I have spent ages trying to find out what the name of this lock is (deadlock, deadbolt, mortice bolt) and it seems that the correct term is a mortice bolt, like this:

The locks are both very old and need replacing.
I was wondering whether, for added security, there might be a straight replacement that allows them to be locked from both the inside and outside.
