1. Locate the immobilizer box. It's usually located under the dashboard, near the steering column.
2. Remove the immobilizer box. There are usually two screws that hold it in place.
3. Cut the wires leading to the immobilizer box. There are two wires, one black and one green.
4. Connect the black wire to ground.
5. Connect the green wire to the ignition switch.
6. Reinstall the immobilizer box.
7. Start the engine. The immobilizer will be bypassed, and the car will start.
Note: This is a temporary solution. You will need to have the immobilizer repaired or replaced as soon as possible.
