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 will check the code to ensure it is correct. If the code is incorrect it will disable the components that are essential to start the car, such as the starter motor or ignition. This makes the car nearly impossible to start without the correct key.

If the issue continues to persist it could be due to other causes for the vehicle's irregular behavior, such as electrical issues or a wiring problem. It is recommended to have a professional identify the issue and then fix it.
Transponder Chip
In vehicles manufactured after 1995, a tiny electronic chip referred to 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 function is to stop your engine from starting if another person has the same key. It works by sending an audio signal from the key to your immobiliser system. If the code on the car's computer is in line with the signal transmitted by the key, it will disable the immobiliser and allow the engine to start.
The key that has the transponder chip can be referred to as"fob" or a "smart" key because it is much more difficult to clone than a traditional mechanical key. Using specific techniques, it is feasible to copy a conventional car key but not the transponder key. Contrary to the central locking element remote of a conventional key which is powered by batteries the transponder chip is powered by the infrared (IR) signal that is transmitted by the antenna ring that is located on the ignition cylinder.
To turn on the transponder, the ignition cylinder has to be in the ON position. The ring emits a burst IR energy that is detected by a microchip inside the key. The chip responds by sending 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 match the engine will begin to rev.
The immobiliser will disable the engine if it detects an unauthorised key or transponder. It also blocks all vital components of the vehicle from working. Without a functioning engine, the vehicle won't be able to move and it could be easy for criminals to wire the vehicle and drive away. This is a powerful deterrent against criminals and is one of the reasons why it's essential to have your car's key immobiliser fixed immediately you discover any issue with it. If you don't fix it, the security light on your car will keep flashing and it will be difficult for you to start your engine.
Security Light
The immobiliser is powered by a small battery that sends an electric signal to the transponder chip within your key. This device is designed to prevent anyone from starting the car without the correct keys. If the system is not able to recognize a digital serial from the chip on your key, it will shut off the engine immobiliser, which will stop the car starting.
The car immobiliser is an excellent method to deter thieves, however it can occasionally be out of 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. Leave it disconnected for about 15 minutes then reinsert it and start the car. This will reset the system and allow it to accept your key once more.
The security light is an immobiliser's way of alerting you to the presence of a problem. If you attempt to start your car and the light stays on, it means that the chip inside your key isn't in sync with the code stored in the ECU. This can occur when your car's key has been replaced by a new one that is not programmed for the vehicle, or if an ECU was not swapped correctly.
If this is the case, then you need to go to a professional for assistance and get the transponder or key chip properly programmed to your vehicle. It's possible that the system won't accept the key due to a software upgrade or glitch. To test this, insert your key in the ignition and then turn it to the ON position. Don't try to start the vehicle. The key should remain in this position for 10 minutes. This will cause the security light to turn on and to turn off. If it doesn't, you'll have to repeat the procedure and wait another 10 minutes. Repeat the process three times and the issue should be solved.
Programming
An immobiliser for cars prevents a car's engine from running without a key that is programmed correctly or fob. It makes use of a unique RFID microchip that cannot be copied and has its own digital serial number. The immobiliser will stop working in the event that it is unable to recognize the code. This is why it's so hard to beat.
Modern cars are fitted with this security system as standard. This makes it really hard to connect the car to a hot wire or use a different key as a starter. The system works by analyzing the chip in a key fob or a key and sending a passcode to the ECU (electronic control unit). The ECU is aware that it's the right key and hasn't been compromised code. The system will not allow the car to start if it does not receive the correct code. Certain models will even notify the owner if they try to use an incorrect fob or key.
However the system isn't impervious to theft. Some thieves have been able to bypass the immobiliser by using methods like hot-wiring. This involves crossing the wrong wiring in an automobile to fool the ECU. This is a risky method and requires a lot of knowledge to avoid electrocuting oneself. Plus, a lot of modern car thieves have moved to more sophisticated methods like using specialized apps or Bluetooth to steal the car's data and then remotely control it from their mobile.
Car owners often see warning lights that indicate an immobiliser that has gone out of control. This could be due to a variety of reasons, but one of the most frequent causes is due to a damaged or dead battery in the key fob. The issue can be solved by a simple replacement.
If this doesn't work it could be because the transponder chip is faulty or the ECU is mismatched. This is harder to determine and fix since it may require an expert locksmith or a dealership. However, a car immobiliser may also be damaged by water intrusion, or even being removed from the fob or key. If you experience any of these issues it is a great idea that you visit an auto dealer in your area or garage to seek help.
