The Airlocks in Artemis and the Apollo 11 Visitor's Center can only be operated by an EVA master from the EVA Guild. Whilst on the inside only an EVA master's Gizmo can unlock the airlocks but from the outside, for safety reasons, it is not required to have a Gizmo and it can be opened by anyone.
The airlocks contain emergency oxygen supplies for anyone who has a leaky suit upon re-entry of Artemis that is refilled by someone from the city.
