This bulletin is being published to reflect changes to the Radio Codes section. Please discard Corporate Bulletin Number 04-00-89-007D (Section 00 - General Information).
In certain circumstances, the technician will need to have the radio, key or immobilizer codes. The Chevrolet Epica may have radio, key and immobilizer codes while the Chevrolet Aveo and Optra may have radio and key codes but do not require an immobilizer code. The Pontiac Wave has key codes only and does not require radio or immobilizer codes.
Radio Codes
Important: The radio security code feature was eliminated during the 2004 model year. Please see the table below for VIN breakpoint information.
Important: Any time an exchange or replacement radio is installed in the vehicle and requires a new radio code, the new four-digit radio security code must be recorded on the customer and shop copies of the repair order and also on the glovebox index card (if available) for future reference.
Important: U.S. Dealers MUST call GM TAC in order to obtain the radio codes if they are not readily available in the glovebox index card. Canadian dealers MUST call GM of Canada Dealer Technology at 905-644-4827.
If the vehicle was built AFTER the VIN breakpoint listed in this table, it does NOT have a radio security code.

Key Codes
For the Chevrolet Aveo, Optra and Pontiac Wave, the five-digit key code is stamped on a tag that is supplied with the vehicle keys.
For the Chevrolet Epica, the five-digit key code is also stamped on a tag that is supplied with the vehicle keys. The code is 12 digits long. The actual key code is extracted by using digits 1-5.
Immobilizer Codes
For the Chevrolet Epica, the six-digit immobilizer code is stamped on a tag that is supplied with the vehicle keys. The code is 12 digits long. The actual immobilizer code is extracted by using digits 6-11.
Important: There is only one code stamped on the tag. Digits 1-5 are the key code and digits 6-11 are the immobilizer code. Digit 12 is a "dummy" number.
Code Retrieval Process -- US Dealers
Important:
• The code look up feature is located in DealerWorld under the Parts tab and is only visible to personnel with the necessary profile credentials (typically the Parts Manager). See your dealer's Partner Security Coordinator. • Not all VINs prior to the breakpoints listed above will display a radio code. If you cannot locate a code, please contact the U.S. Technical Assistance Center (TAC) at 1-877-446-8227. You will need to supply the radio's serial number in order for
the TAC consultant to locate the correct code. • The immobilizer codes for the Chevrolet Epica are NOT in DealerWorld. U.S. Dealers should contact GM of Canada's Dealer Technology at 905-644-4827 for these codes. • U.S. Dealers should only contact GM of Canada's Dealer Technology for issues concerning the Chevrolet Optra, Epica and Pontiac Wave.
