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

Its goal is to stop the engine from starting when you have a duplicate of your key. It functions by sending a radio frequency signal from the key to the immobiliser system inside your car. If the code stored in the car's computer matches the signal sent by the key the immobiliser will then be deactivated and the engine will be able to start.
The key that has 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 a mechanical key. With the help of special techniques, it is feasible to copy a conventional car key but not the transponder key. In contrast to the remote central locking element of a conventional key which is powered by batteries the transponder chip is powered by the infrared (IR) signal transmitted through the antenna ring on the ignition cylinder.
To activate the transponder the ignition cylinder has to be in the ON position. The ring emits a blast of IR energy, which is picked up by the microchip inside 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 that from the transponder chip, and when they here match, the engine will start.
If the immobiliser is able to detect an unauthorised transponder or key is in use it will shut down the engine and stop any of its vital components from working.

If the system cannot identify a digital serial number from the chip inside your key, it will deactivate the engine immobiliser, preventing the car from beginning.
The car immobiliser is an excellent method of deterring thieves, however it can sometimes be out of in sync. This could be due to interference or the system is too sensitive. This may need the system to be reset. To do this, just disconnect the battery. After 15 minutes, reconnect the battery and restart the vehicle. This will reset the system check here and allow it to accept the key again.
The security light is an immobiliser's way of alerting you to a problem. If the light is on and website you try to start your car, it means that the code stored in the ECU is not compatible with the chip on the key. This can happen if you have recently replaced the car key with one that has not been programmed to your vehicle or in the event that you've had a defective swapped ECU.
If this is the situation it is recommended to take your key or transponder chip to a professional to have them correctly programmed for the vehicle you are driving.

That's why it's so difficult to defeat.
Modern cars come with this security system as standard. This makes it very difficult to check here hot-wire a vehicle or use a different key for starter. The system works by sending a passcode from the key fob to the ECU. The ECU will then verify that it's the right key and that the passcode isn't compromised. The system will not allow the car to start in the event that it does not receive the correct code. Some models even notify the owner if they attempt to use an unapproved fob or key.
The system isn't foolproof, however. Some thieves have managed to bypass the immobiliser using methods such as 'hot-wiring.' This involves crossing the wrong wire in an automobile to cause a malfunction in the ECU. But, this technique is quite risky and requires a lot of experience to carry out the procedure without cutting yourself. Modern car thieves are also employing more sophisticated methods, such as Bluetooth or other apps that steal a car's information and remotely manage it.
Owners of cars will often see warning lights that indicate an immobiliser malfunctioning. This could be due to many reasons however the most common reason is a defective battery in the keyfob. A simple repair should resolve this issue.
