It is also known as a "chip key" or a "transmitter-responder" key. Its goal is to stop the engine from starting when someone else has an identical key. It works by transmitting an audio signal from the key to the immobiliser system. If the code on the car's computer matches the signal sent from the key, it will disarm the immobiliser and allow the engine to begin.
The key with the transponder chip is often referred to as"fob" or a 'smart' key due to the fact that it is more difficult to clone than a traditional mechanical key. It is possible to duplicate a traditional key, but not a transponder key. Contrary to the central locking element remote of a standard key which uses battery power, a transponder chip powered by the infrared (IR) signal that is transmitted by the antenna ring on the ignition cylinder.
To activate the transponder the ignition cylinder must be in the ON position. The ring emits a burst IR energy which is detected by a microchip within the key. The chip then sends an individual code to the immobiliser inside your car. The car's computer compares the code stored in its memory with that from the transponder chip, and if they match the engine will begin to rev.

This involves crossing the wrong wire in an automobile to trick the ECU. This is a risky method and requires a lot of experience to avoid electrocuting oneself. Modern car thieves are employing more sophisticated methods, like Bluetooth or other apps that obtain information about a vehicle and remotely control it remotely.
