How to Change a UPVC Door Lock
- 1). Buy a new lock for your door of the same size as your old UPVC door lock.
- 2). Remove the old lock by unscrewing the bolt that holds it to the door with a flat head screwdriver.
- 3). Place the key into the lock and turn it to the side a little. When you feel that the key is firmly positioned in the lock, gently move it around a little bit to pull out the whole cylinder of the lock.
- 4). Put the new lock into the hole and tighten the lock bolt from the side. Be sure to place both the lock and the bolt in the right position.
- 5). Tightly screw the bolt of the new lock with a screwdriver. Close and open the door to check if everything is working as it should.
