Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
YOU MOST LIKELY HAVE THE WRONG REMOTE.
THEY HAVE CHANGED THE FREQUENCY OF THE OPENERS.
BE SURE TO CHECK THAT THE REMOTE YOU PURCHESD WILL WORK WITH YOUR OPENER.
IF THE LED NEXT TO THE PROGRAM BUTTON FLICKERS WHEN YOU PRESS THE REMOTE - IT IS SENDING A SIGNAL.
HOPE THIS HELPS

the smart/learn button on the rear of the motor unit near where all

Post back with your results.
