Arc Raiders: Spaceport Keys Guide

In ARC Raiders, the Spaceport map is one of the most rewarding yet challenging areas to explore. It’s packed with locked rooms, secret passages, and valuable loot hidden behind secured doors — all of which require specific keys to access. Knowing where to find these keys and how to use them properly can greatly improve your chances of success during raids.

This guide covers everything you need to know about Spaceport keys — where to locate them, what each one unlocks, and how to use them efficiently without losing progress. Whether you’re looking for faster extraction routes or hidden loot rooms, this overview will help you navigate the Spaceport more effectively and make the most out of every run.

Where to look for keys and how to obtain them

Most of the keys are located on the Dam Battlegrounds map, primarily around Ruby Residence and the Research & Administration Building. These areas serve as the main spawn points, so it’s worth checking every room, crate, table, and locker carefully. The best strategy is to focus on residential and administrative buildings, as the drop rate for keys tends to be higher there. Since loot respawns after completing missions, make a habit of revisiting Ruby Residence from time to time. Additionally, some keys can occasionally drop from Arc enemies, especially those guarding restricted zones.

Types of Keys in The Spaceport

On the Spaceport map, several keys can be found that unlock doors or special passages. The main ones include:

These keys allow players to access locked areas with higher-tier loot compared to standard locations.

Spaceport Trench Tower Key

The Spaceport Trench Tower Key unlocks a door inside the Trench Tower building located in the Spaceport area. The locked door can be found within the Trench Tower — enter the “Trench Tower” zone, a distinct section of the Spaceport, and look for a tall building with stairs or ziplines leading upward. Once inside, the door is located on one of the upper levels, usually around the second or third floor, or accessible via the top platform. Climb using the stairs or a zipline, and once you reach the higher section, look for a door with a red lock or labeled “locked door/ key required.” That’s the one opened by the Trench Tower Key.

Here’s what the door itself looks like:

Spaceport Container Storage Key

The area is located in the Container Storage section within the Spaceport.To reach it, go up the stairs or climb to the top floor of the Container Storage building — the key unlocks a door located on the upper level. The door may appear red or be labeled “locked door/ key required.” Once opened, you’ll find a room inside containing rare loot.

Here’s what the door itself looks like:

Spaceport Ground Control Key

The Spaceport Ground Control Key is used to unlock a door inside the Ground Control Tower in the Spaceport area.

To find it, locate the Ground Control Tower within the Spaceport. Enter the structure and head to the upper levels — the locked door is situated inside the tower, usually at a height accessible via stairs or a zipline. Look for a door marked “locked door/ key required,” which can be opened using the Spaceport Ground Control Key.

Spaceport Outskirts Bunker Key

The Spaceport Outskirts Bunker Key is used to unlock a door inside the Outskirts Bunker located in the Spaceport area. The bunker is situated on the outer edge of the Spaceport zone — typically near the map’s boundary, where the area opens into a wide, open space. To find the entrance, look for a concrete shelter or bunker with a metal door, often hidden among containers or cover structures in the Outskirts section. Once inside, you’ll find the locked door within the bunker — use the key to open it and gain access to the loot room.

Here’s what the door itself looks like:

Spaceport Warehouse Key

On the Spaceport map, find the area called Shipping Warehouse. This is the location associated with the Spaceport Warehouse Key.Inside the warehouse building, look for a room with metal structures and containers — the locked door may appear red or be marked with “locked door/ key required.” Use the Spaceport Warehouse Key to unlock it and access the loot hidden inside.

Here’s what the door itself looks like:

How to Use Keys Effectively in ARC Raiders

Keys on the Spaceport map are used to open locked rooms that often contain better loot than regular areas. You can find most of them near buildings like the Trench Tower, Ground Control Tower, or Shipping Warehouse. Check desks, lockers, crates, and shelves inside these structures — that’s where keys usually appear. Sometimes they also drop from enemies, especially tougher ones guarding restricted zones. It’s worth visiting these spots regularly, as loot tends to respawn after missions.

Each key opens a specific door. For example, the Spaceport Trench Tower Key is used in the Trench Tower, while the Warehouse Key opens a locked room inside the Shipping Warehouse. Behind these doors, you’ll often find useful loot such as weapons, materials, ammo, and crafting items. Using keys is a good way to improve your loadout and earn extra resources for future raids.

Try to use the keys before extracting from the map — if you die, they’ll disappear from your inventory. Mark the door locations you discover so you can return to them later.
