The Residential Master Key can unlock exciting opportunities in ARC Raiders, but first, you need to track it down. Obtaining keys that aren’t part of a quest can be tricky, as luck plays a big role. In this guide, I’ll point you to the prime locations for finding the Residential Master Key in Buried City.
How to Get the Buried City Residential Master Key in ARC Raiders
You can find the Residential Master Key on the Dam Battlegrounds map. Personally, I located mine after several attempts at Ruby Residence. This building has a cabinet that spawns random keys, so if you’re fortunate, you might uncover the key you need.

Another excellent location to check is the Research and Administration building. If you start here, look on the second floor where you’ll find a container that may hold random keys. Here, you could also find keys for high-tier loot areas like the Confiscation Room and the Village areas in Blue Gate.

Once you’ve secured the key, make your way to Buried City. The Residential Master Key can be used at the Grandiose Apartment situated in the southern part of the map. I’ve marked this location for easy navigation.

To enter the building, look for a broken window on the ground floor, then check the room to your left. Use your key to access all the loot available inside. Be cautious, though! There are numerous ARC enemies in this area, and it’s wise to keep a low profile to avoid confrontation. In my experience, I’ve encountered a few Raiders here as well, so stay alert!
