Answer 1

Okay, don't know what type of door or lock you have. Is there a saddle type lug that pops out at the top and bottom of the door? It looks like a tiny saddle. These are prone to breaking inside which can stop the whole door locking. The inside (locking) face of the door should be one piece from top to bottom. This whole piece comes off and you can get a copy from a (good) hardware store. Just cut it to length and refit it in the same position as the old one. They're not expensive about £30 or so.

Look on your other post. I have given the answer there.

Answer 3

adjust the cams (on the lock) and the keep (on the frame) loosen the latch plate and check theres a 8mm over lap with the door and the frame if its too much or too less the door wont lock.
