I can't get my older garage door remotes to program with the new unit.Do I have to buy new remotes?


SORRY TO SAY.THE ANSWER IS YES.
THE NEW OPENERS ARE NOT ON THE SAME FREQUENCY.

YOU CAN PURCHASE REMOTES THAT WILL WORK WITH BOTH OLD AND NEW OPENERS (DUAL FREQUENCY).
BUT, OLD REMOTES WILL NOT WORK WITH THE NEW OPENERS.

Which Keyless Entry Pad should I purchase for the Craftsman 1/2 HP garage door opener model # 53920 ?


The only models I can find that are close to yours are 53920D and 53920DM which are fairly new. They both call for keypad model 53754.

Remote control unit does not open the door. we


Hi,
You can try reprogramming the remotes to the opener that is not working. Sometimes they get a brain freeze and drop the codes and reprogramming can fix it. Next to where the wire hangs down will be a colored square button (the learn button) press once and release, you have 30 seconds to try and program a remote, you don't need to do all in the 30 seconds. Press and hold the button on your remote that you want to use until you see the light on the opener blink or hear a click sound from opener, let go of the button. it should now be programmed. If you can't get any of them to work then the logic board is bad.This repair can cost as much as a new opener + install. Sears sells a "remote control conversion kit" it comes with 1 remote and a plug in receiver you attach to your existing opener. 2 wires come off it and hooks up where your wall control hooks up at the openr.It's pretty easy to install. FYI the remote controls are color coordinated meaning the buttons on the remotes have to be the same color or they won't work, so if existing remotes are not the same color as the one in the kit they will most likely have to be replaced. good luck!

Intermittent remote trouble


Your wall control is hard wired and doesn't use the receiver portion of the logic board. The remotes do. Your receiver is going bad.

I have a crafsman opener #139,53879. Installed an outside remote on door and now the factor opener will not work.


Sounds like your outside remote may be the wrong one for your opener. Program your original remotes and you will most likely find your outside remote will not work. The model number for your opener is on the opposite end of where all those white wires go. Use it whenever you need to buy anything for your opener.

Code Remote and other remotes do not all work at the same time.


Either your keypad has reverted to an earlier technology and will no longer work properly with your opener or you have the wrong keypad. Either way take the model number off the main unit and get the correct keypad.

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.

Remote does not open garage door


It sounds like the wall button has the lock feature engauged.

Is there a small green LED flashing inside the wall button?
Push and hold the lock button for about two seconds and the LED should stop flashing. This will unlock the garage door opener and your remotes should start working. You may have to reprogram your remotes and homelink again since you triedprograming in the lock mode.

Good luck.
