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

1 Answer

The wired keypad (Chamberlain) of my garage door is not working. The red light on the keypad keeps blinking. Can someone tell me how to fix that? FYI, the garage opener, the remote, and the wall unit all work fine. I've changed the battary, but it did not help.

    When you say "wired keypad" is it the unit with keys numbered 1 through 9? Does it have wires running to it?

  • houyang89 Mar 14, 2011

    Yes, it has wires running to it from a wall unit just inside the garage door. The wall unit is connect to the motor by a wire too. This must be a very old set up (not the new wireless ones, definitely not the 976LM). I meant to post a new question, but somehow the title was assigned.

You can try programming the keypad using the procedure below.

To program the 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.

It sounds like there might be a loose wire connection on the inside of the sensor. You could also be moving the position of the sensor slightly into alignment when you squeeze the sensor. You will need to disconnect the wires for the sensor on the garage door opener or disconnect the power. Then use a flatblade screw driver and carefully seperate the sensor case. Check for any loose connections on the wiring(you might need to re-solder the wire to the sensor eye). It sounds like a loose wire connection to me.

Chamberlain Garage Door opener model 3850. Sometimes the keypad will not open door. Instead the lights behind all the numbers blink in unison. What is it trying to tell me? Thanks Jim


The blinking lights are normal when you enter a code and press enter. I would try programming it and if that doesn't work replacing it. To program it you press and immediately release the smart/learn button on the rear of the motor unit and then key in your 4 digit code and press enter.

Press and hold for 3 seconds the button on the wall control that has an icon of a lock. The light should quit blinking and your remotes will once again work. Holding that button for 3 seconds toggles your openers vacation mode.

Have you tried programming it? Hold the button on the remote while you press and immediately release the smart/learn button on the motor unit. You will find the smart/learn button just to the left of where all those white wires go.

Chamberlain garage door opener unit-is it compatible with craftsman keypad?


Hello,Linda well this is your lucky day ,I have installed garage door openers for sears for 10 years and i can tell you that craftsman,chamberlain ,and liftmaster are all the same machine and manufactured under the liftmaster name , if you buy it from home depot it will be a chamberlain ,if you buy it at sears ,it will be a craftsman, and if you go to commercial building supplier it will be a liftmaster! now getting that out of the way even though they are all compatible ,there is one thing that stands in their way and that,s time ,For example if your chamberlain machine is 5 years old and you went to sears last week ,the chances of the frequency being the same are not good , most likely you have the wireless keypad , one way to test the sears keypad against the chamberlain machine is to locate the smart button on your machine ,this button allows for programming of remotes and keypads , to test and see exactly what im talking about take your remote and locate the smart button ,if you have three buttons on the remote press one of the buttons that are not being used on the remote ,above the smart button their will be a blinking light ,if you press your remote button you will notice the light go from a blink to a rapid flash , This is telling you that you are sending a signal for programming to the machine , well the keypad is exactly the same all you have to do is push the enter button on the keypad and have someone watch for the rapid blinking light ,if they are compatible the light will blink rapidly on the machine so all you have to do now is have someone press the smart button once on the machine your indicator light will now be a solid light you will have approx 60 seconds then to put a 4 digit code in the keypad and then press and hold down the enter button on the keypad , at this point you will notice the lightbulbs on the chamberlain machine to shut off and come back on this is to tell you that the machine accepted the code , after thats been done you can use your keypad , you can also find the owners manual to the chamberlain and follow the same instructions to programming the remote , they are identical in programing , if your keypad is not the same frequency you can also tell by looking at the frequency code on the backside of the keypad and also the chamberlain unit usually where the light bulb is will be its code

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.
