The Spaceport Trench Tower Key is one of the most valuable and rare keys in ARC Raiders. Unlike many other locked locations scattered across the map, the doors tied to this key guard some of the largest concentrated loot caches currently available on Spaceport.
In fact, the biggest challenge often isn’t finding loot – it’s having enough inventory space to carry it all out safely.
If you’ve managed to secure this key, here’s exactly where to use it, what kind of rewards to expect, and how to maximize your run.
Where to Use the Spaceport Trench Tower Key
You can use the Spaceport Trench Tower Key at:
·North Trench Tower
·South Trench Tower
Both towers are located in the northernmost section of the Spaceport map. The key works on either building, and if you or your squad bring two keys, you can unlock both towers in a single raid.
Door Locations
Each tower has locked doors positioned on opposite sides of the structure. Once you unlock one door, you’ll be able to access and open the remaining internal doors from the inside – making a single key sufficient for fully clearing one tower.
North Trench Tower Loot Breakdown
The North Trench Tower offers a solid variety of high-value loot containers, including:
·1 Weapon Box
·Bank of Red Valuable Lockers
·Several Drawers
·Breachable Electronics Boxes
·1 Med Case
·1 Security Breach Locker
·Loose Electronic and Mechanical loot spawns
This tower leans slightly toward electronics and medical items, making it a strong choice for players farming crafting components or mid-tier gear upgrades.
South Trench Tower Loot Breakdown
In my experience, the South Trench Tower is the more lucrative of the two. It contains:
·1 Weapon Box
·1 Grenade Case
·Bank of Computer Server Towers
·Several Red Valuable Lockers
·Breachable Computer Boxes
·Breachable Blue Mechanical Boxes
·Multiple Drawers with residential loot potential
The presence of server towers and mechanical boxes makes this tower particularly attractive for players seeking high-value crafting materials and advanced ARC Raiders Items.
How Much Is the Loot Worth?
Based on testing and full clears:
·Clearing one tower completely can yield 30,000-40,000 coins worth of loot.
·Clearing both towers with two keys can result in 100,000+ coins in extracted items.
These numbers depend on:
·RNG spawns
·Your ability to breach containers
·Inventory capacity
·Survival and successful extraction
If you’re going solo, prioritize high-value items over bulk materials. If you’re running a coordinated squad, you can split loot roles – one player focuses on electronics, another on valuables, another on weapons.
Inventory Space Is the Real Limiter
Because of the density of loot inside these towers, space management becomes critical.
Before entering:
·Upgrade your backpack whenever possible.
·Clear unnecessary gear from your inventory.
·Bring breaching tools to access additional containers.
·Plan extraction routes in advance.
Players looking to optimize their loadouts often prepare beforehand by upgrading gear or sourcing better storage options. For those trying to speed up progression, some players also look to buy ARC Raiders Blueprints to unlock stronger crafting paths earlier.
Having upgraded storage or access to improved crafting unlocks can dramatically increase the efficiency of Trench Tower runs.
Environmental Threats: Watch the Airspace
The towers are not uncontested.
Rocketeer Patrols
A Rocketeer frequently patrols the airspace near the Trench Towers. This airborne threat can:
·Interrupt looting
·Force repositioning
·Reveal your location to other Raiders
You’ll also want to watch for:
·Raider flares (indicating nearby players)
·Ambush attempts from squads camping extraction routes
·Late-arriving teams hoping to third-party your clear
Because these towers are high-value zones, they often attract PvP activity.
North vs South: Which Tower Should You Open?
If you only have one key and limited time, here’s a quick comparison:
·North: Electronics + medical, 30k-35k Coin
·South: Mechanical + server loot, 35k-40k Coin
While both are excellent, the South Trench Tower typically provides more high-value mechanical and computer components, making it the slightly better option for pure profit runs.
Pro Tips for Clearing Trench Towers
1. Bring Breach Charges – Many containers require them.
2. Clear Outside First – Secure the perimeter before unlocking doors.
3. Loot Efficiently – Don’t over-prioritize low-tier items.
4. Listen Carefully – Audio cues often signal approaching Raiders.
5. Plan Extraction Before Unlocking – Don’t get greedy without an exit strategy.
Because these locations are some of the best loot concentration points on Spaceport, they’re ideal for players farming premium ARC Raiders Items for crafting, trading, or loadout upgrades.
Is the Spaceport Trench Tower Key Worth Using?
Absolutely.
Despite its rarity, the Spaceport Trench Tower Key is one of the highest ROI keys currently available in ARC Raiders. The sheer volume of containers – especially breachable electronics and valuables – makes it a prime farming location.
However, its profitability depends on:
·Survival
·Inventory management
·PvP awareness
·Squad coordination
If you’re well-prepared, a single successful run can fund multiple future raids.
Final Thoughts
The Spaceport Trench Tower Key is more than just a rare unlock – it’s a gateway to one of the most loot-dense areas in ARC Raiders. Whether you’re farming high-value electronics, stacking Coin, or preparing for high-tier crafting, both Trench Towers offer exceptional returns.
If you’re planning to farm them consistently, make sure your loadout and crafting options are optimized beforehand. Strong gear, efficient inventory space, and access to upgraded blueprints can make the difference between barely escaping and walking out with 100,000+ Coin worth of gear.be.
