2002 Buick Park Avenue Owner's Manual - Page 68

The master key is used for the ignition, as well as the driver's door lock, trunk and glove box. 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 steering column. 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-KeyR III" in the Index for more information on programming your new key. The VALET key is used for the ignition and the driver's door 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. If your vehicle is equipped with the OnStarR System with an active subscription and you lock your keys inside the vehicle, OnStar may be able to send a command to unlock your vehicle. See "OnStarR System" in the Index for more information. NOTICE: 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. 2-5
