The question of how to embed a lock in a wooden door on their own often arises before those who solve all repair issues themselves. In other life cases, such skills and knowledge can also come in handy, especially since there is nothing complicated about it.
First you have to figure out which doors you need to install a lock on and, in accordance with their type, choose a suitable locking device.
Wooden doors are intended for:
- input
- interior
By appearance and type of operation:
Have you decided on the type of door? Let's start choosing the optimal lock.
Lock selection
There are three types of locks:
A rim lock on a wooden door leaf does not look aesthetically pleasing.
It is better not to find a mortise type of locking device for both interior and front doors. Installing such a lock will require some knowledge and skill, but, if desired, anyone can do it. When buying, you should take into account the direction of opening the door and, accordingly, choose the "right" or "left" lock. There are also universal models suitable for any occasion.
For an interior door, it is better to choose a lock without a keyhole with a magnetic or halyard latch, when turning the handle activates the mechanism.
For sliding types of doors, there are models of locks on sale with a special hook that secures the doors in the closed state.
For entrance doors, locks with bolts are chosen; this is the most reliable type against burglary.
Tools
The first step in preparing for work is selecting the tools that will be needed to install a mortise lock. You will need:
- pencil or pen for marking
- electric drill
- a feather drill, the width of which corresponds to the thickness of the lock
- set of wood drills from 2 to 7 mm
- narrow and wide chisel
- screwdriver
- screwdriver
- hammer or chisel
- tape measure, square or ruler
Making a groove for a lock
- Determine the location of the lock on the door. As a rule, the lock is embedded 1 meter from the floor - plus/minus 10 cm depending on the height of those who will mainly use it.
- Apply the lock to the door leaf with the side that you will cut in, and trace it with a pen or pencil.
- Drill a hole equal to the width of the lock using a feather drill. You can do this in two ways:
- do not drill a hole to the full depth at once, but move gradually 1-2 cm to the required mark in the door leaf
- Drill to the full depth at once, having previously made marks on the drill equal to the width of the lock being embedded. To do this, you can use electrical tape or a piece of wire.
It should be noted that it is necessary to drill 1-3 mm more than the size of the lock body, since it must fit into the drilled groove without obstacles, and the front plate should be completely placed in it.
The drill during drilling must be kept level, perpendicular to the web, so that there is no displacement of the drilled groove.
- Process the groove using a chisel and hammer. Its walls should be as even as possible so that the lock is located neatly inside the door leaf.
- We make markings for the front bar of the lock, if you are convinced that it freely enters the groove. To do this, insert the lock into it and trace the outline of the bar with a pencil. Using a chisel, use a chisel to knock out a notch according to the markings.
Installing a lock and handle
Is the groove ready? Proceed to installing the locking device.
- Make markings for the cylinder and door handle. This must be paid close attention and be careful, otherwise you can ruin everything. Apply the lock opposite the groove and, using measuring instruments (ruler, square), accurately mark the future location of the keyhole and door handle.
- Using suitable drills, make the necessary holes for the handle and the larva.
- Insert the lock into the hole and, if everything fits together, screw it to the door leaf with the screws that should come with the lock. If it doesn’t fit, then continue to align the groove with a chisel and file, not forgetting to constantly double-check how the lock fits into it.
Lock assembly and adjustment
Now you need to adjust the operation of the lock and drill holes for the bolts and latch.
- Insert the cylinder into the lock and secure it with the supplied bolt. Check how it works. If everything is fine, secure the handle and faceplate.
- Lubricate the bolts and latch with dye, close the door and turn the key so that obvious marks remain on the jamb.
- Cut the wood to the required depth of the bolts and latches. Use a chisel to trim the edges to exact dimensions.
- Prepare the recess for the striker (also use measuring tools during this work) so that it is flush with the surface of the box. Screw it on using the screws supplied with the lock.
