Instead, the immobiliser is dependent on the transponder chip in the key or fob. This chip sends a passcode to the immobilizer unit of the car which can be integrated into the PCM, BCM, the instrument cluster smart junction box, or standalone module. The system then validates the code to make sure it is correct. If the code is incorrect the system will disable components that are essential to starting the car, like the ignition motor or starter motor. The car will be nearly impossible to start if you don't have the correct key.

It is also referred to a "chip key" or a "transmitter-responder" key. Its goal is to prevent your engine from starting when you have a duplicate of your key. It works by transmitting an audio frequency signal from the key to the immobiliser system inside your car. If the code on the car's computer is in line with the signal sent from the key, it will disarm the immobiliser and allow the engine to start.
The key that is equipped with a transponder chip is often referred to as"fob" or a 'smart' key because it is much more difficult to copy than a traditional mechanical key. With the help of specific methods, it is possible to duplicate a standard car key but not a transponder key. Transponder chips are powered by an infrared signal and not battery power.
To activate the transponder chip the ignition cylinder must be turned on. The ring emits IR energy which is detected by a microchip inside the key. The chip then sends a unique code to the immobiliser in your car. The car's computer compares the code stored in its memory to the transponder's and when the two codes match, it will start the engine.
The immobiliser will disable the engine if it detects an unauthorised transponder or key. It also stops all vital parts of the car from functioning.

This could be due to interference or an immobiliser that is too sensitive. This may need a reset. To do this, simply disconnect the battery. After 15 minutes, reconnect the battery and then restart the vehicle. This will reset the system and allow it to accept the key again.
The security light is a way of warning you of an issue. If the light is on and you try to start your car, it means that the code stored in the ECU is not compatible with the chip in the key. This can occur if your car key was replaced with a new one that is not programmed for the vehicle, or if the ECU has been swapped incorrectly.
If this is the case you should take your transponder or key chip to a professional to get them properly programmed for your vehicle. It is possible that the system will not accept the key due to a software update or bug. To test this, place your key in the ignition and turn it to ON but don't attempt to start the engine.

The system won't allow the vehicle to start if it doesn't receive the correct code, and some models will even inform the owner in the event that someone attempts to use an unapproved fob or key.
The system isn't impervious to attack, but it is. Certain thieves have been able to bypass the immobiliser using methods like hot-wiring. This involves crossing the wrong wires through the wiring of a vehicle, which fools the ECU into thinking the proper key or fob is being used. This is a risky technique and requires a lot of knowledge to avoid electrocuting oneself. Additionally, many modern car thieves have switched over to more advanced methods like using specialized apps or Bluetooth to steal the car's data and then remotely control it from their mobile.
Car owners often notice warning lights that signal an immobiliser malfunctioning. 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. This issue can be resolved by replacing the battery.
