In the scene where Milo sneaks into "the bosses" office, Milo puts the paper with the codes on the keyboard "holder" and slips it in. When he leaves it is clear that he could not possibly take it out without getting caught. So how is it possibly for Milo, or his friend more likely, to enter all of the codes? The movie is good, but that slip-up shows that people will do anything to end the movie the right way.
