There is a large group of threads from as far back as 2000 about the Craftsman garage door openers. I just posted a message there about problems I'm having. Maybe posting here will get more notice.
My problem is simple- both the key pad outside the garage and the remote control quit working simultaneously. They had been working fine and I loved having keyless access to my house. I replaced both batteries and have tried looking on the motor/gearbox for 'reset' buttons and instructions on how to reset the code. So far nothing has worked. My key pad buttons blink incessantly when I try to press a code. The remote control opener does nothing.
