Nova Keypad Lock K1

The K1 retrofits over the lock you already have and adds a backlit keypad to the outside. Codes are handed out in the app and can be permanent, one-off or valid for a window of your choosing, and every entry is logged with a name rather than a number. The keypad wakes on approach, hides fingerprints behind a random-digit prefix, and falls back to a physical key that stays in the drawer for the day the batteries do run out.
