Spaceport trench tower key is an Uncommon key in ARC Raiders that provides access to locked rooms inside the Trench Towers on the Spaceport map. The towers sit in the northern section of the map, and the key can be used at either the North or South Trench Tower.
The key is especially useful because the locked rooms contain valuable loot and can also matter for quest progression. If you already have one, protect it before entering a dangerous raid and plan your route around the tower instead of treating the key as an afterthought.
What Is the Spaceport Trench Tower Key?
The Spaceport Trench Tower Key is a dedicated access item for the Trench Towers. It is classified as an Uncommon key, has a stack size of one, and has a listed value of 100 Coins.
The important detail is its flexibility. You are not restricted to only one tower. The same key type can work at the North or South Trench Tower, giving you an opportunity to choose the safer approach during your raid.
The key also has a quest connection. Celeste provides one during the Turnabout quest, where the player must reach the North Trench Tower and upload blackmail files.

Where to Find the Spaceport Trench Tower Key
The key is obtained through scavenging and random loot opportunities. Its appearance is not guaranteed, so you should search containers carefully instead of expecting it to appear in one fixed location every time.
A useful farming approach is to search residential and administrative interiors on Dam Battlegrounds. Locations such as Ruby Residence and the Research and Administration building have been reported as productive places to check.
Because loot is randomized, finding the key can take multiple raids. The smart approach is to search several relevant containers during the same run rather than repeatedly checking one exact spot.
What to Search
Prioritize containers and locations such as:
- Residential storage
- Drawers and cabinets
- Suitcases
- Backpacks
- Desks
- General loot containers
- Administrative interiors
- Other high-density scavenging areas
Do not assume that an unsuccessful search means the location is useless. Randomized loot means another raid can produce a completely different result.
Best Places to Search for the Key
One of the most practical farming routes starts around Ruby Residence on Dam Battlegrounds. Players have reported finding the key there, making residential interiors worth checking when you are specifically hunting for it.
The Research and Administration building is another location worth searching. Rather than rushing through, check containers systematically and prioritize areas with multiple searchable objects.
A good farming route should also consider extraction. If your backpack is already full, continuing to search for a key can expose you to unnecessary danger. Take the key when you find it, secure it, and decide whether the remaining raid is still worth the risk.
How to Reach the Trench Towers
Once you have the key, your objective changes from searching to positioning.
Travel to Spaceport and move toward the northern section of the map where the Trench Towers are located. The North and South towers are close enough that you can choose between them depending on your approach, enemy activity, and squad position.
Before climbing toward a locked door, listen for nearby movement. Other Raiders may have the same idea, especially when the area offers valuable loot or a quest objective.
The safest approach is rarely a straight sprint. Use cover, observe the surrounding area, and avoid making unnecessary noise before reaching the tower.
North vs. South Trench Tower
The biggest advantage of the key is that it can be used at either Trench Tower.
| Tower | Location | Key Compatible | Best Use |
| North Trench Tower | Northern Spaceport | Yes | Quest progression and loot |
| South Trench Tower | Northern Spaceport | Yes | Alternative loot route |
| Both towers | Trench Tower area | One key per locked use | Flexible raid planning |
If you are completing Turnabout, the North Trench Tower is the important destination because the quest specifically sends you there.
For a normal loot run, however, your choice can depend on your current position. If the South Tower is safer and closer, there is little reason to force a dangerous route to the North Tower.
How Many Doors Can the Key Open?
This is one of the most important details to understand before using the key.
The Trench Tower complex contains multiple locked doors across the towers. Current community references describe eight locked doors across the Trench Towers, with each tower containing locked rooms on the first and second floors.
However, do not assume that one key lets you repeatedly open every door. Keys are consumable access items, so you should treat each use as a meaningful decision.
The best strategy is to decide which locked room offers the greatest value for your current objective before interacting with the lock.
What Loot Can You Find Inside?
The main reason to carry the key is access.
Locked rooms in ARC Raiders can concentrate useful resources, making them attractive targets for Raiders who want to improve their extraction haul. The exact contents can vary because loot availability and room rewards can change through game updates.
You may encounter useful electronic, mechanical, weapon-related, or crafting resources depending on the room and current game balance.
Instead of entering with an empty inventory expectation, bring enough space to actually carry what you find. A successful key run becomes much less valuable if you have to leave useful items behind.
