Craftsman Garage Door Opener
I have a Craftsman garage door opener - model # 139.53977 SRT that was installed professionally when my house was built 5 1/2 years ago. For some reason, the keypad that the kids use to get into the garage after getting off the bus stopped working.
I thought it was the battery and replaced it - didn't do the trick. I thought maybe it was the pad and that through continued use, weather, etc. it was not functional and bought another one and installed it.
So, I did the smart thing and read the instructions several times to try to determine what I was doing wrong. I couldn't find anything that I was doing wrong, so I started from scratch by pulling the plug on the garage door opener, and set about resetting the 2 cars and the outside wall mount unit remote access.
However, I can't get the 2 cars and the wall mount pad to reprogram - I can only get 1 at a time to work. After the first one works, the second car and wall mount won't reprogram.
Anyone have any ideas?
I appreciate any responses.
