All keys and doors from the spaceport
Container Storage Key (Spaceport)
Visit the container storage and look for an entrance on the eastern side of the building with a rope. Climb up there and jump only from the second floor. The locked door is on the left side.
Warehouse Key (Spaceport)
Enter the shipping warehouse and look for a staircase leading you to the first floor of the warehouse. Continue along the path until you reach a locked door.
Key to the Spaceport Control Tower
Visit the building “Control Tower A6” and set your eyes on the tower. The building has several entrances, but you only want to use the one under the tower because it leads you directly to the locked door and contains no ARCs.
Trench Tower Key (Spaceport)
Behind the starting towers are the trench towers. Both buildings each have 2 entrances on each side. Your key fits both buildings; you just need to decide which one is your favorite. Note that you lose your key when you unlock a door. So you can only open one building with one key.
