Stella montis archives key is a map-specific access key in ARC Raiders. It unlocks a secured room within the Archives area of Stella Montis and is classified as an Epic key. Current item databases list it at 0.25 kg, with a value of 100 coins and a stack size of one.
The key matters because its selling price does not reflect the potential value of the room it opens. Instead of treating it as a simple 100-coin item, experienced Raiders can carry it into Stella Montis and use it to access another concentrated loot opportunity.
Quick Answer
Where do you use the Stella Montis Archives Key?
You use it on the locked Storage Room door in the Archives area of Stella Montis. The door is located in the upper section of the Archives complex, around the tunnel/Seed Vault route. Current guides identify the locked entrance as a large door that requires the Archives Key.

The low weight makes the key relatively easy to carry. However, it occupies an inventory slot because its stack size is one, so you still need to decide whether carrying it fits your current raid plan.
Where to Find the Stella Montis Archives Key
The Stella Montis Archives Key does not have a guaranteed fixed spawn that you can simply visit every raid. It can appear through normal scavenging, which means you should search containers and loot locations during your regular runs.
This makes the key different from an item placed permanently at one obvious location. Your best approach is to loot naturally rather than spending an entire raid chasing a single container.
Places Worth Searching
When looking for map-specific keys, check searchable areas such as:
- Desks and drawers
- Lockers
- Storage containers
- Bags and backpacks
- Residential interiors
- Commercial areas
- Other searchable furniture
- Loot left by eliminated players
Because the drop is random, there is no reliable route that guarantees the Archives Key every time.
Where to Use the Stella Montis Archives Key
The Stella Montis Archives Key is used inside the Archives section of Stella Montis. The exact approach can feel confusing because the area contains multiple levels, corridors, pipes, and interconnected sections.
Current guides place the locked door around the Seed Vault/Eastern Tunnel route, while other location references describe the destination as the upper or northeastern portion of the Cultural Archives. These descriptions point toward the same Archives locked-room destination but use different landmarks based on map navigation.
The important detail is this:
Look for the large locked Storage Room-style door in the Archives route rather than searching the entire Stella Montis map.
Once you recognize the correct entrance, the key interaction becomes straightforward.
Exact Archives Door Location
Finding the correct door is the hardest part for many players.
A useful route begins around the Seed Vault section. From there, move toward the tunnel area and look for the route containing pipes and elevated sections. You need to climb through the passage before continuing toward the Archives room.
The destination is not simply a door sitting in an open courtyard. It is integrated into the interior route, which is why players can walk past the area without immediately realizing they have reached the correct location.
What the Door Looks Like
The Archives entrance is a large industrial-style door. Once you reach it, the interaction prompt will indicate that the Stella Montis Archives Key is required.
If you see the correct locked Storage Room entrance, you do not need to search for a separate hidden switch or puzzle.
How to Reach the Archives Door
Follow this practical route:
- Enter Stella Montis with the Archives Key in your inventory.
- Navigate toward the Seed Vault area.
- Move into the eastern tunnel section.
- Look for the pipe-filled route.
- Climb over the pipes to reach the next section.
- Continue through the corridor.
- Watch the sides of the corridor for the Storage Room entrance.
- Approach the locked door.
- Interact with the access point.
- Use the Archives Key to enter.
The route contains potential ARC threats, so reaching the door is not simply a navigation exercise. Destructoid also warns that ARC enemies can appear along the corridor leading to the Archives room.
How to Open the Archives Room
Opening the room is simple once you reach the correct door.
Approach the locked entrance and interact with the access point. The game will recognize the Stella Montis Archives Key, consume it, and unlock the room.
Remember that keys are consumable access items. Once you use the key, you should not expect it to remain available for another visit. If you want to open the same room again during a future raid, you need another copy.
Important Before You Unlock It
Before opening the door, take a few seconds to check your surroundings.
- Listen for nearby ARC activity.
- Watch for hostile Raiders.
- Make sure you have enough inventory space.
- Avoid opening the door while being chased.
- Have an extraction plan before collecting valuable loot.
- If playing with a squad, let teammates prepare before opening.
A valuable room is only useful if you can safely leave with what you found.
What Loot Can You Find Inside?
The Archives room is attractive because it concentrates several loot opportunities into one secured location. Reported loot includes drawers, containers, computers, valuable items, and other searchable objects.
The exact contents can vary from raid to raid. You should therefore avoid treating any single loot list as guaranteed.
Potential categories include:
- High-value containers
- Drawers
- Computers
- Valuable items
- Medical-related materials
- Mechanical materials
- Other random loot
- Potential blueprint opportunities
The room’s real strength comes from loot density. Instead of opening one container and leaving, you can search multiple objects within a relatively concentrated area.
Is the Stella Montis Archives Key Worth Using?
Yes, in most situations.
