CHECK TO SEE IF THE LED IN THE WALL BUTTON IS BLINKING - IF IT IS PRESS THE LOCK BUTTON AND IT WILL STOP THEN TRY TO PROGRAM YOUR REMOTES.

IF IT IS NOT BLINKING TRY UNPLUGGING THE UNIT FOR ABOUT 5 MINUTES - PLUG IT BACK IN AND TRY TO PROGRAM THE REMOTES

HOPE THIS HELPS

There is nothing to do beyond what you have done. You need to get a new keypad. Make sure you get the same model as there are some out there that will not work with your opener.

One of the buttons on your wall control has an icon of a lock. Press and hold this for 3 seconds and release. The blinking should stop and your remote should work.

Check the wall control. If the small green light is blinking press and hold the button with the lock icon for 3 seconds.

This web address came from the Chamberlain site. I also needed to relearn my remotes due to a newer car that has a built in garage door opener that needed to be set. I also needed to reset my keypad remote, those instructions I was able to get from the same site. Good Luck

Reprogram the remote. Press the learn button on the back of the opener and then press the remote button until the light on the opener blinks once.
