Electronic immobilizer
The engine immobilizer is a crucial safety feature that helps to stop car theft by making sure that only the correct key is used to start the vehicle. This is accomplished by using the code on the car's key to the one stored in computer. If the codes match the computer, the engine is allowed to begin. This system has been in operation for over 20 years and has helped to reduce vehicle theft. It's also a great method to prevent hotwiring which is the process of bypassing the ignition switch by connecting wires between the ignition coil and the fuel pump relay.
The immobilizer is part the key fob, or key that has a transponder. The chip transmits a passcode from the key fob or key to the immobilizer system in the vehicle and is integrated into the PCM (or BCM), instrument cluster, smart junction boxes, or other modules. The immobilizer unit then verifies the passcode and allows the engine to start if it is right.

These cryptographic algorithms were developed to be hard to decode by hackers. This technology is protected against remote key replication which is a frequent occurrence when cars are stolen.
