Typically the key fob battery powers the remote opening and locking systems. The immobiliser isn't powered by the battery in the key fob. Instead, the immobiliser relies on the transponder chip in the fob or key. The chip transmits a code from the key or fob to the immobilizer unit of the car, which could 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 that it is correct. If the code isn't correct, the system disables components that are crucial to the start of the car, such as the ignition or starter motor. The car will be impossible to start if you do not have the correct key.
Since its inception the immobiliser has proved to be an extremely effective tool in decreasing car theft. Yet, thieves are constantly trying to get around these security measures. One of these methods is the Kia Challenge trend on TikTok, which shows how easy it is to wire an vehicle.
Most insurance companies now factor in the use of an immobiliser when calculating premiums, which makes it more appealing to buy an automobile that has this feature. However, even vehicles that came factory-fitted with an immobiliser may experience problems with it. Fortunately, these problems are usually straightforward and affordable to repair. A dying or dead keyfob battery is usually the cause of a malfunctioning ignition immobiliser. A quick diagnostic test can uncover the problem.

Transponder Chip
In vehicles manufactured after 1995, a tiny electronic chip, referred to as transponder is embedded in the head of your car key. It is also referred to a "chip key" or a "transmitter-responder" key. Its purpose is to prevent your engine from starting if you have an identical key. It works by sending the radio frequency signal from the key to the immobiliser system inside your car. If the code in the car's computer matches the signal transmitted by the key, it will disable the immobiliser and allow the engine to start.
The key that has the transponder chip is often referred to as"fob" or a smart key due to the fact that it is more difficult to copy than a traditional mechanical key. Using special techniques, it is possible to duplicate a standard car key but not the transponder key. In contrast to the remote central locking element of a conventional key which uses battery power, a transponder chip is powered by the infrared (IR) signal transmitted by the antenna ring that is located on the ignition cylinder.
To activate the transponder chip, the ignition cylinder needs to be turned to the ON position. The ring emits IR energy that is detected by a microchip in the key. The chip responds by transmitting a unique code to the immobiliser of your car. The car's computer compares the code in its memory to the one from the transponder chip, and if they match the engine will be able to start.
If the immobiliser is able to detect an unauthorised transponder or key is being used it will shut down the engine and stop the essential components from functioning. The car won't move when the engine isn't working. It would be easy for criminals to wire it and then drive off.

If you don't do this and the security light on your car will keep flashing and you will not be able to begin it.
Security Light
The immobiliser uses a small battery to transmit an electrical signal to the chip inside your key. This anti-theft device prevents anyone from starting the car without the correct keys. If the system cannot detect an electronic serial number from the chip in your key, it will shut off the engine immobiliser to stop the car from starting.
This car immobiliser system is an effective way to stop thieves, however it can become out of sync with the key or transponder chip. This can be due to interference or the system becoming too sensitive. If this is the situation, it might need to be reset. To do this, simply disconnect the battery. After 15 minutes, reconnect the battery and restart the car. This will reset the key system, so that it is ready to accept your keys again.
The security light is a way of warning you of the presence of a problem. If the light is illuminated and you try to start your car, it is a sign that the code stored in the ECU does not match the chip in the key. This could happen if have recently replaced your car key with another that was not programmed to the vehicle, or if you've had a bad swapped ECU.
If this is the case then it's time to talk to a professional for assistance and get the the transponder chip properly programmed to your vehicle. It's possible that your system won't accept the key due to a software update or glitch. To test this put your key in the ignition and switch it to ON but don't try to start the engine. Keep the key in this position for ten minutes. This should cause the security light to light up and then to go off. If it doesn't, you'll need to repeat the process and wait another 10 minutes. Repeat the process three times and the problem should be solved.
Programming
An immobiliser for cars prevents a car's engine from running without a key that is programmed correctly or fob. It is based on a specific RFID micro-chip that can't be duplicated and comes with its own serial number. The immobiliser will stop working in the event that it is unable to recognize the code. This is why it's so hard to beat.
Modern cars are equipped with this security system by default. car key fob repairs makes it very difficult to wire a car or utilize a different key for starter. The system works by checking the chip in the key fob or a key and transmitting a passcode to the ECU (electronic control unit). The ECU is aware that it's the right key and that it doesn't have to been compromised code. The system will not allow the car to start if it does not receive the correct code, and some models will even inform the owner in the event that someone attempts to use an incorrect fob or key.
However the system isn't foolproof. Some thieves have managed to bypass the immobiliser using methods such as 'hot-wiring'. This involves using the wrong wiring in a vehicle to cause a malfunction in the ECU. But, this technique is extremely risky and requires a great deal of experience to do it without electrocuting yourself. Modern car thieves are also employing more sophisticated methods, for instance, Bluetooth or other specialized apps to take over a car's data and remotely manage it remotely.
Car owners often see warning lights that signal that the immobiliser is malfunctioning. This can occur for various reasons but the most frequent one is a faulty battery in the keyfob. A simple replacement should fix this problem.
