...I carry two fobs and use both belt and suspenders (yeah, I know, expensive, but I always ask of a bike's components, what could possibly go wrong?). And I'm with Lee. Battery change about every 17,000 miles (along with a new headlight bulb - as now-a-days, they seem to have a very predictable life span of ~300+ h).
One fob's zippered into the pants; one fob's zippered into the coat with the back-up wallet and emergency key.. The simple, non-electric key for luggage generally stays in the seat lock, so I don't have to look for it.
Of course, one of us avoids all worry, and simply leaves his key in the tank bag.
No muss, no fuss.
Never lost.
Never left behind.
Never falls out of a pocket.
