I have a question for you: why does Hertz give me two car keys on the same ring? These are not thin keys, but the ones with the big, black plastic “handle” on them. The resulting mass of keys, remote, and key ring is too big to comfortably fit in my pocket. It’s not as though I can remove one of the keys; the ring is permanently joined.

Update: A coworker suggested that, because these keys have a chip in them that must operate correctly for the car to start, Hertz may be providing redundant protection should a chip fail.
