It works by sending a radio frequency from the key to your immobiliser. If the code on the car's computer matches the signal from the key, it will disarm the immobiliser and allow the engine to start.
The key that has the transponder chip is sometimes called a 'fob' or a 'smart' key due to the fact that it is more difficult to copy than a conventional mechanical key. Utilizing specific techniques, it is feasible to copy a conventional car key however, not transponder keys. Transponder chips are powered by an infrared signal and not battery power.
To activate the transponder chip, the ignition cylinder needs to be turned on. The ring emits a blast of IR energy that is picked up by the microchip in the key. The chip responds by sending a unique code to your car's immobiliser. The car's computer analyzes the code stored in its memory to the transponder's and if the two codes match it will start the engine.
The immobiliser shuts down the engine in the event of an unauthorized key or transponder. It also stops any vital components of the car from functioning.

The security light is a way of alerting you to an issue. If the light is on when you attempt to start your car, it means that the code stored in the ECU is not compatible with the chip inside the key. This can happen if you have remote key repairs recently replaced the car key with a different one that was not programmed to the vehicle or when you've had a damaged swapped ECU.

Some models even notify the owner if they try to use an incorrect fob or key.
However, the system is not foolproof. Certain thieves have been able to get around the immobiliser using methods such as 'hot-wiring'. This involves crossing the wrong wires in the wiring of a vehicle to trick the ECU into thinking the appropriate fob or key is being used. But, this technique is extremely dangerous and requires a lot of knowledge of how to accomplish it without cutting yourself. Modern car thieves are employing more sophisticated methods, like Bluetooth or other apps that take over a car's data and remotely manage it remotely.
