$68, comes with 2 keys and easy to change (and subsequently alarming just how easy it would be to drive off with one of these just by buying one).
I don't like loading up the parts cannon and have the tools and knowledge to document the issue if it occurred enough to do so, but mine was so erratic it would have been impractical to do so. So I used an "educated guess" and it appears I got it.
This switch, and the ground wires on the frame behind the gas tank are big causes, along with loose battery cables. Clean/tighten them and do the switch and stop wasting money on a dealer who doesn't give a damn.
If you truly can't or won't do it yourself, I'd Suggest you contact @HondaTech and make arrangements for a road trip.
