Instead, the immobiliser depends on the transponder chip in the key or fob. The chip transmits a passcode from the key or fob to the immobilizer module of the car, which could be integrated into the PCM (power control module), BCM (brake control module) instrument clusters, smart junction boxes, or standalone modules. The system then verifies the code to ensure that it is correct. If it's not then the system will disable parts that are essential to start the vehicle, like the starter motor or ignition. The car will be impossible to start if the driver doesn't have the right key.
Since its introduction, the immobiliser has been an extremely effective tool for decreasing car theft. Even so the thieves are always trying to get around these security measures.

Transponder Chip
A tiny electronic chip, also known as transponder, is embedded in the head of your car keys. This technology was first introduced in cars made after 1995. It is also referred to as a "chip key" or a "transmitter-responder" key. Its purpose is to prevent your engine from starting when someone else has an identical key. It works by sending radio signals from the key to the immobiliser system. If the code stored in the computer of the car matches the signal sent by the key the immobiliser will be removed and the engine will be able to start.
The key with a transponder is also called a "fob" or a "smart" key, because it is more difficult to duplicate than mechanical keys. It is possible to duplicate a standard key, but not a transponder one. Transponder chips are powered by an infrared signal, not battery power.
To activate the transponder chip the ignition cylinder must be turned to the ON position. The ring emits a burst IR energy that is detected by a microchip in the key. The chip responds with an unique code to the immobiliser of your car. The car's computer examines the code in its memory to the transponder's code and If the two codes are identical it will start the engine.
The immobiliser will shut down the engine when it detects an unauthorised transponder or key. It will also prevent any essential parts of the car from functioning. Without a functioning engine, the car will here not be able website to move and it would be very easy for a criminal to connect the vehicle to a hot wire and drive away.

If you do not take action then the security light on your vehicle will continue flashing and you will not be able to start it.
Security Light
The immobiliser is powered by a small battery that sends an electric signal to the transponder chip in your key. This anti-theft device stops anyone from starting their car without the correct keys. If the system is not able to recognize a digital serial from the chip in your key, it will disable the engine immobiliser to stop the car from starting.
The car immobiliser is a great method of deterring thieves, but it could occasionally be out of in sync. This can be caused by 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. Leave it disconnected for about 15 minutes then reinsert it and begin the car. This will reset the key system, so that it is ready to accept keys once more.
The security light is an immobiliser's method of get more info alerting you to an issue. If the light is illuminated and you attempt to start your car, it is a sign that the code that is stored in the ECU does not match the chip on the key. This could happen in the event that your car's key has been replaced with 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 you should take your transponder or key chip to a professional to have them properly programmed for your vehicle. There is also the possibility that the system is not accepting the key because of an update or software issue.

The security light should turn on, then go off. If it does not, you will need to repeat this process and wait for another 10 minutes. This should solve the problem if you repeat it three times.
Programming

Modern cars have this system as standard. This makes it really hard to hot-wire the car or use a different key for starter. The system works by analyzing the chip in a key fob or a key and sending a passcode to the ECU (electronic control unit). The ECU is then more info able to determine that it's the correct key and that the passcode isn't compromised. The system won't allow the car to start in the event that it does not receive the correct code. Some models even notify the owner if they website attempt to use an incorrect fob or key.
The system isn't completely 100% secure, however. Some thieves have managed to bypass the immobiliser with techniques like 'hot-wiring.' This involves crossing the wrong wires within a vehicle's wiring to fool the ECU to believe that the appropriate fob or key is being used. However, this method is extremely risky and requires a lot of experience to carry out the procedure without cutting yourself. Modern car thieves are also using more advanced methods, like Bluetooth or other apps that take over a car's data and remotely control it remotely.
Car owners will often get warning lights that indicate that the immobiliser has gone off the rails. It can happen for many reasons, but the most common one is a malfunctioning battery in the keyfob. This problem can be fixed by a simple replacement.
If this isn't working, the transponder chip might be defective or mismatched with the ECU. It is more difficult to diagnose and fix because it requires an expert car locksmith or dealership. A car's immobiliser can be damaged if water manages to get into the system, or if it is physically removed from its fob or key. If any of these problems occur it's recommended to visit the nearest garage or dealer to seek assistance.
