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

1 Answer

Keypad code will close the door but not open it.

Our keypad entry and remotes have been working fine for about 5 years. Now when we enter the code into the keypad it will only close the door. The door will not open by using the keypad. We have already replaced the batteries. Any suggestions?

Check that both codes (in the remote & garage door opener) are the same. Press reset on the opener and reset enter the code.

Tried to reprogram security code for outdoor key pad on 1/2hp craftsman garage door opener according to instructions online, pressed learn button- put in new 4 digit code-held enter. Lights did not flash...


Seems you've done everything right. Press and immediately release the smart/learn button and then walk over and key in a 4 digit code and press enter. If you are sure the battery in the keypad is good then I think your keypad is on the fritz or the wrong one for that opener.

Model 940CB/67LMTrouble free for 10-12 years. Now with a new battery after code + enter it will flash about 60 times very fast will not open the door. The door opener works fine with the button on the wall...


You can try programming it but I have a feeling it is bad.

Locate the smart/learn button on the rear of the motor unit. Press and immediately release this and then walk over to your keypad and key in your 4 digit code and press enter.

If this doesn't work you will need a new keypad.

Craftsman Model 139.53684 Keyless entry doesn't work


The remotes and keypad use the receiver which is part of the logic board.'t The button on the wall is hardwired and doesn't use the receiver. You might pull the logic board and check for bad connections on the printed circuit.

Can enter code on keypad to lower garage door, however keypad just "flashes" when code is entered to raise door


If your other remotes are working normally I would suspect first of all a weak battery in the keypad. Secondly the keypad could be getting weak and the closed door blocks enough of the signal to cause your problem. An open door lets the signal through. Normally during the time the keypad is flashing you can hit 'enter' again to reverse the door if it is closing or stop the door if it is opening.
