Smart Keys
Contrary to the conventional single piece of carved metal, smart keys use radio-frequency identification, or RFID to connect with the car.

Certain smart keys come with specific features, like saving preferences for drivers and opening windows remotely, or the sunroof from afar, and many more. These features can be accessed by activating the proximity sensor on the key fob, pressing a button or, in certain instances you can do this by twisting a small piece of metal inside the key.
Certain key fobs can be opened by placing the dead key in a slot, or by placing it near an inductive coil on the dashboard. Some even come with an emergency (fully mechanical) key blade hidden in the key to allow this.
