Last night, you went to a party and someone knocked you out, then grabbed you and locked you in a small room. You're trapped!
After awaking and examining the room, you see that it's a storage locker. On one of the shelves inside the room, there's a small box with a tiny machine inside. It looks like a lock picker, but much more complex. You observe that you need a 3-digit password to use the machine.
Inside the box, there is also a note:
What is the password? Solve it quickly before you die (In 1 or 2 days)!
It's not that hard.
