The chip transmits a passcode to the immobilizer unit of the car that can be integrated into the PCM, BCM, instrument cluster smart junction box or standalone module.

It functions by sending an audio frequency signal from the key to the immobiliser system in your car. If the code stored in the car's computer is in line with the signal sent by the key the immobiliser will be disarmed and the engine will be able to start.

Using specific methods, it is possible to duplicate a standard car key, but not transponder keys. Contrary to the remote central locking element of a standard key which is powered by batteries, a transponder chip is powered by an infrared (IR) signal transmitted through the antenna ring on the ignition cylinder.

To activate the transponder chip the ignition cylinder needs to be turned to the ON position. The ring emits a burst IR energy which is received by a microchip in the key. The chip responds by sending a unique code to the immobiliser of your car.

This will reset the system and allow it to accept your key again.

The security light is an immobiliser's method of alerting you to a problem.

Modern cars come with this security system in the standard configuration. This makes it really hard to connect the car to a hot wire or use another key for starter. The system operates by sending a passcode from the key fob to the ECU. The ECU then knows that it's the right key and that the passcode hasn't been compromised. The system won't allow the car to start if it does not receive the correct code. Some models even notify the owner if they try to use an incorrect fob or key.

The system is not 100% secure, however. Some thieves have managed to bypass the immobiliser with techniques such as 'hot wiring.' This involves crossing the wrong wires through a vehicle's wiring to fool the ECU to believe that the correct key or fob is being used. This method is risky and requires extensive knowledge to avoid electrocuting oneself. In addition, many modern car thieves have shifted over to more advanced methods like using specialized apps or Bluetooth to take over the car's information and remotely control it using their phone.

Car owners will frequently be greeted by warning lights that indicate an immobiliser that has gone out of control. This could be due to a variety of reasons, but the most common one is a faulty battery in the keyfob. A simple replacement can fix the issue.
