Both remotes won't work for Craftsman garage door opener model 139.53672SRT1


You will need to purchase a new remote with the same model number as your old ones. When you get this you will find that you can program the new one with one of the old ones but not the other. Remove the battery from the bad remote and discard it.

Cannot reset remote to garage door opener Sears craftsman 139.53681B


If you are sure the battery is good then try to program the remote by holding the button down on the remote and then pressing and immediately releasing the smart/learn button. If this doesn't work and you have another remote that does work then the remote has quit working.
