A smart lock is an electronic and mechanical locking device that opens wirelessly with an authorized users’ authentication. In a smart home, smart locks allow a homeowner to enter their home or provide others access without requiring a traditional key. Instead, the user uses their smartphone or a key fob to wirelessly verify and mechanically unlock the door. Smart locks are an extension of home automation into home security. As a connected device, smart locks can be considered a part of the internet of things (IoT).
