The Counting Room Vault is one of the more rewarding locked rooms in Call of Duty: Modern Warfare 4 DMZ, but it sits inside one of the most contested buildings on the map. Heavenly Luck Casino in Cheongun Village draws a constant stream of Operators looking for exactly what you're after, so speed and preparation matter as much as having the right key. Here's everything you need to know to get in, grab the loot, and get out.

How do you get the Counting Room Vault Key?
The Counting Room Vault Key is an Epic-rarity key. Its in-game description confirms it unlocks the counting room's vault on the main floor of Heavenly Luck Casino within Cheongun Village, map grid F4.
Method 1: Complete Operation Silent Ledger
The most reliable way to get the key is by finishing the story mission Operation Silent Ledger. This mission takes place at Heavenly Luck Casino and rewards the Counting Room Vault Key on completion. After collecting it, check your FOB Stash before your next deployment to confirm it's available.
One thing worth knowing: Operation Silent Ledger involves a separate basement vault. The Counting Room Vault Key is for the main-floor counting room, not that basement area. They are two distinct locations inside the same building.
For a full breakdown of all six story missions and their rewards, the MW4 DMZ story missions guide covers everything you need.
Method 2: Find it as field loot
The key can also spawn in loot containers around the map. Two reported locations are:
- Rice Mill, Imjin Farmland – Industrial Locker inside the mill
- Haksan School – Military Locker
Neither location is a guaranteed spawn. If you're already searching those areas for supplies, it's worth checking, but don't build a run around hoping the key appears there.
Where is the Counting Room Vault in MW4 DMZ?
The vault is on the main floor of Heavenly Luck Casino, in the center of Cheongun Village at grid F4 on the Hajin tactical map. You do not need to enter the basement parking area or find the mission vault used during Operation Silent Ledger.

Exact route to the vault door
The route is short once you know the landmarks:
- Approach from the southern side and enter through the main front doors.
- Immediately turn right and pass through the double doors into the caged corridor.
- Follow the corridor and take the first left before reaching the slot machine area.
- Move through the security offices toward the far end.
- Look for a dark wooden door with electronic security hardware, including a keypad and fingerprint reader. The door is labeled HEAVENLY LUCK CASINO COUNTING ROOM.
- Interact with the door and select the unlock option. A DOOR UNLOCKED confirmation appears and awards XP.
No keypad code is required. The fingerprint reader and keypad are visual landmarks for identifying the correct door, not a puzzle you need to solve separately.
What loot is inside the Counting Room Vault?
Once inside, the room contains several searchable containers. The back room holds two Safes that can carry legendary items and significant DMZ cash. Here's a breakdown of what you can find:
| Item | Rarity | Value |
|---|---|---|
| Gold Bar | Ultra | $25,000 |
| Sanctioned Assassination List | Legendary | $10,000 |
| 2-Plate Helmet Armor Vest | Epic | $2,500 |
| Degraded Execution Footage | Rare | $2,000 |
| REZI 12 Shotgun | Rare | $1,100 |
| Regional Combat Notes | Common | $1,000 |
The $25,000 Gold Bar sits in the large reinforced green safe in the back room. It has a distinctive skull symbol and Korean lettering on the electronic lock. The Gold Bar is Ultra-rarity and can be extracted and sold at the FOB.
Other containers in the room include 3 Caches, Military Bags, and Weapons Lockers. The Weapons Lockers can also contain the Zip Gun Recipe, though that too is a possible find rather than a fixed spawn.

Best order to search the vault
Time pressure is real here. Search in this order to prioritize the highest-value items:
- Heavy green safe in the back room (Gold Bar and valuables)
- Military Caches (Sanctioned Assassination List and documents)
- Military Bags (supplies and crafting materials)
- Weapons Lockers (armor, weapons, Zip Gun Recipe)
- Loose cash and smaller containers if backpack space allows
Don't arrive with a full backpack. Leave room for the Gold Bar and at least one or two high-value documents.
How to run the casino safely
Heavenly Luck Casino is marked as a High Threat location and consistently draws multiple squads. The vault room is worth the risk, but the approach matters.
Before entering, check the UAV Towers located east and west of the casino. Activating one gives you a read on nearby enemy positions before you commit to the building.
Once inside, move directly to the vault without exploring the gambling floor. Every extra second in the casino is time another squad can use to set up on you. If you've secured the Gold Bar and a high-value document, leaving immediately is almost always the right call.
For players who'd rather avoid unnecessary PvP entirely, the DMZ truce system guide explains how to propose and accept truces with other Operators, which can turn a potential firefight into a temporary alliance.
Troubleshooting: Why won't the vault open?
A few common issues stop players from getting in:
- Wrong key – Confirm the item is named Counting Room Vault Key. Other casino keys, including the Casino Parking Armory Key, do not work here.
- Wrong door – The basement mission vault and the main-floor counting room are separate. Stay on the main floor.
- Key not in deployment inventory – Check your FOB Stash. If you completed Operation Silent Ledger but didn't bring the key on this deployment, you can't open the vault.
- Backpack full – Not a reason the door won't open, but a full pack means you'll be forced to drop items to pick up loot. Sort your inventory before arriving.
