Start with this:
This electric strike was poorly installed and it, along with the keypad installed with it, was no longer working.
This strike was an incorrect size and was not cut in to fit flush and tight. This caused the door to close improperly, leading to the eventual destruction of the system.
This is the latch which was locking into the aforementioned strike. It is poorly installed and ugly. In the lock business, ugly usually means poorly done and of short service life.
Tape? Is that tape I see in this photo? Yes it is. This is the mounting stud for the emergency exit paddle. Held together with tape. I promise, I do not stage these photos!
Sometimes it is better to just start over and do things right.
Finish with this: A new keypad was installed along with a secondary bolt and lock status indicator for additional security. More photos to follow.
