I think the keys are actually very simple. If I'm thinking correctly, the keys are specially shaped to fit the circular slot and they have a straight part as some angle on the circle. I think that straight part on the key is what allows the key to fit, and the pin movement is fairly universal from key to key. What I mean is those specific kinds of keys are basically the same besides the angle of the straight piece.

Or I am completely wrong and this was a waste of time.

Oh well, i figured that would not work.

You might be able to just make fake dollars that have the codes in the right spot.

What i mean by codes is the two sequences of numbers and letters on a dollar bill, i believe that is what the machine reads.

i have heard about ways you can do it with your cell phone, by calling the machine but how do you find out what its # is?

Call the machine? wtf are you talking about?

not sure if it would work, but i found it on the net

the movies was complete bs, it was rigged

so all that shit on the internet about those codes "4231" or what ever is a bunch of BS?
