Before you buy

Must be programmed to your vehicle

This key isn’t plug-and-play. It has to be programmed to your car before it starts the engine or works the buttons.

Emergency key included — it comes uncut

The metal emergency key inside the fob ships blank and needs cutting to your vehicle.

Match your key before you order

The part number and FCC ID must match your current key, and so must the number of buttons. If a frequency is printed on your key, check that too. Keys can look identical and share an FCC ID but still be different parts. Lost every key? Your dealer can give you the part number from your VIN.

Some dealers won’t program aftermarket keys

An automotive locksmith can.
