I was guilty of this. For me, I hate stuff in my pockets moving around while I’m riding. It drives me crazy and distracts me. I also have this weird fear that I’m gonna crash and jab my key into my hip. I actually had a friend who crashed with his key fob and it destroyed his hip. Deep bruises for weeks, it was nasty, his entire leg was black n blue. For the longest time I rode with a pack and dropped it inside the pack but a couple years ago when I started feeling like I wanted to start riding lighter and ditched the pack I needed a place for my key. The tire it went. It always freaked me out though so I got more creative and found a cavity under my truck’s wheel well where it fit perfect and was totally discrete. Luckily I have the keypad now and, like AllGrainer, I lock them inside. Problem solved for me at least.