The key has a listed value of only 100 coins, while the room can provide considerably more potential value than simply selling the key. The key’s low weight also makes it practical to carry until you can reach Stella Montis.
However, value depends on survival.
If your backpack is already full of excellent loot, entering a dangerous interior simply because you have the key may not be the best decision. The ideal time to use it is when your raid plan already takes you near the Archives.
Best Value Strategy
A strong approach is:
Find key → store safely → enter Stella Montis → reach Archives → unlock room → loot quickly → extract safely.
This minimizes unnecessary detours and gives you a clear objective for the raid.
Best Tips for a Safe Archives Run
The Stella Montis Archives Key can turn an ordinary raid into a high-value run, but the room should not be treated as a risk-free reward.
1. Keep the Key Safe
If possible, protect the key from unnecessary loss until you are ready to use it. Losing the key before reaching Stella Montis can turn a successful scavenging run into a wasted opportunity.
2. Leave Inventory Space
Do not enter the Archives with a completely full backpack.
A locked loot room is much less useful when you cannot pick up anything inside.
3. Watch for ARC Enemies
The approach can contain ARC enemies. Stay alert as you move through the tunnels, especially around narrow corridors where avoiding combat becomes harder.
4. Be Careful Around Shredders
A Shredder can make an otherwise simple loot run dangerous. If one patrols the route, consider waiting for an opening instead of forcing a fight.
5. Close the Door When Appropriate
Once you enter, closing the door can help create separation between you and threats outside. This is particularly useful if an enemy follows you toward the room.
6. Plan Your Extraction
Do not wait until your backpack is full to start thinking about extraction.
Know which exit you want to use before entering the Archives so you can move quickly after looting.
Common Mistakes to Avoid
Players often lose time or valuable loot because they approach the Archives Key without a clear plan.
Mistake 1: Searching the Wrong Map
The key belongs to Stella Montis. It does not unlock random doors on older maps.
Mistake 2: Selling It Immediately
A 100-coin selling value may look tempting, but the room can offer a much stronger loot opportunity.
Mistake 3: Carrying It Without a Plan
If you find the key but never intend to run Stella Montis, it may occupy an inventory slot longer than necessary.
Mistake 4: Entering With a Full Backpack
Make space before unlocking the room. You want enough capacity for the loot you discover.
Mistake 5: Fighting Everything
The Archives route is not necessarily a place where you should eliminate every ARC unit. Sometimes avoiding combat is the smarter way to preserve ammunition, armor durability, health, and time.
Archives Key vs. Other Stella Montis Keys
Stella Montis contains several location-specific keys, including the Archives Key, Assembly Admin Key, Medical Storage Key, and Security Checkpoint Key.
| Key | General Destination | Main Purpose |
| Archives Key | Archives / Storage Room | Access concentrated loot |
| Assembly Admin Key | Assembly area | Unlocks an admin room |
| Medical Storage Key | Medical Research | Access medical storage |
| Security Checkpoint Key | Security Checkpoint | Unlocks checkpoint room |
Each key supports a different route. If you collect several of them, consider planning a single Stella Montis raid around multiple locked-room objectives.
Should You Keep or Sell the Key?
For most players, keep the Stella Montis Archives Key.
The 100-coin sale value is modest compared with the potential loot opportunity behind the locked door. The key also weighs only 0.25 kg, making it relatively inexpensive to carry.
Sell it only when you have a specific reason, such as:
- You desperately need inventory space.
- You do not plan to run Stella Montis.
- You already have more keys than you can reasonably use.
- You need immediate currency for another priority.
Otherwise, saving it for a planned raid makes more sense.
How to Get the Most Value From the Archives Room
The best way to maximize the room is to combine preparation with efficient looting.
Before entering Stella Montis, make sure you have:
- Enough backpack space
- Suitable healing supplies
- Enough ammunition
- A clear extraction route
- The Archives Key
- A plan for avoiding unnecessary fights
Once inside, search systematically rather than randomly. Start with the most valuable-looking containers and move through the room without wasting time on unnecessary inventory management.
If you are playing with teammates, coordinate who carries which items. A squad can extract more total value when everyone manages backpack space efficiently.
Why the Archives Key Matters in ARC Raiders
The Stella Montis Archives Key represents an important part of the extraction-shooter gameplay loop.
You find an item during one raid, decide whether to protect it, create a future objective around it, enter a dangerous area, and then attempt to extract with an even more valuable haul.
That creates a meaningful risk-versus-reward decision.
The key itself is not the final reward. It is the tool that gives you access to another opportunity.

Final Verdict
The Stella Montis Archives Key is more valuable as an access tool than as a 100-coin sale item. Its low weight makes it easy to preserve, while the locked Archives room offers several opportunities to increase your haul.
The most important part is knowing the route: head toward the Seed Vault and tunnel section, navigate through the pipe-filled route, find the Storage Room entrance, and use the key when the area is safe.
