Quick Answer: Where Is the Counting Room Vault?
The Counting Room Vault is on the main floor of Heavenly Luck Casino in Cheongun Village, map grid F4.
You need the Epic Counting Room Vault Key to unlock its entrance.
The most straightforward way to obtain the key is by completing Operation Silent Ledger. It can also appear as loot in certain containers elsewhere in the DMZ.
To reach the vault:
- Travel to Heavenly Luck Casino in F4.
- Enter through the main entrance on the southern side.
- Turn right into the corridor with the cages.
- Take the left doorway before reaching the slot-machine area.
- Move through the security offices to the locked wooden door.
- Use the Counting Room Vault Key to unlock it.
Once inside, search the military caches, weapons lockers, and heavy green safe.
Possible rewards include a $25,000 Gold Bar, a $10,000 Sanctioned Assassination List, weapons, armor, and other valuables.
Important: The Gold Bar is a possible find, not a guaranteed reward.
How to Get the Counting Room Vault Key in MW4 DMZ
The Counting Room Vault Key is an Epic key that opens a specific locked room inside Heavenly Luck Casino.
Its in-game description reads:
F4 - Unlocks the counting room's vault on the main floor of the Heavenly Luck Casino within Cheongun Village.
There are two main ways to obtain it.
Method 1: Complete Operation Silent Ledger
Operation Silent Ledger rewards the Counting Room Vault Key.
This story mission takes place at Heavenly Luck Casino and involves breaching a separate basement vault.
Complete the mission, then check your available rewards and FOB Stash before preparing another deployment.
Once you have the Counting Room Vault Key, bring it with you when returning to Cheongun Village.
The key is intended for the casino's main-floor counting room, not the basement vault used during the mission.
Method 2: Find the Key in Loot Containers
The Counting Room Vault Key can also appear in ordinary loot containers.
Two reported locations are:
- Rice Mill, Imjin Farmland: Industrial Locker inside the mill.
- Haksan School: Military Locker.
The Rice Mill is particularly useful to check if you are already searching the area for equipment or supplies.
However, neither location is a guaranteed key spawn.
If the key does not appear, you may need to search other containers or return during another deployment.
Can You Get the Key Without Completing Silent Ledger?
Yes. The Counting Room Vault Key can appear as field loot, so the story mission is not the only possible source.
However, Operation Silent Ledger provides a more predictable way to obtain the key because it is a listed mission reward.
If you already have the key, you can head directly to Heavenly Luck Casino without repeating the mission.
Heavenly Luck Casino Location in F4
Heavenly Luck Casino is located in Cheongun Village, grid F4, on the Hajin tactical map.
Open your Tac-Map and locate the casino before choosing an approach.
The area is marked as High Threat, so be prepared for hostile enemies and possible encounters with other operators.
The Counting Room Vault is on the main floor, near the casino's security and staff offices.
You do not need to enter the basement parking area or reach the vault used during Operation Silent Ledger.
What to Bring Before Entering
A successful casino raid is easier if you prepare your loadout before arriving.
Bring a reliable weapon, enough ammunition, armor plates, and space in your backpack for valuable loot.
Make sure the Counting Room Vault Key is available in your deployment inventory. If possible, place it in a Secure Slot to reduce the risk of losing it after a failed extraction.
Avoid entering with a nearly full backpack. You may need room for valuable documents, weapons, and the Gold Bar.
For help managing your inventory, see our MW4 DMZ Backpack Full guide.
Exact Route to the Counting Room Vault Door
Finding the correct door is easier once you know which landmarks to follow.
Step 1: Enter Through the Casino's Main Entrance
Approach Heavenly Luck Casino from the southern side and enter through the main front doors.
Check for nearby enemies before moving farther inside.
The casino has several connected rooms, so it is easy to take a wrong turn if you start exploring the gambling floor.
Step 2: Turn Right Toward the Caged Corridor
Immediately after entering, turn right.
Look for the corridor containing caged sections.
This is the main landmark for reaching the counting room without searching the entire casino.
Follow the corridor toward the security offices.
Step 3: Take the Left Door Before the Slot Machines
Before reaching the main slot-machine area, take the doorway on your left.
This leads into the security office section.
You should see office furniture, desks, and other equipment as you move through the rooms.
Continue toward the far end of the office area.
Step 4: Find the Dark Wooden Door
Look for a dark wooden door with electronic security hardware, including a keypad and fingerprint reader.
The correct interaction is associated with:
HEAVENLY LUCK CASINO COUNTING ROOM
If you have the correct key, the door should offer an unlock interaction.
Do not confuse this entrance with other secured casino doors or the basement mission vault.
How to Unlock the Counting Room Vault
Once you reach the correct door, follow these steps:
- Approach the Counting Room entrance.
