garage door opener remote
I have a craftsman 1/2HP GDO model 139.53964SRT, with 2 remotes model 139.53681B, and 3 button premium control panel, and remote keyless 4 digit keypad. All Purchased new and together on 6/2003. Both remotes lost range and acted up within 1-2 weeks of each other, I thought the batteries may be old, they were both replaced. I have tried reprogramming the remotes per instructions in my manual, but no success. The manual says with the door closed to press and hold the button on the remote, press and hold the light button on the door control, press and hold the door control push button - the lights on the opener should flash once when it has learned the code, mine never flashes. I have tried this procedure unsuccessfully with both remotes. I have also held the SRT button for 6 seconds to erase all remote control codes prior to performing the above procedure with no success.
Both the keyless 4 digit pad and premium control panel both operate normally. Only the remotes do not function.
