One key is used for the ignition and all other locks. Each tag has a key code on it that tells your dealer or a qualified locksmith how to make extra keys. Keep the tag in a safe place. If you lose your keys, you'll be able to have one made easily using this tag. If you need a new key, go to your dealer for the correct key code. See Roadside Assistance Program on page 7-5 for more information. 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 keys inside. You may even have to damage your vehicle to get in. So be sure you have spare keys. When a new vehicle is delivered, the key has a bar-coded key tag. This tag may be removed by your dealer before it is delivered. 2-3
