This chip transmits a code to the car's immobilizer device that can be integrated into the PCM, BCM, instrument cluster, smart junction box or standalone module. The system examines the code to ensure that it is correct. If the code is incorrect, the system disables components that are crucial to starting the car, such as the ignition or starter motor.

In cars manufactured after 1995, a small electronic chip, referred to as a transponder is built into the head of your car key. It is also referred to as a "chip key" or a "transmitter-responder" key. Its function is to prevent your engine from starting when someone else has the same key. It works by transmitting radio signals from the key to your immobiliser. If the code stored in the car's computer is in line with the signal sent from the key, it will disable the immobiliser and allow the engine to start.
The key that is equipped with a transponder chip is often referred to as a 'fob' or a "smart" key because it is more difficult to copy than a traditional mechanical key. It is possible to duplicate a standard key, but not a transponder key. In contrast to the remote central locking element of a conventional key, which is powered by batteries, a transponder chip is powered by an infrared (IR) signal that is transmitted through the antenna ring on the ignition cylinder.
To activate the transponder the ignition cylinder needs to be in the ON position. The ring emits a blast of IR energy, which is picked up by the microchip within the key. The chip then sends an unique code to the immobiliser inside your car. The car's computer compares the code stored in its memory with the transponder's and when the two codes match it will begin the engine.
The immobiliser will disable the engine when it detects an unauthorized key or transponder. It will also prevent any vital components of the car from functioning.

This will reset the system and allow it to accept your key once more.
The security light is an immobiliser's way of warning you of an issue.

However, this is extremely risky and requires a great deal of experience to accomplish it without cutting yourself. Additionally, many modern car thieves have shifted to more sophisticated methods, such as using specialized apps or Bluetooth to take over a car's data and remotely control it from their mobile.
