Identifying the door lock
Look along the face plate of your door lock (where the locking points are) until you locate the manufacturers name or logo. On GU multipoint door locks you will see “GU” stamped on the face plate.
There is an old version of this multi point door lock. You will see GU stamped on the faceplate. The old version was used until the late 90’s, after that period the new version was introduced. If you have the old version, the easiest way to fix the lock is by changing the lockcase, as the positions of the locking points are slightly different on the new version (Link to Old Gu Lockcase)
