Nuts, I don't ride at night either. Too many drunks and hoofed rats for my tastes. I go home at night or put up my tent or hammock and go to sleep. I'd love to live up the stereotype, but my wife would miss me. She says she would, anyway.
So, I'm stuck with the problem of carrying at least four keys and, sometimes, more. I tried a leather case my locksmith recommended, but after only a week the lame ball-end swivel popped out of the case, dropping all of my keys in the parking lot (lucky for me). I tossed that piece of crap into the trash and went back to looking.
During a shopping expedition to REI (looking for something to cover my video camera on the bike), I was prowling the luggage and travel gear area when I spotted REI's Luggage Tag. At $3.50, it's probably the world's most expensive luggage tag, but with a little modification, it made a terrific, secure, abrasion-free motorcycle key case. Just add an ordinary metal key ring (twenty-five cents at my local hardware store) and you have a nice looking, practical key case. There is even a window for storing your business or address card, in case you lose the case and someone honorable finds it and wants to return it (fat chance, I know).
The "luggage case" has a large hook-and-loop closure that allows you to really snug the unused keys into place, so they won't slip out and gouge up your console or handlebars. I'll admit that it's a little bit larger than ideal, but it's the best I've found for the purpose. And on the Geezer's Night Out, it saves me the trouble of buying a cucumber for that "big man on the prowl" look.
