Our take on the KS03 Keypad Door Knob Lock

The KS03 is a battery-powered keypad knob lock from Veise with 20 user codes, a one-time code and two backup keys. It installs with a screwdriver on standard US doors and adds auto-lock, passage mode and an anti-peep keypad. It is a basic Grade 3 lock, so it suits bedrooms, back doors, rentals and offices rather than a main entry that needs a deadbolt. Against smart locks it trades app and Wi-Fi control for simple, offline keypad access and long AA battery life.
