Mechanical Code Lock - Changing the Code

Mechanical Code Lock

This guide provides instructions on how to change the code for a mechanical code lock.

Changing the Code

Remove the door housing.

Unscrew the 2 screws to remove the door housing.

Press the C button fully.

Remove the back plate.

Turn the housing with the buttons and unscrew the back plate. Handle the plate carefully to prevent springs from falling out, then place it on a table without the springs.

The rider heads appear.

The rider heads appear, some colored red or blue, and one neutral colored head (the C button). The rectangular recesses must all face outwards from the housing; otherwise, the riders cannot be fully inserted.

Neutralize All Codes

Using the small pliers, remove all red and blue riders.

Note: The rider on button C, whose head is not colored, must remain in place.

IMPORTANT

When removing or placing a rider, constantly press the C button.

The code lock housing could be severely damaged if these precautions are not taken.

Choose a New Code

Place the red-headed riders in the slots corresponding to the chosen numbers or letters, respecting the insertion direction of the riders.

Place all remaining blue-headed riders in the free slots.

Reminder: Always remember to press the C button.

Reassemble the Housing

Reassemble the housing and verify the correct combination.

Before replacing the housing, check that the new code functions correctly after pressing button C.

Before replacing the housing on the door, verify that the new code functions normally after pressing button C.

Ensure the correct functioning of the lock.

After reassembling the housing on the door, place the 2 screws in their slots and tighten them.

Before closing the door, verify that the new code functions normally after pressing button C and the bolt.
