    You either research it on the Internet and try to follow the complicated directions to re-program the opener, or else you call a technician and pay for it to be done.  Try first to do it yourself based on YouTubes and instructions on the Internet.

    is something blocking the sensors?  check for anything in the way, gently clean them with an alcohol wipe
