Some models also have a remote system that allows you to start the engine and close the sunroof and windows from the distance. These advanced keys use radios for locking and unlocking as well as infrared (IR) to communicate with the dashboard.

The IR circuit powers a bidirectional infrared bridge which sends commands from and to the dashboard, and also to the receptacle inside the key. This allows the key to control the car from just a couple of meters away. The key has an RF coil that detects and transmits the remote signal for locking from the car to the dashboard.
