Method 1. The newest method is the 4,2,3,1 button combination, IT DOES NOT PRODUCE A FREE SODANOR CAN IT CHANGE PRICES. This one only works n the new coke machines with the large ractangle buttons. You can check the temperature, how many sodas were sold, how much money the machine has in it, etc. But you can not get a free soda in anyway.

Method 2. The ol' stringed coin trick, yes this work, drilla hole with the smallest drill bit you have, and tie a string to it. Place the quarter in the slot, and yank it out when its about 3 inches in.
This only works on older machines or machines without the locking device.

Method 3. Saltwater. Pouring saltwater in the coin slot while holding down the preferred soda produces the soda.

Method 4. VERY old machines only. Hold down the button of the soda you want, have somebody unplug the machine and replug it. Free soda for you!

Method 5. Taped dollar. If you put packaging tape on the white strips of the dollar (IF YOU GO OVER HTE WHITE STIRPS IT WILL NOT WORK) you can easily pull the dollar out when its fully scanned. Do not pull to slow or to hard, use a nice firm grip and pull. You should hear a click.

Method 6. This one is also for slightly older machines. Cut a notch right below the one on the left side of the dollar. When you place the dollar in the machine, make sure the notch is closest to you, it goes in last, if done correctly, it will work.

METHODS 5&6 WILL WORK ON CHANGE MACHINES

Another note: I have tested all of these methods and they all work, if I find anymore I'll post them.

Once again, if you get arrested for doing this, its not my fault, I warned you.

Here is an image, feel free to redraw one, if you want.

Err... The debug combination DOES work if the internal switch is flipped, which it rarely is. I got it to work yesterday in front of dollar general.

I have done it on 10+ machines and it's worked every time.

For number 6, pictures, pl0x.

I meant for changing prices, but whatever.

Oh, my bad I thought you just meant getting into the D-Bug menu.

Yeah .

Well, i just drilled a hole through washingtons eye.

Got some dental floss.

Gonna try.

For some reason, i doubt it will work, i mean.. i saw this work in like.. a 1940's cartoon.

But whatever, hope it works.

some pictures would be nice. "older machines" doesnt rly cover it.
overall, its good.

It doesn't in newer ones. they have little metal or plastic things that catch your coin like this:

And the conveyor belt.

And that kids, is how the sperm enters the Vagina, thus impregnating the female.

Really, just about any from 1990 and above.

Oh, and NobodY, don't you know that all vending machines parts have inspiration from human reproduction?

Eh, mine are pretty ****ing old, i tried it today, but the whole i drilled into it made the a tiny nick that stuck out, so the quarter wouldnt go in.
