## Arc Raiders: Where to Find the Residential Master Key
The Residential Master Key can be found inside the **Ruby Residence** building on the Dam Battleground map. Here’s how to locate it:
– The Ruby Residence building is on the north-eastern side of the map.
– It is positioned just east of the **Hydroponic Dome Complex** and in front of the **Pale Apartments**.
– The Residential Master Key is a **random drop** inside the building.
– To find it, go to the second floor and search near the computer desk.
Since it is a random drop, it’s recommended to also check other apartments like the **Research and Administration building** to increase your chances of finding it.
Once you acquire the key, return to **Speranza** to add it to your inventory.
