Transponder Chip
In cars manufactured after 1995, a small electronic chip referred to transponder is integrated into the head of your car key.

It works by sending the radio frequency signal from the key to the immobiliser system of your car. If the code stored in the car's computer matches that signal transmitted by the key, it will disarm the immobiliser and allow the engine to start.
The key that is equipped with a transponder chip can be referred to as"fob" or a 'smart' key because it is much more difficult to clone than a conventional mechanical key. With the help of specific techniques, it is feasible to duplicate a standard car key, but not a 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 on. The ring emits a burst of IR energy, which is absorbed by the microchip within the key. keys repair responds by sending a unique code the immobiliser of your car. The car's computer compares the code stored in its memory with that from the transponder chip, and If they are compatible the engine will be able to start.
The immobiliser will disable the engine in the event of an unauthorized key or transponder. It will also prevent any essential parts of the car from functioning. The car won't move when the engine isn't functioning. It would be easy for criminals to wire it and then drive off.

Security Light
The immobiliser is powered by a small battery that transmits an electrical signal to the transponder chip in your key. It is an anti-theft device that blocks anyone from opening your car without the correct key. If the system is not able to recognize a digital serial from the chip in your key, it will disable the engine immobiliser to prevent the car from starting.
The car immobiliser is an excellent method of deterring thieves, but it can occasionally be out of sync. This could be due to interference or an immobiliser that is too sensitive. This could require an adjustment. To do this, just disconnect the battery. Leave it disconnected for about 15 minutes before reinstalling it and start the vehicle. This will reset the system and allow it to accept your key once more.
The security light is the car immobiliser's way of telling you that there's an issue with the system. If you attempt to start your car and the light stays on, it means that the chip in your key doesn't match the code stored in the ECU. This could happen if your car key has been replaced with a new one that is not compatible with the vehicle, or if the ECU was not swapped correctly.
If this is the situation it is recommended to take your key or transponder chip to a professional for them correctly programmed for the vehicle you are driving. It is possible that the system isn't able to accept the key due to a software upgrade or bug.

Programming
An immobiliser for cars prevents the car's engine from operating without a correctly programmed key or fob.

This is why it's so hard to defeat.
Modern cars come with this security system by default. This makes it extremely difficult to wire the car hot or use another key for starter. The system works by checking the chip inside a key fob or key and transmitting a passcode to the ECU (electronic control unit). The ECU will then verify that it's the correct key and that the code isn't compromised. The system won't allow the car to start if it does not receive the correct code. Some models even inform the owner if they try to use an incorrect fob or key.
However the system isn't completely secure. Some thieves have managed to bypass the immobiliser by using methods such as 'hot-wiring'. This involves crossing the wrong wiring in a vehicle to cause a malfunction in the ECU. This method is risky and requires extensive knowledge to avoid electrocuting oneself. Plus, a lot of modern car thieves have shifted to more sophisticated methods like using specialized apps or Bluetooth to hijack the car's data and then remotely control it from their phones.
Car owners are often faced with warning lights that indicate the immobiliser has gone haywire. This can occur for various reasons, but the most common reason is a defective battery in the keyfob. This issue can be resolved by replacing the battery.
