The immobiliser is powered through the transponder that is located in the fob, key or instrument cluster. The chip transmits a passcode from the key or fob to the immobilizer module of the car, which can be integrated into the PCM (power control module) BCM (brake control module for brake control), instrument cluster, smart junction boxes, or standalone modules. The system will check the code to make sure it's correct. If the code is not correct, the system disables components that are crucial to starting the car, such as the starter motor or ignition.

The immobiliser system has been highly effective in reducing car theft since its first introduction. Despite this, thieves are always looking for new ways to bypass these security measures. One of these methods is the Kia Challenge trend on TikTok that shows how simple it is to wire an automobile.

In vehicles manufactured after 1995, a small electronic chip referred to transponder is integrated into the head of your car key. Also known as a chip key or a 'transmitter & responder key, it is designed to stop the engine from starting if someone else has the same key. It works by sending an audio frequency signal from the key to the immobiliser system inside your car. If the code on the car's computer is in line with the signal from the key, it will deactivate the immobiliser and allow the engine to start.
The key with the transponder chip can be referred to as"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 key. In contrast to the remote central locking element of a standard key that relies on battery power, a transponder chip is powered by the infrared (IR) signal transmitted by the antenna ring on the ignition cylinder.
To activate the transponder, the ignition cylinder has to be in the ON position. The ring emits a burst IR energy which is picked up by a microchip within the key. The chip responds with an individual code to the immobiliser inside your car. The car's computer analyzes the code stored in its memory with the transponder's code and If the two codes are identical, it will start the engine.
The immobiliser will shut down the engine when it detects an unauthorised key or transponder. It also blocks any essential parts of the car from working.

This anti-theft device stops anyone from starting the car without the proper keys. If the system is not able to recognize an electronic serial number from the chip on your key, it will disable the engine immobiliser to stop the car from starting.
This car immobiliser system is an effective way to stop thieves, but it is also possible for it to get out of connection with the key or transponder chip. This can be caused by interference or the system being too sensitive. If this is the situation, it may need to be reset. To do this, simply disconnect the battery. It should be left disconnected for around 15 minutes before reinstalling it and start the vehicle. 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 attempt to start the car and the light stays on, it means that the chip in your key isn't in sync with the code that is stored in the ECU. This can occur when your car's key has been replaced by a new key that's not compatible with the vehicle, or if the ECU was swapped in a wrong manner.
If this is the case then it's time to talk 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 a software bug or update. To test this put your key in the ignition and turn it to the ON position but don't attempt to start the engine. Let the key remain in this position for ten minutes. The security light should turn on, then go off. If it doesn't then you'll need to repeat the process and wait for another 10 minutes. This should resolve the issue when you repeat the process three times.
Programming

The immobiliser will be disconnected if it does not recognise the repair car keys near me code. It's difficult to beat.
Modern cars have this system as standard. This makes it extremely difficult to hot-wire a vehicle or use a different key as a 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 is then able to determine that it's the right key and that the passcode hasn't been compromised. The system won't permit the car to start if the doesn't receive the correct code, and some models will even report back to the owner if a person tries to use an incorrect key or fob.
The system isn't impervious to attack, but it is. Some thieves have gotten around the immobiliser by using techniques like 'hot-wiring.' This involves crossing the wrong wires through the wiring of a vehicle to trick the ECU to believe that the proper key or fob is being used. This is a risky method and requires a lot of experience to avoid electrocuting oneself. Plus, a lot of modern car thieves have moved over to more advanced methods such as using specialised apps or Bluetooth to steal the car's information and remotely control it using their phones.
Car owners will frequently be greeted by warning lights that indicate an immobiliser malfunctioning. This could be due to a variety of reasons, but one of the most frequent is a faulty or dead battery in the key fob. A simple replacement should fix the issue.
If this doesn't work, it could be that the transponder chip is defective or the ECU is mismatched. This is more difficult to diagnose and fix because it requires a specialist locksmith for cars or a dealership.
