Ok, being as there so many replies to my problem and could not respond
to all due to time and the news server being down for 3 days, so thanks
to all who replied.
I decided to follow on my original subject by a new thread, which I
don't normally do.

The problem is the actual lock not moving when the key is inserted into
it to turn/open the lock. It will move so far, ie key turns about 75/85%
and the actual lock does move back slightly, but then key stops dead and
is not possible to move mthe lock back any more.

I have tried Ambersil (which is a very thin lubricating oil) by spraying
it into the keyhole and inbetween the door and frame onto the lock, but
it makes no difference. The lock is solid.
Any further ideas?
Thanks

Leave for some time and keep working at it as the oil will take time
to penetrate and the rust etc requires to be broken down. It took me
2 months to free up a pair of Acrow props that had been left outside.

Talk to a locksmiths/security centre. Sounds like the levers aren't
jamming but the bolt is.

Maybe prying the door up or down a little will help if the door's out
of line. AFAIK powdered graphite is the stuff to use on locks as
lubricant can attract dirt and gum up the levers.

cheers,
Pete.

The advice I had from a locksmith was to cut through the lock bolt
with a thin angle grinder and replace the lock. Worked fine for me.