Everything is ready - you have managed to install a mortise lock on a wooden door. Use the handle and key to make sure everything is level and the lock is comfortable to use. Using a chisel, correct the location of the lock parts if you made a mistake somewhere.
Only mortise locks are inserted into interior doors, since overhead locks will look somewhat bulky and too noticeable on one of their sides. This work is not at all difficult to do, especially for those people who have dealt with something like this at least once. In this article we will look at how to correctly select, install and adjust locks of this type.
Lock selection
The most common type of lock for a wooden interior door is a cylinder mechanism with two round or L-shaped handles and a latch. They are available in several versions, for example, with or without a locking device. In the first case, it is possible to close the door on one side, thereby blocking its opening with the handle on the other side. That is, you can lock yourself in the bedroom and relax without fear that someone will enter the room and find you undressed. A lock without a locking device is installed only so that the door can be tightly closed with a latch, protecting it from drafts, odors from the kitchen or noise from other rooms.
The locking device does not have to be a mechanism with a key. There are also locks that have conventional lockers of various forms embedded in the main handle, for example, levers or buttons. The range of locks in building materials stores is quite wide, so there shouldn’t be any problems with choosing.
The option with a larva and keys is, in fact, a simplified device for locking the front door. Such a lock can usually be unlocked from both sides without fear of becoming a prisoner in one's own office, as is the case when a lock with a block is installed on the door. The tongue in such doors is activated when you press the handle. If the door has the function of a simple barrier against drafts, and does not serve as a fence for personal space (with a locking device), then it is better to choose a lock with a plastic latch. There is less noise from it, which is very annoying at night in the process of opening and closing the door by family night owls.
If you look, then different versions of the devices are placed on the doors of rooms with a specific function:
- Locks with key cylinders on both sides are suitable for offices;
- for bedrooms, toilets, baths and showers - devices with interlocks from the inside;
- for children's rooms, newfangled and expensive magnetic locks are ideal;
- for kitchens, halls and utility rooms, you can limit yourself to ordinary locks with handles and a latch.
But in any case, all devices must be mortise. When choosing, you must make sure that the interior fabrics in your home have the appropriate thickness for the selected fittings. Standard doors usually have unequal leaf thickness: some are at least 35 mm, others are 45 mm. They need appropriate fittings to avoid the lock being as thick as the door.
In addition, when choosing fittings, you need to pay attention to the overall interior of the home and rooms in particular. The door array is also of great importance. For example, it is impossible to embed locking devices designed for a door weighing 40 kg on a canvas weighing 70 kg. It would be a bad idea to embed a lock with miniature handles and a weak return spring into a canvas that has huge dimensions.
As for the magnetic lock mentioned above, such a device has a movable positively charged core (bolt) inside, which begins to operate only when the door is closed. In this position, he finds himself opposite a negatively charged magnetic strip mounted on the door frame. The bolt is attracted by the bar and securely fixes the door in the closed position. To open the door, you need to turn the handle, which disconnects (unlocks) the magnets. After the door is opened, the bolt is no longer affected by the interaction force of opposite-pole magnets, so it returns to its place. A completely silent device is gaining popularity, which is still restrained only by a rather high price for structures of this type.
For sliding interior doors, there are also special locking devices. They cut into the canvas, have the same rotary handles and a bar on the box. The main difference between such devices lies in their latch, which has the shape of a hook, because of which this constipation was called "harpoon".
Preparation
It doesn’t matter which lock was chosen for a particular interior door, preparation for installation is not much different from its type. You can give some advice: if you plan to install locks on all the interior doors of an apartment or house, then it is best to do this on door leaves that have been removed from their hinges. Any professional will tell you this. If you decide to install a locking device in only one door, and removing it from its hinges presents certain difficulties, then it is better to mount the lock in the “standing” position.
Before approaching the door with the tool, you need to carefully examine the purchased model of the locking mechanism, once again check the presence of all the necessary parts and fasteners with the description of the equipment, fully read the instructions and understand the installation diagram of the device. All this must be included with the product.
