Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+

1 Answer

We have Craftsman garage door openers for both doors on our double car garage. The problem is with our keypad and our remotes in the cars. The keypad and car remotes work fine for one side of the garage, but not the other. The pads inside the garage to open and close the doors both work fine. I have replaced the batteries in the car remotes as well as the keypad battery. Any thoughts?

It sounds like the logic board has quit working on the one opener. If you have had lightning or power surges you might remove the logic board and check for loose, burnt or missing traces on the printed circuit.

your car remote should work even from inside the garage... if not, just take it off the visor and go outside the front door and point it at your garage to open it. This is only a quick fix. You probably need to replace the batteries in your keypad or reprogram it.
