During the Bad Blood mission in Japan, Logan and Jean Grey search Shiro’s apartment for his ties to The Hand. Tucked in front of a wardrobe is a keypad that blocks a hidden room, and the game does not simply hand you the number. The keypad carries several fingerprints, so guessing from smudges rarely works on the first try.
Quick answer: Read the code off the bookshelf in the next room. Four black manga volumes are pulled out of order, and their numbers form the four-digit code you enter on the keypad.
Why the fingerprints don’t give you the code
Most locks in the game can be cracked by sniffing out the fingerprints left on the pressed buttons. This one is different because the code was recently changed, leaving prints on several numbers. If you enter a wrong combination, Logan comments that the real code is probably hidden somewhere in the apartment, which points you toward the bookshelf.
How to find the keypad code on the bookshelf
Ignore the neatly aligned volumes entirely. Only the books sticking out matter, and their left-to-right order is the order you type on the keypad.
The code and how to enter it
The four out-of-place volumes read as 1924. Return to the keypad by the wardrobe and punch in the digits in that order. Some playthroughs report the sequence as 1914, so if 1924 is rejected, check the exact spines on your shelf and try that arrangement instead.
How you know the code worked
A correct entry unlocks the wardrobe and opens Shiro’s hidden lair, where he stores his The Hand collectibles. Once Jean and Logan finish looking around, Shiro agrees to help you continue the search for Walter, and the mission moves forward from there.