Armed with knowledge and making sure that the kit is complete, you should decide at what height you will need to install the device. Typically, locks are installed at a height of 100 to 150 cm from the floor surface. Having chosen the height, you can make a preliminary mark on the canvas and think about the tool that will be needed to insert the existing lock.
Required Tools
Let's consider the option of inserting the simplest device with two handles and a latch.
To work you will need:
- chisel;
- electric drill with drills;
- 22 mm feather drill;
- wood cutter with a diameter of 50 mm;
- Screwdriver Set;
- hammer;
- measuring instruments (ruler, square, tape measure);
- washable marker or pencil.
An electric drill is needed not only for drilling holes for fasteners, it is also useful for working with a feather drill and a cutter. You will need to drill a hole for the lock with a feather drill, and with a milling cutter you will need to drill recesses for the decorative overlays of the handles. Of course, it is more accurate to carry out such work with a special tool - a milling cutter, which is designed specifically for such cuts in wood, but due to its high cost, it is more often used by professionals who earn their living from carpentry.
Making a groove
When installing the lock, it will be necessary to make grooves for the latch support plate on the end side of the door leaf to a depth of 3-5 mm (depending on the model), as well as for the back strip on the door block.
This is done with your own hands using a chisel and a hammer using the following technology:
- the planks are applied to their future location and outlined around the perimeter with a pencil or thin marker;
- According to the marked dimensions, the platform is carefully cut out to a shallow depth with a chisel and hammer;
- Then the work needs to be continued, monitoring the depth - it should be strictly according to the thickness of the plates, since neither excess depth nor too shallow a groove is desirable;
- Having cut out the grooves, they are cleaned of irregularities and debris.
In case of excessive penetration, you will have to eliminate the error with a layer of plastic or other material, which, of course, will not improve the operational reliability of the device.
Device installation
Before embedding the lock, you need to make markings. All insertion operations, starting with marking, are easy to carry out yourself. Typically, such fittings are installed right in the middle of the door leaf at one edge. Therefore, a small line using a tape measure marks the middle of the leaf (for a standard door from its bottom this will be a distance of 95 cm or so in any direction). Then, from the edge of the canvas at which the lock will be embedded, use a square to mark 6 cm until it intersects with the previous mark.
A noticeable dot is placed at the intersection of the two marks. It is this point that will be the center through which the axis of the handles and the lock will pass if the lock needs to be assembled with a lock. There will also be a center for drilling a recess for decorating the handles.
- Using the same square, we transfer the central point to the side of the door, right in the middle of the thickness of the leaf. Here will be the center of the cylindrical body of the lock (latch, tongue).
- Now you need to take a feather drill, insert it into an electric drill and drill a hole for the lock body. In this case, you should maintain a strict perpendicular position of the drill axis in relation to the sidewall of the door leaf. The hole depth is about 35 mm.
- It is necessary to replace the feather drill in the drill with a milling cutter. This tool drills a hole for the handles. Here, too, you need to carefully monitor the position of the tool so that it is perpendicular to the door in both the horizontal and vertical planes. In addition, it is impossible to allow through drilling of the door on one side. The cutter has a sharp tip protruding along the axis, similar to the feather of the previous drill, so it will serve as a guide for finishing the work. When this tip drills the opposite side of the blade, then move with the cutter to the other side and drill a hole from there to avoid damage to the blade at the point where the cutter exits.
- The next step is to use a feather drill to adjust the size of the exit hole for the latch. It should be within 23 mm (our drill was 22 mm). To do this, you simply need to adjust the hole to size by inserting and fitting the lock cylinder to the hole.
- After this, it is necessary to clean the resulting two holes, connecting to each other perpendicularly along the axes, from dust, sawdust and burrs.
- We insert the lock cylinder into the corresponding hole and make a groove for its support plate using a chisel and hammer in the manner described above. When the seat for the latch is ready, we install it in place, drill holes for the fastening screws with a thin drill and attach the lock to the door with them.
