I have a garage door with a red auto-learn button that is used by several people. I would like to remove a single programmed remote from the opener without deprogramming all the other remotes that are currently in use. Is there a way to deprogram a single remote? Can I reset the remote itself back to factory default?

When I search, all I can find is instructions on resetting the garage door opener itself by pressing and holding the learn button until all the programmed remotes are deprogrammed, but that requires everyone to reprogram their remotes. I would like to avoid this.

The remotes are GD-R12 three button Generics design to replace 973LM by liftmaster.

  • Liftmaster does not provide instructions for doing this, you have probably already searched their website. As they are the authority on their systems and we are not, asking here is redundant. VtC Apr 19 '21 at 18:25

    I don’t see a reason for a down vote. There are tricks out there sometimes but not in this case.

  • It seems like there would be a way to erase the memory in the remote itself so it loses its sync with any receiver.

    Because the remote doesn't have "memory" in that sense. It has some for the rolling codes used in newer systems (since ~2000 or so), but the remote doesn't remember the opener, it's the opener that remembers the remote. In your situation, I would suggest that you reset the garage door, then reprogram it with all the remotes/buttons that need to open it, leaving the communal gate alone. You may have one remote with the "wrong" button opening the gate, but you'll get used to it quickly without annoying everyone else in the condos.

    Since, however, this is likely a commercial system to open the condo gate, there may be a way to get it to "forget" a specific remote. However, without exact details on the make/model, there's no way for any of us to search the internet for you. Your best bet, anyway, is to call Liftmaster and ask them. BTW - the first thing they'll ask for is the model #, and possibly even the serial # of the unit in question.

Yes you can remove one.

Steps:

  1. Grab remote that you want to remove.

  2. Take out batteries (if there are any).

  3. Sit remote on driveway.

  4. Beat it with a hammer.

  5. Test remote and make sure it doesn't work!

  • @FreeMan - It's actually the easiest way. The remotes are $8. So if you decide you don't need one anymore and don't want it getting in wrong hands you destroy like you would an unused credit card.

They all have to be reprogrammed.

When you teach the system you add remotes 1 by 1.

To remove 1, all remotes are erased from memory. they have to be taught 1 by 1 again sorry.

    I had the old pin setting ones. I miss those and I heard they were actually more secure.
