How to solve the vault safe code in Black Ops 6

As you advance through the campaign of **Call of Duty: Black Ops 6**, you’ll come across various puzzles that can yield valuable rewards. One of the initial challenges involves unlocking a **vault safe** found in one of the **shelter rooms** early in the game.

To access the vault safe, your first task is to locate a **secret room within a bunker** hidden in the shelter. The vault code varies with each playthrough, so we’ve outlined a step-by-step guide for reaching that room and provided potential **code solutions** you may encounter.

### Solving the Boiler Puzzle for Electricity Activation

Your first objective is to head to the **shelter’s basement**, where you’ll find a **malfunctioning boiler**. Based on the documents scattered in the area, follow these steps to repair it and activate the electricity:

1. Turn the **Heater** valve twice.
2. Turn the **Fuel** valve once.
3. Press the **Pilot** button until a yellow light appears.
4. Turn the **Heater** valve twice again.

Once completed, the pilot light should glow **green**, indicating successful power activation for a **hidden door**.

### Resolving the Piano Puzzle for the Secret Door

After activating the electricity, exit the basement and proceed to the room containing **Marshall**. Enter the piano room, where you must activate the ultraviolet light to reveal various symbols on the walls that indicate which piano keys to press.

Approach the piano and interact with it while shining the ultraviolet light over the **top area of the keys** to match the symbols you’ve seen on the wall. If you prefer not to memorize the symbols, here’s the solution:

– **Solution**: 5 – 4 – 2 – 3 – 4

Completing this puzzle will cause the **door** next to the piano to open, granting you access to the bunker where additional puzzles await.

### Unlocking the Bunker Door with the Numeric Keypad

Once you enter the bunker, locate a locked door that requires a code input via a keypad. The trick is to **activate the ultraviolet light** to see which keys have been pressed previously, allowing you to try various **number combinations** for the solution.

The catch is that the **solution is random**, meaning you’ll need to experiment with different numbers. The game will provide feedback indicating whether a number is correct, incorrect, or correctly placed but in the wrong position.

### Hacking the Computer in the Bunker

This puzzle is somewhat similar to the previous one but easier to grasp. Focus on the series of numbers displayed at the top of the computer screen and refer to the bottom, where these numbers are translated into letters that you need to enter.

– **Words to enter**: OPEN, DOOR, BUNKER, ROOM (the order may vary).

### Vault Codes for the Shelter in Black Ops 6

After completing the previous steps, you’ll need to **force a lock** to obtain a key to unlock the final door where the solution lies. Inside, you’ll find a radio that you must tune into for key dialogue that offers hints about the **vault code**.

Pay close attention to what the person on the radio says and look for numbers using the **ultraviolet light** throughout the room, as various items will display numbers in specific locations:

– **1958**: References to a lamp, record player, family crest, and wet carpet.
– **1836**: Mentions involving a lamp, broom closet, and television.
– **7409**: Relates to a guitar, grill, rocket, and calendar.
– **4037**: Includes an iron, curtains, cartoons, and sugar.
– **5024**: Discusses a vinyl record launch, a movie, and an iron.
– **8935**: Refers to an ashtray, family crest, and sofa.
– **2087**: Talks about a love letter, curtain, carpet, and guitar.
– **3196**: Mentions an armchair, calendar, and commemorative flag.
– **7218**: References cereals, a shopping list, and cleaning supplies.

Upon completing these tasks, you’ll receive a **reward** of $1000 for shelter upgrades, a melee weapon project, and the achievement titled “The Puzzles, Mason.”
