The key fob battery powers the remote locking and opening systems. However, it does not supply power to the immobiliser.

This chip transmits a code to the immobilizer unit of the car, which may be built into the PCM, BCM, instrument cluster smart junction box or standalone module. The system examines the code to ensure that it is correct. If it is not, the system will disable components crucial to starting the vehicle, like the ignition or starter motor.

Transponder Chip
A small electronic chip, called a transponder, is built into the head portion of your car keys. This technology was introduced in vehicles manufactured after 1995. It is also referred to a "chip key" or a "transmitter-responder" key. Its purpose is to prevent your engine from starting when another person has an identical key. It works by transmitting an audio frequency signal from the key to the immobiliser system inside your car. If the code stored in the car's computer matches the signal transmitted by the key the immobiliser will be deactivated and the engine will be able to start.
The key with the transponder is also referred to as a "fob" or a "smart" key due to the fact that it is more difficult to duplicate than a mechanical key. Utilizing specific methods, it is possible to copy a standard car key however, not the transponder key. Transponder chips are powered by an infrared signal, not battery power.
To activate the transponder chip, the ignition cylinder has to be turned to the ON position. The ring emits a burst of IR energy, which is absorbed by the microchip within the key. The chip responds by sending a unique code the immobiliser of your car. The car's computer compared the code stored in its memory with the one from the transponder chip, and If they are compatible the engine will begin to rev.

It is an anti-theft device that blocks anyone from driving your vehicle without the correct key. If the system cannot detect a digital serial from the chip on your key, it will shut off the engine immobiliser to prevent the car starting.
The car immobiliser is an excellent method of deterring thieves, but it could sometimes get out of in sync. This could be due interference or the system is too sensitive. If this is the case it might need to be reset. To do this, disconnect the battery. Then leave it off for around 15 minutes, then insert it and start the vehicle. This will reset the system and make it ready to accept the key again.
The security light is an immobiliser's method of alerting you to an issue. If you try to start the car but the light stays on it indicates that the chip inside your key isn't compatible with the code that is stored in the ECU. This can happen if you have recently replaced your car key with one that was not programmed to the vehicle or in the event that you've had a defective swapped ECU.

The immobiliser will be disengaged when it is unable to recognize the code. That's why it's so difficult to defeat.
Modern cars have this system as standard. This makes it very difficult to connect the car to a hot wire or use another key for starter.

The system will not allow the car to start if it does not receive the correct code. Certain models will even notify the owner if they attempt to use an incorrect fob or key.
However the system isn't completely secure. Some thieves have been able to get around the immobiliser using methods like hot-wiring. This involves crossing the wrong wires in a vehicle's wiring to fool the ECU into thinking the correct key or fob is being used. However, this is pretty risky and requires a great deal of experience to accomplish it without electrocuting yourself. Modern car thieves are using more advanced methods, for instance, Bluetooth or specialised apps to take over a car's data and remotely manage it remotely.
