The key fob battery powers the remote key repair locking and opening systems. However, it doesn't supply power to the immobiliser. The immobiliser is powered through the transponder located in the key, fob or instrument cluster. The chip transmits a code from the key or fob to the immobilizer module of the car. It can 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 it is correct. If it is not, the system will disable parts that are essential to start the vehicle, such as the starter motor or ignition. The car will be nearly impossible to start if you do not have the correct key.

Transponder Chip

In cars made after 1995, a tiny electronic chip, referred to as a transponder is built into the head of your car key. It is also known as a "chip key" or a "transmitter-responder" key. Its purpose is to prevent your engine from starting if someone else 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 stored in the computer of the car matches the signal sent by the key, the immobiliser will be disarmed and the engine will start.

The key with the transponder chip can be referred to as a 'fob' or a "smart" key due to the fact that it is more difficult to clone than a conventional mechanical key. It is possible to duplicate a conventional key but not a transponder one. Transponder chips are powered by an infrared signal and not battery power.

To activate the transponder the ignition cylinder has to be in the ON position. The ring emits IR energy which is received by a microchip within the key. The chip then sends an individual code to the immobiliser in your car. The computer in the car compares the code stored in its memory to the transponder's and If the two codes are identical it will start the engine.

If the immobiliser detects an unauthorized transponder or key is in use, it will disable the engine and stop any of its vital components from working. Without a functioning engine the car will not be able to move, and it would be very easy for criminals to hot-wire the vehicle and then drive away.

The car immobiliser is a great method to deter thieves, but it can sometimes get out of in sync. This could be due to interference or the system is too sensitive. This could require a reset. To do this, simply disconnect the battery. Then leave it off for around 15 minutes then reinsert it and start the car. This will reset the key system, so that it is ready to accept keys once more.

The security light is the car immobiliser's method of letting you know that there's a problem with the system. If the light is on when you try to start your car, it means that the code in the ECU does not match the chip in the key. This could happen if you have recently replaced your car key with one that isn't programmed to the vehicle or if you've had a bad swapped ECU.

If this is the situation you should take your key or transponder chip to a professional to get them correctly programmed for the vehicle you are driving. It is possible that the system won't accept the key due to a software update or glitch. To test, insert your key in the ignition and then turn it to the ON position. Don't try to start the vehicle. Let the key stay in this position for ten minutes. The security light should come on, then turn off. If it doesn't then you'll need to repeat the procedure and wait another 10 minutes. This should resolve the issue if you repeat it three times.

Programming

Modern cars are equipped with this security system by default. This makes it extremely difficult to hot-wire the car or use a different key for starter. The system works by analyzing the chip in a key fob or key, and transmitting a passcode to the ECU (electronic control unit). The ECU recognizes that it is the correct key and that there hasn't been a compromise in the code. The system won't allow the car to start if it does not receive the correct code. Some models will even notify the owner if a person tries to use a wrong key or fob.

However the system isn't impervious to theft. Some thieves have managed to bypass the immobiliser with techniques such as 'hot-wiring.' This involves crossing the wrong wires within a vehicle's wiring to fool the ECU into thinking the appropriate fob or key is being used. However, this is quite risky and requires a great deal of experience in order to carry out the procedure without cutting yourself. In addition, many modern car thieves have moved over to more advanced methods, such as using specialized apps or Bluetooth to hijack the car's information and remotely control it via their mobile.

Owners of cars will often be greeted by warning lights that indicate an immobiliser gone haywire. This could be due to many reasons however the most common one is a faulty battery in the keyfob. A simple replacement can fix the issue.
