What will I need?
A screwdriver,
A hammer
How do I switch my cylinder lock?
- Open your door. Now you have an open view onto the latch and the deadbolt with which the door is securely locked. Below the deadbolt, there is a retaining screw that holds the cylinder tightly in the mortise lock. You will have to first loosen it (do not yet remove it).
- Now insert the key into the existing lock. Turn the key gently in the clockwise direction to approximately 1 o’clock. Now remove the retaining screw completely and you will now be able to quite gently pull the cylinder out with the inserted key.
- In the next step, the new key is to be inserted into the new cylinder. Turn the key far enough that the so-called “tappet” no longer projects and it will be possible to insert the new cylinder into the lock without any problem.
- As the final step, reinsert the retaining screw under the deadbolt and tighten it. Now your new cylinder is ready to use!
