Detect if player is in structure (or in range)

Hi. I am creating a video game called “Kianate”, which is for space exploration, and the Beta version is suppost to be run by the arrow keys & wasd, for pc. WASD will control the player, arrow keys control the ship. I need to find a way to make it so that the arrow keys only work when the player is inside the ship’s bridge. I need to find a way to detect if the playerobject is in the ship_bridge object. I could do that by figuring if its in the structure, or just in range of the rooms chandelier. is there any way to do this?

The simplest way would be to put a collider around the room or colliders at the points of entry to the room and use OnTriggerEnter to enable the arrow keys when the player enters the room/collider. And then it disables the arrow keys on exit.
