I used to have a hide-a-key, then I went 4 wheeling without warning one day. never saw it again..it was inside the frame as well. I figured some brush or palmettoes got up in there and swept it out somehow as I went chasing down a (sorta)dirt trail. That's when I decided to epoxy on to the top of the frame, above the spare tire area..remarkably after that, I never lost my keys. go figure.
