If the key is valid, the engine will start. If the key is invalid, the engine will not start.
To deactivate the immobilizer system: Insert the ignition key into the key cylinder and turn it to the ON position.
To activate the immobilizer system:
Turn the ignition key to the OFF position. The immobilizer system activates automatically. Without a valid ignition key for your vehicle, the engine will not start.
