Welcome to FTE!
Besides the thread luxury posted, there is another one with 30-odd pages of posts. Good reading if you're insomniac, in prison, confined to bed, etc.
Just help you stop looking, AFAIK, some early Ex's do not have the code # recorded. So go to the link/post#17. I did a cut n paste and printed in a larger font, got my wife to read while I punched in the #'s. 10 minutes & 20 expletives later the lock popped open !
The keypad is a great feature, we use it a LOT.
