20 Most Recent Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+ - Page 8 Questions & Answers

Hi All,

I had the same issue recently and here's what I found out (through a LOT of research) and the solution (yes, there is one!):

As described by many, when you can't get both the remote and the wireless pad to work together it means your garage door opener can accept both rolling code and billing code technology, BUT not at the same time. When you reset all codes (normally by pressing a button on the opener for a period of time e.g. 6 seconds or more), you erase all codes and remote "pairings". Then when you follow the manufacturer's procedure to pair again (which could be the wireless key pad first OR the remote first), the first pairing determines the technology for all subsequent pairings. Example: if your first pairing/programming was with the wireless keypad, and if it was rolling code technology (normally the case for newer models), then the garage opener will only recognize and accept rolling code for subsequent pairings. If your remote(s) are older (billion code technology) then the opener won't even recognize the signal (e.g. led won't blink when trying to pair/program).

And vice versa if you start with your remote after erasing all programming (then your keyless pad won't work).

But here is a potential workaround! For newer wireless keypads (e.g. clicker from chamberlain), you have an option to select the type of opener you are using as you do the initial password set up (normally indicated by a number e.g. 1 for models built after 1995, 2 for models built between 1997 and 2004, etc). Each choice is associated with a technology in the background (e.g. either rolling code or billion code). If you are programming your wireless keypad first after erasing all codes / programming, if you chose the "recommended" option for garage opener, chances are it will be rolling code and that means you won't be able to program your older remotes (billion code) after that. So how can you chose the option that will match your remote???

Here's what you do: start by pairing / programming your older remote first after erasing all codes / programs. That sets the technology (e.g. billion code). Then, go ahead and program your wireless keypad, but you may have to go through the process several times by trying the different options until you find one that works!

For me, I had to try 4 options before making it work. Options 1 through 3 (mind you, options #2 was the exact match for my garage door opener model but it would cause the problem discussed here e.g. wireless keypad would work but not the remotes) would not even be recognized by the opener in this procedure (LED would not blink), but it did work once I hit option 4.

I hope this will help you with your problem. Let me know if it's not clear. Cheers!

Your wires should be color coded blk/ white & solid white you will have a pair for each sensor twist the white wires together and twist your blk/wh wires together now on the back of the opener you should have three screws connect whites to the middle screw a(2) and your blk/white to the third screw (3) your sensors should light up now u should have a solid whte and red/whte connect red/whte to #(1)screw and white to #(2) your wall button should be lite

You should have a power reset button on the backside of unit. Push it in and it should work

Sounds like a spring tension problem. Best toi call a professional as retensioning the springs can be a source of serious personal injury.

I think you need to replace the drive gear. look inside the main housing. if you see white plastic shavings that would confirm the gears are stripped. kits are available for under $25.00. don't buy the one with just the gears, get the new shaft sprocket etc. Not a difficult repair. However, be sure to follow the instructions carefully. the position of the chain & sprocket when you put it back together do matter. Good Luck Steve

When programming a remote, all remotes must be programmed at the same time - including the keypad. Not all Craftsman openers operate this way, but some of the older ones do.

If you mean the wall control just remove it from the wall and the components are accessible from the rear. If you mean a keypad they are not meant to come apart as there is no repair information available for them.

useful info.

You will need to loosen the chain, This releives the pressure and allows you to make the needed adjustment to the limits (at least 2" from the stop bolt).

It is in lock mode. press and hold the lock button for 3 second and it will unlock.

There are step by step instructions for installing a door at this site.

Push the learn button on the opener an then hold the remote under the opener an hold the button on the remote till the lights flash on the opener you have about 10 sec. to do this

You need to reprogram the car remote so the garage opener learns the code

You need to adjust the down travel screw

try replacing the battery and then try your pin no.

Unplug the unit and remove the light bulbs. Using a small screwdriver pull out on the center contact in the light bulb socket.

If you recently changed the light bulb in the unit, try changing it back to a basic clear bulb. I just had the same problem, and after research, found that changing bulb to a new type LED bulb messed up the remotes. A good test, is to try the remotes when the garage door light is "OFF". My remotes worked as long as the light was "OFF". I changed the bulb back to basic bulb, and everything works fine!!

If by "none of my openers will work" you mean none of your remotes and you have the wall control with 3 buttons you need to press and hold for 3 seconds the button with the lock icon.

Humm not knowing more I can guess only that batteries get weaker in the cold.. (like your car battery that will not start in 0 degrees) change the 9 volt battery in both units and try.. Batteries go bad with time so if one is not used it will still detetoriate in strength
