Hi,

I just recently purchased a house with a Craftsman 1/2HP GDO, Model #139.53675SRT2. The house also has the Keyless Entry keypad, Model #139.53684. Both worked fine together until I recently purchased a new opener remote for my car. While programing that remote, I erased the codes in the opener by pressing and holding the red button on the GDO.

Now for whatever reason, I can't reprogram the keypad. I've followed the instructions line for line, but have had no luck. Any thoughts?

Thanks in advance!