- Now you can, by inserting one of the handles into the hole in the lock, mark the exact location of the strike plate. To do this, cover the tongue with some kind of dye and, holding the tongue in a recessed state with a handle, close the door completely. After making sure that the door is closed tightly, you need to release the handle, the latch will rest against the door block and make a mark. And already from this mark you can calculate the installation location of the striker. Make a sample for it with a chisel and hammer, as described above. Upon completion of the groove, install the bar in place and secure it with self-tapping screws.
Installing door locks using a plunge router is much better and easier. The milling machine also comes with various templates for working with many known types of locks. With the help of the carriage and these templates, all the work is done on installing not only various fittings, but also on the correct installation of the door itself.
Assembly and adjustment
All that remains is to finally assemble the lock, adjust its operation if necessary, and finally secure all the fasteners. It’s worth noting right away that you don’t need to be too zealous with fasteners, especially in those locks where parts of the device are fastened together from different sides of the blade. Tightening the screws too hard can deform the housing, and the locking mechanism will be difficult to work, even jamming.
Since the latch is already in the right place, it is necessary to insert the handles. The first step is to install the handle with mounting screws, which must be unscrewed before installation. After this, the handle is inserted with its square axis into the hole in the lock and into its own hole in the blade until it stops.

Have you changed your mind about contacting your neighbor? Are you trying to call a professional to insert the mechanism? And you are doing it right! The work costs will be minimal, while the benefits of the new mechanism will be simply enormous.
The cost of a high-quality lock mortise depends on the model and manufacturer. And personal safety and safety of things are the most valuable. In our company, the price for inserting additional locks into a new location on a metal door starts from 2,000 rubles, depending on the complexity of the design.
Imagine yourself sitting in your favorite chair or going on vacation for a few weeks. You do not feel fear, but leave home with complete peace of mind. This will become possible if you entrust us with inserting the lock into the entrance metal door of the apartment.
Mortizing a lock is a rather labor-intensive process, carried out by specialists taking into account many features.
Mortise mechanisms are considered today the best option for ensuring a reliable security system. According to statistics, the vast majority of break-ins occur when simple locking mechanisms are installed on the door. To improve the security of the door, it is necessary to install a lock that has a modern security system. A mortise lock is installed directly into the body of the door, and only the keyhole or latch protrudes from the outside.
The locks are inserted taking into account the design features of the lock, the material of the door itself, as well as other nuances (the presence of a pattern, the specifics of the fit, etc.), so it is better to entrust the work of inserting the locking mechanism to a professional.
A specialist who knows technology and uses professional tools will help you choose the optimal lock model, select the most successful location of the lock structure in the door leaf and perform the insertion itself with high quality.
How to mortise locks
High-quality insertion of locks into metal and wooden doors requires the use of professional tools and specialized devices. This ensures the most reliable and accurate result of the master’s work, in which the door leaf fully retains its original aesthetic appeal.

To install a lock, professionals use a specialized template for inserting locks, eliminating the risk of damage to the door due to a tool that has come off. The template included in the master’s arsenal limits the movement of the tool and allows the position for the lock to be cut out most accurately and efficiently, thereby significantly reducing the risk of damage to the door leaf. The use of templates during work is extremely important, since currently mortizing a lock is performed using high-power power tools. One wrong move can lead to damage to the door leaf.
Locking mechanisms can be inserted into both metal and wooden doors. Each technology has its own specifics, so it is better to entrust the work to a professional. It is easier and faster to embed a locking mechanism into a wooden door than into a metal one, however, even here problems can arise if you do not approach it competently. Thus, an uneven insert can significantly spoil the appearance of the door. Inserting locks into a metal door is a complex, labor-intensive job, which is almost impossible to perform efficiently without experience.
Since the cost of services directly depends on the complexity of the task, the material of the door and the technologies used when inserting a lock into the door, the price of the work may vary.

