At all stages of installation, check the operation of the lock. A slight deviation when marking or cutting out can spoil the operation of the locking mechanism. Below is 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 location for the door handle. Attach the locking mechanism to the mark and trace the outline.
Step 2: prepare the hole

Step 3: Marking up
Insert the lock into the canvas and make marks for future fastening. Drill to make holes for the bolts.
Step 4: install the knob

Installing a mortise lock for a wooden door
The preparatory stage of work is similar to the installation of a locking element in a metal door. You also need to mark the place of the cut and circle the outline. The process then proceeds in several stages:
- A groove is cut with a pen drill. The hole must 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 nicks, it needs to be trimmed with a chisel and a hammer.
- Clean the groove from sawdust and insert the lock there.
- Apply the striker to the end and circle it with a simple pencil.
- To make the bar flush, make a notch with a hammer and chisel.
- Take out the lock and attach it to the side of the door. With a ruler, measure the place under the handle and the keyhole. Drill holes in the marked places.
- Try on the castle. 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 composition that is easily washed off. Close the door and turn the key and then open. There will be a trace of paint on the door frame. This is where the latch will go.
- With a chisel, make a groove under the tongue. The second bar also deepens flush, like the first. It should run flush with the canvas.
- The whole structure is fixed with bolts.
If all the steps were followed during operation, the mortise lock should open and close without difficulty.
