The same explanation works for why you don't feel a "shock" from
static electricity if you hold a metal object in your hand and touch
something that is grounded. The "shock" is actually local heating of
your skin caused by a relatively high current density at the point
where you skin is close to the grounded object. If you hold a metal
object, like your car key, creates a large area of contact and hence
a low current density, and no sensation of shock.