The Zamok-Moscow company offers professional services for installing door locks.
The insertion of a lock into an interior door is carried out by experienced craftsmen who know all the nuances of technology.
The door lock is an important detail. It performs not only a decorative, but also a protective function, so the requirements for it are high. From this article you will learn how to embed a lock in an interior door yourself.
Depending on the insertion method, ease of use and other characteristics, the following types of locks are distinguished:
- Flat, having a rectangular frame and tongues separated from the latch of the lock. The design is highly reliable and is equipped with a push handle (halve).
- Round locks in a cylindrical body, latch with tongue combined. The handle can have any shape. The stopper and the cylinder cylinder of the lock are inserted into the spindle.
- Reduced size flat locks equipped with a rotary handle. The latch is missing.
- Round, in the design of which there is a special knob handle.
Castles can be classified according to other criteria. The types of locking mechanisms are as follows:
- bolts;
- fall;
- latches with lock;
- mortise type;
- invoices;
- magnetic.
The last type of locking devices does not create a sharp sound when closing, it can be mounted in any interior door (even already installed); Magnetic locks are becoming increasingly popular.
To insert a lock into a newly acquired door, you need to know the thickness of the canvas and the features of its structure. There are these types of interior doors:
- MDF 35 mm wide.
- MDF 45 mm wide.
- Wooden door of a new design (panel width from 50 mm).
- A wooden fiberboard door of an old design with a plank frame.
You can install locks on interior doors yourself, knowing the design features and operating principle of the lock.
Flat
This category of locks is the most expensive. They are more difficult to install, but provide good burglary protection. They put additional load on the door, unlike round locks. The flat latch will fit the existing door.
It is permissible to install only flat locks of reduced size on a door made of MDF with a width of 35 mm. Also, only those locks whose widest tongue is 15 mm are allowed to be embedded in MDF. The end plate must not exceed 24 mm in width. This is due to the fact that only a wooden frame can bear the dynamic load created by the lock, and MDF is a weak material.
Round
This type of locks is most suitable for an apartment or residential building. They are designed to fit into any door. The push handle is most often used in homes where people with limited mobility live. Using the rotary handle requires more effort.
The knob handle is distinguished by its safety: it is impossible to get hurt or get caught on clothes.
The installation process for round locks with any handle remains the same. The lock mechanism with a cylindrical body is produced for doors whose thickness is 35-45 mm. Locks for large wooden structures cannot always be found on sale in small towns. But round locks are different in that they can be adapted to any door thickness. To do this, you need to replace the latch carrier by installing a longer one. It is a rectangular steel plate 2-3 mm thick. There is a hole at one of its ends.
The latch exit toggle switch must be placed in a position that will correspond to the material from which the door jamb is made. For wood it is 70 mm, for MDF – 60. The production of locks for interior doors has its own characteristics: their cylinder is located inside for the convenience of locking the door from the inside.
When the door opens to the left and a suitable lock has not been found, the latch and cylinder must first be swapped. To do this you will need to disassemble the structure. This option is not suitable for office premises, because such a lock from the cylinder side is easy to disassemble even without the use of special tools.
Preparatory stage
The insertion technique depends on the design of the lock. The easiest way to install is the latch handle. For this purpose, a hole of the required diameter is carefully made. (Craftsmen recommend carrying out all finishing and installation work after the floor repairs have been made.)
Installing an interior lock with a rotary lock (or with a handle and a cylinder) is more labor-intensive: it will be necessary to make a nest at the end of the door leaf, as well as 2 holes for the cylinder and the handle.
It is necessary to correctly calculate the height at which the handle will be installed. When choosing a wooden door, there are no restrictions on this parameter. On a frame structure, the handle should be embedded at the location of the cross beam, located at a distance of 90-100 cm from the base of the door leaf. The thickness of the vertical beam varies depending on the thickness of the door leaf.
