I have recently changed the barrel on a Yale lock (with the remainder
of the lock components remaining in place). However, since putting
everything back together, when the door shuts the bolt does not travel
fully into the keeper because of some resistance. The keeper hasn't
been touched and the lock fits well on the door, so I can't see what
has changed to create this issue. I removed the barrel completely
(with the long screws and fixing plate which holds it in place) and re-
attached the lock, and the same happens, so I can't see it's related
to replacing the barrel in any way. When the door is open the bolt
moves freely. It's almost as if the keeper is too close to the rebate,
but I'm fairly sure the problem wasn't there originally. Any ideas?
