The Coin Mining Den Key is one of the more common keys floating around Call of Duty: Modern Warfare 4 DMZ matches, which means plenty of players are carrying one without knowing exactly where it goes. The answer is a locked third-floor room in the western section of NuriGO Mall, and while the loot won't make you rich overnight, the detour is short enough to be worth it whenever you're passing through.

Where is the Coin Mining Den in MW4 DMZ?
The Coin Mining Den sits inside a small, compact building in NuriGO West, the western district of NuriGO Mall, positioned close to the area called the Grid. The building isn't large, so it's easy to move through quickly once you know the layout.
Here's the step-by-step route:
- Travel to the NuriGO West district of NuriGO Mall.
- Locate the small building near the Grid.
- Enter through the ground-floor entrance.
- Find the staircase and climb to the third floor.
- Use the Coin Mining Den Key on the locked door at the top.
- Search the room for electronics and valuables.
What loot does the Coin Mining Den contain?
The room's contents are randomized between raids, so no two visits will be identical. That said, the Coin Mining Den consistently yields electronics-focused loot rather than weapons or tactical gear.
Expect to find a mix of the following:
- Printer Parts
- CPUs
- Printed Circuit Boards
- Other miscellaneous valuables that convert into DMZ Cash when sold
Server racks line the interior, which fits the theme and makes this stop genuinely useful when you're short on CPUs or Printed Circuit Boards for crafting. There are no Weapon Caches and no lockers in the room, so don't plan this detour around finding high-rarity weapons.

Is the Coin Mining Den worth visiting?
The honest answer depends on what you need. If you're hunting top-tier weapons or dedicated weapon caches, this room won't deliver. But if you need crafting components or a quick cash injection from selling electronics, it earns its place on your route, especially since the key is common and the building is fast to clear.

How to protect your Coin Mining Den Key before the raid
Carrying any key into a DMZ match puts it at risk. If another player eliminates you before you reach the building, they can loot the key straight off your body.
The simplest protection is a Rare Backpack, which comes with a Secure Slot. Items placed in that slot stay on your person even if you're taken down, meaning the key survives the encounter regardless of the outcome.
The Coin Mining Den is one of dozens of locked rooms scattered across the map. For players looking to push further into high-value objectives, knowing every Commander and Lieutenant spawn in DMZ can help you plan a more efficient run around the same area.
What else should you know about DMZ keys?
Keys in MW4 DMZ are plentiful, and the Coin Mining Den Key is among the most frequently found. Because it's common, there's a reasonable chance you'll pick one up organically through normal looting rather than needing to target it specifically.
