Craftsman 1/2 HP Garage Door Opener - Only one works!
I have a Craftsman 1/2HP Garage Door Opener Model 139.53681B
(with a RED button). The batteries for on of the remotes died so i replaced it. When i reprogramed the remote, i can only get one to work no matter what i try.
I tired unplugging the GDO, reseting the codes, no matter what, i can only get one to work at a time. Mind you both have been working together for the last 5 years. When i changed the battery now only one works. I've been desperatly searching the web for an answer to my problem.
Does anyknow know how to get both remotes working again? I read the other posts and it seems like the member GDS knows what he's talking about. Do you have any ideas?
Thank you so much!
