Not sure which kind of key you have? Knowing the type tells you whether it needs programming and roughly what a replacement involves.

The Main Types

There are four common kinds: a basic metal key, a transponder key (a chip inside a plastic head), a remote head key (transponder plus buttons), and a smart or proximity key for push-to-start cars. The last three all need programming to your vehicle.

How To Tell Which You Have

A plain metal key with no plastic or buttons is usually non-transponder. A chunky plastic head, buttons on the key, or a push-start button on the dash all point to electronics that need pairing.
