ARC Raiders‘ newest map, Stella Montis, has several areas that require a key to access, and the Archives room can help you out with some incredible rewards.
The room will be initially locked when you first come across it in Stella Montis. Once you have the key, you can unlock the door and loot as many items as you can (and want). This guide will tell you about possible locations where you can obtain the key, and where to use it if you manage to get lucky.
Where to find the Stella Montis Archives key in ARC Raiders
The Archives key, like all other non-quest keys, can spawn at random places on the map. I managed to find mine at a house on the Blue Gate map, and I have marked its location on the screenshot below for your convenience. My friend managed to find his from one of the houses in Buried City. Hence, areas tagged as Residential appear to be a good spot.
I would also advise taking a thorough look through the Ruby Residence building on Dam Battlegrounds. This apartment has plenty of containers to breach and loot. The Ruby Residence building has been my favorite spot when it comes to getting keys in the game.

Another popular spot for finding keys is the containers in the Research and Administration building, which also spawns a lot of keys. However, I haven’t found either the Archives key or any other related to Stella Montis, for that matter, at this location.
Keep in mind that there’s no guaranteed spawn point for the Archives room key.
Where to use the Stella Montis Archives key in ARC Raiders
The location of the Archives room can be quite confusing. You’ll have to start from the location marked below, which is near the Seed Vault. From there, we are going to head straight and climb a couple of pipes to the upper level.

Take the door straight, and continue moving forward until you have reached the following location. This part is easy, as you have to keep following the straight corridor, and the Archives room will fall on your right (use the corridor highlighted by my mouse to reach the marked location in the screenshot below).

Be careful, as I have come across ARC enemies on this corridor. If you find a Shredder, I will try to avoid it at all costs. Use the key to open the garage-type door of the Archives door, go inside, and close it to prevent the Shredder from getting inside.
