ARC Raiders Spaceport Trench Tower Key — Location and Loot Breakdown

The Spaceport Trench Tower Key is a single-use key in ARC Raiders.
It unlocks a locked interior room inside one of the Trench Towers on the Spaceport map.

Once the door is opened, the key is consumed.

Before anything else:

• Always put the key in your Safe Pocket

• The locked door has red indicator lights

• Close the door after entering if you don’t want to get pushed

This key can be used on either the North Trench Tower or the South Trench Tower. Both towers are close to each other and share a very similar layout, but one key only opens one door.

How to Get the Spaceport Trench Tower Key

This key is a random drop.

You can find it through normal gameplay by looting:

• residential interiors

• desks, drawers, and storage furniture

• backpacks and containers

• other players

Keys tend to appear more often in amber / orange zones simply because those areas have more interiors and searchable objects. Over time, that’s where most keys come from.

There is no guaranteed method or route to force this key to drop.

If you don’t want to wait on RNG, LevelUpper offers ARC Raiders key delivery and boosting services, completed fully in-raid through normal gameplay and extraction.

Night Raids

Night Raids matter when using this key.

• keys drop more often during Night Raids

• locked rooms opened at Night roll better loot

If you plan to spend a single-use key on Spaceport, Night Raids are the efficient choice. Opening a Trench Tower during a daytime raid is simply lower value.

Where the Trench Tower Key Is Used

The Spaceport Trench Tower Key is used on the Spaceport map.

There are two valid locations:

• North Trench Tower

• South Trench Tower

Both towers are accessible from different sides of the map and mirror each other in structure. You must choose one—the key is consumed after opening a single door.

Important location facts

• the locked door is inside the trench tower structure

• access requires moving up through interior corridors and stairs

• ARC units can spawn inside the tower

• player traffic is common due to the central location

What the Trench Tower Room Contains

The unlocked room is a large, U-shaped interior space with containers spread throughout multiple sections and floors.

Typical loot includes:

• searchable containers and cabinets

• bags and storage crates

• breachable containers

• crafting materials and components

• consumables and utility items

• occasional weapons and high-value items

Loot is fully RNG-based.
The value of this key comes from container density across a large interior.

Make sure to fully clear the room, including upper sections—some containers can spawn slightly off the main path.

Final Thoughts & Ranking

The Spaceport Trench Tower Key is best used when it fits your route.

It opens a large interior with many containers, but you must commit to moving through a busy part of Spaceport to reach it. Choosing between North or South usually comes down to spawn position and current map flow.

This key makes sense when:

• you spawn near one of the Trench Towers

• you’re already routing through Spaceport interiors

• you’re running a Night Raid

• you’re prepared to deal with ARC spawns and player traffic

If reaching the tower requires crossing most of the map, it’s usually better to save the key for a cleaner run.

Tier Placement

In our ARC Raiders key ranking, the Spaceport Trench Tower Key is placed in Tier A. Tier A keys provide large, enclosed interiors with strong container density and reliable value, while remaining flexible enough to fit naturally into multiple routes. The Trench Tower qualifies due to its size, layout, and the ability to choose between two locations based on spawn and map flow.
