Unlocking the Safehouse safe in Black Ops 6 is one of the more intricate puzzles in the game’s campaign—but solving it pays off. You'll earn $1,000, the "Case Cracker" melee blueprint, and a trophy/achievement, while also advancing your Safehouse upgrades.
Here’s a full step-by-step breakdown to help you crack the safe and collect your rewards.
Step 1: Restore Power in the Boiler Room
Before accessing the safe, you’ll need to get the boiler up and running.
How to Activate the Boiler:
Locate the Boiler Room
Head to the basement of the Safehouse.
Adjust the Boiler Settings
Turn OFF the water valve completely.
Set the fuel line (left side) to halfway.
Ignite the pilot light (right side) until it stays green.
Turn the water valve back ON to full power.
Check for Power Restoration
Once the boiler stays active, a previously locked door nearby will become accessible.
Step 2: Complete the Piano Puzzle
With power restored, it’s time to unlock the next room using musical notes.
How to Solve It:
Grab the Blacklight
Found in the piano room, on the desk beside the instrument.
Reveal Hidden Notes
Use the blacklight (press Left on the D-pad) to scan the room and find five glowing notes.
Play the Notes in Order
Correct sequence: Mi > Re > Ti > Do > Re
Unlock the Secret Door
A hidden passage at the bottom of the room will open if the notes are played correctly.
Step 3: Crack the Keypad Code
This section plays out like a combination of Wordle and Mastermind.
Keypad Puzzle Instructions:
Find the Keypad
After the secret piano door opens, continue to the hallway and turn right at the intersection.
Use the Blacklight
Scan the keypad to reveal the five most-used digits.
Input and Refine the Code
Trial-and-error the correct sequence using feedback colors:
Green = Correct digit in correct spot
Yellow = Correct digit, wrong spot
Red = Wrong digit
Keep Testing
Continue adjusting until all digits are green and the keypad unlocks the next area.
Step 4: Decode the Computer Cipher
The next room contains a cipher challenge involving numbers and letters.
How to Solve the Cipher:
Locate the Computer
It’s in the room unlocked by the keypad.
Analyze the Number Code
Example: 862 915 (displayed at the top of the screen)
Use the Cipher Table
Match numbers to letters to spell a word (like “BUNKER,” “ROOM,” or “OPEN”).
Unlock the Next Door
Enter the correct decoded word to proceed.
Step 5: Use the Key & Solve the Radio Frequency Puzzle
This step blends exploration and deduction.
Unlock the Door:
Return to the hallway intersection and use the key on the locked door to the right.
Radio Frequency Puzzle:
Tune the Radio
Adjust the:
Amplitude (height of the wave)
Frequency (spacing of the wave) Until it matches the signal tone.
Listen for the Safe Clues
The radio will mention four items, each with an associated number:
Ashtray (8)
Crest (9)
Couch (3)
Chair (5)
Use these to create the 4-digit safe code.
Tip: If you miss one number, try cycling through possible digits to brute-force the code.
Step 6: Open the Safe
Final Steps:
Go Upstairs to the bedroom where the safe is located.
Enter the Code from the radio clues.

Case Cracker melee blueprint
