The Buried City Residential Master Key is one of the best green rarity keys in ARC Raiders. Here’s where to use it.
The Buried City Residential Master Key is one of the best green-rarity keys I’ve opened, and it’s especially useful if you’re hunting for blueprints. The door where you use it isn’t the easiest to find, but once you know where it is, it’s a pretty safe room to loot and extract with the goods.
Where to use the Buried City Residential Master Key in ARC Raiders

You use the Buried City Residential Master Key on the first floor of Grandioso Apartments.

You’ll find the lockedroom on the eastern side of the northern building.

Inside is a veritable smorgasbord of residential loot containers, including:
At least six filing cabinets and drawers of various types
An ammo crate
At least one suitcase
A med bag
A Security Breach locker
A wardrobe with weapons and valuable spawns
A computer
All of the filing cabinets and drawers can spawn blueprints, valuables, weapons, and other goodies. I managed to pull a Wolfpack blueprint from the blue suitcase as well as an Osprey from the cupboard in the kitchen.

Adding in all the valuables, ammo, and other items I found, I made 40,000 Coin in profit, from 80,000 to over 110,000. If you go into the Buried City Residential Master Key with an empty pack and get luckier than I did, a 50,000 Coin haul is not out of the question.
The Grandioso apartments are also a relatively safe loot location, and you can increase the value of what you find there during a Night Raid or other map condition. Note that blueprint hunters will be more common at night.
I didn’t run into anyone when I used the Buried City Residential Master Key, but Grandioso was almost always looted on other Night Raids I did.
