Just got my BRAND NEW RioCar and the remote worked for exactly 3 days before dying. Occasional intermittent operation for about a half day, then died.
Replaced the battery (CR2025) from the drug store for $3 and it worked immediately. Probably get it a Wal-Mart for half that...
My unit was made in April of 2001 and it was installed in February of 2002, so they obviously go bad on the shelf. Who knows when the remote was made... obviously a LONG time ago!
Just try a new battery.
