The M1 is a keypad door knob that unlocks with a passcode or a physical key, then relocks itself 5 seconds after use. It holds up to 100 codes managed from one admin code, with Passage Mode and Silent Mode, and its anti-peep scramble lets you type random digits around your real code. Zinc alloy construction and a water-resistant rating suit rentals, offices and dorms. Against app-connected smart locks it is simpler and cheaper to run, but it has no Bluetooth, Wi-Fi or remote access, so codes must be set at the door.
