Electronic immobilizer
The engine immobilizer is an essential security feature that helps protect against theft of cars by ensuring that only the correct key is used to start the car.

This method has been in use for more than 20 years and it has greatly reduced the number of stolen vehicles. This system is also a reliable method to stop hotwiring. Hotwiring is the act of bypassing ignition switches by connecting wires from the ignition coil to the fuel pump relay.
