Where to use the coin mining den key in DMZ in Modern Warfare 4

In Call of Duty: Modern Warfare 4, the coin mining den key can be found during the Operation Shopping Hacks mission. This key unlocks a locked door in the e-coin mining lab, located in NuriGO West, which is east of the westernmost gas station inside NuriGO Mall. The lab is situated in a small apartment block north of The Grid, on the road north of the Netshin Tech Complex, east of a gas station, and west of the NuriGO Mall stronghold on the map.

Inside the building, adorned with a sunglasses advert, you'll find a locked door at the top of the staircase. Using the coin mining den key on this door reveals a room filled with valuable loot, such as eight electronic servers. If you're seeking electronic sensors or comms modules, this area is the ideal place to explore. For those needing high-tenacity fibers, the coin mining den key location is also a prime spot.

Additionally, guides on using the counting room vault key and gun store weapons locker key are available.
