Happens to my garage door opener too. My remotes (car, keypad, remote) lose connections at various times and for unknown reasons. Not a big problem, happens maybe a couple of times a year. For some reason they just lose their connection. I reconnect them to the opener and all's fine (for a while). (On my opener, a Chamberlain) I just press the orange button, then the remote, they start talking to one another again and all good.
