Question about Chamberlain 950CB Remote Control

1 Answer

I need to reprogram my old LiftMaster opener, after 15years my neighbor who claims he hasn't had any changes to his garage door, now can open mine. I can reprogram a few different remotes but they all appear to be receiving the same old code so neighbor can still open it????

Not sure if you have deep switch or smart learn button. In first situation you need to change the sequence, in the other, pressing the learn button for more then 30 sec should reset and erase all remotes from opener memory..

SOURCE: have chamberlain security plus 950cb lost instructions.
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

SOURCE: Locked out & Remote not working

There should be a green button on the back of the motor unit, press it for 2 seconds and then hold down your remote button until the light flashs. or for 3-5 seconds and then activate the remote. that might solve your problem

SOURCE: my chamberlaain security + garage door openers

well your main PC board inside of the opener head could have lost the frequency, or the unit memory has been erased, try to reprogram the remotes by going to the back of the opener head and locating the "learn" button which is either red, green, or purple in color. press the learn button then ONE button on ONE remote, pressing multiple buttons or pressing both remote buttons at the same time will not allow them to be programed successfully. after programing test by pushing the same button you just programmed, repeat for other remotes, and if this process did not work than you will need to contact chamberlain

Why does my garage door opener, opens my garage door and my neigbors at the same time?

Check and make sure it is erasing the code. Before reprograming squeeze the remote it shouldn't do anything on your opener. If after programing, it still does it, erase the codes in your neighbors opener and reprogram it. This might sound crazy but after all of that and it still does it you have a bad circuit board.

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.

Bought a universal remote for craftsman/sears garage door, now our neighbors can open our garage with there universal how do we stop this

I would go ahead and change the password on the remote and then I would REPROGRAM the remote with the garage door mechanism. It is supposed to have a rolling code. Perhaps your neighbor,s password is coincidentally the same as yours. Stranger things have happened. Below is a link to your instruction manual on-line.
Hope this helps,
Best Regards,

This problem was exposed on a popular news program some ten years ago. There's a number code inside the remote that you have to change, and set the garage door opener to the same code. It should solve the problem.
