My front door will not close and lock properly.

When I try to lift the handle to engage the locking mechanism the top bolt
shown here in the closed position will not move properly

This bolt will not move into the locked position as shown here

unless if I apply a small upwards force on the bolt when lifting the handle
(which is not possible when the door is closed) or use brute force on the
door handle.


Any ideas?

I have managed to shut and lock the door shut tonight using force but it
will need repairing ASAP.
