Replacement lockcase for garage door: There are many different makes and types of lock that fit to up & over garage doors. This one had a half euro cylinder in it to lock and unlock the door and a handle to release the two latches on the inside holding the door shut.
This lock had failed and was refusing to lock / unlock with the key. When taken apart there was a broken bit of cast metal which makes it impossible to repair 100% reliably, so a new lockcase for the garage door was needed.
It never ceases to amaze me how many different styles, types and sizes there are of essentially the same lock for the same job purpose.
This lock manufacturer name was Novoferm.
