key20

by duerrfk

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.

Repository topics

Every project listed here belongs to its author and is linked to its original repository. Licences are read from the repository metadata and summarised for convenience — check the licence file in the project itself before you manufacture or redistribute a design. ProtoFlow does not host, mirror or verify these files. Index last rebuilt 2026-09-21.
