Has anyone had one quit responding or intermittent response? I searched the forum and went back 2 years and didn't see any similar posts but my 4 1/2 year old remote seems like it's failing. It will quit responding, then interment response then respond for a while then repeat the cycle. Batteries are fresh and it's not just one or two buttons either, the entire remote doesn't respond. I know a new one is a quick call away but has anyone "fixed" a failing remote?
