Spaceport Trench Tower Key ARC Raiders Guide: Locations, Usage, and Turnabout Quest Tips

Unlocking hidden loot rooms in ARC Raiders often depends on rare keys — and the Spaceport Trench Tower Key is one of the most valuable among them. It’s not only tied to the Turnabout questline but also grants access to multiple locked doors inside the Acerra Spaceport’s Trench Towers, where high-tier rewards are stashed.

What Is the Spaceport Trench Tower Key?

The Spaceport Trench Tower Key is an Uncommon item weighing around 0.25 kg. Its description reads:

“Unlocks a door to the Trench Towers in Spaceport.”

It functions much like other key items in ARC Raiders, such as the Blue Gate Confiscation Key or Dam Keys — rare drops that open specific high-value locations. The Trench Tower Key can be looted, scavenged, or obtained through PvP encounters, but it’s never guaranteed.

Where to Find the Trench Tower Key

You won’t find this key lying in plain sight on the Spaceport map. Instead, it usually spawns elsewhere — primarily on the Dam Battlegrounds map — before you bring it back for use.

Reliable Spawn Locations

• Ruby Residence (Dam Map): Search the north-western building; loot containers here occasionally yield the key.
• Research & Administration (Dam Map): Located near Small Creek, next to the Primary Facility. Containers and desks here are popular spawn points.
• Pale Apartments: Another Dam location known to spawn different Spaceport keys, including the Trench Tower Key.

Tip: Since spawns are random, plan multiple Dam runs. Extract safely once you find the key — dying before extraction will cause you to lose it.

How to Use the Key at Spaceport

Once you’ve secured the key, head to Acerra Spaceport. This region contains both the North and South Trench Towers, but only one specific key type opens their locked interiors.

Step-by-Step Usage

1. Go to the Trench Towers area on the Spaceport map.
2. Enter the North or South Trench Tower. Each tower has two doors per floor, totaling eight locked doors across both.
3. Climb the blue staircase on the left side of the facility — you’ll spot a locked metal door.
4. Use the Spaceport Trench Tower Key from your inventory to unlock it.
5. Be ready for resistance. Enemy ARCs often guard the loot rooms inside. Clear them before looting.

Completing these steps will grant you access to valuable loot caches and shortcuts through the Spaceport facility.

How to Increase Your Key Drop Chances

Since key drops in ARC Raiders rely on RNG, efficiency and repetition are essential.

• Run light gear on Dam Battlegrounds for quick movement between containers.
• Target high-loot zones marked in red on the in-game map; they have a higher chance to drop uncommon items.
• Avoid peak hours if playing online — fewer players means less competition for loot.
• Check player corpses: Eliminating and looting other players often yields keys, especially near popular extraction zones.

Quest Connection: The Turnabout Mission

The Turnabout questline requires at least one Spaceport Trench Tower Key. If you plan on progressing that mission, keep one in reserve before selling or using it for random loot runs. Without it, certain Spaceport objectives cannot be completed.

Important Tips Before You Go

• Don’t confuse it with other Spaceport keys. Only keys labeled “Trench Tower” work on these doors.
• Bring spare inventory space — loot inside Trench Towers can include rare attachments or high-value materials.
• Extract immediately after looting. Spaceport is a hotspot, and staying too long increases the risk of losing your hard-earned rewards.
