The chip transmits a passcode to the immobilizer unit of the car which can be integrated into the PCM, BCM or instrument cluster smart junction box, or standalone module.

Transponder Chip
A tiny electronic chip, referred to as a transponder, is built inside the head portion of your car keys. This technology was introduced in cars made after 1995. It is also referred to as a "chip key" or a "transmitter-responder" key. Its goal is to stop your engine from starting when someone else has a duplicate of your key. It functions by sending the radio frequency signal from the key to the immobiliser system in your car. If the code stored in the computer of the car is in line with the signal sent by the key the immobiliser will then be deactivated and the engine will be able to start.
The key with the transponder is also called a "fob" or a "smart" key, because it is more difficult to duplicate than a mechanical key. Using specific techniques, it is feasible to copy a standard car key but not transponder keys. In contrast to the remote central locking element of a standard key that relies on battery power, a transponder chip is powered by an infrared (IR) signal transmitted by the antenna ring on the ignition cylinder.
To activate the transponder chip the ignition cylinder needs to be switched to ON. The ring emits IR energy that is picked up by a microchip within the key. The chip responds with an individual code to the immobiliser inside your car. The computer in the car compares the code stored in its memory to the transponder's and when the two codes match it will start the engine.
If the immobiliser detects that an unauthorised transponder or key is in use it will shut down the engine and more info prevent any of its essential components from functioning.

If the system can't identify a digital serial number from the chip inside your key, it will disable the engine immobiliser and prevent the car from getting started.
The car immobiliser system is an effective in stopping thieves, but it is also possible for it to be out of sync with the key or transponder chip. This can be caused by interference or the system being too sensitive. If this is the case, it may need to be reset. To do this, simply disconnect the battery. It should be left disconnected for around 15 minutes, then insert it and begin the vehicle. This will reset the key system so that it is ready to accept your keys once again.
The security light is the car immobiliser's way of telling you that there's a problem with the system. If the light is on when you try to start your vehicle, it indicates that the code that is more info stored in the ECU does not match the chip inside the key. This could happen in the event that your car's key has been replaced by a new one that is not compatible with the vehicle, or if the ECU has been swapped incorrectly.
If this is the case, then it's time to go to a professional to have the key or the transponder chip properly programmed to your vehicle.

Modern cars are equipped with this security system as standard. This makes it extremely difficult to wire the car hot or use a different key for starter. The system works by checking the chip in a key fob or key and sending a passcode back to the ECU (electronic read more control unit). The ECU knows it's the correct key and that there hasn't been compromised code. The system will not allow the car to start in the event that it does not receive the correct code. Some models even notify the owner if they try to use an unapproved fob or key.
The system isn't impervious to attack, but it is. Some thieves have bypassed the immobiliser with techniques such as 'hot-wiring.' This involves crossing the wrong wires within the wiring of a vehicle to trick the ECU to believe that the proper key or fob is being used. However, this method is pretty risky and requires a lot of experience in order to do it without damaging yourself. Additionally, many modern car thieves have moved over to more advanced methods like using specialized apps or Bluetooth to take over a car's data and remotely control it from their phones.
Car owners will frequently see warning lights that indicate an immobiliser malfunctioning. This can happen for various reasons, but the most common is website a faulty or dead battery in the key fob. This issue can be resolved by replacing the battery.
