The chip transmits a code from the key or fob to the immobilizer unit of the car, which can be integrated into the PCM (power control module) or BCM (brake control module for brake control), instrument clusters smart junction boxes or standalone modules. The system then checks the code to make sure it is correct. If the code is incorrect, the system disables elements that are crucial to starting the car, like the starter motor or ignition.

Also referred to as a 'chip key or a 'transmitter & responder key, it's designed to stop the engine from starting if a third party has the same key. It works by transmitting a radio frequency from the key to your immobiliser system. If the code in the car's computer matches the signal sent from the key, it will disable the immobiliser and allow the engine to start.

The key that is equipped with a transponder chip is often referred to as a 'fob' or a "smart" key because it is more difficult to duplicate than a traditional mechanical key. It is possible to duplicate a standard key but not a transponder key. In contrast to the remote car key repairs central locking element of a conventional key which uses battery power, a transponder chip is powered by the infrared (IR) signal transmitted by the antenna ring that is located 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 absorbed by the microchip within the key. The chip then sends a unique code to the immobiliser of your car. The computer in the car analyzes the code stored in its memory with the transponder's code and If the two codes are identical it will begin the engine.

The immobiliser will shut down the engine if it detects an unauthorized key or transponder. It also blocks any vital components of the car from functioning.

This could be due to interference or the system becoming too sensitive. If this is the situation, it may need to be reset. To do this, disconnect the battery. After 15 minutes, reinstall the battery and then restart 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 is an issue with the system. If you try to start your car and the light stays on it indicates that the chip inside your key isn't compatible with the code that is stored in the ECU.

Programming

An immobiliser for cars prevents the engine of a car from running without a properly programmed key or fob. It uses a special RFID micro-chip that can't be copied and has its own serial number. The immobiliser will stop working in the event that it doesn't recognize the code. That's why it's difficult to defeat.

Modern cars are fitted with this security system in the standard configuration. This makes it difficult to hot-wire a vehicle or use a different key as a starter. The system works by checking the chip in 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 isn't compromised. The system won't permit the car to start if it doesn't have the correct code, and some models will even notify the owner in the event that someone attempts to use an unapproved key or fob.

However it isn't completely secure. Some thieves have bypassed the immobiliser by using techniques like 'hot-wiring.' This involves crossing the wrong wires in a vehicle's wiring to fool the ECU into thinking that the appropriate fob or key is being used. This is a risky technique and requires a lot of experience to avoid electrocuting oneself. Modern car thieves are also employing more sophisticated methods such as Bluetooth or other specialized apps to obtain information about a vehicle and remotely control it remotely.
