1996 Buick Park Avenue Owner's Manual - Page 58

The ignition keys are for the ignition only. When a new Park Avenue is delivered, the dealer removes the plugsfrom the keys, and gives themto the first owner. However, if the ignition key does not have a plug, there may be a bar-coded key tag instead. Each plug has a code on it that tells yourdealer or a qualified locksmith howto make extra keys. Keep the plugs in a safe place. If you lose your keys, you'll be able to have new ones made easily using these plugsor the tag. If your ignition keys don't have plugs, go to your Buick dealer for the correct key code if you need a new ignition key. The door keys are for the doors and all other locks. NOTICE: Your Buick has a number of features that can help prevent theft. But you can have lot of a trouble getting into your vehicle if you ever lock your keys inside.You may even have damage to your vehicleto get in. So be sure you have extra keys.
