I have a one year old craftsman opener with 2 remotes and a keypad. I tried holding the smart button in and reprogramming the remotes. The main pad on the wall just blinks. I tried to unlock per the owners manual and nothing seems to work. I get no help from sears, they tell me they would need to send some one out which would probably cost more than a new opener. Im at a loss. Any suggestions would be appreciated.
