Bank Branch Vault Access is a Rare keycard in MW4 DMZ. It belongs to the Hanex Bank branches on Hajin, and getting into the vault takes three things, a car battery, the card and a code. Below is how we opened the vault of the branch just south of Wolves Stadium, step by step, and what was inside.
- The card spawns inside the bank. Ours lay on the teller counter of the Wolves Stadium branch (G8).
- Put a car battery in the sparking fuse box, then swipe the card at the security door in the red office.
- A note in the lobby gives the first three digits of the vault code. Try the last digit on the keypad until it turns green.
- The vault held two safes with valuables and cash, and a Cipher Code Ledger in the deposit box room.
Where the Bank Vaults Are
There are four Hanex Bank branches on Hajin. One is just south of Wolves Stadium next to the gas station and the UAV tower, grid G8, one is on the main road through Cheongun Village, one is in north Songdo Wharf and one is at the north edge of The Grid, grid G6, across from NuriGO West. The front door of that last one has its own key, the Downtown Branch Lobby Main, but you can also get in at the back. You can spot them by the blue Hanex Bank sign above the front. Every branch has the same setup with a fuse box, a security door and a vault downstairs. This page follows our run at the Wolves Stadium branch, which was a Medium threat area. All three are under the keys layer on our interactive MW4 DMZ map.
How to Get the Bank Branch Vault Access Card
The card spawns inside the bank, so you do not have to bring it. At the Wolves Stadium branch ours lay on the teller counter. In Cheongun Village it lay on the floor behind the teller windows, between loose cash. The same goes for the car battery, which also spawns somewhere in the bank. We brought our own from a gas station, which saves you the search. Every other key and the door it opens is in our MW4 DMZ keys guide.

How to Open the Vault
- Go into the Hanex Bank and pick up the Bank Branch Vault Access card behind the teller counter. Find the car battery in the bank as well, or bring your own.
- Find the sparking fuse box in the side corridor and put the car battery in. This powers the security door.
- Go to the red office with the No Public Access sign and swipe the card at the security door next to it.
- Read the note on the desk in the lobby. It gives the first three digits of the vault code.
- Go back through the security door, take the stairs down to the vault door and try the last digit on the keypad. A wrong code turns red, the right one turns green and the vault opens.

The code changes between matches, so do not copy ours. In our match the note gave 532 and we went up from 5321 until 5327 turned green. Trying the digits in order takes less than a minute.
What Is Inside the Bank Vault
Behind the vault door are two safes and a back room full of deposit boxes, a counter and a few desks. Both safes held valuables and a stack of cash. The deposit box room had loose cash and a Cipher Code Ledger worth $5,000.

From one opening in our own run. Loot is random, so your room can roll differently, and we add every new run of this key. Values are per item, from the in-game tooltips. The loot value adds up every item with a known value and the cash, so it is a lower bound: crafting resources and items without a value are not in it.
The two safes gave an Encrypted Archive, two sets of Ballistic Flight Logs, Infantry Invasion Plans and three Regional Combat Notes, plus $750 and $650 in cash. Together with the Cipher Code Ledger the vault held at least $15,600 in loot, not counting the loose cash stacks. In an earlier run at this branch one of the safes held a Gold Skull, and at the Cheongun Village branch we found Nuclear Program Files and another Cipher Code Ledger, so valuables are the theme in every branch.

Is the Bank Vault Worth It?
Yes. It is quite a sequence of steps, but once you know where everything is you are through it in about two minutes, and for two safes that is time well spent. The vault pays out in stacks of cash and the two safes, and with some luck a safe holds a Gold Bar or a Gold Skull, which are worth a lot. In one of our runs here a safe gave a Gold Skull.
Frequently Asked Questions
Where do you use the Bank Branch Vault Access card in MW4 DMZ?
In a Hanex Bank branch. There are four on Hajin, just south of Wolves Stadium next to the gas station, in Cheongun Village, in north Songdo Wharf and at the north edge of The Grid. The card opens the security door to the back of the bank, and the vault behind it needs a code.
Where do you get the Bank Branch Vault Access card?
It spawns inside the bank itself. At the Wolves Stadium branch ours lay on the teller counter, and in Cheongun Village it lay on the floor behind the teller windows.
What is the vault code for the Hanex Bank in MW4 DMZ?
There is no fixed code. A note in the bank gives the first three digits and you try the last one on the keypad until it turns green. In our match the note gave 532 and 5327 opened the vault, but your match can have a different code.
What do you need to open the bank vault?
A car battery for the sparking fuse box, the Bank Branch Vault Access card for the security door and the code from the note for the vault door. Without power the card does nothing. A car battery spawns somewhere inside the bank too, so you can find all three in the building.
