Your vehicle has the PASS-KeyR III vehicle theft system. Both the master and VALET key have a transponder in the key head that matches a decoder in the vehicle's instrument panel. If a replacement key or any additional key is needed, you must purchase this key 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. Any new PASS-Key III key must be programmed before it will start your vehicle. See "PASS-Key III" in the Index for more information on programming your new key. Master Key Valet Key There is a master key that works all of the lock cylinders (driver's door, trunk, ignition and glove box). There is also a VALET key which only operates the driver's door and the ignition. NOTICE: Your vehicle has a number of new features that can help prevent theft. You can have a lot of trouble getting into your vehicle if you ever lock your key inside and you may have to damage your vehicle to get in. Be sure you have an extra key. 2-7
