      i’ve heard of that being the standard for water valves but i don’t think it’s a universal thing for simple door locks

          if it still locks the door it’s fine then! Water valves need to be standardised as sometimes you need to know water’s not flowing, especially if it’s an emergancy, but a door lock? just check if it’s closed man
