Hājīn DMZ keys and locked rooms: 35 searchable destinations, how to reach them and what to bring

Find a key you don't recognise? Don't gamble your entire kit trying random buildings. Our updated interactive Hājīn map now includes a 35-entry searchable key finder with the destination grid, building, reported entrance/floor, possible loot, acquisition and a Find area on map control.

We distinguish publisher-verified equipment-kit unlocks from community-observed doors and reported drops. None of these is a guaranteed permanent spawn, a live PvP heat map or a metre-perfect door marker.

See it in the official images.

Publisher-supplied images illustrate the game or feature, not GameOnCue hands-on testing. Captions identify what is shown.

The three keys Activision identifies in progression rewards

Those kits are directly documented by Activision. Community reports place gun-store lockers in Cheongun Village and Songdo Wharf, police armories in several station layouts, and black-market lockers in Hanrim Village or Deadtown. The loot-room location is not a promise by the publisher.

Six mission keys worth understanding

Community research connects Silent Ledger → Counting Room Vault (F4), Shopping Hacks → Coin Mining Den (G6), Critical Extraction → Mirae Electrical Room (F5), Grid Assault → Roze's Highrise Armory (G6), Iron Citadel → Supreme Leader's Bunker Access Card (B6), and Fallen Ember → Reactor DRC Locker (H4). These links are attributed reports, not a guarantee that the mission can be repeated for unlimited key copies. Bring a key you already own; check your mission reward screen.

Three practical key routes

Counting Room Vault — Cheongun Village, grid F4

Find Heavenly Luck Casino. Community routes describe entering the south lobby, moving right into the east wing and following the corridor to the Counting Room, whose outer and inner doors use the appropriate key. This is separate from the large heist drill vault. Reported loot includes safes and weapon crates, not a guaranteed item.

Coin Mining Den — NuriGO West, grid G6

Locate the apartment building east of the westernmost gas station in NuriGO West. Use the south stairwell to the third-floor landing and find the office door. Players report server racks and crafting materials rather than a premium weapon room; plan for close-range stairwell fights.

Reactor DRC Locker — Haneul Reactor, grid H4

The DRC locker is reported underwater in the irradiated Reactor 02 pool. Bring radiation protection, plan the exit and avoid confusing the underwater locker with Reactor 02's separately locked upper control room. Your armory key does not eliminate radiation damage.

Do not confuse keypads with keys

Hanex Bank vaults, the mission's casino drill vault and the Air Base armory's six-digit-code stage are distinct from a named loot locker. Community reports indicate match-specific codes; there is no verified universal code worth publishing. Check in-game notes, card requirements and prompts.

Use the finder as a deployment planner

1. Type the exact key name or tooltip grid into the Key Finder.
2. Read the destination and confidence label. A two-source route is not official proof of every floor or loot container.
3. Mark the key as owned (stored on your own device only) and click Find area on map to centre the parent major POI.
4. Read the area's threat level, choose a short route and an exfil fallback, then deploy with appropriate healing, armour and self-revive.
5. Keep verifying the door prompt and current patch notes. Do not assume a key is reusable or every documented piece of loot is guaranteed.
