That cover was faulty from the get go. When I called them on mine they said I needed to send them proof of purchase. I told them I would have to find it and
would call them back. They called me back a few minutes later and told me not worry with the proof of purchase and sent me another remote with a different
configuration for the bad part. I think I had to send the old one back. It's been several years ago. They know it was a faulty design. Mine was out of warranty.
