Cutting locks for wooden doors: description and installation

Often as doors to enter residential apartments use models of wood array. They are strong enough, well retain heat and protect the room from excessive noise. In 90% of cases of unauthorized penetration in the dwelling, not the doors themselves, and castles. Based on this, it is more expedient to purchase a good castle of a mortise type for the existing wooden door, than to change it to the steel model.


Docking mechanisms on the doors are mounted in three ways, for which the models of locks are separated.

  • Currency. Locking device is mounted directly inside the door of the door. Is the most versatile and safe view of the locking device.
  • Overhead.
  • Hinged.

In our article, it will be discussed precisely on mortise locking mechanisms. To begin with, consider the benefits of using mortise devices.

  • The mechanism hidden in the body of the door complicates unauthorized access to the larvae and the bollard of the castle.
  • Protection of the lock mechanism from falling into it dust and sera.
  • Conservation in the inviolability of the appearance of the door, which is especially relevant for products decorated by valuable wood. Outside, only the well of the castle and the door handle are visible.

Disadvantage: Cutting Castle can be installed on the door only once, when the mechanism breaks, you will have to replace the door or carry out the capital repair, alone the niche for the lock device.


The most common types of mortise locks for wooden doors are the most common:

  • cylinder – the most reliable and affordable models in the installation;
  • Suwald – distinguished by a high degree of counteraction to hacking;
  • code;
  • Electromechanical.

Systems based on rotary cylinders are distinguished by reliability and ability to resist hacking. In addition to these advantages, high-quality cylinder locks have a very large margin of safety and wear resistance. Also, simplicity of attachment and uniformity of the size of the castle larvae contributes to the rapid replacement when breakdown or the wrench. Cylinder lock devices differ in small dimensions. The durability of the cylinder mortise lock is achieved due to the use of brass and high-strength guides.

The second place in popularity is occupied by the Suwald key devices. The mechanism is based on the use of several Suwald – special code plates that are shifted only by a key with a suitable profile. Suwald mortise locking mechanism perfectly resists the power autopsy and cutting locking bolts. Produce models with the possibility of transcoding – it is very convenient, because when the key is lost, you do not have to dismiss the entire locking mechanism. The procedure itself of transcoding during its experts takes only 5-10 minutes.

Code locks are mounted as follows: The main part of the mechanism is placed inside the door of the door, and only the code plate with numbers remains outside. The constipation opens a predetermined digital combination. From the outside, such a locking mechanism cannot be disassembled. This type of locking devices are more often used in offices and manufacturing enterprises. They are distributed as locking mechanisms of access doors in apartment high-rise buildings.

In addition to the above types, hidden locking mechanisms with electrical or electromagnetic elements are used to lock the wooden door structures. The mechanism is cut inside the door body and connect to the command board. The basic condition for mounting the mortise blocking device is a good disguise to its location. Often electromechanical blockers combine with a cylinder mortise lock.

In addition to blocking mechanisms, in the door of the tree you can cut the combined locking devices with a drive of shut-off riggers on power supply. These types of shut-off mechanisms require an electrical cable. When the current is supplied to the solenoid coil, the reiguel connected to the core is drawn into the mechanism and the door opens.

In the absence of electric current, the rigleels are in the grooves and the door is closed. That is, if you crop the feed lock cable (with unauthorized penetration), the mechanism is not unlocked. Here can only help the native key. When you lose it to replace the locking larva. Such locks cannot be opened with the help of the knee, because the hacker will not be able to predict the behavior of the mechanism on the cylinder shift.

How to choose?

Choosing a door lock, first determine what door he needed for you. For interior doors, it is better to choose a simple mortise lock or latch-lock. For the entrance doors, you can choose both an overhead locking mechanism and mortise, but the security of housing is already started to play a big role. That is, for the doors of apartments, houses are better to choose a mortise locking device of an elevated security class. These are cylinder, suvalid models, as well as electromechanical, code lock devices.

You can put on interior doors both just latch and a full castle with a rigle and latch. If you chose a lock only with a latch, keep in mind that they are mechanical, magnetic and falev. Fallet latches open-closes the door under the action of the handle. Magnetic clamps support the closed door of the door using the magnetized elements that attract each other.

Rigels in the castles also differ in shape: they are straight and hooked. The first type is used for opening doors, the second – for sliding door structures, to counteract the unauthorized shift of door flaps. Table of comparative characteristics of locks of various safety classes.

The procedure for the installation of the mortise castle of various subspecies is almost the same. First of all, pick the instrument set to trigger the lock.

  • electric drill with suitable drills or milling device;
  • Pencil for marks;
  • chisels (narrow and wide);
  • Screwdriver and screwdriver;
  • a hammer;
  • Measuring device (roulette, line and t. NS. );
  • Screws (screws, screws).

Choose a convenient location of the key mechanism, usually cut into the door at an altitude of 1-1.1 m from the floor surface. Applying the castle, on the end facet of the door and the jamb, apply the markup of the location of the mechanism and the response. If you have a milling device, your task is to cut the groove under the lock greatly simplifies. The quality of the work done, however, will reduce the likelihood of damage to the door of the door.

Remove the door with the loops (if it is already hanged on them), turn it out the end side and fix in this position. The location of the future lock is placed by two scotch strips (painted). Insert the cutter into the milling device and adjust the depth of penetration into the door body. Then make a groove. If you have an electric drill, drill two recesses along the top and bottom mark on the depth and width of the key design. This can be done by two methods:

  • Do not deepen immediately for the entire amount, and gradually, 1-2 cm moves deep into the desired mark;
  • drill immediately deepening the required value, for this on the drill to make tags with a tape or a piece of wire.

Take into account that the dimensions of the deepened deepening must be a couple of millimeters more than the dimensions of the inserted lock. The case of the mechanism is obliged to be located in the groove together with the front strip without the obstacle. Maintain a strict perpendicularity of the drill relative to the door body to prevent displacement. Treat the resulting deepening by the chisel and hammer. Get the maximum loving walls of the groove. Then place the place of the front strip. Insert the lock into the recess and supply the bar of the pencil. According to the resulting contour, you knock out a small deepening.

Next, the location of the well and knobs should be outlined. Apply the device to the door of the door opposite the recess and using the line as much as possible to mark the position of the handle and the well of the castle. Drill with a suitable drill size drill holes for them. Now insert the locking mechanism in the groove and if inconsistencies are not detected, attach it to the body of the door with screws included in the device package. If you have found some inaccuracies, align the deepening of the chisel and a file, constantly testing the accuracy of the input of the lock mechanism.

The next step is the debugging of the functioning of the lock and the preparation of grooves for retractable riggers and latches. Insert the larva of the lock of the castle, attach it to the screw, which is included in the kit, test it functioning. If troubleshooting is not visible, fasten the door handle and front bar. Latch and retractable rigels cover the paint, cover the door, turn the key to make traces from them on the door frame. Cut the grooves under the latch and riglia, hang the edges of the chisel. Extend deepening under the retaliatory bar. Attach her screws included in the lock kit.

Check the lock operation – twist the handle, check the key several times there and the key. If the lock works without a number, there is no distortion anywhere, it means everything is in order. If you have discovered shortcomings, we work a bit with a chisel and a file to align the location of the parts of the locking mechanism. As you can see, the independent installation of the locking model of the lock in the wooden door is quite simple and quite forces to each. To reduce the probability of troubleshooting due to inaccuracies of the procedures done, test the functioning of the mechanism at each stage. Remember that accuracy and care in work – half of success!
