Instead, the immobiliser depends on the transponder chip located in the key or fob. The chip transmits a code from the key or fob to the immobilizer unit of the car. It can be integrated into the PCM (power control module) BCM (brake control module), instrument cluster smart junction boxes or standalone modules. The system then validates the code to make sure it is correct. If the code is not correct it will disable the components that are essential to the start of the car, such as the starter motor or ignition. This will make the car almost impossible to start if you don't have the right key.

It works by sending a radio frequency signal from the key to the immobiliser system in your car. If the code on the car's computer matches that signal from the key, it will deactivate the immobiliser and allow the engine to begin.
The key that is equipped with a transponder chip is often referred to as a 'fob' or a "smart" key due to the fact that it is more difficult to duplicate than a traditional mechanical key. Using special techniques, it is feasible to duplicate a standard car remote key repair key but not a transponder key. Unlike the central locking element remote of a conventional key, which is powered by batteries the transponder chip is powered by the infrared (IR) signal transmitted by the antenna ring on the ignition cylinder.
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 inside the key. The chip then sends an unique code to the immobiliser in your car. The car's computer compares the code stored in its memory to the transponder's and If the two codes are identical, it will start the engine.
If the immobiliser detects that an unauthorized transponder or key is in use, it will disable the engine and block the essential components from working. The car won't move when the engine isn't functioning. It is easy for a criminal to hot-wire it to drive away. This is a powerful way to deter crime, and is one of the main reasons why it's essential to have your car key immobiliser repaired when you spot an issue. If you don't take this action and the security light on your vehicle will continue flashing and you will not be able to begin it.
Security Light
The immobiliser is powered by a tiny battery that sends an electrical signal to the transponder chip in your key. It is an anti-theft device that prevents anyone from opening your vehicle without the right key. If the system can't detect a serial number digital from the chip in your key it will disengage the engine immobiliser and stop the car from getting started.
The car immobiliser system is an an effective way to stop thieves, however it can get out of connection with the key or the transponder chip. This could be due interference or an immobiliser that is too sensitive. This could require an adjustment. To do this simply disconnect the battery. Then leave it off for around 15 minutes before reinstalling it and begin the vehicle. This will reset the system and make it ready to accept your key again.
The security light is the vehicle immobiliser's way of telling you that there's an issue with the system. If you attempt to start your car and the light stays on, it means that the chip inside your key doesn't match the code stored in the ECU. This could happen if you have recently replaced the car key with another that has not been programmed to the vehicle or when you've had a damaged swapped ECU.
If this is the case then you need to go to a professional to have the key or the transponder chip properly programmed to your vehicle. There is also the possibility that the system is not accepting the key due to an issue with the software or an update. To test this, place your key in the ignition and switch it to ON but don't attempt to start the engine. Let the key stay in this position for 10 minutes.

Programming
An immobiliser for cars prevents the engine of a car from running without a correctly programmed key or fob. It is a unique RFID chip that is unable to be copied and is equipped with a digital serial number. The immobiliser will be disconnected if it does not recognise the code. That's why it's difficult to beat.
Modern cars are fitted with this security system as standard. This makes it really hard to wire the emergency car key repair hot or use another key for starter. The system works by analyzing the chip inside the key fob or key and sending a passcode to the ECU (electronic control unit). The ECU will then verify that it's the right key and that the passcode hasn't been compromised. The system will not allow the vehicle to start if it does not receive the correct code. Some models will even inform the owner if someone tries to use an unapproved key or fob.
However the system isn't completely secure. Some thieves have bypassed the immobiliser with techniques such as 'hot wiring.' This involves crossing the wrong wires in the wiring of a vehicle, which fools the ECU to believe that the correct key or fob is being used. However, this is pretty dangerous and requires a lot of experience to accomplish it without damaging yourself. Modern car thieves are using more advanced methods, like Bluetooth or other specialized apps to steal a car's information and remotely control it remotely.
Car owners often see warning lights that indicate an immobiliser gone haywire. This could be due to a variety of reasons, but the most common is a faulty or dead battery in the key fob. A simple replacement should fix this issue.
If this doesn't work, it could be that the transponder chip is defective or the ECU is mismatched. This is more complicated to diagnose and fix and may require an expert car locksmith or dealership.

If you experience any of these problems it is a good idea to consult an auto dealer in your area or garage for assistance.
