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

1 Answer

Hi, my neighbor recently purchased Sears opener #53985 (1/2 hp) chain drive with remotes & keypad. I did the installation and everything was fine. Then about two weeks later she said the keypad no longer worked. I checked it out and it seems the opener lost the keypad signal. So I pressed the learn button on the opener and reprogrammed the keypad. Everything's now fine again. My question is what caused the opener to lose the keypad signal?

This is not something common and there is no known reason. If it happens again have her contact Sears for warranty service.

The conversion kit you purchased from Sears will work with any door opener and has the latest security feature but the bad news is your keypad will not work with it. If you want a keypad you must make sure it is 315 mhz and Security +. It would be Sears latest model.

Make sure your neighbor doesn't have a remote with a sticking switch. Often times a person will stick an extra remote in a drawer and then place something on it that holds the button down. Try programming your remotes this way just in case you didn't.

Press and hold the button down on the remote while you press and immediately release the smart/learn button. Sometimes it can help if you are in the garage when you program your remotes this way and it will drown out any distant signal.

Have your neighbor bring over his remote and open or close your door with it. Then hold the smart/learn button in for 6 seconds on your opener. Then see if he can open your door. He shouldn't be able to because that procedure erases the memory in your opener. No remotes should work. You need to get that remote #53778 back and program it and then see if your neighbor can open your door. If he can open your door at any point after you have held that button in for 6 seconds you need to get a new door opener.

If you haven't yet, double check the wiring on the back of the motor unit. A wire could have broken or just come loose. If your opener is new it will be in warranty.

According to Sears your model number is bad. Double check the number and they will have the owners manual with complete installation instructions.
