If you need to install a mortise lock for a wooden or metal door, it is not necessary to contact a specialist. You can do it yourself. For work, you need only a set of special tools. It is important not to rush and carefully follow the instructions.
How to choose a mortise lock:
- The element should not occupy more than 30 percent of the width of the end of the front door, and 70% - interior.
- Purchase the device in special departments with a guarantee.
- Locks can be right-handed and left-handed. To choose, you need to know which way the door will open. If you have not decided on this parameter yet, then you can buy a universal element. In this, you can change the position of the latch.

Training
Correctly insert the lock on the door removed from the hinges. Otherwise, you can damage the awnings, and the door will stop closing.
Place the canvas on the end, propping up with wooden blocks. The latter can be covered with a cloth so as not to scratch the surface of the door. At all stages of installation, check the operation of the lock. A slight deviation when marking or cutting can ruin the operation of the locking mechanism. Below we will take a step-by-step look at installing a mortise lock for a metal door.
Step 1: determine the location
Before proceeding with the installation, it is necessary to determine the location of the locking element. From the bottom of the canvas measure 1 meter in height and put a mark. This is considered the most convenient arrangement of the door handle. Attach the locking mechanism to the mark and circle the outline.
Step 2: prepare the hole
How to install the mortise lock? The recess is drilled with a drill. In the resulting circled rectangle, you need to make holes. Remove remaining nicks with a file. It is important that the lock fits tightly into the socket.
Step 3: do the markup
Insert the lock into the canvas and mark for future fastening. Drill holes for bolts.
Step 4: install the handle
Attach the lock to the door leaf. Measure on both sides of the place where the handles will subsequently be installed. Drill and insert it into the body of the door. Screw in all parts with a screwdriver. Make holes and install handles. Secure the locking strip.
Installing a mortise lock for a wooden door
The preparatory phase of work is similar to installing a locking element in a metal door. You also need to mark the place of cutting and draw a outline. Further, the process goes in several stages:
- A feather drill cuts out a groove. The hole should be 2 mm larger than the width of the lock. Thanks to this, the mechanism will effortlessly enter the well.
- To make the hollow smooth, without chipping, it must be trimmed with a chisel and a hammer.
- To clear a groove of sawdust and to insert the lock there.
- Attach the locking bar to the end and circle it with a simple pencil.
- To flush the bar, make a notch with a hammer and a chisel.
- Remove the lock and attach it to the side of the door. Use a ruler to measure the place under the handle and keyhole. Drill holes at marked points.
- Try on a lock. If deviations and other errors are noticed at this stage, they need to be corrected.
- Install the larva in the keyhole and secure with the screws that came with the kit. If everything works, you can screw the bar.
- Lubricate the latch with a coloring compound that is easily washed off. Close the door and turn the key, then open. A trail of paint will remain on the door frame. This is the place for the latch to enter.
- Chisel to make a groove under the tongue. The second bar also goes deep flush, like the first. It should go flush with the canvas.
- The whole structure is fixed with bolts.
If during operation all the steps have been followed, the mortise lock should open and close without difficulty.
