserting a lock with a cylinder allows you to avoid large-scale repairs in the future, since replacing the cylinder is much easier and cheaper than completely changing the locking structure. Replacing the core will also be appropriate in cases where keys are stuck in the keyhole, as well as if they are lost or stolen.

How to choose a lock for interior doors

Before you install a lock on your interior doors, you need to purchase one. The design should be chosen based on the parameters of the door leaf; in particular, it is worth taking measurements first. If the width of the vertical bar of the door is less than 4 cm, then mortizing the lock is not only a pointless exercise, but also practically impossible.

In this case, door latches are more suitable, as they are quite easy to install and are the easiest way to lock doors. In addition, the choice of such designs is more than diverse. The modern market offers products of various sizes, installation types, colors and designs.

If the doors have higher security requirements and their width exceeds 4 cm, then mortise locks for interior doors of any well-known brand will be suitable. They are available in a wide range, ranging from standard models to multifunctional designs complete with door handles. The appearance of the product also matters, so the locking mechanism, or rather its external parts, must be in harmony with the color and design of the door.

Correct markings – high-quality lock mortise

Installing any lock always starts with markings. It is very important to avoid mistakes at this stage, since incorrect measurements lead to incorrect formation of the seat, which will certainly affect the quality of installation work in the future. As a rule, the consequence of illiterate marking is a distortion of the structure. That is why the contours should be marked as accurately and carefully as possible.

Many manufacturers of high-quality fittings and locking and hardware products complete their products with special templates for marking. This greatly simplifies the process and guarantees the exact location of the lock on the door leaf. If such blanks are not provided in the package, then you will have to make the markings yourself by attaching the structure to the door and tracing its contours with a pencil or any other writing instrument (felt-tip pen, pen, marker, chalk, etc.)

Before you pick up the tools for drilling holes and forming seats, you need to double-check the correctness of the markings several times. This will ensure reliable operation of the mechanism and eliminate the formation of distortions.

Step-by-step instructions for installing a lock

So, a suitable design has been found and purchased at the store, so it’s time to start inserting the lock. To do this, you need to perform a number of sequential actions:

• Mark the location of the lock on the door (usually 1 meter from the floor).
• Drilling a hole for inserting a lock with a drill (the diameter of the pen drill must be equal to the thickness of the lock, and the depth of the drilled hole must match the length of the lock structure).
• Marking the outline of the base plate on the door leaf.
• Carefully drill a hole for the handle (the drill should go right through the door).
• Marking the hole for the screws (attaching the structure to the intended seat).
• Drilling a hole to attach the lock to the door leaf (according to the received markings).
• Installation of decorative overlays.
• Fixing the rod connecting the door handles.
• Closing the doors and marking the location of the tongue on the door jamb.
• Apply the receiving pad to the intended location and trace its outline using a simple pencil.
• Measuring the length of the lock tongue and transferring it to the door frame.
• Attaching the lining to the seat with self-tapping screws.
• Checking the functionality of the device (adjusting or reinstalling the tongue if necessary).

As a rule, the above instructions are suitable for all types of interior doors, including those made of particle board, natural wood and plastic (in this case, you need to buy special locks designed for PVC products).

Features of mortise locks for various types of doors

Before embedding the lock into the MDF door, it is necessary to accurately measure 1 meter from the floor, since it is at this height that the additional wooden beam is located, and the rest of the door is hollow. By ignoring this recommendation, you can ruin the door leaf, and hopelessly. If any difficulties arise with the installation process, it is better to immediately contact specialists. The locksmith will install the lock expertly, while the door will retain its presentability and functionality.

Metal doors for installation inside apartments and houses are very rarely used, however, if you have this particular type of door leaf, then it is more advisable to use the services of professionals. In addition to the fact that such doors require a special type of lock, the process itself is particularly complex.

Interior doors made of plastic are quite common in modern interiors. You can fit a lock into such doors with the same ease as into wooden ones. The only thing is that the locking device itself must be designed for use in PVC products. Otherwise, the advice of specialists on installing locking systems in interior units is almost identical to the instructions above.

What tools are needed to mortise a lock?

