Piece of Paracord tied to the FOB and cylinder key. Long enough to form a loop that wraps around my belt and both tuck into my watch pocket of my jeans. If not then it is in a zippered pocket in my clothing. I rarely lock the switch but sometimes I do, along with everything else. (I have extra FOB batteries and Security unlocking procedures on my phone.)
I have the HD saddle bag organizers with the pockets,There is a Hook on them an I hook my Fob to that,An I always carry a brand new battery for the Fob in case mine has a problem,For a $1.99 its worth haveing a spare an I put a new battery in every spring.
