Instead, the immobiliser is dependent on the transponder chip in the key or fob. This chip transmits a passcode from the key or fob to the immobilizer unit in the car, which could be integrated into the PCM (power control module) or BCM (brake control module for brake control) instrument cluster smart junction boxes or standalone modules. The system checks the code to ensure it's correct. If it is not, the system will disable parts that are essential to start the vehicle, such as the ignition or starter motor. This will make the car nearly impossible to start without the correct key.
Since its inception the immobiliser has proven to be an extremely effective tool for decreasing car theft. Despite this the fact that thieves are always looking for new ways to get around these security measures. One of these is the Kia Challenge trend on TikTok that demonstrates how easy it is to wire an automobile.

Transponder Chip
In cars made after 1995, a small electronic chip, referred to as transponder is integrated into the head of your car key. Also referred to as a 'chip key or a 'transmitter & responder key, it's designed to prevent the engine from starting if another person has an exact copy of your car key. It works by sending a radio frequency from the key to your immobiliser. If the code on the car's computer is in line with the signal from the key, it will disarm the immobiliser and allow the engine to start.
The key that has the transponder chip is often referred to as a 'fob' or a "smart" key because it is more difficult to copy than a conventional mechanical key. It is possible to duplicate a traditional key, but not a transponder key. Transponder chips are powered by an infrared signal, not battery power.
To activate the transponder, the ignition cylinder has to be in the ON position. The ring emits a burst of IR energy that is detected by the microchip within the key. The chip responds by sending a unique code the immobiliser in your car. The car's computer compared the code in its memory with the one from the transponder chip and If they are compatible the engine will be able to start.
The immobiliser will shut down the engine if it detects an unauthorized key or transponder. It also stops all vital parts of the car from functioning. 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 the reason why you should get your car key-immobiliser repaired promptly in the event of a malfunction. If you don't do this, the security light on your vehicle will continue to flash and it will be difficult to start your engine.
Security Light
The immobiliser is powered by a tiny battery that sends an electric signal to the transponder chip in your key. This is an anti theft device that blocks anyone from driving your vehicle without the proper key. If the system cannot detect an electronic serial number from the chip in your key, it will shut off the engine immobiliser to prevent the car from starting.
The car immobiliser is a fantastic method to deter thieves, however it can occasionally be out of in sync. This could be due to interference or a system that is too sensitive. If this is the situation, it might 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 the key again.
The security light is the vehicle immobiliser's method of letting you know that there is an issue with the system. If you try to start the car and the light stays on it means that the chip in your key isn't compatible with the code stored in the ECU. This can occur if your car key was replaced with a new key that's not compatible with the vehicle, or when an ECU has been swapped incorrectly.
If this is the situation you should take your key or transponder chip to a professional to have them properly programmed for your vehicle. It's possible that your system will not accept the key because of a software update or bug. To test, put your key into the ignition and turn it to the ON position. Do not attempt to start the car. Keep the key in this position for ten minutes. This will cause the security light to turn on and to go off. If it does not then you must repeat this procedure and wait another 10 minutes. Do this three times and the issue should be solved.
Programming
An immobiliser for cars prevents the engine of a car from running without a key that is programmed correctly or fob. It uses a special RFID microchip that cannot be duplicated and comes with its own serial number. The immobiliser will be disengaged in the event that it doesn't recognize the code. That's why it's so difficult to beat.
Modern cars come with this security system as standard. This makes it extremely difficult to wire a car or use a different key for starter. The system works by analyzing the chip inside the key fob or key and sending a passcode to the ECU (electronic control unit). The ECU knows it's the correct key and hasn't been compromised code. The system won't permit the car to start if the doesn't have the correct code, and some models will even notify the owner if someone tries to use an unapproved key or fob.
However, the system is not impervious to theft. Some thieves have gotten around the immobiliser with techniques like 'hot-wiring.' This involves crossing the wrong wires within a vehicle's wiring to fool the ECU to believe that the correct key or fob is being used. This is a risky technique and requires extensive knowledge to avoid electrocuting oneself. Modern car thieves are employing more sophisticated methods like Bluetooth or other specialized apps to take over a car's data and remotely manage it remotely.
Car owners often be greeted by warning lights that indicate an immobiliser gone haywire. This can happen for various reasons, but one of the most frequent causes is due to a damaged or dead battery on the key fob. A simple replacement can fix this issue.
If this isn't working the transponder chip could be faulty or mismatched with the ECU. It is more difficult to fix and diagnose, as it can involve a specialist locksmith for cars or a dealership. However, a car's immobiliser may also be damaged due to water intrusion or even being removed from the fob or key. If any of these issues occur it's a good idea visit a local garage or car dealer for assistance.