You can install a lock on interior doors using simple tools that every home craftsman has. You will need:

• Hand drill with feather drills
• Chisel.
• Screwdriver.
• Screwdrivers (phillips and flathead).
• Carpenter's square.
• Hammer.
• Roulette (ruler).
• Pencil (pen, thin marker, felt-tip pen, chalk).

So, we figured out what tools are needed to install standard locks on interior doors. This list may vary depending on the complexity of the work, the type of door or mechanism. Some devices can be replaced with analogues. For example, instead of a chisel, you can use a chisel, and self-tapping screws can be easily screwed in using a drill.

And yet, not all types of locks can be cut using available tools. In some cases, you may need a milling cutter - a special device for door blocks that ensures high accuracy of the landing recesses. The milling machine is quite compact and easy to use. Using it, you can cut a groove of any shape and size, give the edges of the workpiece the correct shape, prepare niches for hinges and seats for locking mechanisms.

Mortising a lock with a router

If you have a milling machine at your disposal, then the task of installing a lock on interior doors becomes much easier. The lock is inserted with a router in a vertical position of the door on its side, which is achieved by securing it with a slipway. This avoids the need to constantly support the blade with your hands.

Having fixed the position of the doors, we proceed to mortise the lock:

• We mark the seat of the lock body and tongue.
• We cut out a recess for the locking device using a hand router.
• We insert into the machine a cutter corresponding to the dimensions of the plank.
• Adjust the required depth.
• We make a recess in the center.
• We prepare the seat for the body.
• We straighten its edges using a chisel.
• We insert the lock according to the above instructions.

A router is not a necessary tool for installing locking mechanisms, but some types of locks are almost impossible to install without it. This applies to latched locks, for the installation of which it is necessary to prepare a neat hole for the keyhole. Mortizing a lock without a cutter in the case of standard devices for interior doors is quite possible if you have all the necessary tools at hand.

In addition to step-by-step instructions for inserting locks into interior doors, each master has his own secrets that allow him to complete the installation as efficiently and quickly as possible:

• In order not to cut off extra millimeters with a router, the contours of the external markings can be limited with masking tape.
• Drilling through doors can damage the door leaf, so you can divide this stage into two steps. First you need to drill the door on one side, continuing drilling until the point of the drill appears on the back side. Then perform similar actions on the other side of the doors, using the resulting hole as the center.
• To hide the lock well in the hole, its depth should be 2-3 mm greater than the width of the lock body.
• If the lock is installed correctly, the door will unlock/lock without jamming or unnecessary effort. Otherwise, it is necessary to change the location of the counter plate.
• If you do not have suitable tools for installing locks, but you are going to buy them, then pay attention to special kits for inserting locking mechanisms. These kits include drills and bits that are exactly the right size.
• Immediately before attaching the lock to the door with self-tapping screws, it is recommended to verify its functionality. Try repeating several cycles of unlocking/locking the lock with the key and make sure that the mechanism is working properly.

Marking the position of the lock on the interior door

The distance from the floor to the door handle will be approximately a meter. A lock is applied to the door from the outside and the place where the lock mechanism will be installed is marked - there will be corresponding groove . Along its boundaries, mark with a pencil 2 horizontal lines and one axial line between horizontal. Also mark the width of the groove. This value is equal to the thickness of the locking mechanism.

The next stage is selecting a hole for the lock.

After this, we remove the screws, then the lock and use a chisel to select the canvas along this mark to the depth of the plank. At the same time, try on the lock, keeping an eye on the position of the level of the bar relative to the canvas - it should not go deep into the canvas, but it should not stick out either.

Then you need to insert the lock into the door and secure the front plate with self-tapping screws. Then install the handles and clamps and secure them with self-tapping screws.


Next, screw the mounting socket of the handle with self-tapping screws.


And install a decorative trim.


According to the same scheme, is installed and locking handle.

Then we check how the mechanism works.

And the last stage:

Installing a striker on the door frame

To the place of insertion strips into which the lock tongue will go, We put tape on the door. Close the door and mark the position of the tongue with a pencil. We open the door and, in accordance with the marks, mark the position of the strike plate.

Using a drill and a chisel, we select the material according to the marked dimensions of the plank.


Then the bar is inserted, slightly fixed with self-tapping screws and adjustments are made so that the closed door is tightly fixed with the tongue in the strike plate. To do this, remove the bar, adjust it and put it in place. After which the screws are finally tightened.
