This chip sends a passcode 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 then verifies the code to ensure that it is correct. If it is not, the system will disable components crucial to starting the vehicle, such as the ignition or starter motor. The car will be impossible to start if you don't have the correct key.
Since its inception the immobiliser has proven to be an extremely effective tool in reducing car theft. Even so thieves are always seeking ways to bypass these security measures.

A dying or dead keyfob battery is typically the cause of a malfunctioning ignition immobiliser. A quick diagnostic test could identify the issue. If the issue continues to persist it could be due to other causes of the car's irregular behavior, such as electrical issues or a wiring issue. It is recommended to let a professional identify the issue and then fix it.
Transponder Chip
In cars manufactured after 1995, a small electronic chip referred to transponder is embedded in the head of your car key. It is also referred to a "chip key" or a "transmitter-responder" key. Its purpose is to stop the engine from starting when you have a duplicate of your key. It works by transmitting a radio frequency from the key to your immobiliser system. If the code stored in the car's computer matches the signal transmitted by the key the immobiliser will be removed and the engine will be able to start.
The key with a transponder can also be referred to as a "fob" or a "smart" key due to the fact that it is more difficult to copy than mechanical keys. Utilizing specific techniques, it is possible to copy a conventional car key however, not the transponder key. Contrary to the remote central locking element of a standard key which uses battery power the transponder chip is powered by an infrared (IR) signal that is transmitted through the antenna ring on the ignition cylinder.
To activate the transponder the ignition cylinder needs to be in the ON position. The ring emits a flash of IR energy, which is detected by the microchip inside the key. The chip then sends an individual code to the immobiliser of your car. The car's computer compared the code in its memory with the one from the transponder chip and if they match the engine will be able to start.
The immobiliser will disable the engine in the event of an unauthorised key or transponder. It also blocks any essential components of the car from working. The car will not move if the engine is not working. It is easy for a criminal to hot-wire it to drive away. This is an effective security measure against crime, and is the reason why you should get your car key-immobiliser repaired as quickly as possible if it develops a fault. If you don't do this, 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 makes use of a tiny battery to send an electrical signal to the chip inside your key. It is an anti-theft device that stops anyone from driving your car without the proper key. If the system is unable to detect an electronic serial number from the chip in your key, it will shut off the engine immobiliser to prevent the car from starting.
The car immobiliser system is an an effective way to stop thieves, however it can become out of in sync with the key or transponder chip. This could be due to interference or the system being too sensitive. If this is the situation, it could be necessary to 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 key system so that it is ready to accept your keys again.
The security light is an immobiliser's method of warning you of an issue. If the light is on when you attempt to start your car, it is a sign that the code stored in the ECU is not compatible with the chip in the key. This could happen in the event that your car's key was replaced with a new one that is not programmed to work with the vehicle, or if the ECU was not swapped correctly.
If this is the case you should take your transponder or key chip to a professional for them properly programmed for your vehicle. There is also the possibility that the system isn't accepting the key due to 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. The key should remain in this position for ten minutes. This should cause the security light to light up and then to go off. If it doesn't work, you'll need to repeat the procedure and wait another 10 minutes. Repeat the process three times and the issue is likely to be solved.
Programming
The car immobiliser blocks the engine from running if the fob or key is not properly programmed. It uses a special RFID microchip that isn't able to be copied and has its own digital serial number. The immobiliser will disconnect when it doesn't recognize the code. This is why it's so hard to beat.
Modern cars have this system as standard. This makes it very difficult to wire a car or use a different key as a starter. The system works 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 won't allow the car to begin when it doesn't receive the correct code. Certain models will even notify the owner when they attempt to use a wrong fob or key.
The system isn't 100% secure, however. Some thieves have managed to get around the immobiliser using techniques like 'hot-wiring'. This involves crossing the wrong wire in a vehicle in order to cause a malfunction in the ECU. However, this is pretty risky and requires a great deal of experience to accomplish it without cutting yourself. In addition, many modern car thieves have switched over to more advanced methods, such as using specialized apps or Bluetooth to steal a car's data and remotely control it via their phones.
Car owners will often get warning lights that indicate that the immobiliser is malfunctioning. It can happen for various reasons, but the most common reason is a defective battery in the keyfob. This problem can be fixed by replacing the battery.
If this isn't working the transponder chip could be defective or mismatched with the ECU. This is more complicated to diagnose and fix because it requires a specialist locksmith for cars or a dealership. However, a car's immobiliser can also be damaged by water intrusion, or even being pulled away from the fob or key. If any of these problems occur, it's recommended to visit a local garage or car dealer to seek assistance.
