Can not reprogram GDO Craftman 139.53674
I bought the house 8 years ago with this opener. It has a Premium wall Console and two Security+ remotes.
4 years ago I bought a car with built in universal remote capability, and (believe it or not) I was able to program it.
Now I've sold the car and tried to use the old remotes. They don't work, and can not reprogram the system. I have followed the instructions:
1- erased the codes (hold the Learn Button for 6 seconds)
2- Press and hold the Learn Button, press and hold the remote button. The light holds steady for a few seconds and turns off, never blinks and the remotes don't work.
3- Also tried the one-quick touch to the GDO button technique, it did not work either.
The batteries are good. It puzzles me that I can't reprogram either remote; the system worked fine with the car I just sold so I assume the receiver is working fine.
Any ideas? the 1-800 number only has recorded answers that don't help me.