Most often, the lock is installed in an installed door, but you can cut it in before installation. When it is planned to make a recess for the lock using a manual electric router, the blade must be firmly secured in a lying position using a slipway, turning the side to be processed towards you.
Lock Mortise Tools
To install the locking mechanism in the door, you need to have the following tools:
- Pencil for marking.
- Joiner's triangle.
- Roulette.
- Screwdriver complete with a set of bits.
- Screwdrivers (flat and Phillips).
- Feather type drill, 6 mm wood drill, crowns of the required size.
- Hammer and chisel.
- Bit.
- Slipway.
- Manual electric milling machine.
There are special tool kits that include all the necessary drills and crowns.
Mortising a lock with a milling machine
The lock should be attached to the canvas, having first retreated a distance of 1 m from the floor. The handle can be located at a different height depending on the wishes of the owners. Now you need to determine the depth of the insert: using a triangle, measure the body of the mechanism and mark the required depth with a simple pencil; trace the upper part of the device along the contour.
Then you should choose a location for the keyhole and latch. The locking device is measured from the end to the center of the keyhole, and markings are made on the door. After this, the holes for the keyhole and latch are drilled using a feather drill.
Then marks are made for the future recess for the lock. To do this, it should be leaned against the end side of the door with a crossbar. A cutter of the corresponding circle is inserted into the router, after which the recess is drilled. Care should be taken to ensure that the crossbar completely fits into the door leaf.
Then you need to cut a recess for the lock structure. A groove cutter is “loaded” into the router, with which the groove is cut. This must be done so that the locking mechanism fits clearly into it. The boundaries of the recess should be processed with a hammer and chisel to give them an aesthetic appearance.
It is necessary to remove the shavings from the recess and then place the lock there. The crossbar strip is attached using self-tapping screws to the side of the door, and then the door hardware is installed.
Mortise a lock without a router
To install the locking device manually, the following tools are required:
- pencil;
- ruler;
- roulette;
- electric drill complete with drill 10-14 mm;
- chisels of different widths;
- round files.
It is necessary to count from 70 to 100 cm from the bottom edge of the canvas and mark the future location of the locking mechanism. Having placed it sideways, you should mark its inner part and note the width of the rear plane of the structure. After that, according to the markings, we drill holes. Then you need to drill holes deep into the door. To do this, hold the drill at a slight angle.
Using a chisel, you need to level the surface of the socket so that the mechanism can fit into it. Having attached the lock to the front part of the blade, you should mark the position of the handle and the core, drill holes and align them using files. Repeat the same process on the opposite side of the door. The structure is inserted into the groove, then a rod is threaded onto which the handles are attached.
The locking tab is exposed. Marks for the tongue are placed on the door jamb, a recess is made under it with chisels, where the mating part of the lock (bar) is placed. The bar is secured, after which the lock is ready for use.
Marking
Before installing a door lock, you need to figure out how to correctly mark the required type of locking device.
Most often, markings are applied using templates or corresponding parts of the locking mechanism that are applied to the door. It is recommended to draw lines using a sharp awl or needle to work directly along the contour. When using a pencil, you will need to take into account the width of the drawn line and its distance from the part. This is not easy to do even for a professional.
It is forbidden to use a mechanic's scriber for this purpose, since the indentation from it is even greater than from a pencil, and it is impossible to erase scratches after it. The door will need to be repaired.
Round
First you need to determine the place where the round lock will be located, after which you should mark it using the installation instructions and template. The distance from the floor should be 965 mm. This side of the marking should be applied taking into account the thickness of the door and the length of the lock tongue. Marking is applied from the side of the larva.
When marking two points on the front part of the door leaf, it is necessary to retreat from the end edge of the door 60 mm (for the first point) and 70 mm (for the second).
It is necessary to mark a hole on the door leaf, the diameter of which is 50 mm. It is intended for a pen. The second hole is made at the end of the door, opposite the main hole. It is 23mm in diameter and is designed for a snap-on design.
