Caution: Leaving children in a vehicle with the ignition key is dangerous for many reasons, children or others could be badly injured or even killed. They could operate the power windows or other controls or even make the vehicle move. The windows will function with the keys in the ignition and children could be seriously injured or killed if caught in the path of a closing window. Do not leave the keys in a vehicle with children.

One key works all of the lock cylinders on the vehicle.

Your vehicle has an Immobilizer Vehicle Theft-Deterrent System. The key has a transponder in the key head that matches a decoder in the vehicle's steering column. If a replacement key or any additional key is needed, you must purchase it from your dealer. The key will have PK3+ stamped on it. Keep the bar code tag that came with the original keys. Give this tag to your dealer if you need a new key made.

Notice: If you ever lock your keys in the vehicle, you may have to damage the vehicle to get in. Be sure you have spare keys.
