I want to know how to replace a lock that is in a (unlocked) uPvc door.

The word Yale is on the lock, it is probably eleven years old, and from
what can be seen of the lock whilst it is in the door, its shape looks
like a standard Euro profile cylinder lock. It operates top-and-bottom
shootbolts. Protruding from the door edge is a small triangular cam which
engages on a striking plate on the door frame. When the door is closed,
this triangular cam is depressed, releasing the door handle so it can be
lifted upwards to position the shootbolts (the cam mechanism is very
difficult to get to work at times).

However, there is no long screw at right angles to the lock, holding it in
place, as might be expected with a current Euro profile cylinder. There
is instead a hole in the door frame where the long screw, if there was
one, would go through. At the bottom of this hole I can just make out
parts of the lock which rotate as the door handle is rotated.

Can anyone identify this lock, and tell me if it can be replaced with a
Euro profile cylinder, and how?

(I have asked Yale but so far have had no response.)


Sounds a bit odd, having said that, a few years ago I came across a euro
cylinder that had been fixed with the screw from inside the frame prior to
the glass being installed.
Good luck..
