Key Identification and Usage
WARNING: This page is about a different car, the 2004 Buick Regal and 2004 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.
A single key is used for all of the locks on the vehicle. The key identification is obtained from the five-character key code located on the key tag. The five-character key code should be recorded by the owner and the dealer. The mechanical key code can be determined through the use of a code cross-reference list which is available to owners of key cutting equipment from the equipment suppliers.
