I have a Hormann up-and-over garage door which is unlocked but I do not have the key so I am trying to change the lock.
I’ve watched videos on Youtube and it looks easy, you just unscrew the screw on the right and then the lock slides out. Except it doesn’t. I remove the screw but when I try to remove the lock there is something inside stopping it from coming out.
I’ve opened up the grey box which it’s in but couldn’t see anything immediately obvious holding it in place.
Any ideas on how I can get it out?
