You might try programming it but I think it is bad.

To program locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release this and then walk over to your keypad and key in your 4 digit code and press enter.

If the small light in your wall control is blinking it is in the lock mode. Press and hold for 3 seconds the button with the icon of a lock. This will toggle the lock function off.

My keypad works,my remote opener does not, even


It is related. One of the buttons on your wall control is the lock button and has a lock icon on it. Press and hold it for 3 seconds. The blinking should stop and your remote should now work.
