Also referred to as a 'chip key or online a 'transmitter & responder key, it is created to stop the engine from starting if a third party has an exact copy of your car key. It functions by sending a radio frequency signal from the key to the immobiliser system of your car. If the code stored in the computer of the car is in line with the signal sent by the key, the immobiliser will be disarmed and the engine will start.
The key repairs that is equipped with a transponder chip is sometimes called"fob" or a smart key because it is much more difficult to copy than a conventional mechanical key. Utilizing specific techniques, it is feasible to copy a conventional car key but not transponder keys. Unlike the central locking element remote of a conventional key which uses battery power, a transponder chip is powered by an infrared (IR) signal that is transmitted through the antenna ring on the ignition cylinder.
To turn on the transponder, the ignition cylinder must be in the ON position. The ring emits a burst IR energy that is detected by a microchip within the key. The chip responds by sending a unique code to the immobiliser in your car. The car's computer compared the code stored in its memory to the one from the transponder chip and if they match the engine will be able to start.
The immobiliser shuts down the engine in the event of an unauthorised key or transponder. It also stops all vital components of the car keys repairs from functioning. Without a functioning engine the vehicle won't be able to move, and it would be very easy for a criminal to connect the vehicle to a hot wire and then drive away.

If you don't do this, the security light on your vehicle will continue flashing and you will not be able to start it.
Security Light
The immobiliser is powered by a tiny battery that sends an electric signal to the transponder chip inside your key. This anti-theft device prevents anyone from starting their car without the correct keys. If the system cannot detect a digital serial from the chip on your key, it will shut off the engine immobiliser to stop the car from starting.
The car immobiliser is a great way to deter thieves, but it can sometimes be out of in sync. This can be caused by interference or the system becoming too sensitive. If this is the case, it might need to be reset. To do this, simply disconnect the battery. Leave it disconnected for about 15 minutes, then insert it and start the car. This will reset the key system to ensure that it is ready to accept your keys again.
The security light is the vehicle immobiliser's method of letting you know that there is an issue with the system. If you attempt to start the car and the light stays on, it means that the chip in your key isn't in sync with the code stored in the ECU. This could happen if you have recently replaced your car's key with another that was not programmed to the vehicle, or when you've had a damaged swapped ECU.
If this is the case, then it's time to talk to a professional to have the the transponder chip properly programmed to your vehicle. It's possible that the system won't accept the key because of a software update or bug. To test, insert your key in the ignition and turn it to the ON position. Don't try to start the vehicle. The key should remain in this position for 10 minutes. This should cause the security lights to come on and then to go off.

Programming
A car immobiliser prevents the car's engine from operating without a key that is programmed correctly or fob. It is based on a specific RFID microchip that cannot be duplicated and comes with its own digital serial number. The immobiliser will be disconnected in the event that it is unable to recognize the code. It's hard to beat.
Modern cars have this system as standard. This makes it very difficult to connect the car to a hot wire or use a different key for starter. The system works by sending a code from the key fob to the ECU. The ECU knows it's the correct key and hasn't been a compromise in the code. The system won't permit the car to start if it does not receive the correct code, and some models will even inform the owner if a person tries to use an unapproved fob or key.
However, the system is not foolproof. Some thieves have managed to bypass the immobiliser by using techniques such as 'hot wiring.' This involves crossing the wrong wiring in an automobile to cause a malfunction in the ECU. But, this technique is pretty risky and requires a lot of experience to accomplish it without electrocuting yourself. Plus, a lot of modern car thieves have moved to more sophisticated methods, such as using specialized apps or Bluetooth to steal the car's data and then remotely control it via their mobile.
Car owners will frequently notice warning lights that signal an immobiliser that has gone out of control. This could be due to a variety of reasons, but one of the most frequent is a faulty or dead battery in the key fob. A simple replacement should fix this problem.
If this does not work, it could be that the transponder chip is faulty or the ECU is not matched. This is more difficult to fix and diagnose as it may require a specialist locksmith or dealership. However, a car immobiliser can be damaged by water intrusion, or even being removed from the fob or key. If you encounter any of these problems it is a great idea to consult a local car dealer or garage to seek help.
