1. Two working keys for your vehicle.
2. Access to the vehicle's diagnostic port, which is usually located under the dashboard.
3. A diagnostic scanner that is compatible with your vehicle.
Once you have gathered these items, follow these steps to reset the key code immobilizer:
1. Connect the diagnostic scanner to the vehicle's diagnostic port.
2. Turn the ignition key to the "ON" position, but do not start the engine.
3. Select the "Engine" or "Immobilizer" option on the diagnostic scanner.
4. Follow the prompts on the diagnostic scanner to reset the key code immobilizer.
5. Once the key code immobilizer has been reset, turn the ignition key to the "OFF" position.
6. Remove the diagnostic scanner from the vehicle's diagnostic port.
7. Start the engine using one of the working keys.
If you do not have two working keys for your vehicle, you will need to have a new key programmed by a qualified automotive technician.
