Transponder Chip
A tiny electronic chip, also known as a transponder, is built into the head portion of your car keys. This technology was first introduced in cars made after 1995. Also known as a 'chip key' or a 'transmitter and responder key, it's created to stop the engine from starting if another person has an exact copy of your car key. It works by sending an audio signal from the key to your immobiliser system. If the code on the car's computer matches that signal sent from the key, it will disable the immobiliser and allow the engine to start.
The key with the transponder chip is sometimes called a 'fob' or a smart key due to the fact that it is more difficult to clone than a traditional mechanical key. With the help of specific techniques, it is feasible to duplicate a standard car key however, not transponder keys. Transponder chips are powered by an infrared signal not battery power.
To activate the transponder the ignition cylinder needs to be in the ON position. The ring emits a burst of IR energy, which is picked up by the microchip in the key. The chip responds by transmitting a unique code to your car's immobiliser. The car's computer compares the code stored in its memory with the transponder's code and when the two codes match it will begin the engine.
The immobiliser shuts down the engine if it detects an unauthorized key or transponder. It also blocks all vital components of the car from functioning.

If the system can't detect a digital serial number from the chip inside your key it will disengage the engine immobiliser and prevent the car from getting started.
The car immobiliser is a great way to deter thieves, however it can occasionally be out of in sync. This could be due interference or an immobiliser that is too sensitive. If this is the case it could be necessary to reset. To do this, just disconnect the battery. Then leave it off for around 15 minutes, then insert it and begin the vehicle. This will reset the system and make it ready to accept your key again.
The security light is the car immobiliser's method of letting you know that there's an issue with the system. If the light is illuminated and you attempt to start your car, it is a sign that the code that is stored in the ECU does not match the chip on the key. This can happen if your car key was replaced with an alternative key that is not compatible with the vehicle, or if the ECU was swapped in a wrong manner.
If this is the situation, then it's time to talk to a professional to have the the transponder chip properly programmed to your vehicle.

Programming
A car immobiliser prevents the engine of a car from running without a properly programmed key or fob. It uses a special RFID chip that cannot be duplicated and has a unique digital serial number. The immobiliser will be disengaged in the event that it doesn't recognize the code. This is why it's so hard to defeat.
Modern cars come with this security system in the standard configuration. This makes it really hard to wire the car hot or use another key for starter. The system works by sending a code from the key fob to the ECU. The ECU recognizes that it is the correct key and that there hasn't been a compromise in the code. The system will not allow the car to start in the event that it does not receive the correct code. Certain models will even notify the owner if they try to use a wrong fob or key.
The system isn't foolproof, however. Some thieves have managed to bypass the immobiliser by using methods such as 'hot-wiring'. This involves crossing the wrong wires in the wiring of a vehicle, which fools the ECU into thinking the proper key or fob is being used. However, this is quite risky and requires a lot of knowledge of how to accomplish it without damaging yourself. In addition, many modern car thieves have shifted to more sophisticated methods, such as using specialized apps or Bluetooth to hijack the car's data and then remotely control it via their phones.
Owners of cars will often see warning lights that indicate an immobiliser that has gone out of control. This could be due to a variety of reasons, but the most common is due to a damaged or dead battery on the key fob. The issue can be solved by an easy replacement.
