Hi.

I've just got home from work today, and my door lock seems to be
catching for no apparant reason!?

What happens, is that the latch that would normally open when you pull
the handle down is sticking inside the actual door, so that when it is
pushed to, it cannot latch onto the door frame and shut to. I can push
at the top of the latch to make the latch come back out, but cannot
find any way of making it so that it doesn't do this. I've tightened
all the screws I can see (all on the outside of the door, as cannot
seem to get to any inside of the door), but it is still doing it.

Anyone any ideas on what I can do to fix this?

Cheers,

David


Yep, start with lube--graphite or molybdenum
disulfide. If that doesn't work then look at the
mechanism. Start with the screws that hold the
plates (screws should be on the in-house side of
the door). Loosen them and move the plates a bit
to see if that helps. If not, open the door, lock
the door, and remove the screws and the plates so
you can actually see the latch mechanism. Could
be something just doesn't get lube or could be
that it is broken. Good Luck
