This chip transmits a code to the car's immobilizer device, which may be built into the PCM, BCM, the instrument cluster, smart junction box or standalone module. The system will check the code to ensure that it is correct. If the code isn't correct it will disable the components that are essential to starting the car, like the ignition motor or starter motor. The car will be nearly impossible to start if the driver doesn't have the correct key.
Since its inception, the immobiliser has been a very effective tool in decreasing car theft. Despite this the fact that thieves are always looking for new ways to circumvent these security measures.

A tiny electronic chip, also known as transponder, is incorporated in the head 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 function is to stop the engine from starting when another person has the same key. It works by sending radio signals from the key to your immobiliser. If the code stored in the car's computer matches the signal sent by the key the immobiliser will then be removed and the engine will begin to run.
The key with a transponder is also referred to as a "fob" or a "smart" key, because it is more difficult to copy than mechanical keys. Utilizing specific techniques, it is possible to copy a conventional car key however, not a transponder key. In contrast to the central locking element remote of a conventional key, which uses battery power, a transponder chip powered by an infrared (IR) signal that is transmitted by the antenna ring on the ignition cylinder.
To activate the transponder chip the ignition cylinder needs to be switched to ON. The ring emits a burst IR energy which is picked up by a microchip inside the key. The chip responds with an individual code to the immobiliser inside your car. The car's computer checks the code in its car key repair service memory with that from the transponder chip and when they match, the engine will start.
If the immobiliser detects an unauthorised transponder or key is in use it will shut down the engine and block any of its essential components from working. Without a functioning engine, the car will not be able to move and it could be easy for criminals to wire the vehicle and then drive off. This is an effective deterrent to criminals, which is why you should have your car's key-immobiliser fixed as soon as you can in the event of a malfunction. If you don't take this action, the security light on your car will keep flashing and you will not be able to start it.
Security Light
The immobiliser is powered by a small battery that sends an electrical signal to the transponder chip in your key. This anti-theft device prevents anyone from starting the car if they don't have the correct keys. If the system is unable to detect a digital serial number from the chip on your key, it will disable the engine immobiliser to stop the car starting.
The car immobiliser system is an effective in stopping thieves but sometimes it can be out of connection with the key or transponder chip. This can be caused by interference or the system being too sensitive. If this is the situation, it might need to be reset. To do this, disconnect the battery. Then leave it off for around 15 minutes then reinsert it and start the car. This will reset the system and make it ready to accept the key again.
The security light is the car immobiliser's method of letting you know that there is an issue with the system. If you attempt to start your car and the light is solid on it indicates that the chip inside your key isn't compatible with the code that is stored in the ECU. 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, it's best to take your transponder or key chip to a professional for 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, put your key into the ignition and turn it to the ON position. Don't try to start the car.

This should solve the problem when you repeat the process three times.
Programming
A car immobiliser prevents a car's engine from running without a correctly programmed key or fob. It uses a special RFID chip that cannot be duplicated and has a unique digital serial number. The immobiliser will stop working if it does not recognise the code. That's why it's so difficult to defeat.
Modern cars come with this security system by default. This makes it very difficult to wire a car or use a different key for starter. The system works by analyzing the chip inside the key fob or key and transmitting a passcode to the ECU (electronic control unit). The ECU is then able to determine that it's the correct key and that the code isn't compromised. The system won't allow the car to start if the doesn't have the correct code. Some models will even notify the owner if a person tries to use an unapproved key or fob.
The system isn't foolproof, however. Some thieves have managed to bypass the immobiliser using techniques like 'hot-wiring'. This involves crossing the wrong wires in the wiring of a vehicle to trick the ECU into thinking that the correct key or fob is being used. This is a risky technique and requires a lot of knowledge to avoid electrocuting oneself. Additionally, many modern car thieves have switched over to more advanced methods, such as using specialized apps or Bluetooth to take over the car's information and remotely control it using their phones.
Car owners are often faced with warning lights that indicate that the immobiliser has gone off the rails. This can occur for various reasons but the most frequent one is a malfunctioning battery in the keyfob. The issue can be solved by an easy replacement.

If any of these issues occur it's a good idea visit an auto garage or a local dealer for assistance.
