I was having a problem with the remotes. Program one remote, and the other stops working and vice-versa. I found the solution to be as follows: Using 61LM single-button remotes for Lift-master WhisperDrive (belt drive) garage door opener, I set the dipswitches (find them by removing battery replacement cover) to identical settings in both remotes. Set the first dipswitch to the neutral (0) setting. Next -- and this is the important part -- press the learn button on the main door opening unit, and, while the small LED light is lit, press the button on ONE of the remotes. DO NOT REPEAT ON THE SECOND REMOTE. Upon doing this, I found that BOTH remotes at last worked. I then went on to program a keyless entry pad, which was accomplished by again pressing the learn button on the main unit, and then entering the number sequence I had chosen for my entry code on the keypad, and pressing Enter. Both remotes continued to function and the keypad functions as well.

what keypad are you using with new opener? Frequency has changed. can't use old one. you probably never needed to change things; just needed to follow proper coding procedures.

The radio frequency has been changed so the two are not compatible.

To answer your question the opener is in vacation mode. Press and hold for 3 seconds the button on your wall control with the lock icon. The green light will stop flashing and you will be back in business.

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.

Remotes quit working on Craftsman 53975 garage


It sounds like you have a logic board problem. If your remotes work at all it is not a programming problem. You could pull the logic board and check for loose connections especially around the small transformer. 18 years for an opener is very lucky. Their average life is about 1/2 that.

Cant get 2 remotes for garage door openers working at same time


You have a remote that has reverted to an earlier technology. The only way out of this is to purchase the same exact model number called for by your opener and go through the programming. You will find the new one will work with one of the old ones. Remove the battery from the one that isn't and drop it in the garbage.
