The chip transmits a code from the key or fob to the immobilizer unit of the car, which can be integrated into the PCM (power control module) BCM (brake control module), instrument cluster, smart junction boxes, or standalone modules.

Transponder Chip
In vehicles manufactured after 1995, a tiny electronic chip called transponder is integrated into the head of your car key. Also known as a chip key or a 'transmitter and responder key, it's designed to stop the engine from starting if another person has a copy of your car key. It functions by sending an audio frequency signal from the key to the immobiliser system inside your car. If the code stored in the car's computer is in line with the signal sent by the key the immobiliser will then be removed and the engine will begin to run.
The key with the transponder chip is sometimes called a 'fob' or a smart key because it is much more difficult to clone than a traditional mechanical key. It is possible to duplicate a conventional key, but not a transponder one. Transponder chips are powered by an infrared signal not battery power.
To activate the transponder chip, the ignition cylinder needs to be turned on. The ring emits a flash of IR energy, which is picked up by the microchip in the key. The chip responds by sending a unique code to the immobiliser of your car. The car's computer checks the code stored in its memory with that from the transponder chip, and when they match, the more info engine will start.
If the immobiliser detects an unauthorised transponder, key or other device is in use, it will disable the engine and prevent any of its essential components from working. Without a functioning engine the car will not be able to move, and it could get more info be easy for criminals to wire the vehicle and drive away.

Security Light

This is an anti theft device that stops anyone from driving your vehicle without the correct key. If the system cannot detect a digital click here serial number from the chip in your key, it will deactivate the engine immobiliser and stop the car from getting started.
The car immobiliser is a great method to deter thieves, but it could sometimes be out of the sync. This could be due to interference or the system becoming too sensitive. If this is the case, it may need to be reset. To do this, simply disconnect the battery. Then leave it off for around 15 minutes then reinsert it and begin the car. This will reset the system and make it ready to accept your key once more.
The security light is the car immobiliser's way of telling you that there is an issue with the system. If the light is on when you try to start your car, it means that the code stored in the ECU does not match the chip inside the key. This could happen if you have recently replaced the car key with a different one that isn't programmed to your vehicle or in the event that you've had a defective swapped ECU.
If this is the situation you should bring your transponder key or chip to a professional to get them correctly programmed for the vehicle you are driving.

That's why it's so difficult to defeat.
Modern cars come with this system as standard. This makes it extremely difficult to hot-wire a vehicle or utilize a different key for starter. The system works by sending a code more info from the key fob to the ECU. The ECU then knows that it's the right key and that the passcode hasn't been compromised. The system won't allow the car to start if the doesn't receive the correct code, and some models will even inform the owner if someone tries to use an unapproved fob or key.
However the system isn't completely secure. Some thieves have bypassed the immobiliser with techniques such as 'hot wiring.' This involves crossing the wrong wires through the wiring of a vehicle, which fools the ECU into thinking the proper key or fob is being used. This is a risky method and requires extensive expertise to avoid electrocuting yourself. Additionally, many modern car thieves have shifted over to more advanced methods like using specialized apps or Bluetooth to take over the car's data and then remotely control it via their phones.
Car owners often see warning lights that signal that the immobiliser has gone off the rails. This could be due to a variety of reasons, but the most common is a faulty or dead battery on the key fob. A simple replacement should fix this issue.
If this does not work it could be because the transponder chip is defective or the ECU is not matched. This is more difficult to fix and diagnose, as it can involve an expert locksmith for cars or a dealership.
