Posted a while ago about installing my first lock and got some helpful advice, I'm a bit stuck though. I've installed the Yale deadlocking rim lock (the really buig chunky one) and its all gone quite well apart from one fairly major thing.
the cyllinder has been screwed to the door from the inside and the back plate of the lock itself is ready to be attached to the door. there are several woodscrews which attach the backplate to the door and two, long, flat headed screws which attach it to the actual cylinder. when I tighten these two screws the key wont budge in the lock. at the moment they are screwed in but are very loose. they can't really stay like this, as if they worked looser they could stop the lock from turning all together and then I'd be locked out and totally stuffed.
I've hacksawed them to the minimum length as the instructions suggest but still when I tighten them to any degree the key won't turn in the lock.
what am I doing wrong??????
any ideas from people who've installed this lock before or can figure out what I'm on about?
