Hacking Coca-Cola Machines


I wonder how many Coke machines can be compromised using this simple technique? Performing these actions are illegal so act accordingly…

  1. Uhm. This doesn’t “compromise” coke machines. Pretty much every coke machine menu can be accessed with the 4231 code, and there’s a reason that Coke hasn’t changed it for a long time: it’s harmless. You can’t actually do anything with the menu that you get, other than checking how many cokes are in the machine, how much money is in there, etc. You can’t get money from it, and you can’t get free cokes. Those options are only accessable from inside the coke machine, which, of course, you need a key to get into.


  2. Do you guys actually verify something before you add it? You got people all excited over nothing… Just a stupid menu.. :/


  3. That isn’t true, i’ve read something about this a wile ago.
    4231 is the standard code, but the owner can change it!, so it doesn’t always work.
    With some machines, the with a larger screen you can change the prices!, you can’t change it to 0, but you can make it 0.01 😛
    I’ve tried it on school, and it worked!!

    Sometimes you can hold the button and the cans wil roll out..!


  4. I remember there was a coke machine when i was in college that would give btw 4 and 8 cokes at a time if you held down the dr peper button…probably just a bad catch inside…


  5. As far I rememeber, it was a time when, money in, you could push VERY fast and a lot of time 2 differents button, each given the can it was designed. Doesn’t work on recent machines but some old ones are always available.


  6. i just went to the cock mashine and tried the 4231 code.
    and it worked but it was showing only 4 options “Error”-“Cash”-“return”-“sale”. i tried 4 and it shows the same options.
    now how can i hack to get cheap coke??….


  7. the cock machine? twisted little perv… :p

    I hear a lot of “used tos” and “older”. Nothing new????


  8. Hey ingmar,

    You have to get on the inside of the machine to change the price. That requires a key
    . Trust me, if it was in any way possible to change the price, the Coca Cola company
    would be out a lot of money right now. More info on the exact model of machine you
    claim can give out reduced price Cokes.


  9. Well, in my school i know a person that is assigned to refill some other vending machines, and he also has coke key !! so any1 kn,ow what to do when i’m inside so i can get free cokes without opening it (afther i hacked into it from internal)


  10. hello, what is the right menu to get a free drink (coke) i can only come into the menu with the:
    erro, sale, cash and rtun please send me the right options to get a free coke!!
    THANKSS!!

    Hacking noob


  11. wht are you gay this doesnt do anything but give you sale error and cash.if you wan a real
    chance try a pepsi machine or go to marvel vendors for the schematics nubes


  12. You’re not going to “screw with the menu?”

    Push the buttons you pussy!



  13. Just because you’re capable of figuring out how to steal something more easily – it doesn’t mean you’re not a thief.



  14. Information should be freely accessibly if it does not impede the company’s performance…… this is not hacking. it is merely looking at programming codes which will be available from any vendor upon request. Now, if you benefit from this information with no consideration for it, you should be in jail.


  15. At my old High School only about 5 people, i knew em all, knew how to get free cokes from the machine. We just held down the selection that someone had just bought and 1-2 cokes would come rolling out. Sometimes you would have to press it repetedly.


  16. Hey guys why dont you just buy a Coke Machine key of e-bay that way you an open the door and mess aroud inside the machine !



  17. Wow! OMFG! As if I didn’t know that….why didn;t he pour acid into the return slot or something…now thats a good video to see


  18. i think he should piss in the coin slot on a cold day.
    then it will explode,and coke bottles and money will just fly out.

    i read about it in the anarchist’s cookbook, so it must be real.

    ph34r my sk1llZ


  19. I own vending machines… All that screen is describing is the total sales on the machine, you can even scroll through to see how many each line item sold. You cannot get a free soda or screw the programming!


  20. You can use 4231 to reduce price by doing the following:

    Press 4231
    Press 2
    Press 4
    Press 4 (again)
    Press 4 (again)
    Press 2
    Press 3
    Press 2 (again)
    Use 1 to increase price, 2 to decrease price
    Press 4
    Press 4 (again)
    Press 4 (again)
    Press 4 (again)
    Press the coin return to put the machine back in NOCP (Normal Operating Control Process)


  21. Hey script kiddies, being a common thief is not being a hacker…


  22. Thats not the right code sequence, it should be:
    up up down down left right left right B A start


  23. “natebob Says:”

  26. Doe’s nobody have 55p these days?


  27. want to learn how to hack Atm machines

    Press 2
    Press 4
    Press 4 (again)
    Press 4 (again)
    Press 2
    Press 3

  29. that fakin retard nmust be putt of his league …….i didnt see a sada come out … did u guys see any ?? neway …. somenhess to tell how to do it coz that aint workin ?


  30. see the googlepages site for the content, the new site is now a guide on how to get anything for free


  31. Hi.

    It can be simplier than all this hackin’.
    mayb u might know these neodymium magnets.
    These magnets can be so strong that u might be able to activate
    the relays in the cola-machine. So it is possible to manipulate the
    relay which operates a slot where a can is provided.
    mayb it can be possible to activate the contact(s) in the
    coin-slot to “tell” the machine that a coin was inserted which is
    then actually not the case…

    Electronic and esp. electromechanic circuits and components can
    be manipulated in sometimes very easy ways.

    @home i can persuade my microwave oven to operate with an open
    door
    by manipulating the relevant relay with that kind of magnet
    even thru the ferrous metal case.


  32. I think the firmware is updated, maybe you should descover a new code


  33. get all the money from a cock machin by pressing 432112311


  34. social engeneering is much more efficient and effective. tell the store owner that you put in the correct amount of money, you heard some noises inside, but nothing came up. he will put in a code for a free coke. if you can, try to look at the code and remember it.

    however if you just want to hack, press 4231 and 35 to change the price.


  35. do they still work???

    sad we dont have any vending machines in our country!!
    maybe cause people dont use codes.. they just break the machines and take everything


  36. http://www.youtube.com/watch?v=bUuST6GXvRE

    A dude actually putting in code into a machine and making lots of change come out!

    I have tried this at the local gym’s machine and it worked! The sound of all those coins rushing out certainly drew a lot of attention though.. :-S


  37. haha, super cool how people continue it, but wh would anyone want to hack, just buy the coke!


  38. havent tried coke machines but am willing to swap info on new pepsi machines machines with those who arent full of it


  39. if you really want a free coke & the cash iside the machine just use a pry bar or a hammer & screw driver. Its far less trouble!

    Actually, in Gradius V that will kill you. No seriously. Unless you do it right you will die. Just like playing Slot Machine with a Coca Cola Product.


  41. Actually you only need to press the “select” Button when you want to switch to two player mode.
    Konami Code Now that shit’s Old-School!! 🙂


  42. how do they use the screw to knock the locks out of the drink machines?
