You can try programming but if it still doesn't work then your keypad is just bad. Locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release it and then walk over to your keypad and key in your 4 digit code and press enter.

I reset my liftmaster/chaimberlain keypad (976LM) and now can't access garage. Is there a default code? No other access into garage (new owner to this house).


Make sure the battery in the keypad is good. You cannot reset the keypad without access to the opener. You will have to find a way into the garage.

A door technician uses a special tool to pull the emergency release after drilling a small hole in the door. The door can then be lifted without damaging anything. A keyed manual release assembly is then installed in the hole to be used if there are problems in the future like a power outage or malfunction like you have now.

The inside button is hard wired. The keypad is a small radio transmitter. If the battery in the keypad is good and it doesn't work when you put in the code it has probably just quit.

Mounted keypad will not open garage door when I enter the code


Make sure the battery is good. It isn't uncommon to get one that has been on the shelf for a long period. If you still have the same problem and your hand remotes work okay you keypad is bad.

Keypad does not work when I just change a new battery, no light


Make sure the battery is good. anytime you change the battery you need to reprogram the keypad.

Press and release the square button on the circuit board. You then have 20 seconds to input the desired code and press enter.


Hope this helps
