The door has a border which is about 1.5cm raised from the door. The door has a barrel slide lock however because of the raised border there is no place to put the latch. This is why I initially just made a hole in the border and the sliding piece of the lock would just go into this hole.
The hole has now failed as a bit has broken off and therefore the sliding piece no longer catches in this hole. The door no longer locks.
What are my options in this situation? Is there any way to patch the hole so it locks again? If I was to re-install this and use a latch instead of the hole how would I go about raising the sliding piece to the same level (1.5cm) as the latch?
This is essentially what the lock mechanism looks like , im sure this picture will be much clearer than any picture i take with a camera.
