The chip transmits a passcode to the immobilizer unit of the car that can be integrated into the PCM, motor BCM or instrument cluster smart junction box or standalone module. The system will check the code to make sure that it is correct. If it's not, the system will disable parts that are essential to start the vehicle, such as the ignition or starter motor.

Since its inception the immobiliser has proven to be an extremely effective tool in decreasing car theft. However, thieves are constantly looking for ways to circumvent these security measures.

Transponder Chip
A small electronic chip, also known as a transponder, is built in the head of your car keys. The technology was introduced in vehicles manufactured after 1995. Also known as a 'chip key' or a 'transmitter and responder' key, it is designed to stop the engine from starting if someone else has a copy of your car key. It works by sending an audio signal from the key to your immobiliser. If the code stored in the car's computer matches the signal transmitted by the key, the immobiliser will be deactivated and the engine will begin to run.
The key that has the transponder chip is sometimes called"fob" or a "smart" key due to the fact that it is more difficult to copy than a conventional mechanical key. It is possible to duplicate a conventional key, but not a transponder key. In contrast to the central locking element remote of a conventional key that relies on battery power, a transponder chip powered by the infrared (IR) signal that is transmitted by the antenna ring on the ignition cylinder.
To activate the transponder the ignition cylinder must be in the ON position. The ring emits a flash of IR energy which is detected by the microchip in the key. The chip responds by sending a unique code to your car's immobiliser. The car's computer checks the code stored in its memory to the one from the transponder chip and when they match the engine will be able to start.
If the immobiliser detects an unauthorised transponder or key is in use, it will disable the engine and block any of its vital components from functioning. Without a functioning engine, the vehicle will not be able to move, and it would be very easy for criminals to hot-wire the vehicle and then drive away. This is a powerful way to deter criminals and is one of the reasons why it is essential to get your car's key immobiliser repaired when you spot a fault with it. If you don't take this action, the security light on your car will continue blinking, and you won't be able to begin it.
Security Light
The immobiliser is powered by a tiny battery that sends an electrical signal to the transponder chip inside your key. This anti-theft device prevents anyone from starting their car without the proper keys. If the system cannot detect a digital serial number from the chip in your key, it will disable the engine immobiliser and prevent the car from getting started.
The car immobiliser system is an effective in stopping thieves, but it is also possible for it to get out of sync with the key or transponder chip. This can be due to interference or a system that is too sensitive. This may need a reset. To do this, disconnect the battery. Then leave it off for around 15 minutes, then insert it and start the vehicle. This will reset the key system, so that it is ready to accept your keys again.
The security light is an immobiliser's 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 in your key doesn't match the code stored in the ECU. This could happen when your car's key has been replaced by a new key that's not compatible with the vehicle, or if the ECU has been swapped incorrectly.
If this is the case, then it's time to talk to a professional and have the transponder or key chip properly programmed to your vehicle. It is possible that the system won't accept the key because of a software update or bug. To test this, insert your key into the ignition and turn the ON position. Do not try to start the vehicle. Keep the key in this position for 10 minutes. This will cause the security light to turn on and motor to go off. If it doesn't work, you'll have to repeat the process and wait for another 10 minutes. Repeat this three times and the issue is likely to be solved.
Programming
The car immobiliser prevents the engine from running when a key or fob is not programmed correctly. It uses a special RFID micro-chip that can't be duplicated and has its own serial number. The immobiliser will disconnect in the event that it is unable to recognize the code. That's why it's difficult to defeat.
Modern cars come with this system as standard. This makes it very difficult to wire the car hot or use a different key as a starter. The system works by analyzing the chip in a key fob or a key and transmitting a passcode to the ECU (electronic control unit). The ECU is aware that it's the right key and that there hasn't be compromised code. The system will not allow the vehicle to start if it does not receive the correct code. Some models will even notify the owner if a person tries to use an incorrect fob or key.
The system is not foolproof, however. Some thieves have gotten around the immobiliser using methods like 'hot-wiring.' This involves using the wrong wiring in a vehicle in order to trick the ECU. But, this technique is pretty risky and requires a lot of experience to carry out the procedure without cutting yourself. Plus, a lot of modern car thieves have shifted to more sophisticated methods, such as using specialized apps or Bluetooth to take over a car's data and remotely control it from their phones.
Car owners will often get warning lights that signal that the immobiliser has gone haywire. This could be due to a variety of reasons, but the most common 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 might be faulty or mismatched with the ECU. This is harder to fix and diagnose as it may require an expert locksmith or a dealership. However, a car's immobiliser may be damaged by water ingress or even physically being pulled away from the fob or key. If any of these problems occur, it's a good idea to visit a local garage or car dealer for assistance.
