These keys feature radio for locking / unlocking and infrared (IR) to communicate with the dashboard.

The IR circuit creates a bidirectional infrared bridge which sends commands to and from the dashboard and to the receptacle in the key. This lets the key control the car from a couple of meters away. The key also comes with an RF coil that detects the remote lock signal from the car and transmits it to the dashboard.

Modern smart keys, as opposed to older car keys that transmit the same frequency continuously (which could impact cars that use the same system, making it easier for criminals with tech skills to take cars) they transmit a different encrypted message each time they are used to open or close the door or to open the trunk. The vehicle's embedded antennas then respond by generating a corresponding frequency to identify the key and allow it to unlock or turn it on.

Hacking is possible but not impossible. A skilled professional can intercept the IR transmissions and gain access to your vehicle.
