The description of the key states that it "unlocks the weapons lockers in gun stores, found in Western Cheongun Village and Northern Songdo Wharf," but those are still fairly large areas with lots of buildings. So if you're wondering exactly where you need to go to use a gun store weapons locker key in Modern Warfare 4, here's what you need to know.

Both buildings look like the one pictured, with the awning above the front entrance, the curved red roof, and the sign featuring a cartoon character. There'll usually be quite a few enemies inside, along with a couple out the front, so be careful. The gun store in Cheongun Village is just over the road from the police station, which is marked on your map. Meanwhile, the gun store in Songdo Wharf is west of the gas station.

Each locker requires a key, so if you have multiple gun store weapons locker keys, you can bring a bunch to open lots of them in one go. Inside, you'll likely find rare weapons and materials.
