The key fob battery is used to power the remote locking and opening systems. However, it doesn't provide power to the immobiliser. The immobiliser is powered through the transponder 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 examines the code to make sure that it is correct. If the code is not correct it will disable the components that are crucial to the start of the car, such as the ignition or starter motor. The car will be nearly impossible to start if the driver doesn't have the right key.

Since its inception, the immobiliser has been a very effective tool in reducing car theft. Even so the thieves are always seeking ways to bypass these security measures. One of these methods includes a recent trend known as the Kia Challenge on TikTok that showed how easy it was to wire a vehicle.

Insurance companies are now incorporating the use of an immobiliser when calculating premiums. This makes it more appealing to buy a car with this feature.

A quick diagnostic test can uncover the problem. If the issue continues to persist, then there might be other causes for the vehicle's misbehaviour, including electrical issues or a wiring issue. It is best to let a professional diagnose the problem and solve it.

Transponder Chip

A tiny electronic chip, called transponder, is incorporated into the head portion of your car keys. This technology was introduced in vehicles manufactured after 1995. Also referred to as a 'chip key' or a 'transmitter and responder' key, it is designed to prevent the engine from starting if another person has the same key. It works by transmitting an audio signal from the key to your immobiliser. If the code stored in the computer of the car matches the signal transmitted by the key the immobiliser will then be disarmed and the engine will be able to start.

The key that has the transponder chip is sometimes called"fob" or a "smart" key because it is much more difficult to clone than a traditional mechanical key. Utilizing special methods, it is possible to duplicate a standard car key however, not the transponder key. Transponder chips are powered by an infrared signal, not battery power.

To turn on the transponder, the ignition cylinder has to be in the ON position. The ring emits a blast of IR energy which is detected by the microchip in the key. The chip responds by transmitting a unique code to the immobiliser of your car. The car's computer compared the code in its memory to the one from the transponder chip and If they are compatible, the engine will start.

If the immobiliser is able to detect an unauthorised transponder, key or other device is in use, it will disable the engine and block any of its vital components from working. The car will not move when the engine isn't working. It is easy for a criminal hot-wire it to drive away. This is a powerful security measure against crime, and is the reason why you should get your car key-immobiliser repaired as soon as you can in the event of a malfunction. If you do not take action then the security light on your vehicle will continue flashing and you will not be able to begin it.

Security Light

The immobiliser is powered by a tiny battery that transmits an electrical signal to the transponder chip in your key. This anti-theft device prevents anyone from starting their car without the correct keys. If the system is unable to detect a digital serial number from the chip in your key, it will deactivate the engine immobiliser, preventing the car from starting.

The car immobiliser is a fantastic way to deter thieves, but it can sometimes be out of the sync. This could be due interference or an immobiliser that is too sensitive. If this is the situation, it could be necessary to reset. To do this, simply disconnect the battery. Then leave it off for around 15 minutes, then insert it and start the car. This will reset the system and make it ready to accept the key again.

The security light is the car immobiliser's method of letting you know that there's an issue with the system. If the light is illuminated and you try to start your vehicle, it indicates that the code in the ECU does not match the chip on the key. This could happen if your car key was replaced with a new one that is not programmed to work with the vehicle, or if an ECU was swapped in a wrong manner.

If this is the case, 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 is not accepting the key due to a software bug or update. To test, put your key into the ignition and then turn it to the ON position. Do not try to start the car. Keep the key in this position for 10 minutes. The security light should turn on, then turn off. If it doesn't, you'll have to repeat the process and wait for another 10 minutes. This should resolve the issue if you repeat it three times.

Programming

A car immobiliser prevents a car's engine from running without a correctly programmed key or fob. It makes use of a unique RFID microchip that cannot be copied and has its own digital serial number. The immobiliser will disengage when it is unable to recognize the code. That's why it's so difficult to beat.

Modern cars come with this system as standard. This makes it extremely difficult to hot-wire a car or use a different key as a 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 is then able to determine that it's the correct key and that the code isn't compromised. The system won't permit the vehicle to start if it does not receive the correct code. Some models will even inform the owner if a person tries to use an incorrect fob or key.

The system isn't completely foolproof, however. Some thieves have managed to bypass the immobiliser using methods such as 'hot wiring.' This involves crossing the wrong wiring in a vehicle in order to cause a malfunction in the ECU. However, this is pretty risky and requires a lot of experience to do it without cutting yourself. Additionally, many modern car thieves have shifted over to more advanced methods, such as using specialized apps or Bluetooth to hijack the car's information and remotely control it using their phones.

Car owners often see warning lights that indicate the immobiliser has gone haywire. This can happen for various reasons, but the most frequent causes is a faulty or dead battery on the key fob. This problem can be fixed by an easy replacement.

If this isn't working, the transponder chip might be defective or mismatched with the ECU. This is more difficult to diagnose and fix as it may require a specialist locksmith or dealership. However, a car's immobiliser may be damaged by water intrusion, or even being removed from the fob or key. If any of these problems occur, it's a good idea visit a local garage or car dealer for assistance.
