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

1 Answer

Door opener remotes not opening garage door.

We recently changed our pin code to our garage door. After doing so, our remotes no longer work. I though the remotes were synchronized to the frequency of the opener itself and that the pin code should not have effected the remotes. Help.

    Problem solved! It's just as simple as pressing the transmit button on the remote, then a small LED light will flash on the side of the opener itself. There is a button next to this flashing LED light. Press the button next to the flashing LED light on the garage door opener. The flashing LED light will go solid; it is now synchronizing the remote to the opener. Once the two have synchronized, the LED light will go off and actually turn on the garage door light. Push the transmit button on the remote and the opener will work.

You have to sync the remotes to the new code. For older remotes, you can open the remote and match the pin settings.

For newer remotes there's a button that you push in the back of the opener that sets in program mode (for Chamberlain). When you push the remote button, it will acknowledge the remote is programmed.

If this doesn't help, comment back on your particular model and we'll help you with the solution.

How do I check a wireless garage door keypad, to see if it is transmitting?


These remotes don't loose the programming code when a battery goes dead, most likely the remote or the board on the opener went bad, do any other remotes work? You can take the remote to an auto parts store and test it there. (They have a tester for key fobs)

I would recommend this. I'm not sure this will work, but I think it will.
Try starting from scratch. Reprogram the unit to the car again, I think the codes change each time it is done. If not, it's not too difficult to try.

Hardwired code opener no longer works


Here are the directions to program your hardwired 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.

You might possibly have held the smart/learn button in too long and erased the code for the remote. Hold the button down on the remote and then press and immediately release the smart/learn button. This should program it for the remote. Now make sure the keypad is still working.

Reset garage door code


Hi, The opener, remotes and keypads have a set of dip switches that you can use to change the code. You will find the switches when you open the remotes and keypad and are in the back cover ( depending on the model) of the opener itself. Make sure that the codes of all the switches are set exactly the same. If you need additional help let me know! Good Luck.

unplug the power of your door opener for a few minutes and plug it back in. Try the remote control that you have and see if it opens the door. If it doesn't open the door, reprogram [learn] the remote control you have and that is it. The other remote will be useless ... and you just proved it to yourself!

Garage door keypad & remote


You need to sync both. I have a LiftMaster. If you want to change the code on your keypad you need to open up the garage door motor compartment where the light is (mine is in the back). Press the learn button, within 30 seconds enter the new code on your keypad and hold down the enter button for several seconds until the light on the opener blinks to tell you it has learned the code. Test the new code to see if it works. If the new keypad code works, then try the remote. My remote will not work after I reprogram the keypad. If the remote does not work (check battery) then climb back up the ladder and press the learn button on the garage door motor again, press the remote button and hold down until the light blinks again and the opener has learned the new code. This process works when I need to sync my remote and keypad. Good luck, I hope this helps.
