It can be integrated into the PCM (power control module) BCM (brake control module), instrument cluster, smart junction boxes, or standalone modules. The system checks the code to ensure that it is correct. If the code isn't correct, the system disables components that are crucial to starting the car, such as the starter motor or ignition. The car will be impossible to start if the driver doesn't have the correct key.
Since its introduction, the immobiliser has been an extremely effective tool in reducing car theft. However, thieves are constantly seeking ways to bypass these security measures. One of these is the Kia Challenge trend on TikTok, which shows how easy it can be to hot-wire an automobile.

It works by sending a radio frequency from the key to your immobiliser. If the code stored in the computer of the car is in line with the signal sent by the key the immobiliser will be deactivated and the engine will start.
The key that has the transponder chip is often referred to as"fob" or a "smart" key because it is more difficult to duplicate than a conventional mechanical key. It is possible to duplicate a conventional key but not a transponder one. Unlike the remote central locking element of a conventional key which uses battery power, a transponder chip powered by the infrared (IR) signal transmitted by the antenna ring on the ignition cylinder.
To activate the transponder chip the ignition cylinder has to be turned on. The ring emits a blast of IR energy that is absorbed by the microchip inside the key. The chip then responds with an individual code to the immobiliser in your car. The car's computer compares the code in its memory with that from the transponder chip and when they match the engine will be able to start.
If the immobiliser is able to detect an unauthorised transponder, key or other device is in use, it will disable the engine and prevent any of its essential components from functioning. Without a functioning engine, the car will not be able to move and it will be easy for criminals to hot-wire the vehicle and then drive away.

This will reset the key system to ensure that it is ready to accept your keys once again.
The security light is the vehicle immobiliser's method of letting you know that there's a problem with the system. If you attempt to start the car and the light stays on, it indicates that the chip in your key doesn't match the code that is stored in the ECU. This can happen when your car's key was replaced with a new key that's not programmed to work with the vehicle, or when an ECU was how to repair car key lock swapped in a wrong manner.
If this is the case then you need to go to a professional for assistance and get the the transponder chip properly programmed to your vehicle.

It's difficult to beat.
Modern cars are fitted with this security system by default. This makes it extremely difficult to hot-wire a vehicle or use a different key as a starter. The system works by checking the chip in a key fob or key, and sending a passcode to the ECU (electronic control unit). The ECU knows it's the correct key and hasn't been compromised code. The system will not allow the vehicle to start if it doesn't receive the correct code. Some models will even inform the owner if a person tries to use an incorrect key or fob.
The system isn't impervious to attack, but it is. Some thieves have managed to bypass the immobiliser using methods such as 'hot wiring.' This involves crossing the wrong wires through a vehicle's wiring to fool the ECU into thinking the appropriate fob or key is being used. However, this is extremely risky and requires a lot of knowledge of how to accomplish it without electrocuting yourself. Modern car thieves are also employing more sophisticated methods, like Bluetooth or other specialized apps to take over a car's data and remotely control it remotely.
Car owners will frequently be greeted by warning lights that indicate an immobiliser that has gone out of control. This could be due to various reasons, but the most common one is a faulty battery in the keyfob. The issue can be solved by an easy replacement.
