Typically, the key fob battery powers the remote locking and opening systems. However, it doesn't supply power to the immobiliser. Instead, the immobiliser depends on the transponder chip located in the fob or key. The chip transmits a passcode from the fob or key to the immobilizer unit in the car, which could be integrated into the PCM (power control module) BCM (brake control module), instrument cluster smart junction boxes or standalone modules. The system examines the code to make sure it's correct. If it is 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 you don't have the right key.
Since its introduction the immobiliser has proven to be an extremely effective tool in reducing car theft. Yet, thieves are constantly trying to get around these security measures. One of these is the Kia Challenge trend on TikTok that demonstrates how easy it can be to hot-wire an vehicle.
Many insurance companies are now incorporating in the use of an immobiliser in calculating premiums, which makes it even more appealing to shop for a car that already has this feature. However, even vehicles that came factory-fitted with an immobiliser can experience problems with it. Fortunately, these issues are usually simple and inexpensive to repair. A dead or dying keyfob battery is usually the cause of a faulty ignition immobiliser. A quick diagnostic test could identify the issue. If the problem persists then it could be due to electrical problems or wiring issues. It is recommended to have a professional diagnose the problem and fix it.
Transponder Chip
A tiny electronic chip, referred to as a transponder, is built into the head portion of your car keys. The technology was introduced in cars made after 1995. It is also referred to a "chip key" or a "transmitter-responder" key. Its purpose is to stop your engine from starting when another person has an identical key. It works by transmitting an audio frequency signal from the key to the immobiliser system in your car. If the code on the car's computer matches the signal from the key, it will disarm 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 because it is more difficult to duplicate than a conventional mechanical key. Utilizing special techniques, it is feasible to copy a standard car key however, not the transponder key. In contrast to the central locking element remote of a standard key that relies on battery power, a transponder chip powered by the infrared (IR) signal that is transmitted by the antenna ring that is located on the ignition cylinder.
To turn on the transponder, the ignition cylinder must be in the ON position. The ring emits a burst IR energy that is received by a microchip within the key. The chip responds with a unique code to the immobiliser in your car. The computer in the car examines the code in its memory to the transponder's and if the two codes match it will start the engine.
If the immobiliser is able to detect an unauthorised transponder, key or other device is being used it will shut down the engine and stop any of its vital components from functioning. The car will not move if the engine is not working. It is easy for a criminal to hot-wire it and then drive off. This is a powerful way to deter crime, and is one of the reasons why it is essential to get your car key immobiliser repaired immediately you discover any issue with it. If you don't do this, the security light in your car will continue to flash and it will be difficult to start your engine.
Security Light
The immobiliser is powered by a small battery that sends an electrical signal to the transponder chip within your key. This anti-theft device prevents anyone from starting the car without the correct keys. If the system cannot detect a serial number digital from the chip in your key it will disengage the engine immobiliser, preventing the car from getting started.
This car immobiliser system is an effective way to stop thieves, however it can get out of sync with the key or transponder chip. This can be due to interference or the system being too sensitive. If this is the case, it may need to be reset. To do this simply disconnect the battery. After 15 minutes, you can reinstall the battery and then restart the car. This will reset the system and allow it to accept your key again.
The security light is the vehicle immobiliser's method of letting you know that there is a problem with the system. If you try to start the car but the light stays on, it means that the chip inside your key isn't compatible with the code stored in the ECU. This could happen when your car's key has been replaced by a new one that is not programmed to work with the vehicle, or if an ECU was not swapped correctly.
If this is the situation, then it's time to go to a professional and have the transponder or key chip properly programmed to your vehicle. It's possible that the system won't accept the key because of a software update or bug. To test, insert your key in the ignition and turn the ON position. Do not try to start the vehicle. The key should remain in this position for 10 minutes. This should cause the security light to light up and then to turn off. If it doesn't work, you'll need to repeat the procedure and wait another 10 minutes. This should resolve the issue if you repeat it three times.
Programming
An immobiliser for cars prevents a car's engine from running without a key that is programmed correctly or fob. It utilizes a specific RFID chip that is unable to be copied and is equipped with a digital serial number. The immobiliser will be disconnected if it does not recognise the code. It's tough to beat.
Modern cars are fitted with this security system as standard. This makes it very difficult to hot-wire the car or use another key for starter. The system works by analyzing the chip inside a key fob or a key and sending a passcode back to the ECU (electronic control unit). The ECU will then verify that it's the correct key and that the code hasn't been compromised. The system won't allow the vehicle to start if it doesn't receive the correct code. Some models will even report back to the owner if someone tries to use a wrong key or fob.
The system isn't impervious to attack, but it is. Certain thieves have been able to bypass the immobiliser using methods such as 'hot-wiring'. This involves crossing the wrong wires within a vehicle's wiring to fool the ECU into thinking that the proper key or fob is being used. However, this is quite dangerous and requires a lot of experience in order to do it without electrocuting yourself. Modern car thieves are using more advanced methods, for instance, Bluetooth or specialised apps to take over a car's data and remotely manage it remotely.
Car owners are often faced with broken key repair warning lights that signal that the immobiliser has gone haywire. This could be due to a variety of reasons, but the most frequent causes is a faulty or dead battery on the key fob. A simple replacement should fix this issue.
If this doesn't work the transponder chip could be faulty or mismatched with the ECU. This is more difficult to fix and diagnose as it could require a specialist locksmith or dealership. The car immobiliser could also be damaged if water manages to enter the system, or if it is physically pulled away from its fob or key. If you experience any of these issues, it is a good idea that you visit an auto dealer in your area or garage to seek help.
