Typically, the key fob battery powers the remote opening and locking systems. The immobiliser isn't powered by the key fob battery. The immobiliser is powered through the transponder in the fob, key or instrument cluster. The chip transmits a code from the key or fob to the immobilizer unit of the car. It can be integrated into the PCM (power control module) or BCM (brake control module for brake control) instrument cluster, smart junction boxes, or standalone modules. The system checks the code to make sure it is correct. If the code is not correct, the system disables elements that are crucial to start the car, like the ignition or starter motor. This will make the car nearly impossible to start if you don't have the right key.
The immobiliser has proven extremely effective at cutting down on car theft since its introduction. However the thieves are always seeking ways to bypass these security measures. One of these methods includes a recent trend called the Kia Challenge on TikTok that demonstrated how easy it is to wire a vehicle.
Insurance companies are now incorporating in the use an immobiliser when calculating premiums. This makes it more appealing to buy a car with this feature. Even cars that are factory fitted with an immobiliser could be prone to problems. Fortunately, these issues are usually simple and inexpensive to repair. A dying or dead keyfob battery can be the cause of a malfunctioning ignition immobiliser. This can be confirmed with a quick diagnostic test. If the problem persists then it could be due to electrical issues or wiring issues. It is recommended to have 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. It is also known as a "chip key" or a "transmitter-responder" key. Its function is to stop your engine from starting when you have a duplicate of your key. car key repairs works by transmitting a radio frequency signal from the key to the immobiliser system inside your car. If the code in the car's computer matches that signal sent from the key, it will disable the immobiliser and allow the engine to begin.
The key with the transponder chip is sometimes called"fob" or a "smart" key because it is more difficult to clone than a conventional mechanical key. Utilizing specific methods, it is possible to copy a standard car key, but not transponder keys. Unlike the remote central locking element of a conventional key, which uses battery power the 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, the ignition cylinder has to be in the ON position. The ring emits a burst IR energy which is detected by a microchip within the key. The chip responds by sending a unique code to the immobiliser in your car. The car's computer compares the code stored in its memory with the one from the transponder chip and if they match, the engine will start.
If the immobiliser detects that an unauthorized transponder or key is in use it will shut down the engine and stop any of its essential components from working. The car won't move if the engine is not working. It would be easy for a criminal hot-wire it and drive off. This is a powerful deterrent to crime, and is one of the main reasons why it's essential to have your car's key immobiliser fixed immediately you discover a fault with it. 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 is powered by a small battery that sends an electric signal to the transponder chip within your key. This anti-theft device prevents anyone from starting the car if they don't have the proper keys. If the system is unable to detect a serial number digital from the chip inside your key it will disengage the engine immobiliser, preventing the car from starting.
This car immobiliser system is effective in stopping thieves, however it can become out of sync with the key or the transponder chip. This could be due to interference or the system being too sensitive. If this is the case it could be necessary to reset. To do this simply disconnect the battery. After 15 minutes, reconnect the battery and then restart the car. This will reset the system and allow it 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 on and you try to start your car, it is a sign that the code in the ECU does not match the chip inside the key. This could happen if you have recently replaced your car's key with another that isn't programmed to the vehicle or if you've had a bad swapped ECU.
If this is the case you should take your key or transponder chip to a professional for them correctly programmed for the vehicle you are driving. There is also the possibility that the system is not accepting the key because of an issue with the software or an update. To test this, insert your key into the ignition and then turn it to the ON position. Do not attempt to start the vehicle. Keep the key in this position for ten minutes. This should cause the security light to turn on and to turn off. If it doesn't then you'll have to repeat the procedure and wait another 10 minutes. Repeat the process three times, and the issue is likely to be solved.
Programming
The car immobiliser stops the engine from running if a key or fob is not programmed correctly. It uses a special RFID chip that cannot be copied and has a digital serial number. The immobiliser will stop working if it doesn't recognise the code. It's tough to beat.
Modern cars have this system as standard. This makes it really hard to hot-wire the car or use another key for 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 then knows that it's the right key and that the code hasn't been compromised. The system won't allow the car to start if it doesn't receive the correct code. Some models will even inform the owner in the event that someone attempts to use an unapproved key or fob.
The system isn't foolproof, however. Some thieves have managed to bypass the immobiliser by using techniques such as 'hot-wiring.' This involves crossing the wrong wires in the wiring of a vehicle, which fools the ECU into thinking that the correct key or fob is being used. But, this technique is pretty risky and requires a lot of experience to do it without cutting yourself. Modern car thieves are employing more sophisticated methods like Bluetooth or specialised apps to obtain information about a vehicle and remotely manage it.
Car owners will often get warning lights that indicate the immobiliser has gone off the rails. It can happen for many reasons but the most frequent one is a malfunctioning battery in the keyfob. The issue can be solved by an easy replacement.
If this doesn't work the transponder chip could be defective or not compatible with the ECU. This is more difficult to fix and diagnose as it may require a professional locksmith or dealership. However, a car immobiliser can also be damaged due to water intrusion, or even being removed from the fob or key. If you encounter any of these issues it is a great idea that you visit an auto dealer in your area or garage to seek help.
