My spare fob (with battery installed backwards) is in my toiletries bag, and my spare key is taped to a hidden area that requires no tool to access. Instructions for starting the bike without fob are in my wallet, in my tourpak,
and to the bottom of my seat!! Also, practice starting the bike with the security bypass procedure every once in a while. You will not be able to do it when your fob fails and you are mad.
