The thing called an "Airlock" in ONI is not an airlock! It's just a single sealable door that is gas-impermeable.
In the real world, an airlock comprises two airtight doors which are never open simultaneously; it maintains pressure and minimizes gas exchange between opposite sides.
So please either rename Manual Airlock to "Sealing Door" (or "Airtight Door" or "Metal Door" or just "Door"), or make it work like a proper airlock. And likewise for Mechanized Airlock -> Mechanized Door (or Automated Door or whatever).
FYI the "lock" in airlock does not refer to a latch; instead it's the sense of a water lock, like in a canal.
