The chip transmits a passcode to the car's immobilizer device, which may be built into the PCM, BCM or instrument cluster smart junction box, or standalone module. The system examines the code to ensure it is correct. If the code is incorrect it will disable the elements that are crucial to start the car, like the ignition or starter motor. 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 in reducing the theft of cars.

Transponder Chip
A small electronic chip, referred to as a transponder, is built into 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 someone else has an exact copy of your car key. It works by transmitting 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 disarmed and the engine will start.
The key that has the transponder chip can be referred to as a 'fob' or a smart key due to the fact that it is more difficult to duplicate than a conventional mechanical key. With the help of special techniques, it is possible to copy a standard car key, but not a transponder key. Contrary to the central locking element remote of a standard key that relies on battery power, a transponder chip is powered by an infrared (IR) signal transmitted through the antenna ring on the ignition cylinder.
To activate the transponder chip the ignition cylinder must be turned on. The ring emits a flash of IR energy which is picked up by the microchip in the key. The chip responds by transmitting a unique code to the immobiliser of your car. The car's computer checks the code stored in its memory to the one from the transponder chip, and If they are compatible, the engine will start.
The immobiliser will disable the engine when it detects an unauthorised key or transponder. It will also prevent any essential parts of the car from working. Without a functioning engine the car will not be able to move and it would be very easy for a criminal to wire the vehicle and then drive off.

If you don't, the security light in your car will continue to flash and it will be inaccessible for you to start your engine.
Security Light
The immobiliser is powered by a tiny battery that sends an electrical signal to the transponder chip within your key. This anti-theft device prevents anyone from starting their car without the correct keys. If the system cannot detect an electronic 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 get out of connection with the key or transponder chip. This can be due to interference or the system being too sensitive. If this is the situation, it might need to be reset. To do this, simply disconnect the battery. After 15 minutes, you can reinstall the battery and then restart the vehicle. This will reset the system and allow it to accept the key again.
The security light is the car immobiliser's way of telling you that there's an issue with the system. If the light is illuminated and you try to start your vehicle, it indicates that the code stored in the ECU is not compatible with 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 for the vehicle, or if the ECU has been swapped incorrectly.
If this is the situation, then you need to go to a professional to have the transponder or key chip properly programmed to your vehicle. There is also the possibility that the system is not accepting the key because of a software bug or update. To test this, place your key in the ignition and switch it to ON but don't attempt to start the engine. Keep the key in this position for ten minutes. This should cause the security lights to light up and then to turn off. If it doesn't then you'll need to repeat the process and wait for another 10 minutes. This should solve the problem If you repeat the procedure three times.
Programming
The car immobiliser prevents the engine from running if the fob or key are not properly programmed. It uses a special RFID chip that cannot be duplicated and has a unique digital serial number. The immobiliser will be disconnected in the event that it is unable to recognize the code. It's tough to beat.
Modern cars have this system as standard. This makes it extremely difficult to wire the car hot or use another key for starter. The system operates by sending a passcode from the key fob to the ECU. The ECU recognizes that it is the correct key and that it doesn't have to be compromised code. The system will not allow the car to start when it doesn't receive the correct code. Some models even notify the owner if they try to use an incorrect fob or key.
However it isn't impervious to theft. Some thieves have managed to get around the immobiliser using methods like hot-wiring. This involves crossing the wrong wiring in an automobile to cause a malfunction in the ECU. This method is risky and requires a lot of experience to avoid electrocuting oneself. Plus, a lot of modern car thieves have moved to more sophisticated methods such as using specialised apps or Bluetooth to steal the car's data and then remotely control it via their phone.
Car owners often see warning lights that indicate an immobiliser gone haywire. This can happen for various reasons, but the most frequent is due to a damaged or dead battery in the key fob. The issue can be solved by a simple replacement.
If this isn't working the transponder chip could be defective or mismatched with the ECU. It is more difficult to fix and diagnose, as it can involve a specialist locksmith for cars or a dealership. However, a car immobiliser may also be damaged by water intrusion or even being pulled away from the fob or key.
