Craftsman Garage door Remote Problem (Both door open at same time
We've purchased two new 1/2 hp craftsman garage door openers 3 years ago with 3 remote control buttons on each handheld remote without keypad. We only have 2 garages in our house. Recently I've tried to reprogram one of the handheld remote following the instructions, however the after reprogramming, when I press one botton, BOTH of my garage doors open or close together at the same time. I've tried different button so many times and not sure what I've done anymore. I tried to make sure I pressed the corresponding button during the reprogramming process to the match the proper opener but it still give me the same result. What have I done wrong? Please help.
