U4GM How to Find the Buried City Residential Master Key Door ARC Raiders

Most green keys in ARC Raiders end up being dead weight, but the Buried City Residential Master Key actually earns its slot. If you're chasing blueprints and don't fancy getting third-partied every time you open a drawer, this route helps a lot. I started treating it like a "reset button" run: quick in, quick out, low drama, and the kind of loot tables that make you check your bag twice. Before you head out, it's worth knowing what you're hunting and why, and that's where ARC Raiders Items can be handy for getting your bearings on what's worth the space.



Getting to the Door
You're looking for the Grandioso Apartments, and the northern building is the one that matters. Don't overthink it. Get to the first floor, then drift to the eastern side of that building and you'll spot the locked room tucked out of the main sprint line. A lot of players blow past it because they're focused on the obvious angles and stairwells. That's kind of the point. If you come in calm, listen for footsteps, and don't slam every door on the way, you can usually get in without broadcasting your plan to the whole block.



What You Can Pull Inside
Once it's open, the room feels like someone built it for blueprint hunters. You've got a bunch of filing cabinets and drawers that you can work through fast, plus an ammo crate and a med bag that's saved me more than once when a run went sideways. The Security Breach locker is the little "bonus roll" that keeps it exciting. I've pulled blueprint-grade items out of blue suitcases, and I've also found legit weapons sitting in places you'd normally ignore, like a kitchen cupboard or a wardrobe. It's not guaranteed, but it's consistent enough that you don't feel like you're wasting a raid.



Profit, Timing, and Staying Alive
On a clean run with an empty pack, 40,000 Coin profit is very real, and if the RNG leans your way you can push closer to 50,000 without doing anything heroic. The Grandioso area usually plays calmer than the true meat-grinders, but don't start daydreaming while you're looting a desk. Night Raids can bump the quality up, yet they also pull in the people who know exactly what this key is for. If you show up late, you'll notice the place is often picked clean, so it pays to rotate in early, loot with purpose, and leave before you get stubborn about "one more cabinet."



Making the Run Repeatable
The trick is treating the Master Key room as your anchor point, not your whole raid. Hit it, sort your bag fast, then plan a simple exit line that avoids the loudest crossings. If you're building up bankroll or trying to replace gear after a bad streak, it's the kind of route you can run back-to-back without burning out. And if you ever want to top up Coin or grab specific gear without waiting on luck, plenty of players also use services like U4GM to keep their loadouts moving while they focus on learning safer routes and better fights.Welcome to U4GM—no fluff, just solid ARC Raiders help.
