2004 Chevrolet Aveo Owner's Manual - Page 69

One key is used for the ignition, the door and all other locks. When a new vehicle is delivered, the dealer removes the key tag and gives it to the first owner. The tag has a code on it that tells your dealer how to make extra keys. For vehicle security, keep the key tag in a safe place and also record the key number somewhere other than inside of the vehicle. If you lose your key, you will be able to have a new one made easily using the tag. Your vehicle may have an electronic immobilizer designed to protect your car against theft. If so, only keys with the correct electronic code can be used to start the vehicle. Even if a key has the same profile, it will not start the engine if the electronic code is incorrect. If you need a new key, contact your dealer who can obtain the correct key code. See Roadside Assistance Program on page 7-6 for more information. Notice: If you ever lock your keys in your vehicle, you may have to damage the vehicle to get in. Be sure you have spare keys. 2-3
