Call of Duty Black Ops 6 campaign starts at the safehouse where players can upgrade their equipment for upcoming missions. However, there are some places in the mansion with interactable items, including a locked safe.
To unlock this safe, you’ll need the Black Ops 6 safe code, which requires four digits. To obtain these digits, you must complete a series of puzzles. The code will be unique to each player, so sharing a series of numbers isn’t feasible.
Black Ops 6 Safe Locations and Guide
To assist you in cracking the code, we’ve compiled this guide with all the necessary steps to follow. While it’s a lengthy process, it’s manageable and fun—so prepare for a cerebral workout.
How to Crack the Black Ops 6 Safe Codes
There are a total of six puzzles to solve in order to obtain the code for the safe located in the safehouse bedroom. Below are the instructions for solving each puzzle:
Puzzle 1 – Boiler Room

In the safehouse, head down to the basement where the boiler room is located. To activate the boiler, follow the instructions written on a notepad found on a small table.
Steps to Activate the Boiler: (This will trigger the hidden door mechanism tied to the piano)
- On the left, locate the fuel knob. Turn it once to set it in the middle.
- Move to the far right and activate the powering mechanism.
- In the center, you will see the boiler. Turn it off by rotating the dial fully to the left.
If done correctly, an alarm will sound. Ensure the boiler machine isn’t leaking. If it is, you may have made an error in the activation steps.
Puzzle 2 – Piano Puzzle

The piano puzzle is simple: use your blacklight to shine above the piano where a painting hangs. You’ll notice some letters written in Russian, which you should note down.
Using the blacklight reveals arrows directing you to the next piano note. You will find five musical notes: Ми, Рe, Cи, До, and Pe.
Next, interact with the piano and input the combination you discovered in the correct order. Use your blacklight here to determine which key corresponds to each musical note.
Upon correctly entering the notes, a hidden door beside the piano will unlock. Proceed through the door and downstairs to tackle the next puzzle in the Black Ops 6 campaign.
Puzzle 3 – Wordle Keypad

After entering the basement, locate the door with the keypad attached. Interact with the keypad to initiate the next puzzle. This one involves some trial and error, but the game will assist with positioning clues.
Shine the blacklight on the keypad to discover fingerprints. Enter the numbers corresponding to where you see fingerprints.
If a number appears green, its position is correct—do not change it. If a number is marked yellow, swap the positions of those digits.
You have five attempts each time you engage with the keypad. Failure to unlock it requires you to retry the puzzle. After the door opens, proceed to the next area where you’ll find a computer.
Puzzle 4 – Hacking Computer

Interact with the computer to begin a mini-game that involves figuring out words. The code words are represented by numbers displayed at the top of the screen.
Match the digits with the translation reference found at the bottom of the screen. Input the letter corresponding to the numbers to solve this puzzle.
This puzzle’s solution is consistent across all players, with the code words being: BUNKER, HOLDING, ROOM, OPEN. Enter this into the computer to unlock the interrogation room in the basement.
Puzzle 5 – Lockpicking Interrogation Room

After completing the computer puzzle, exit the computer room and move towards the open door on your right. Walk down the hallway until you find a locked door that must be lockpicked.
Engage with the locked door to initiate the lockpicking mini-game. Simply rotate the lockpicking tool while holding the lock pins in place.
There are three pins to stabilize to unlock the door. Once opened, enter the room to retrieve the key located on the table. This key grants access to the final room holding the code.
Follow the signal after obtaining the key to the room it indicates, which will lead you to the Radio Room, where a major puzzle awaits to uncover the safe code.
Puzzle 6 – Radio Tuning and Safe Code

Upon reaching the radio room, interact with the radio to commence the final puzzle. This will present you with an Oscilloscope, where you’ll need to adjust the Amplitude and Frequency of the wave to match a target wave.
NOTE: Turn on subtitles in settings to capture the keywords spoken over the radio. The items mentioned in the radio speech may vary per player.
After solving the radio puzzle, a speech will begin listing various items in the room. The order in which they are mentioned dictates the order of the safe code, so listen carefully.
Find the items referenced in the speech and shine a blacklight on them to determine the safe code digits. Since the locked safe requires four digits, identify four objects in the specified order.
Unlocking the Black Ops 6 Bedroom Safe with the Code and Rewards
Once you’ve determined all four digits, head to the second floor to locate the safe in the bedroom. Enter the digits obtained from the last puzzle to unlock the safe in the Black Ops 6 campaign.
If the safe doesn’t unlock, return to the radio room and reassess the objects and numbers. Each solution is exclusive to you, so sharing passcodes won’t work.
Upon completing this secret quest, you’ll receive an achievement, $1000 to spend within the campaign, and a melee weapon blueprint. These rewards are certainly valuable for your efforts.
Moreover, this quest provides an enjoyable diversion from typical gameplay, allowing players to engage in more than just shooting. Additionally, the melee blueprint is exclusive to those who complete the quest, providing an element of bragging rights.
