Following a 2015 crowdfunding campaign Friday Labs launches the Friday Lock-- a smart lock promising to be the "smallest and most stylish" retrofit option.
The Friday Lock features Bluetooth, wifi and HomeKit connectivity, and comes in a slender package in a range of finishes. The minimalist design lacks a display or any features making it look like a smart device, and interchangeable die cast metal shells fit with the rest of the house or room.
Installation involves a Friday Universal Baseplate the makers say requires no locksmith, while a Door Adapter Plate ensures a secure fit on doors needing longer tailpieces. The smart lock is powered with a battery able to run for up to 3 months between charges (via included USB charger).
