Buried City Residential Master Key Location in ARC Raiders

The Buried City Residential Master Key in ARC Raiders can be used to open two separate locked doors found on the Buried City map. This key is classified as Uncommon rarity, which makes it easier to obtain than many Epic rarity keys that exist in the loot pool. In this guide, you’ll learn how to obtain the Buried City Residential Master Key and where exactly you can use it once you have it.

How to Get the Buried City Residential Master Key in ARC Raiders (Location)

The Buried City Residential Master Key is obtained as a random loot drop and can appear in several residential-type locations across ARC Raiders maps. To get it, players will need to repeatedly explore residential zones during multiple runs, as the key can spawn in a variety of containers or spots. You may find it inside drawers, cabinets, suitcases, or even placed openly on shelves.

Since the drop is not guaranteed, consistent looting of residential buildings is the best approach. Below are some of the most reliable locations where players have a higher chance of finding the Buried City Residential Master Key during their raids.

Map	Buried City Residential Master Key Location	Map Location
Dam Battlegrounds	Players can check out the Pale Apartments, Ruby Residence, and the Pattern House on each run of Dam Battlegrounds to get the Buried City Residential Master Key. These areas are on the outskirts of the map, so they're relatively safe from PvP action (unless a player spawns next to them).
Buried City	Two of the best locations to find the key in Buried City are the Grandioso Apartments and the group of houses east of the Abandoned Highway Camp. Compared to locations in Dam Battlegrounds, these areas will have high raider activity, so be careful.

Where to Use the Buried City Residential Master Key in ARC Raiders

The Buried City Residential Master Key can be used to unlock two specific doors located on the Buried City map. One of these doors is inside the Grandioso Apartments, while the other is an apartment entrance located near Main Street.

For the Main Street apartment, head toward the location marked as Door 1 on the map image shown above. The entrance is located at street level, and you can use the Buried City Residential Master Key directly on the door to gain access. Inside, there are two floors that can be explored, offering a decent amount of loot for the effort required.

The second and more rewarding location to use the Buried City Residential Master Key is inside the Grandioso Apartments. Enter the Grandioso Apartment building from the point indicated on the map image above. Once inside, locate the elevator shaft and descend one level to reach level 02.

From there, enter the only room connected to the hallway, where you’ll find the locked apartment door. Use the Buried City Residential Master Key to unlock it and begin looting the interior. Be sure to thoroughly search both rooms within the apartment, including the balcony area, which can be accessed by breaking the glass for additional loot.
