The key fob battery powers the remote locking and opening systems. However, it does not supply power to the immobiliser. The immobiliser is powered by a transponder located in the key, fob or instrument cluster. This chip sends a passcode to the car's immobilizer device that can be integrated into the PCM, BCM, instrument cluster smart junction box, or standalone module. The system then validates the code to make sure it is correct. If the code is not correct, the system disables elements that are crucial to the start of the car, such as the starter motor or ignition. This will make the car difficult to start without the right key.
Since its introduction the immobiliser has proved to be a very effective tool in reducing car theft. Even so, thieves are constantly trying to get around these security measures. One of these methods is the Kia Challenge trend on TikTok that shows how simple it is to wire an automobile.

Transponder Chip
A tiny electronic chip, referred to as transponder, is embedded into the head portion of your car keys. The technology was introduced in cars manufactured after 1995. It is also known as a "chip key" or a "transmitter-responder" key. Its purpose is to stop the engine from starting when you have an identical key. It works by sending a radio 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 then be disarmed and the engine will be able to start.
The key with the transponder is also referred to as a "fob" or a "smart" key, as it is more difficult to duplicate than mechanical keys. Using specific techniques, it is possible to copy a conventional car key but not transponder keys. Transponder chips are powered by an infrared signal and not battery power.
To activate the transponder, the ignition cylinder must be in the ON position. The ring emits IR energy that is detected by a microchip within the key. The chip responds by transmitting a unique code to the immobiliser of your car. The car's computer compares the code stored in its memory to the transponder's code and if the two codes match, it will start the engine.
If the immobiliser is able to detect an unauthorised transponder or key is in use it will shut down the engine and prevent the essential components from working. The car won't move when the engine isn't working. It would be easy for a criminal hot-wire it and drive off. This is a powerful security measure against crime, and is why you should have your car's key-immobiliser fixed promptly when it has a problem. If you don't fix it, the security light on your car will keep flashing and it will be impossible for you to start your engine.
Security Light
The immobiliser is powered by a tiny battery that transmits an electrical signal to the transponder chip inside your key. It is an anti-theft device that prevents anyone from driving your car without the proper key. If the system is unable to identify a digital serial number from the chip inside your key, it will disable the engine immobiliser and prevent the car from beginning.
The car immobiliser system is an an effective way to stop thieves, but it is also possible for it to be out of in sync with the key or the transponder chip. This could be due interference or the system is too sensitive. This could need the system to be reset. To do this, simply disconnect the battery. After 15 minutes, reconnect the battery and then restart the car. This will reset the key system so that it is ready to accept keys once more.
The security light is an immobiliser's method of warning you of the presence of a problem. If the light is on and you attempt to start your car, it is a sign that the code in the ECU is not compatible with the chip on the key. This can happen if you have recently replaced your car's key with another that was not programmed to the vehicle or if you've had a bad swapped ECU.
If this is the situation, then you need to go to a professional and have the transponder or key chip properly programmed to your vehicle. There is also the possibility that the system isn't accepting the key because of an update or software issue. To test this, insert your key in the ignition and turn it to the ON position. Do not attempt to start the vehicle. Keep the key in this position for 10 minutes. The security light should turn on, then turn off. If it doesn't you'll need to repeat the procedure and wait for another 10 minutes. This should solve the issue if you repeat it three times.
Programming
The car immobiliser stops the engine from running if a key or fob is not properly programmed. It uses a special RFID microchip that isn't able to be copied and has its own digital serial number. The immobiliser will be disengaged when it is unable to recognize the code. It's difficult to beat.
Modern cars are equipped with this security system in the standard configuration. This makes it very difficult to connect the car to a hot wire or use a different key for starter. The system works by analyzing the chip in a key fob or key and sending a passcode back to the ECU (electronic control unit). The ECU then knows that it's the correct key and that the code hasn't been compromised. The system won't allow the car to begin in the event that it does not receive the correct code. Certain models will even notify the owner if they attempt to use an incorrect fob or key.
The system isn't impervious to attack, but it is. Certain thieves have been able to bypass the immobiliser using methods like hot-wiring. This involves crossing the wrong wire in a vehicle to trick the ECU. This is a risky method and requires a lot of experience to avoid electrocuting oneself. Modern broken car key repair car thieves are also using more advanced methods, like Bluetooth or specialised apps to steal a car's information and remotely manage it.
Owners of cars will often see warning lights that indicate an immobiliser that has gone out of control. This can happen for various reasons, but the most frequent is due to a damaged or dead battery in the key fob. A simple repair should resolve this issue.
If this does not work, it could be that the transponder chip may be defective or the ECU is not compatible. This is more difficult to fix and diagnose as it may require an expert locksmith or a dealership. A car's immobiliser can be damaged if water manages to get into the system or if it is physically removed from its fob or key. If any of these issues occur it's a good idea visit an auto garage or a local dealer to seek assistance.
