The Buried City Residential Master Key is a random drop item that can be found in various residential areas across ARC Raiders maps. Players will need to explore these areas on different runs, in the hope of finding it in a drawer, cabinet, suitcase, or simply sitting on a shelf. Here are some of the best locations where you can find the Buried City Residential Master Key in the game.

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 (same location mentioned in GameRant’s trinkets guide). Compared to locations in Dam Battlegrounds, these areas will have high raider activity, so be careful.
