I have a Sears Garage Door Opener with Security + and have two remote controls that came with the unit. One quit working - I changed the battery and tried to reprogram it and it would not connect.
Funny thing though - when I erase all remote control codes I can program the one that wouldn't work but then the other one won't program. I've repeated the process several times so it seems that all of a sudden the unit won't accept two remotes. Anyone have a clue what my be causing this?
