Armchair in a tattoo parlor
Code: 3615
This keyboard is hidden next to Helena Novak's body in the back room of the tattoo parlor. To find her, look at the back of the passenger compartment and open the secret compartment.
After trying to pick the lock, the number 1 will appear, and you may think that it is part of the code, and the complete code itself should be one of the tattoo numbers on the computer, but in fact it is not.

Front door lock
Code: 4004
