My front door won't lock properly. It is quite a new door as in under 5 years old. There seems to be a gap at the top lock. I usually have to pull the handle up quite hard and slam it to close it.Not good I know. I know it wil eventually not close at all soon.
your door has dropped it needs heal and toeing.
if you keep forcing the gearing to lock it you will knacker it.
there are adjusters on the hinges try them
