The Trench Towers key

Eight doors on the wiki, two markers on our map

Per the wiki, the key opens 8 locked doors at the Trench Towers, and each tower has 2 doors on the first floor and 2 on the second floor. Our map has two door markers for the key, so read them as where the towers are, not as a count of doors.

Celeste's quests

Celeste's Switching the Supply quest, which sends you to find and turn the valve in the tunnels under the Spaceport, rewards a Spaceport Trench Tower Key. Her Turnabout quest sends you to the North Trench Tower with the note "Key is Required", to locate and upload blackmail files. Turnabout rewards Heavy Gun Parts and Medium Gun Parts.

Tian Wen's Back on Top quest also asks you to mark the South Trench Tower on Spaceport. That objective does not mention a key.

Around the towers

On our map, North Trench Tower lies north east of South Trench Tower. West Hangar sits north of North Trench Tower and East Hangar east of North Trench Tower. Trench Hatch West, an extraction, lies north west of North Trench Tower, and Hatch markers need a Raider Hatch Key.
