I’m trying to replace the lock on my composite door. It has a multipoint mechanism with a euro cylinder and an internal thumbturn. I’ve run into a few issues:
On the outside there’s a circular escutcheon. On the inside I can twist the matching escutcheon off, but the external one won’t budge.
It doesn’t seem to twist off like the inside plate.
I can’t see any retaining screws from the inside holding it in place.
When I removed the interior plate, the tiny screws I found were just fixing into the door skin, not holding the cylinder.
On the inside, I can’t slide the escutcheon plate past the thumbturn. Maybe that isn’t necessary, but I wasn’t sure if there’s a way to detach the thumbturn knob so the plate can be removed.
So far, I've removed the long retaining screw on the edge of the door (the one that secures the cylinder in place).
I've turned the thumbturn to around 25° so the cam should line up.
At that point I was expecting the cylinder to slide out, but it’s stuck and won’t move.
Does the external escutcheon need to come off to release the cylinder?
Is there a trick to getting the thumbturn plate off from the inside?
Or is the cylinder just being pinched by the fittings/escutcheons and I need to wiggle/loosen more?
Any advice appreciated
