To scratch the paint job on a car with a set of keys.

One holds the heads of the keys between fingers-- pointy toothed bits out, fob and lucky charms in the palm of your hand-- and swipe at the surface of the car like you are the comic book character Wolverine.

In basketball, the key is the lane area plus the half-circle above the free throw line. It's kinda shaped like a key hole.

Guarding this position is a big part of why zone defense is so much better than man-to-man.
