FWIW I now carry my X5 key on a carabiner style key ring and hang it from a belt loop. Because in the last 8+ years I have locked, unlocked, opened the rear hatch and rolled down all the windows on our old E53 X5 completely by accident when the key was in my pocket.

I'm not saying that is what happened, just that it is possible to do by accident while walking away from an X5.
