So I took the necklace back to Frank and killed the robber. I don't have a datajack or a deck (and neither does Paco) so couldn't access the matrix in the Manager's office. What's the deal with the Ares crate, is there a way to find the code for it?

I thought maybe it had something to do with the note on the Manager's desk, "Oh, I see you ate one too", thinking the code might be 0812 or something like that, but that didn't work.
