Arc Raiders Spaceport Trench Tower Key: Where to Find and Use

The Spaceport Trench Tower Key in Arc Raiders unlocks a specific loot room inside the Spaceport map’s trench area, and you can find it by defeating the key holder or searching high-value loot spots within that same zone. This guide explains exactly where the key spawns, which door it opens, and what you can expect inside.

Background: What Is the Spaceport Trench Tower Key?

Arc Raiders is a cooperative extraction shooter where players drop into maps to complete objectives, fight AI enemies, and extract with valuable loot. The Spaceport map is one of the larger, more complex zones, featuring a central trench system that runs along the eastern side. The Trench Tower is a tall structure overlooking that trench, and its key is a special item that grants access to a locked room on one of the tower’s upper floors.

Keys in Arc Raiders are single-use items that take up inventory space. Once used, they disappear, so you want to be sure you’re at the right door before using it. The Trench Tower Key is specific to the Spaceport map; it won’t work on any other map’s locked rooms.

How the Key Works

The key functions like other door keys in the game: you must have it in your inventory (not in your stash) to open the matching door. When you approach the locked door, a prompt appears to use the key. After unlocking, the door opens permanently for that raid, and the key is consumed.

The locked room itself is a small loot room with a few containers, a weapon rack, and sometimes a medical crate. It’s not a high-tier loot room like those found in the Spaceport’s main terminal, but it’s a reliable source of mid-tier gear and crafting materials. The room is particularly useful early in a raid because it’s relatively safe—the trench area has fewer AI patrols than the central buildings.

Where to Find the Spaceport Trench Tower Key

The key can spawn in several locations within the Spaceport map. Based on community mapping and in-game observations, the most common spawn points are:

• On the body of a key holder: A specific AI enemy, often a higher-tier raider, may carry the key. You’ll need to defeat them and loot their body. The exact spawn location of this enemy varies, but it’s typically near the trench or on the tower itself.
• Inside the trench’s underground tunnels: Search the small rooms and alcoves along the trench walls. Keys can appear on tables, shelves, or inside toolboxes.
• In the tower’s lower floors: Before you reach the locked door, check the rooms on the first and second floors. Keys sometimes spawn on desks or in lockers.
• On a shelf in the maintenance shed: There’s a small shed at the north end of the trench. The key can spawn on a shelf inside.

Keep in mind that key spawns are randomized each raid. You might find the key in one location in one raid and in a completely different spot in the next. There’s no guaranteed spawn point, so you’ll need to check multiple locations.

How to Use the Key: Step-by-Step

Once you have the key, follow these steps to unlock the tower room:

1. Locate the Trench Tower: It’s the tall industrial structure at the eastern edge of the trench, marked by a large antenna on top.
2. Enter the tower: The main entrance is at ground level on the west side. There are also stairs leading up from the trench floor.
3. Climb to the third floor: The locked door is on the third floor, at the end of a short hallway. It’s a metal door with a yellow hazard stripe and a keycard slot.
4. Approach the door and press the interaction key: Your character will use the key automatically if it’s in your inventory.
5. Loot the room: Inside, you’ll find a few containers. Prioritize the weapon rack and the medical crate, as they often have the best items.

Be aware that using the key makes a loud sound that can attract nearby AI. Clear the area before unlocking, and consider closing the door behind you to buy time if enemies come.

Common Mistakes and Misconceptions

One common mistake is confusing the Trench Tower Key with the Spaceport Terminal Key. They are different keys that open different doors. The Terminal Key opens a room in the main terminal building, not the tower. Always check the key’s name and description before heading to a door.

Another misconception is that the key is a guaranteed extract item. It’s not. It’s just a key to a loot room. The room’s contents are randomized, and you might get low-tier items. Don’t risk your life just for this room if you’re already carrying high-value loot.

Players also sometimes forget that the key takes up inventory space. If you’re full, you might have to drop something else to pick it up. Plan your inventory accordingly.

Tips for Farming the Key

If you’re specifically hunting for the Trench Tower Key, here are some strategies:

• Rush the trench at the start of a raid: The key spawns are most likely to be uncontested early on. Head straight to the trench and check the known spawn points quickly.
• Listen for the key holder: The AI enemy that carries the key often has a distinct voice line or patrol pattern. If you hear a raider shouting orders near the trench, it might be the key holder.
• Check the same spots every raid: While spawns are random, certain spots seem to have a higher chance. The maintenance shed and the underground tunnels are worth checking every time.
• Use a high-perception character: If your character has a high Perception stat, you’ll see loot highlights from farther away, making it easier to spot the key on shelves or in corners.

Remember that the key is not the only valuable thing in the trench. Even if you don’t find it, you can still loot other containers and extract with decent gear.

Frequently Asked Questions

Can the Spaceport Trench Tower Key be used on other maps?

No, the key is map-specific. It only works on the Spaceport map’s Trench Tower door. Keys for other maps, like the Terminal Key, are separate items.

What’s inside the Trench Tower locked room?

The room contains a few containers with mid-tier loot: a weapon rack that can hold common or uncommon weapons, a medical crate with bandages and medkits, and a tool chest with crafting materials. It’s not a high-tier room, but it’s a decent source of supplies.

Is the key a guaranteed drop from a specific enemy?

No, the key is not a guaranteed drop from any single enemy. It spawns randomly in the map, sometimes on an enemy, sometimes in the environment. There’s no fixed boss that always drops it.

How many times can I use the key?

Once. Keys in Arc Raiders are single-use. After you unlock the door, the key disappears from your inventory.

Does the key take up inventory space?

Yes, the key occupies one inventory slot. If your pack is full, you’ll need to drop something to carry it.

Can I sell the key to a vendor?

Yes, you can sell the key to a vendor for in-game currency. The price is modest, so it’s usually better to use it for the loot room, unless you already have several keys.