- Confirm that you have the Counting Room Vault Key.
- Interact with the locked door.
- Select the unlock interaction.
- Wait for the door-unlocked confirmation.
- Open the door and enter the secured area.
The door displays a DOOR UNLOCKED confirmation and awards XP when successfully opened.
The Counting Room Vault Key is different from other casino keys, including the Casino Parking Armory Key.
Do You Need a Keypad Code?
No. The Counting Room Vault requires a key, not a numerical keypad code.
The keypad and fingerprint reader are useful landmarks for identifying the correct door, but you do not need to enter a separate code to open it.
If you are trying to use a code, verify that you are standing at the Counting Room entrance.
Other DMZ missions have different access requirements. For example, our MW4 DMZ Broken Resupply walkthrough covers a separate objective involving keypad code 1957.
That code does not open the Counting Room Vault.
Where to Find the $25,000 Gold Bar
One of the most valuable possible finds inside the Counting Room Vault is an Ultra-rarity Gold Bar worth $25,000.
Look for the large reinforced green safe inside the secured vault area.
The safe has an electronic lock and distinctive military-style markings, including a skull symbol and Korean lettering.
How to Search the Gold Bar Safe
After entering the counting room:
- Move through the storage area toward the vault's inner section.
- Locate the heavy green safe.
- Approach its electronic locking mechanism.
- Interact with the safe to open it.
- Inspect the available items.
- Take the Gold Bar if it appears.
The Gold Bar is classified as an Ultra valuable and has a listed value of $25,000.
It can be extracted and sold at the FOB for cash.
Is the Gold Bar Guaranteed?
No. The Gold Bar is a possible reward, but it should not be treated as a fixed spawn.
The containers inside the Counting Room Vault can hold different items between runs.
If the Gold Bar is missing, check the remaining military caches, bags, and weapons lockers before leaving.
Also, do not confuse the Gold Bar listed among Operation Silent Ledger's mission rewards with a Gold Bar found separately inside the Counting Room Vault.
They are different ways of obtaining the item.
Counting Room Vault Loot and Rewards
The Counting Room Vault contains several searchable containers, including military bags, caches, a heavy safe, and weapons lockers.
These can provide valuables, equipment, weapons, and crafting materials.
Valuable Loot
Some of the valuable items you can find include:
| Item | Listed Value |
|---|---|
| Gold Bar | $25,000 |
| Sanctioned Assassination List | $10,000 |
| Degraded Execution Footage | $2,000 |
| Regional Combat Notes | $1,000 |
The Sanctioned Assassination List is a Legendary valuable that can appear in a military cache.
Other documents, including Infantry Invasion Plans, may also be found while searching the room.
These are possible loot items rather than a guaranteed reward package.
Weapons and Armor
Weapons lockers inside the secured area can contain useful combat equipment.
Items worth looking for include:
- REZI 12: Rare shotgun with a listed value of $1,100.
- 2-Plate Helmet Armor Vest: Epic plate carrier valued at $2,500.
- Kastov 762: Assault rifle.
- Armor Plates: Useful for restoring protection.
- Ammo Box: Uncommon Field Upgrade for replenishing ammunition and equipment.
The 2-Plate Helmet Armor Vest provides slots for two armor plates and reduces damage taken from headshots.
If you find one, compare it with your current armor before deciding whether to equip or keep it.
Crafting Materials and Intel
Military caches and bags may also contain crafting ingredients, cash, and intel documents.
Reactive Metals are one example of a material worth checking for.
Some items may be more useful for progression than their immediate sale value.
If you are upgrading weapons and trying to reduce your equipment expenses, see our MW4 DMZ Gunsmith Discount and Weapon Build Costs guide.
Can You Find the Zip Gun Recipe?
The Zip Gun Recipe is another possible reason to search the Counting Room Vault.
It has been found in a Weapons Locker within the secured area.
However, the recipe is not guaranteed to appear on every visit.
If you are specifically searching for it, inspect the available weapons lockers before leaving.
Best Order to Search the Vault
For a quick and efficient loot run, use this order:
- Heavy green safe: Check for the Gold Bar and other valuables.
- Military caches: Look for high-value documents and materials.
- Military bags: Search for additional loot and supplies.
- Weapons lockers: Check for weapons, armor, equipment, and recipes.
- Loose cash and smaller containers: Collect anything useful if you have space.
This order helps you prioritize valuable items without spending too much time searching every corner.
If you find expensive loot early, consider leaving before the risk of another encounter increases.
Counting Room Vault Not Opening? Common Problems
Several different issues can prevent players from reaching or opening the correct room.
1. You Have the Wrong Key
The required item is the Counting Room Vault Key.
Check the name and description in your inventory.
