Key 2.0 is a Bluetooth IoT Door Lock. It turns a conventional electric door lock into a smart door lock that can be opened using a smartphone without the need for a physical key. Thus, Key20 is the modern version of a physical key, or, as the name suggests, the key version 2.0 for the Internet of Things (IoT) era.
