1999 Chevrolet Monte Carlo Owner's Manual - Page 65

yellowblue This key is for the ignition only. The ignition keys don't have plugs. Your dealer or Chevrolet Roadside Assistance has the code for your keys. The door keys do have plugs. The plug has a code on it that tells your dealer or a qualified locksmith how to make extra door keys. Keep the plugs in a safe place. If you lose your door keys, you'll be able to have new ones made easily using these plugs. If you need a new ignition key, contact your dealer who can obtain the correct key code, or, in an emergency, call Chevrolet Roadside Assistance at 1-800-CHEV-USA R (1-800-243-8872). In Canada, call 1-800-268-6800. This key is for the doors and all other locks. NOTICE: Your vehicle has a number of new 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. When a new vehicle is delivered, the dealer removes the plugs from the door keys and gives them to the first owner. 2-3
