those are used to share your points with other players in the game.
- you have to buy the galvaknuckles,
- go prone in front of them,
- knife it,
- then hold x to deposite 1000 points and losse 100 points,
- losing a total of 1100 points
sorry dude. but good try.
i tihkn of it as one person uses the key to put money in the tray, closes it, then the second person opens the key and takes the pints, i know a power pops up when u give money but think of it in real life, one person uses one key to give money, then the receiver opens the box and gets the money. I jave no confidence in this answer, just tossing out a possible answer.
