The key fob battery powers the remote locking and opening systems. However, it doesn't power the immobiliser. Instead, the immobiliser is dependent on the transponder chip located on the fob or key. The chip transmits a passcode from the fob or key to the immobilizer unit 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 then checks the code to make sure it is correct. If it's not then the system will disable parts that are essential to start the vehicle, such as the ignition or starter motor. The car will be impossible to start if the driver doesn't have the right key.
Since its introduction the immobiliser has proven to be an extremely effective tool in reducing car theft. However the thieves are always seeking ways to bypass these security measures. One of these techniques is an upcoming trend called the Kia Challenge on TikTok that demonstrated how easy it is to hot-wire a vehicle.
Many insurance companies are now incorporating in the use of an immobiliser when calculating rates, which makes it even more appealing to purchase a car that already has this feature. Even cars that are factory-fitted with an immobiliser could be prone to problems. Fortunately, these issues are usually straightforward and affordable to repair. Most times, a faulty immobiliser is caused by an inactive or dead key fob battery. This can be determined by an instant diagnostic test. 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 cars manufactured after 1995, a small electronic chip, referred to as a transponder is built into the head of your car key. It is also referred to as a "chip key" or a "transmitter-responder" key. Its goal is to prevent your engine from starting when someone else has a duplicate of your key. It works by transmitting an audio signal from the key to your immobiliser. If the code in 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 a transponder can also be referred to as a "fob" or a "smart" key, because it is more difficult to copy than a mechanical key. With the help of special methods, it is possible to duplicate a standard car key, but not transponder keys. In car remote key repair to the central locking element remote of a conventional key which uses battery power, a transponder chip is powered by an infrared (IR) signal that is transmitted by the antenna ring that is located on the ignition cylinder.
To activate the transponder chip, the ignition cylinder has to be turned on. The ring emits a burst of IR energy, which is absorbed by the microchip within the key. The chip then responds with a unique code to the immobiliser inside your car. The car's computer analyzes the code stored in its memory to the transponder's and if the two codes match it will begin the engine.
The immobiliser will shut down the engine in the event of an unauthorized key or transponder. It will also prevent all vital components of the vehicle from functioning. Without a functioning engine the car will not be able to move and it could be easy for a criminal to wire the vehicle and then drive off. This is a powerful security measure against crime, and is why you should have your car's key-immobiliser fixed as soon as you can in the event of a malfunction. If you don't do this, the security light on your car will keep flashing and it will be impossible to start your engine.
Security Light
The immobiliser makes use of a tiny battery to send an electrical signal to the chip in your key. This device is designed to prevent anyone from starting the car without the proper keys. If the system is unable to detect an electronic serial number from the chip on your key, it will disable the engine immobiliser to stop the car from starting.
The car immobiliser is a great method to deter thieves, but it can occasionally be out of in sync. This could be due interference or the system is too sensitive. If this is the case, it may need to be reset. To do this, simply disconnect the battery. Leave it disconnected for about 15 minutes, then insert it and begin the vehicle. This will reset the key system so that it is ready to accept your keys again.
The security light is an immobiliser's way of warning you of an issue. If the light is on and you attempt to start your vehicle, it indicates that the code stored in the ECU is not compatible with the chip in the key. This can occur if your car key has been replaced by a new one that is not programmed for the vehicle, or if the ECU was swapped in a wrong manner.
If this is the situation, it's best to bring your transponder key or chip to a professional to get them properly programmed for your vehicle. There is also the possibility that the system isn't accepting the key due to an issue with the software or an update. To test this, put 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, and then go off. If it doesn't work, you'll have to repeat the process and wait for another 10 minutes. Repeat the process three times, and the issue will be resolved.
Programming
The car immobiliser blocks the engine from running if the fob or key are not properly programmed. It makes use of a unique RFID micro-chip that can't be duplicated and comes with its own serial number. The immobiliser will stop working when it doesn't recognize the code. That's why it's difficult to beat.
Modern cars come with this security system by default. This makes it extremely difficult to wire a car or use a different key for starter. The system works by sending a passcode from the key fob to the ECU. The ECU then knows that it's the correct key and that the passcode hasn't been compromised. The system will not allow the car to begin when it doesn't receive the correct code. Certain models will even notify the owner if they attempt to use a wrong fob or key.
The system isn't completely impervious to attack, but it is. Some thieves have gotten around the immobiliser using methods such as 'hot-wiring.' This involves using the wrong wiring in an automobile to cause a malfunction in the ECU. This is a risky method and requires a lot of knowledge to avoid electrocuting oneself. Modern car thieves are employing more sophisticated methods for instance, Bluetooth or other specialized apps to steal a car's information and remotely control it remotely.
Owners of cars will often be greeted by warning lights that indicate an immobiliser gone haywire. This could be due to a variety of reasons, but one of the most frequent is a dead or defective battery in the key fob. A simple replacement can fix this problem.
If this does not work, it could be that the transponder chip may be defective or the ECU is not matched. This is more complicated to diagnose and fix, as it can involve an expert locksmith for cars or a dealership. However, a car's immobiliser can also be damaged by water ingress or even physically being pulled away from the fob or key. If you encounter any of these problems, it is a good idea to consult a local car dealer or garage to seek help.
