GM Service Manual Online
For 1990-2009 cars only

This vehicle has a passive theft-deterrent system.

The system is automatically armed when the key is removed from the ignition.

The system is disarmed when the key is turned to ON/RUN.

You do not have to manually arm or disarm the system.

The key uses a transponder that matches an immobilizer control unit in the vehicle and automatically disarms the system. Only the correct key starts the vehicle. The vehicle may not start if the key is damaged.

If the vehicle does not start:

    • Make sure the fold away key is fully extended.
    • Avoid attaching several keys with the ignition key.
    • Avoid attaching keys from other vehicles to the ignition key.
    • Do not attempt to start the vehicle with a non-approved key.
    • Do not disassemble the key.

When trying to start the vehicle, if the engine does not start, the key may have a damaged transponder. Turn the ignition off and try again.

If the engine still does not start, and the key appears to be undamaged, try another ignition key.

If the engine still does not start, the vehicle needs service. See your dealer/retailer to service the theft-deterrent system and have a new key made.

The following procedure is for programming additional keys only. If all vehicle keys are lost or no longer work, see your dealer/retailer. A new key must be made prior to programming.

A maximum of four keys can be programmed for the vehicle.

  2. If the engine does not start, see your dealer/retailer.

  3. Remove the key from the ignition.
  4. Insert and turn the new section (A) to ON/RUN within five seconds of removing the original key.
  5. Turn the new section (A) to LOCK/OFF. Section (A) is now programmed.

  1. Turn the ignition to ON/RUN with the new section (A).
  2. The vehicle must be in P (Park).

  4. Select Program.
  5. Press and on the new section (B), at the same time, until you hear two beeps.
  6. Repeat Step 4 for all other keys, including keys that require programming or ones previously programmed to the vehicle. Any key not reprogrammed will be erased.
  7. Turn the ignition to LOCK/OFF.
  8. Join sections (A) and (B) until they click.
  9. Do not join the two key sections until programming is complete.
