Gun Store Weapons Lockers are in Cheongun Village and Songdo Wharf. In Cheongun Village, find the anime gun-shop sign west across the road from the Police Station. In Songdo Wharf, search the gun shop west across the road from the Gas Station on the area's north side. Enter the shop and check its basement lockers.
Bring the Gun Store Weapon Locker key and use it on the locked cabinet itself. One key opens one locker; it does not unlock every cabinet in the shop.
Both gun-store locations
The October 29 IGN location guide identifies the following two shops. Both use the same recognizable storefront and a basement layout.
| Shop | Exterior landmark | Interior destination |
|---|---|---|
| Cheongun Village | West side of the village, across the road west of the Police Station; anime character holding a gun on the shop sign | Basement, room on the east side |
| Songdo Wharf | North side of the area, across the road west of the Gas Station | Basement, room on the north side |

Choose the location closest to your current route rather than crossing Hajin just because a guide visits the village first. The shop destination is separate from any requirement to find another key along the way.
Reaching the correct lockers
- Check the key's displayed name before deployment so you are looking for the matching locker type.
- Identify the storefront, enter, and descend to the basement.
- Find the locked Gun Store Weapon Locker cabinets and read the interaction prompt.
- Spend a key on the locker you want, collect the contents, and extract with any gear you intend to keep.

Look for the named cabinet interaction. Screenshot: Activision, via IGN.
The Cheongun footage shows why the room can be confusing: some doors are already open, and there are ordinary containers nearby. An open armory door does not mean every named locker inside has already been looted. Check the cabinets individually. The recorded walkthrough also distinguishes a nearby Dynamic Op keypad from the locker interaction; that keypad is not a substitute for the named key.
Getting keys and deciding how many to bring
Keys can be found as loot. Prima's launch guide also reports keys in the Equipment Kit at DMZ level 16 and Trap Equipment Kit at DMZ level 42. Check those rewards on your DMZ progression track if you have reached the relevant level; a progression reward is different from a guaranteed repeatable enemy drop.
Bring additional keys if you intend to open additional locked cabinets. Do not assume one key opens the room as a whole, or that a random source will provide another key immediately afterward.
What the loot does and does not unlock
The lockers are a way to restock weapons and equipment, but their contents vary. The filmed run showing two weapons and a backpack is an example of that run's loot rather than a fixed package you can expect every time.
Extracted weapons can be used and modified as individual instances. Under the official DMZ Gunsmith rules, repeat purchases of a weapon require its Weapon Manual unlock. A good gun from a locker therefore helps your next deployment without automatically granting permanent access to buy that weapon forever.
