2002 Buick LeSabre Owner's Manual - Page 68

There is a master key that works in all of the lock cylinders (driver's door, trunk, ignition, 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. There is also a VALET key which only operates the driver's door and the ignition. 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" 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
