What car keys have chips in them?

Answer 1

Transponder Keys - have a chip inside the handle of the key, which also often features remote control buttons for locks & trunk access. "Remote keys" and "switchblade keys" are two types of transponder keys.

Smart Keys/ FOBIK Keys - an all-in-one car remote & key, usually standard with push-button start & "keyless entry" cars

VATS Keys - for older model GM vehicles have been called "chip keys" because of the resistor on the key blade. The resistor looks like a "chip," but in fact is not a computer chip at all.
