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

1 Answer

Some reason keyless entry won't open my garage door. I have directions to change the code but, there is nothing in the manual if your code no longer works. I have changed the battery, pulled the plug on the garage door. Nothing seems to allow me to put in a new code. 139.53674 Garage door / Keyless Entry 139.53684 Purchased in 1997

If that keypad quit after working since 1997 and a new battery didn't get it going it has just gone bad. The model number listed for your opener is now 53876.

SOURCE: Reset Craftsman keyless entry pad.

What you are asking for is not possible. You need to call a garage door repair technician. They will drill a hole through the door and using a special tool can pull the rope to release the door.

SOURCE: 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.

You can try programming it but first make sure the battery is good. Locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release this and then walk over to your keypad and key in any 4 digit code you like and press enter.

Often times, keypads and remotes are not compatible with newer models, even with the same manufacturer. If you are still interested in finding an instruction manual, try the Chamberlain website. You can also purchase a Universal Keypad, which will work with most models.

Coding the keypad will not affect the remotes if you follow these directions.

Locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release this and then walk over to your keypad and key in a four digit code and press enter.

We have a Chamberlain Whisper Drive Plus. The keyless entry stopped working, suddenly. I have changed the battery, not the problem. I cannot get it to work, and cannot get it to reprogram. The keypad lights up when buttons are pressed, but when I press "Enter" the whole keypad flashes for about 30 seconds and then just goes dark.

Keylees entry and remote controls do not work at the same time


There are two types of technology with this operator (rolling code and non-rolling code). This operator will except one or the other but not both. It is not uncommon for a rolling code (Security+) remote or keyless to lose the "rolling"part of its technology and become a non-rolling code device so it is not compatable with the rolling code technology. You will need to replace the one remote or keyless that is not like the others.

Change keyless entry passcode for chamberlain model 4100 door opener


You have to press a Yellow/Purple button on the back of the garage door opener unit.
It is the LEARN button. Then enter a new four digit code into the keypad and press the enter button.
The unit should click and the lights should flash. This acknowledges it has learned the new code.
