How to Disassemble a Key Lock
- 1). Open the door so the lock can be reached on both the inside and outside of the room. Inspect the lock and locate all of the screws holding it in place to the door. Remove all the screws with a screwdriver.
- 2). Remove the inside lock by pulling it out of the door once the screws have been removed. Pull off the outside part of the door lock and set them both aside.
- 3). Remove the cylinder from the knob by inserting the cylinder removal tool and releasing the springs holding the cylinder in place. Take out the springs and slide the latch assembly out of the mounting hole.
- 4). Remove the screws holding the strike plate in place and remove it from the lock to completely disassemble the lock.
