Did you wipe out the codes in it.. It will only hold 3 or 4 code, not sure which.
See your manual, I think you hold program button down ten seconds to wipe all out. Then reprogram. Of course, should not have happened in first place... May be a board problem.

If this does not work you should follow instructions for warranty service. That might be your best course anyway. warranty it, else it may happen again after warranty expires.

This problem was exposed on a popular news program some ten years ago. There's a number code inside the remote that you have to change, and set the garage door opener to the same code. It should solve the problem.

Opener keeps losing code


YOU MAY HAVE A LOOSE BATTERY CONECTION IN YOUR REMOTE.

ANYTIME THE BATTERY CONNECTION IS LOST (EVEN MOMENTARILY) YOU WILL NEED TO REPROGRAM IT.

IF YOU CAN'T FIND AN OBVIOUS PROBLEM WITH THE BATTERY, I WOULD REPLACE THE REMOTE.

HOPE THIS HELPS

Remote does not open garage door


It sounds like the wall button has the lock feature engauged.

Is there a small green LED flashing inside the wall button?
Push and hold the lock button for about two seconds and the LED should stop flashing. This will unlock the garage door opener and your remotes should start working. You may have to reprogram your remotes and homelink again since you triedprograming in the lock mode.

Good luck.
