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.

You shouldn't need to reprogram the pad; it functions as before simply sending a signal to the opener that has the programing saved in it.

Sounds like you may have a bad battery if the keypad was working before you replaced it. If the keypad did not work I would suspect it has failed.

Do you mean the numeric keypad is no longer controlling the garage door? If so, have you changed the battery for the keypad? Frequently, if the battery is low, the keypad will stop working when the door is closed but works to close an open door. On most Chamberlain garage door openers, this is a 9V battery. You may need a small Philips screw driver to open the battery compartment at the bottom of the keypad.

After changing the battery, try the learn code procedure again. I've found it easiest to have two people involved when programming the keypad to the garage door opener. One handles the Learn button and the other types in the desired code.

I hope this helps.

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.
