I have a Sears Craftsman 1/2 HP Garage Door Opener. Suddenly, I am not able to use the external keypad (mounted on the wall) to open/close the door.
My remotes on the cars still work.
The battery seems good as the lights on the keypad blink. Neither the instructions in the keypad nor the manual give steps to reset the code.
Does anyone know how to do it?
