yellowblue The master key is used for the ignition, as well as all door locks and storage compartments. When a new vehicle is delivered, the dealer removes the bar-coded key tags from the keys, and gives them to the first owner. Each tag has a code on it that tells your dealer or a qualified locksmith how to make extra keys. Keep the tags in a safe place. If you lose your keys, you'll be able to have new ones made easily using the tag. If you misplace your tag, go to your dealer for the correct key code if you need a new ignition key. NOTICE: The valet key is used for the ignition and the two side doors only. It will not open the trunk or glove box. This is a theft-deterrent feature. The valet key should always be used when valet parking your vehicle. Your vehicle has a number of features that can help prevent theft. But 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 extra keys. 2-3
