My sears gargae door opener quit working with the remotes.

The remotes quit working along with the garage door code. it won't reprogram. I also checked the lock mode and its off. When I put the lock mode on the lights flash until I take it off. But the only way the gargae door will open is with the hard wire.

Took the side off and blue off the board, and re-connected all the wires and conections. It then started working again.

The remotes for my craftsman garage door opener will not reprogram. the light on the rear of the unit does not blink when I try and reset / reprogram the remotes.

I think you are saying everything except the Klik2 has quit working. If that is so check to see if the light in the wall button is blinking. Press the 'lock' button for 3 seconds and the light should glow steadily and the remotes will work. If you are saying all remotes plus the Klik2 has quit then your logic board has failed.

My garage door remote will work for a day or two then it quits and then I have to reprogram it, and it works another few times and stops

If you only have one remote it could be it or the receiver that is quitting. No way to tell without another remote to test it.
