This chip transmits a passcode from the key or fob to the immobilizer module of the car, which can be integrated into the PCM (power control module), BCM (brake control module for brake control) instrument cluster smart junction boxes or standalone modules.

It works by transmitting radio signals from the key to your immobiliser system. If the code in the car's computer matches the signal transmitted by the key, it will deactivate the immobiliser and allow the engine to begin.

The key with a transponder can also be referred to as a "fob" or a "smart" key due to the fact that it is more difficult to duplicate than mechanical keys. It is possible to duplicate a conventional key, but not a transponder one. Transponder chips are powered by an infrared signal, not battery power.

The ring emits a burst IR energy that is picked up by a microchip within the key.  car key fob repair  sends a unique code to the immobiliser in your car. The car's computer analyzes the code stored in its memory with the transponder's and when the two codes match it will start the engine.

The security light is an immobiliser's method of warning you of an issue. If you try to start your car and the light stays on, it indicates that the chip in your key isn't compatible with the code stored in the ECU. This can happen if you have recently replaced the car key with a different one that was not programmed to the vehicle or if you've had a bad swapped ECU.

The system will not allow the car to begin in the event that it does not receive the correct code. Certain models will even notify the owner when they attempt to use a wrong fob or key.

However the system isn't impervious to theft. Some thieves have gotten around the immobiliser with techniques such as 'hot wiring.' This involves crossing the wrong wires in the wiring of a vehicle, which fools the ECU into thinking that the proper key or fob is being used. This is a risky technique and requires a lot of expertise to avoid electrocuting yourself. Modern car thieves are employing more sophisticated methods, like Bluetooth or other specialized apps to obtain information about a vehicle and remotely manage it.
