How to hack a Coke machine

Comment: A friend sent this to me. I searched the pages, but didn't see

anything about it!

Want to dazzle your friends with your technical prowess while checking out

the profitability of a vending machine route? Read on. Most Coke machines

built since the late 1990s can be "hacked" with a simple access code. Once

you enter the code, you can find out all kinds of information about the


1. Find a Coke machine that has an LED screen. The small screen will

typically scroll a message such as "Ice Cold Cokes." If the machine's LED

display simply displays the price, the steps below may not work.

2. Enter the access code by using the drink selection buttons. The

default access code is 4, 2, 3, 1, but the buttons aren't numbered. They

will either say nothing or have pictures of "Coke, "Diet Coke," "Sprite,"

and other Coca Cola products on them.

* If the buttons are in a column, button 1 is the top one.

Button 2 is the second one from the top, and so on.

* If they are in a grid or other format, button 1 is the top

left one. Button 2 is the one directly to the right of that, and so on.

3. Scroll through the menu to find out information about the machine.

Example Menu Options

1. EROR: This menu option displays error messages for the machine,

including problems that occurred with the refrigeration system, the

vending mechanism, the bill changer, and the bill validator. To see error

messages, press the select button (button 4) when the display shows EROR,

and then scroll through to see specific errors. Select an individual error

to see more details. Generally if only one type of error has occurred you

won't be able to scroll through other error options.

2. CASH: This option allows you to see the machine's total historical

cash intake, as well as the resettable cash counted for each drink

selection. Press the select button when the the LED display shows CASH.

This will show you the historical cash counted by the machine. Note that

it will include fractions of a dollar, such that if it displays 1352425,

the historical cash count is $13,524.25. Use the scroll buttons (2 or 3)

to navigate to the cash counts for each slot (each beverage selection).

The number displayed will show first the slot number and then the revenue

* This only works for Coke machines, which may sell products such as

Barq's Root Beer, Sprite, Dasani, Evian, Fanta, Fresca, Frutopia,

Powerade, Hi-C, Minute Maid, Nestea, Odwalla, Mr. Pibb, Planet Java, Power

Ade, Seagram's Ginger Ale, Simply Orange, Sparkletts, or Tab in addition

to Coke and Diet Coke.

* In general, these are the only options you can access without having

the door unlocked and open. Different machines may list these options in

somewhat different formats, so experiment a bit to learn what each new one


* If you need to exit the menu quickly (i.e. when you just can't wait

another second to buy an ice cold Coke) press the change (coin return)

button. This will normally quit the menu.

* On some machines, holding the coin return button will display the

machine's inner temperature.

* Vending machine owners or service people have the option to change

the access sequence from 4231 to some other combination of buttons, but

they rarely do. This is probably because having one code makes it easier

for anyone to service all the machines along a route. It may also be

because the information you can access through the external menu with the

door closed is limited and fairly harmless.

* There are several videos available on the internet that show people

using this hack. Many claim to be able to change prices or get a free

drink, but the videos don't actually show them doing so.

* In order to get to the same menu in a machine that sells Pepsi
