craftsman opener / remote keypad issues
I have a Craftsmans garage door opener with 2 remote openers and 1 keypad entry mounted outside the garage door. The problem I am having is I can get both garage door remote openers to work but not at the same time. When I get the 2cnd one programmed the 1st one don't work anymore. And I cannot get the keypad to work at all. I have the book and the instructions for reprogramming seem pretty easy but it's just not working. The keypad worked fine before I started messing with the remotes.
Any ideas ??
