1996 Buick LeSabre Owner's Manual - Page 58

The ignition keys are for theignition only. When a new LeSabre is delivered, the dealer removes the plugs from the keys, and gives them to the first owner. However, the ignition key may not have a plug. If the ignition key doesn't have a plug, it will have a bar-coded key tag. Each plug or tag has a code on it that tells your dealer or a qualified locksmith how to make extra keys. Keep the plugs or the tags in a safeplace. If you lose your keys, you'll be able tohave new ones made easily using these plugs or the tag. If your ignition keys don't have plugs or the tag, 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. I NOTICE: Your Buick has a number of features that can help prevent theft. But you can have lot of trouble a 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. 2-2
