This system has been in operation for more than 20 years and has helped to decrease the theft of vehicles. It is also an effective way to avoid hotwiring. Hotwiring is the process of bypassing ignition switches by connecting wires from the ignition coil to the fuel pump relay.

The immobilizer is part of the key fob or key which contains a transponder chip. The chip transmits a passcode to the immobilizer unit of the car that is integrated into the PCM, BCM, instrument cluster or smart junction box or any other module. The immobilizer device then validates the passcode and allows the engine to start if it is valid.

Modern keys and transponder chips utilize a cryptographic algorithm in order to ensure that the code is only transmitted once and only to the authorized key fob or key. These cryptographic algorithms are designed to be difficult for hackers to crack. This technology also guards against key duplicates that are remote, which is a common instance of stolen vehicles.