Flat
On the door jamb, the vertical and then the horizontal axis are marked with a pencil. The latter is applied at a height of 965 mm from the floor (for structures made of solid wood and older specimens - 800 mm). Marking is carried out according to the attached lock using a pencil. You must select a slot for the lock along the marked line. As a result, it will turn out a little larger than necessary. This will create the necessary gap for installing the mechanism.
There are some peculiarities when marking the recesses for the cylinder and the spindle: it is done by attaching a lock to the side, while the holes are made with an additional indentation from the door end. These holes should be equal to the width of the end plate.
Flat lock mortise
If the door is made of wood, then the lock can be inserted anywhere. If the door is made of MDF, then the locking mechanism must be embedded at a level of 1 m from the floor, since the location of the wooden beam inside the hollow door is at this level.
It is preferable to drill a hole for the lock using a feather drill, the diameter of which exceeds the thickness of the lock structure by 1-3 mm. It is best to drill through pioneer holes in 2 passes.
Then we select the nest with a chisel and make a hidden one (after marking its outline along the embedded lock) according to the instructions.
The shaped recess for the larva is performed in the following steps:
- Drill a larger round hole for the cylinder.
- Drill a round hole of smaller diameter for the bottom of the pin cassette.
- Using a chisel, remove the remains.
After this, you can insert the lock into the door. To do this, you need to remove the handle and larva from it, and then insert it into the socket. After this, the fittings are installed back. The assembled loose lock should have a play of 1 mm on all sides.
Now you should identify and mark the holes for the screws. When the places for the screws have already been marked, we drill holes for them according to the markings. Having attached the lock structure to the door with their help, you need to install the handle and the lining under the tongue.
Handles can be round or L-shaped. To install the handle, you must:
- Install decorative overlays on both sides of the canvas, securing them with self-tapping screws.
- Insert and secure the handle bar.
- Close the door and make a mark on the frame where the tongue is located.
- Determine the length of the tongue using a ruler and make appropriate markings on the box.
- Attach the overlay to the marks and trace it.
- Drill recesses along its boundaries, bringing them to the required shape using a chisel.
- The final stage: the cover is inserted and secured with self-tapping screws.
You should check whether the door opens and closes easily. If necessary, the location of the tongue can be changed.
Lock mortise with cylinder
The insertion of the locking mechanism with the cylinder is carried out similarly to the previous option. Having made marks on the door end, you should drill a vertical strip of recesses located as close to each other as possible. You can remove the jumpers by using a chisel. A nest of the required size should be prepared. A hole is drilled in the door leaf for the cylinder (or rotary key) and handle on both sides using a crown.
After this, a chisel is used to make a selection for the lock plate, and the locking device, handles and the counter part of the bar are mounted.
It is best to carry out this work using a router: problems may arise when using other tools, such as a chisel and chisel. A hand router allows you to achieve smooth surfaces with the smallest errors. In this way, it will be possible to maintain the aesthetic appearance of the door.
Round lock mortise
To drill holes according to the markings, you need to select a crown of the appropriate diameter. It must be calculated so that the hole is covered by the outer casing of the device. But the circumference of the recess should be sufficient for the installation of internal mechanisms.
In specialized stores you can purchase kits for inserting round locks. They consist of 2 crowns of the required diameter.
Having prepared the necessary tools, you can begin drilling the hole according to the previously made markings. To prevent the appearance of cracks, splits and other deformations of the door leaf, you should make a hole from 2 sides down to the middle. Then you need to make a hole in the end of the door in the same way, into which the mechanism will be placed. The strike plate in the door frame is installed in the center of the drilled hole for the tongue.
The device should be placed in the finished socket and traced around it. After this, the latch is pulled out. Using a chisel, you need to make a hole large enough to fit the outer plate. This work should be carried out with care so as not to exceed the required hole depth and not damage the side of the blade.
Now you can install the mechanism, checking that it closes correctly (you can read in detail in the instructions for how to install a lock on the door).
