The Gun Store Weapons Locker Key has two supported destinations in MW4 DMZ on Hajin: a shop in Western Cheongun Village and a commercial building in Northern Songdo Wharf. Take the key into either location, reach the green lockers, and use the prompt GUN STORE WEAPONS LOCKER – UNLOCK. One key opens one locker, consumes itself, and awards 375 XP.
Where are the Gun Store Weapons Lockers in MW4 DMZ?
Both compatible lockers are on Hajin, and both areas are classified as Low threat in the available map guidance. The choice is usually practical: use whichever destination is already on your squad’s route, then confirm the exact interaction prompt before spending the key.

| Destination | Building and landmark | Route to the locker | Area detail |
|---|---|---|---|
| Western Cheongun Village | A shop around grid E4 with a counter and a cartoon-mascot poster | Enter the shop, locate the stairwell, and descend to the green lockers in the rear room | Low threat |
| Northern Songdo Wharf | A low commercial building beside a fuel station with a yellow canopy; glass entrance and an “INFORMATION” lobby | Go through the glass doors, find INFORMATION, then take the stairs to the green-walled locker room | Low threat |
Area labels are search guidance rather than guaranteed door coordinates. If a map marker points to the parent area, inspect nearby buildings and landmarks instead of assuming the marker identifies the entrance.
How do I find the Western Cheongun Village locker?
Look for the shop around grid E4, recognizable by its counter and cartoon-mascot poster. The locker room is not on the main sales floor; you must use the stairwell and descend into the back room.

The location is reported as Low threat, but that classification does not guarantee an empty building or eliminate player risk.
How do I find the Northern Songdo Wharf locker?
At Northern Songdo Wharf, use the fuel station with the yellow canopy as your exterior landmark. The target is the neighboring low commercial building with glass doors and an INFORMATION lobby.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errors- Enter through the building’s glass doors.
- Find the lobby marked INFORMATION.
- Take the stairs from the lobby.
- Enter the green-walled locker room and verify the exact unlock prompt.
Some guides spell this area “Sangdo Wharf.” That is a spelling error, not a separate location; Songdo Wharf is the consistent name used for the second destination.

How do I get the Gun Store Weapons Locker Key?
The key is a Rare item. The documented progression routes are the Explosives Equipment Kit at DMZ level 16 and the Trap Equipment Kit at DMZ level 42. Random containers and trains can also produce the key, but those drops are luck-based rather than a dependable unlock path.
Progression sources
- DMZ level 16: Explosives Equipment Kit.
- DMZ level 42: Trap Equipment Kit.
- Random loot: Containers and trains may drop the key without a guaranteed schedule.
How do I equip it correctly?
- At the FOB, open the relevant Survival Kit.
- Move the key into your Stash.
- Equip the key in your deployment loadout.
- Deploy to Hajin with the key active.
A key left only in the Stash cannot be used in the field. Check the loadout before deployment if the item does not appear at the locker.
What happens when I unlock a weapons locker?
Carry the key to either valid store, descend to its locker room, and inspect the interaction text. The key opens one locked gun-store weapons locker per key; opening one consumes the key, leaves the other cabinets locked, and awards 375 XP.

The item is not a universal key for every weapons locker on Hajin. If the prompt names a different lock, cancel the interaction and recheck the complete item name before confirming.
What loot can the locker contain?
Contents vary by opening, so treat reported items as examples rather than a guaranteed loot table. Reported results include a KG-7 Vulcan sniper rifle, Cipher Code Ledger, Control Unit, and Zip Gun.
| Reported item | Reported listed value | How to interpret it |
|---|---|---|
| Cipher Code Ledger | 5,000 | Value reported for that individual opening |
| KG-7 Vulcan | 4,300 | Value reported for that individual opening |
| Control Unit | Not stated | Reported as an example item |
| Zip Gun | Not stated | Reported as an example item |
The key itself has a listed value of 100 in the cited item record. Values and contents should not be read as a promise that every run will produce the same item or price.

Which destination should my squad choose?
Neither destination is established as universally safer: both are marked Low threat, and the available guidance does not provide a reliable PvP ranking. Choose based on navigation and extraction plans.
Quick wins for a faster PC:
Scan for outdated or missing drivers - takes under a minuteDriver Scan →Clear out junk files and repair common Windows errorsFree Scan →- Already near Cheongun: Use the E4 shop and its interior stairwell.
- Routing through Songdo or a fuel station: Use the glass-front building beside the yellow-canopy station.
- Uncertain map pin: Follow the visual landmarks and search the parent area rather than trusting a precise door coordinate.
- Squad carrying one key: Decide in advance which locker room is easier to reach; the key cannot open both destinations.
What should I check before spending the key?
- Confirm the item is the Gun Store Weapons Locker Key, not a similarly named key.
- Ensure it is equipped in the deployment loadout, not merely stored at the FOB.
- Identify the correct building using the counter/poster or INFORMATION-and-fuel-station landmarks.
- Descend to the green lockers and verify the exact GUN STORE WEAPONS LOCKER – UNLOCK prompt.
- Remember that the successful interaction consumes the key.
Frequently Asked Questions
Can one Gun Store Weapons Locker Key open both Hajin locations?
No. Each key is consumed by the first compatible locker you open. The second destination remains locked unless you bring another key.
What if the locker interaction names a different lock?
Do not confirm the interaction. Back out, compare the full prompt with the key’s name, and check that you are at the green gun-store lockers rather than another storage room.

Is “Sangdo Wharf” a separate location from Songdo Wharf?
No. “Sangdo Wharf” is a spelling variation found in one guide. The supported destination is Northern Songdo Wharf.
Can I use the key if it is only in my Stash?
No. Move it from the Survival Kit into the Stash and then equip it in the deployment loadout before entering Hajin.
Are the listed loot values guaranteed?
No. The 5,000 Cipher Code Ledger and 4,300 KG-7 Vulcan figures are values reported for individual drops, not fixed rewards for every opening.
