Electronic immobilizer
The engine immobilizer is a crucial security feature that helps prevent car theft by ensuring that only the right key is used to start the vehicle.

This system has been around for more than 20 years and it has drastically reduced the rate of vehicle theft. It is also an effective way to avoid hotwiring. Hotwiring is the act of bypassing ignition switches by connecting wires from the ignition coil to the fuel pump relay.