Loot Preparation Checklist
Before opening the room:
- Free several inventory slots.
- Carry healing supplies.
- Check your ammunition.
- Watch for nearby enemies.
- Decide your extraction route.
- Avoid unnecessary fights.
- Keep the key secure before reaching the tower.
The goal is not simply to open a door. The goal is to open it, collect useful resources, and successfully return to safety.
How the Key Helps With the Turnabout Quest
The key has a direct connection to Celeste’s Turnabout quest.
During the quest, Celeste provides the required key, and the objective directs you to the North Trench Tower. Once there, you must access the relevant area and upload the blackmail files.
This makes the key particularly important for quest-focused players. If you receive the key for Turnabout, do not treat it like ordinary loot that you can casually sell or risk during an unrelated raid.
Turnabout Objective Flow
- Accept the Turnabout quest from Celeste.
- Receive the Spaceport Trench Tower Key.
- Keep the key secure.
- Enter a Spaceport expedition.
- Travel toward the North Trench Tower.
- Unlock the required area.
- Upload the blackmail files.
- Complete the objective.
- Extract safely.
The quest creates an excellent reason to combine progression with a carefully planned Spaceport run.
Best Way to Protect the Key
Losing a key before using it can waste an entire preparation cycle.
If you already own the Spaceport Trench Tower Key, protect it as carefully as possible. The safest approach is to keep it in a protected inventory location when the game mechanics allow it.
Avoid carrying the key casually while fighting unnecessary enemies. A short detour for low-value loot is not worth risking an important access item.
Key Protection Rules
- Secure the key before entering a dangerous area.
- Avoid unnecessary PvP encounters.
- Do not overstay after completing your objective.
- Plan extraction before opening the room.
- Leave when your backpack contains valuable loot.
- Do not confuse the North and South towers with unrelated Spaceport towers.
That final point matters because Spaceport contains several tower-like structures and locked areas. Always confirm that you are approaching the correct Trench Tower.
Extraction Strategy After Opening the Tower
Opening the room is only half the job.
The Spaceport can become dangerous when multiple Raiders converge on a valuable location. A loud interaction, firefight, or prolonged looting session can reveal your position.
After collecting your loot, check your surroundings before leaving. If you hear another player approaching, do not automatically rush into the open. Wait for a safe opportunity or choose an alternate route.
A successful extraction is more valuable than one additional container. Once you have completed your quest objective or collected the resources you wanted, prioritize survival.
Common Mistakes to Avoid
1. Using the Key at the Wrong Tower
The Spaceport contains multiple locked locations. Verify the tower before using your key.
2. Ignoring Inventory Space
A locked room can provide more value than you expect. Empty several slots before entering.
3. Fighting Every Enemy
You do not need to eliminate everything around the tower. Avoid fights that do not improve your position.
4. Staying Too Long
After completing the objective, leave. Greed creates unnecessary extraction risk.
5. Forgetting the Quest Requirement
If you are running Turnabout, make sure you follow the North Trench Tower objective rather than choosing a different tower simply because it looks closer.
6. Treating the Key as Ordinary Loot
A useful key can save time and open access to valuable resources. Protect it until you have a clear reason to use it.
Best Loadout for a Trench Tower Run
A strong Trench Tower run does not require an expensive setup. You need a practical combination of combat ability, mobility, healing, and inventory capacity.
Consider bringing:
- A reliable primary weapon
- Enough ammunition for defensive fights
- Healing items
- Mobility equipment
- A manageable amount of spare gear
- Free backpack space
- The required key
- A clear extraction plan
Your loadout should match the goal of the raid. A quest run should favor survival and objective completion, while a dedicated loot run can focus more heavily on carrying capacity.
Is the Key Worth Using?
Yes, when you have a clear objective for the run.t
The Spaceport Trench Tower Key becomes especially valuable when you combine locked-room access with a quest, a planned loot route, or a high-value extraction. The key itself has a modest listed value, but its real value comes from what it allows you to access.
You should not judge the item only by its sell price. A key that opens valuable rooms can provide considerably more practical value than simply converting it into Coins.
The best time to use it is when you are prepared to extract the rewards. Entering with a nearly full backpack, weak combat supplies, or no escape plan reduces the value of the entire run.
