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

1 Answer

Garage door opens on its own with new Chamberlain "Clicker"

I have the exact same problem. I bought a Chamberlain "Clicker" remote last week and set it up. I too now have a garage door that opens at no certain times of day, just "whenever" and not every day. I also went with the dipswitch remote and had the same problem just this morning. My garage door is also 1990; Craftsman 53000 SR model.

This cannot be just a coincidence. I also don't think it is a short in the system. Can someone help?

Often times, keypads and remotes are not compatible with newer models, even with the same manufacturer. If you are still interested in finding an instruction manual, try the Chamberlain website. You can also purchase a Universal Keypad, which will work with most models.

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.

Universal garage door remote


I have a feeling your neighbor operated their door opener when you were programming your new clicker. Try erasing the memory of your opener and then program the clicker again making sure your neighbors do not operate theirs at the same time. To erase the memory hold the smart/learn button in for 10 seconds.

Liftmaster Professional and Clicker Programming Problems


The Security+ system is a rolling code system and is digital, so it will work with the Homelink in vehicles and with the remote control units that come with the opener. Also with new remotes that are purchased specifically for that opener. Your "clickers" require specific instructions and you need to use the Smart Learn function in order to use them with this opener. In addition, check the Brand Switch settings to be sure they apply to your opener, and the correct Smart Button color on the opener. Read carefully to determine whether you need to set ANY dip switches at all or can you just set them all to off depending on your opener? Check the instructions carefully. Here's a link to the page where you can download a copy of the Clicker instructions if you don't already have it:

This web address came from the Chamberlain site. I also needed to relearn my remotes due to a newer car that has a built in garage door opener that needed to be set. I also needed to reset my keypad remote, those instructions I was able to get from the same site. Good Luck
