Stella Montis is ARC Raiders' first all-indoors map with tons of areas to explore and loot rooms to open. The Assembly Admin room is one of those loot rooms that are locked, and players will need a key to unlock it. Bringing a key to open up the door is definitely worth it, as there are enough loot areas inside to get your character's inventory filled to the brim.

Where to Use Stella Montis Assembly Admin Key in ARC Raiders (Door Location)
To use the Stella Montis Assembly Admin key in ARC Raiders, players will need to head to the Central Corridor in the Assembly area. The area can be found in the upper section of Stella Montis, in the western section of the map. It's an area that's notorious for PvP encounters, so you should go in solo and ready for a fight.
Before starting the raid, it's recommended to keep at least one Jolt Mine in your inventory to cover the entry. Also, keep the key in your safe pocket.
After heading east from the Lobby, you'll pass through an open area with machinery and bridges. It's best that you avoid adjusting the bridges and instead drop down to quietly move to the locked door.
Make your way into the Assembly Area's Central Corridor, and you'll come across the door just to your right. Use the Stella Montis Assembly Admin key to unlock it.
Once you're inside, make sure to close the door behind you and put a Jolt Mine next to the door to shock any trespassers that try to enter. Now that you have the room all to yourself, start searching the loot areas on the first floor.
There are a couple of drawers, cabinets, and monitors you can search inside to get valuable resources, and even epic-rarity items. The second floor has a similar layout, so you should be able to loot the whole room within minutes. Before you exit the room, make sure to put anything important in your safe pocket and head for a nearby extraction to bring all your loot back to Speranza.
You can get the Stella Montis Assembly Admin key as a random loot drop from residential areas and high-value loot areas like facilities.
