The Spaceport Warehouse key in ARC Raiders is one of the more elusive and valuable items you can find during your scavenging runs. It grants access to a locked section of the Shipping Warehouse in the Acerra Spaceport, where hidden loot often waits behind a secured door. If you’ve been hunting for this key but can’t seem to locate it, this guide explains exactly where to find it, what to expect once you have it, and how to use it effectively without losing progress.
What the Spaceport Warehouse Key Does
The Spaceport Warehouse Key is an Uncommon item that weighs 0.25 units and can be stacked only once. It’s primarily used to unlock the northern set of doors on the second floor of the Shipping Warehouse inside the Spaceport map. Behind these doors, you’ll often find higher-tier loot than what’s available in the open areas — from crafting materials to weapon blueprints.
While it’s not part of any questline, unlocking the Warehouse can make a noticeable difference to your raid earnings.
Where to Find the Spaceport Warehouse Key
Like most keys in ARC Raiders, the Spaceport Warehouse Key is a random spawn item — meaning there’s no guaranteed drop point. However, several zones consistently yield better results when searching for keys.
1. Ruby Residence (Dam Battlegrounds Map)
This is by far the most reliable location for key farming. Ruby Residence is filled with containers, drawers, and lockers, all of which can contain various Spaceport-related keys. You can find the Spaceport Warehouse Key here if luck is on your side.
- Focus on checking every container and desk drawer inside the residential buildings.
- The spawn rate for keys seems higher in these residential interiors than in open-world crates.
- Keys found here may not be limited to this map — you can use them later in Spaceport.
2. Research & Administration Building (Dam Battlegrounds)
Another excellent hotspot for key hunting. This area often has multiple key spawn containers, especially inside offices and supply rooms. It’s also less contested than Ruby Residence, giving you time to loot safely.
3. Other Residential Areas
While Ruby Residence and the R&A Building are the best-known spawn sites, don’t ignore other residential zones across maps. Each building or apartment block has a small chance of spawning rare or uncommon keys in drawers or lockers.
Pro Tip: Once you find the key, immediately place it in your Safe Pocket to prevent losing it if you fail to extract.
How to Use the Key in the Spaceport Area
After obtaining the key, your next destination is the Shipping Warehouse in the Spaceport area. This massive structure can be a bit confusing to navigate at first, but here’s how to reach the locked door:
- Travel to the Spaceport Map and locate the Shipping Warehouse area — it’s positioned toward the northern section of the map.
- Enter through the main entrance and take the staircase leading to the second floor.
- Follow the corridor along the north side of the building until you see a locked metal door.
- Use your Spaceport Warehouse Key to open it directly from your inventory or Safe Pocket.
Once inside, take time to explore — you’ll find containers, metal shelves, and loot crates with valuable materials. It’s best to close the door behind you while looting to avoid being ambushed by other Raiders.
