Bring a second, if you have it

The Call of Duty: Modern Warfare 4 DMZ blackmarket weapons locker key is one of many keys in the extraction mode, and it's used to open, as you may have guessed from its name, a locker that can contain rare weapons and loot. Much like the gun store weapons locker key, however, the blackmarket weapons locker key can be used in two different locations.

Here's a complete guide on where you need to go to use the blackmarket weapons locker key in DMZ in Modern Warfare 4.

Blackmarket weapons locker key locations in DMZ

The left-hand side of the image shows the player looking at the blackmarket weapons building while the right-hand side shows the location of the two buildings marked on the in-game map with a star icon.

There are two locations where you can use the blackmarket weapons locker key in DMZ, and each location has two lockers. So if you have multiple keys, you can grab the goodies from up to four locked containers in one deployment. The image above shows where both blackmarket weapons lockers can be found, at both Hanrin Village and Deadtown, along with the building you're looking for.

When you've found the correct building, indicated by the wrought iron gates on the front and the red advert above it for an MP3 player, head inside and look for the stairs down to the basement. Go through another door and you'll discover the two lockers in a room with a few other lootable containers, pictured above.

Use two keys, if you have them, to open both of the lockers, along with anything else in the room you want to take, then get the heck outta there. These rooms can have some valuable stuff. In the screenshot above, you can see that I came away with two decent 3D printer recipes, a purple LMG, a purple armor vest, and a plethora of crafting materials, after looting just two of the lockers.
