Keypad code erased after teaching new remote


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 the recycled remote is Security + there is no logical reason the new units should not work. If the old remote is a different technology and there have been changes to the opener or a different receiver that could be the problem.

I have a craftsman 139.53651 installed in 1994. It has the learn button for programming new remote codes. Reading through the manual and the Internet, there is no way to reset the code, it only stores one...


I think you are going to be stuck for a new opener. This is highly unusual but does happen. You are right about not being able to change the code. You can erase the codes but once you program it you have put the same codes back in. A new opener will be on a completely different radio frequency and should end this.

I have an old craftsman 139.655000 garage door and i need to program a new remote to open the door. how do i know what remote to purchase?


There are no remotes available for that opener. Your best bet would be to replace that opener with one of the new state of the art units that are so much safer.

If you didn't, try programming the remote this way.

Press and hold the button on the remote and then press and immediately release the smart/learn button on the motor unit. If this doesn't work you need to make sure you have the correct remote for the model opener you have. Your model number doesn't bring any results from Sears Parts.com.

Craftsman 1/2hp garage opener Homelink must be under unit to work


Have you tired reprogramming the remotes to the opener?

The opener receiver board may have failed, which happens. You can order a new one from Sears or other places on the Internet, and they are fairly easy to replace.

Once replaced, you will need to program the receiver to you remotes again.

When did your remote and keypad quit working? Was it when you programmed the Homelink? It sure sounds like you have a bad logic board.
