This chip transmits a code to the car's immobilizer unit, which may be built into the PCM, BCM or instrument cluster smart junction box or standalone module. The system examines the code to make sure it is correct. If the code isn't correct, the system disables elements that are crucial to the start of the car, like the ignition or starter motor. This makes the car nearly impossible to start without the right key.
The immobiliser system has been extremely effective at cutting down on car theft since it was first introduced. Even so the thieves are always seeking ways to bypass these security measures. One of these methods is the Kia Challenge trend on TikTok, which shows how easy it is to wire an vehicle.

If the problem persists then it could be due to electrical problems or wiring issues. It's best to let a professional determine the issue and fix it.
Transponder Chip
In vehicles manufactured after 1995, a small electronic chip referred to transponder is embedded in the head of your car key. It is also known as a "chip key" or a "transmitter-responder" key. Its purpose is to prevent your engine from starting when you have the same key. It works by transmitting a radio frequency from the key to your immobiliser. If the code in the car's computer matches the signal from the key, it will deactivate the immobiliser and allow the engine to start.
The key that is equipped with a transponder chip is often referred to as a 'fob' or a smart key because it is much more difficult to duplicate than a traditional mechanical key. It is possible to duplicate a standard key, but not a transponder key. Unlike the central locking element remote of a conventional key which is powered by batteries, a transponder chip powered by an infrared (IR) signal that is transmitted through the antenna ring on the ignition cylinder.
To activate the transponder chip the ignition cylinder has to be switched to ON. The ring emits IR energy which is detected by a microchip in the key. The chip then sends an unique code to the immobiliser inside your car. The computer in the car compares the code stored in its memory with the transponder's and when the two codes match, it will start the engine.
The immobiliser will disable the engine when it detects an unauthorised key or transponder. It also blocks any essential components of the car from functioning. The car will not move if the engine is not working. It's easy for a criminal to hot-wire it and drive off. This is a powerful deterrent against crime, and is one of the reasons why it is essential to get your car's key immobiliser repaired immediately you discover a fault with it. If you do not take action and the security light on your car key repairs near me will keep blinking, and you won't be able to start it.
Security Light
The immobiliser is powered by a small battery that transmits an electrical signal to the transponder chip within your key. This is an anti-theft device that prevents anyone from starting your car without the correct key. If the system is not able to recognize a digital serial from the chip in your key, it will disable the engine immobiliser, which will stop the car starting.
The car immobiliser is a great method of deterring thieves, however it can sometimes be out of in sync. This can be due to 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. After 15 minutes, reconnect the battery and then restart the vehicle. This will reset the key system so that it is ready to accept your keys again.
The security light is a way of alerting you to an issue. If you attempt to start the car and the light is solid on it means that the chip inside your key isn't compatible with the code that is stored in the ECU. This could happen if you have recently replaced your car key with one that has not been programmed to the vehicle, or when you've had a damaged swapped ECU.
If this is the case then it's time to go to a professional to have the transponder or key chip properly programmed to your vehicle. It's possible that your system won't accept the key due to a software upgrade or glitch. To test this, place your key in the ignition and switch it to ON but don't try to start the engine. The key should remain in this position for ten minutes. The security light should come on, then go off. If it does not, you will need to repeat the process and wait for another 10 minutes. Repeat this three times, and the issue should be solved.
Programming
The car immobiliser stops the engine from running when the fob or key is not properly programmed. It makes use of a unique RFID micro-chip that can't be copied and has its own digital serial number. The immobiliser will be disconnected in the event that it is unable to recognize the code. This is why it's so hard to beat.
Modern cars come with this security system as standard. This makes it difficult to hot-wire a vehicle or use a different key as a starter. The system works by checking the chip inside a key fob or a key and transmitting a passcode to the ECU (electronic control unit). The ECU knows it's the correct key and that there hasn't be compromised code. The system won't allow the car to start in the event that it does not receive the correct code. Certain models will even notify the owner if they attempt to use an unapproved fob or key.
However, the system is not foolproof. Some thieves have been able to bypass the immobiliser using methods such as 'hot-wiring'. This involves crossing the wrong wires through the wiring of a vehicle to trick the ECU to believe that the appropriate fob or key is being used. This method is risky and requires extensive experience to avoid electrocuting oneself. Plus, a lot of modern car thieves have shifted to more sophisticated methods like using specialized apps or Bluetooth to hijack the car's data and then remotely control it from their phones.
Car owners will frequently see warning lights that indicate an immobiliser that has gone out of control. 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. The issue can be solved by an easy replacement.
If this doesn't work, the transponder chip might be faulty or mismatched with the ECU. This is more difficult to determine and fix since it may require an expert locksmith or a dealership. However, a car immobiliser can also be damaged by water ingress or even physically being pulled away from the fob or key. If any of these issues occur it's a good idea to visit the nearest garage or Near dealer for assistance.
