Where to use the gun store weapons locker key in DMZ in Modern Warfare 4

The gun store weapons locker key in Modern Warfare 4’s DMZ mode opens lockers in either of two gun stores. The guide identifies their locations and explains how to reach the lockers, which can contain rare weapons and materials.

One store is in Western Cheongun Village, just across the road from the police station; the other is in Northern Songdo Wharf, west of the gas station. Both have distinctive red curved roofs and character signs. Go downstairs to the basement and use a key on each locker in the caged area; enemies may be inside or outside the stores.
