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

1 Answer

Chamberlain liftmaster keypad works when open but not when closed

Starting a few weeks ago, the keypad to my 1/2HP Chamberlain Liftmaster would only work when the door is open. Due to this, I changed the 9V battery inside the keypad, but this didn't help. Both of the remotes in my two cars still work fine, but 99% of the time, the keypad will only work to close the garage door, but will not open it if it's closed. I say 99%, one time--which was first thing in the morning--it did open it when it was closed...but that was the only time. Please let me know what you think...

To program the keypad, first unplug the garage door opener from the electrical outlet. Next remove the nameplate from the console that the keypad plugs into and locate the program/operate switch. Flip the switch to program. Next enter your desired four-digit PIN number into the keypad. Slide the switch back to operate and plug the garage door opener back in. The keypad should be programmed.

Make sure the battery is good and then locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release this button and then walk over to the keypad and key in a 4 digit code and press enter.

Wireless keypad closes door but won't open door. Just started this about a week ago. I replaced battery, still no luck. Car remotes work fine.


You keypad has lost signal strength. It has enough to work when the door is open but not enough to penetrate the door. A replacement is needed.

Wireless keypad will close door but open


WHEN YOU CHANGE THE BATTERY YOU NEED TO REPROGRAM THE UNIT.

IF THAT DOESN'T WORK YOU PROBABLY HAVE A BAD KEYPAD.

HOPE THIS HELPS
