How to program your key fob
This key fob can't be programmed with a do-it-yourself procedure. The vehicle needs a diagnostic tool connected to its OBD port to pair a new fob, so a replacement has to be set up by an automotive locksmith or a dealer.
Order the correct replacement fob below — match the FCC ID on your current fob first — then have a local automotive locksmith or the dealer program it to your vehicle.
Replacement key fobs
Find your key type below, then match the FCC ID printed on the back of your existing fob — or, for a plain transponder key, the blank code — to be sure of the right part.

Order the correct replacement remote below — match the FCC ID on your current fob first — then have a local automotive locksmith or the dealer program it to your vehicle.

- 2 Twist a coin or small flathead in the slot to split the case open.
- 3 Remove the old coin cell and note the + side.
- 4 Fit the new battery with the + side matching, then close the case.

Battery tips
- Use a fresh, name-brand 3V lithium cell — bargain cells drain quickly.