Other casino-related keys do not automatically open the counting room.
2. You Found the Wrong Locked Door
Heavenly Luck Casino contains multiple secured areas.
The Counting Room Vault is on the main floor, while Operation Silent Ledger involves a separate basement vault.
If you are near the basement parking area, return to the main floor and follow the route through the caged corridor and security offices.
3. The Door Says Secured on the Inside
A nearby security door may display:
SECURED ON THE INSIDE - LOCKED
This does not establish that you have reached the Counting Room Vault entrance.
Continue checking the office area for the door identified as Heavenly Luck Casino Counting Room.
4. You Are Looking for a Keypad Code
The Counting Room entrance uses the matching key.
You do not need to solve a separate numerical code puzzle to unlock it.
Check the interaction prompt rather than trying unrelated codes.
5. You Completed Silent Ledger but Cannot Find the Key
Check your FOB Stash, mission rewards, and deployment inventory.
Make sure the key is available before returning to Heavenly Luck Casino.
If you previously carried the key into another deployment and failed to extract, consider whether it was protected in a Secure Slot.
6. Your Backpack Is Full
The vault can contain several valuable items, so limited inventory space can become a problem.
Prioritize high-value loot, useful equipment, and items needed for progression.
Do not drop an important key or crafting ingredient simply to pick up a low-value item.
Is the Counting Room Vault Worth Opening?
Yes, especially if you already have the Counting Room Vault Key and are operating near Cheongun Village.
The room offers several opportunities to collect valuables, weapons, armor, and other useful items.
A Gold Bar worth $25,000 or a Legendary valuable can make a successful raid particularly rewarding.
However, the casino is a High Threat location, and other operators may also be searching it.
Tips for Solo Players
If you are opening the vault alone:
- Bring the correct key before entering.
- Use a reliable weapon and carry spare armor plates.
- Clear immediate threats near the security offices.
- Keep enough backpack space for valuable items.
- Search the safe and major loot containers first.
- Avoid unnecessary fights once you have secured worthwhile loot.
- Leave enough time to reach extraction.
The best decision is not always to empty every container.
If you have already collected valuable loot, leaving safely may be more profitable than continuing to search while other operators approach.
Frequently Asked Questions
Where is the Counting Room Vault in MW4 DMZ?
The Counting Room Vault is on the main floor of Heavenly Luck Casino in Cheongun Village, grid F4. Enter through the main doors, turn right into the corridor with cages, then take the left doorway into the security offices. The locked wooden door is near the far end of the office area.
How do you get the Counting Room Vault Key?
Complete Operation Silent Ledger to receive the Counting Room Vault Key as a mission reward. The key can also appear as loot in certain containers, including an Industrial Locker at Rice Mill and a reported Military Locker at Haksan School. These alternative drops are not guaranteed.
Can you open the Counting Room Vault without completing Silent Ledger?
Yes. If you find the Counting Room Vault Key as ordinary loot, you can use it to open the casino's main-floor counting room without completing Operation Silent Ledger first.
Why won't my Counting Room Vault Key open the door?
Confirm that you have the correct key and are standing at the Heavenly Luck Casino Counting Room entrance. The casino has several secured areas, including a separate basement mission vault. A different door may require another key or access method.
Is there a keypad code for the Counting Room Vault?
No separate keypad code is required. The Counting Room Vault opens with the Counting Room Vault Key. The keypad and fingerprint reader beside the door are visual landmarks, not a numerical puzzle you need to solve.
Is the $25,000 Gold Bar guaranteed?
No. A Gold Bar worth $25,000 can appear in the heavy green safe inside the Counting Room Vault, but the available loot can vary. Other valuables, weapons, and equipment may still make the visit worthwhile.
Can the Zip Gun Recipe spawn inside the Counting Room Vault?
Yes. The Zip Gun Recipe has been found in a Weapons Locker inside the secured area. However, it is a possible loot find rather than a guaranteed reward.
Can you open the Counting Room Vault solo?
Yes. A solo player can unlock the counting room with the correct key. Because Heavenly Luck Casino is a High Threat area, prepare your equipment, manage your inventory, and plan a safe extraction route before entering.
Final Tips
The Counting Room Vault is a worthwhile destination if you want to search several valuable loot containers in one secured area.
The essential steps are simple: bring the Counting Room Vault Key, travel to Heavenly Luck Casino in F4, follow the main-floor security office route, and unlock the correct wooden door.
Once inside, check the heavy green safe for the possible $25,000 Gold Bar, then search the military caches and weapons lockers for additional rewards.
Remember that the Counting Room Vault is separate from the Silent Ledger basement vault, and its loot can change between visits.
Most importantly, prioritize extracting safely with your valuables rather than risking everything to search one more container.
