I’m also a fan of the S&G but I have several digital.
So when you change just the keypad, can you use the code programmed on the old one or do you use the new code that came with a new lock?
The security info is not in the keypad, it’s in the part inside the safe.
Otherwise you could open any safe by plugging in your own keypad.
I really don’t understand why keypads go bad; car electronics which are way more complicated last essentially forever.
