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 vehicle. This is accomplished by using the code on the car's key with the one stored in a computer. The engine will only start only if the codes match. This method has been in use for more than 20 years and it has drastically reduced the number of stolen vehicles. It is also a great way to prevent hotwiring. Hotwiring is the act of bypassing ignition switches by connecting wires from the ignition coil to the fuel pump relay.
The immobilizer is a part of the key fob or key that contains a transponder chip. The chip transmits a passcode from the key fob or key to the immobilizer system of the vehicle and is integrated into the PCM (or BCM), instrument cluster and smart junction boxes or other modules. The immobilizer unit validates the code and permits engine start if the passcode is valid.

Another option is to use a device to change the code of the key or transponder chip. This can be accomplished by using a tool called"transponder reader" or "transponder reader," which is available online for purchase. These tools do not always work however they can be useful in some cases.
