The immobiliser is not powered by the battery in the key fob. Instead, the immobiliser depends 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) or BCM (brake control module), instrument clusters, smart junction boxes, or standalone modules. The system then checks the code to ensure it is correct. If it is not then the system will disable components crucial to starting the vehicle, like the starter motor or ignition. The car will be nearly impossible to start if you do not have the right key. Since its inception the immobiliser has proved to be an extremely effective tool for reducing car theft.

Even vehicles equipped with an immobiliser might be prone to problems. Fortunately, these issues are usually straightforward and affordable to solve. A dying or dead keyfob battery is usually the cause of a malfunctioning ignition immobiliser. This can be determined by an instant diagnostic test. If the issue persists and continues to recur, there could be other causes for the vehicle's irregular behavior, such as electrical problems or a wiring issue. If this is the case, it's recommended to seek out a professional to diagnose and repair the problem. Transponder Chip A tiny electronic chip, referred to as transponder, is incorporated inside the head portion of your car keys. This technology was introduced in cars manufactured after 1995. Also known as a 'chip key or a 'transmitter & responder' key, it is designed to prevent the engine from starting if a third party has the same key. It works by transmitting the radio frequency signal from the key to the immobiliser system inside your car. If the code on the car's computer is in line with the signal transmitted by the key, it will deactivate the immobiliser and allow the engine to start. The key that has a transponder is also called a “fob” or a “smart” key, as it is more difficult to copy than mechanical keys. It is possible to duplicate a traditional key, but not a transponder key. Contrary to the remote central locking element of a conventional key which is powered by batteries, a transponder chip is powered by an infrared (IR) signal transmitted by the antenna ring on the ignition cylinder. To activate the transponder chip, the ignition cylinder has to be turned to the ON position. The ring emits a burst IR energy that is picked up by a microchip inside the key. The chip responds by sending a unique code your car's immobiliser. The car's computer examines the code in its memory with the one on the transponder and when 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 prevent any of its essential components from functioning. The car will not move in the event that the engine is not functioning. It would be easy for a criminal to hot-wire it to drive away. This is a powerful deterrent against criminals and is one of the main reasons why it's important to have your car key immobiliser repaired as soon as you notice a fault with it. If you don't do this and the security light on your car will keep blinking, and you won't be able to start it. Security Light The immobiliser makes use of a tiny battery to send an electrical signal to the chip in your key. This is an anti theft device that blocks anyone from driving your vehicle without the correct key. If the system cannot detect a digital serial from the chip in your key, it will disable the engine immobiliser, which will stop the car from starting. This system for car immobilisation is an effective in stopping thieves, but it is also possible for it to become out of connection with the key or the transponder chip. This could be due to interference or the system becoming too sensitive. If this is the situation, it might need to be reset. To do this, disconnect the battery. After 15 minutes, reinstall the battery and then restart the vehicle. This will reset the system and make it ready to accept the key again. The security light is a way of warning you of the presence of a problem. If you try to start your car and the light stays on it indicates that the chip inside your key isn't compatible with the code that is stored in the ECU. This can happen if your car key was replaced with an alternative key that is not compatible with the vehicle, or if the ECU has been swapped incorrectly. If this is the case then it's time to go to a professional and have the key or the transponder chip properly programmed to your vehicle. 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 put your key in the ignition and turn it to ON but don't attempt to start the engine. Let the key stay in this position for 10 minutes. speaking of will cause the security light to come on and then to turn off. If it does not then you must repeat the process and wait for another 10 minutes. Repeat the process three times and the issue should be solved. Programming A car immobiliser prevents a car's engine from running without a properly programmed key or fob. It uses a special RFID microchip that isn't able to be duplicated and has its own digital serial number. The immobiliser will disconnect when it doesn't recognize the code. This is why it's so hard to beat. Modern cars are fitted with this security system in the standard configuration. This makes it very difficult to hot-wire a car or utilize a different key for starter. The system works by sending a code from the key fob to the ECU. The ECU will then verify that it's the right 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 100% secure, however. Some thieves have managed to bypass the immobiliser using methods such as 'hot-wiring.' This involves crossing the wrong wires through the wiring of a vehicle, which fools the ECU into thinking that the correct key or fob is being used. This is a risky method and requires a lot of expertise to avoid electrocuting yourself. Modern car thieves are employing more sophisticated methods, such as Bluetooth or other specialized apps to obtain information about a vehicle and remotely manage it. Owners of cars will often be greeted by warning lights that indicate an immobiliser gone haywire. This could be due to many reasons but the most frequent one is a malfunctioning battery in the keyfob. A simple replacement should fix this problem. If this doesn't work, it could be that the transponder chip is faulty or the ECU is mismatched. It is more difficult to diagnose and fix, as it can involve a specialist locksmith for cars or a dealership. However, a car immobiliser can be damaged by water intrusion, or even being removed from the fob or key. If any of these issues occur it's a good idea to visit the nearest garage or dealer to seek assistance.
