How to Change Vending Machine Prices on Any Brand (2026)

How to change vending machine prices: open the door, press the service or mode button on the control board, scroll to the price menu (PrIC on a Royal, S-P on a Dixie-Narco, "1 PRICE" on a Crane National, the set price switch on an AP), pick a selection or "all", adjust the price and save. Closing the door usually drops the machine back into sales mode, so test one vend before you leave.

Part of our complete guide: how much do vending machines make.

That covers most electronic machines built in the last 30 years. The details change by brand, and the details are where people get stuck: a Dixie-Narco that will not enter set-up because the door switch is in the wrong position, an AP where a selection set to 00.00 starts giving product away, a card reader that still charges the old price. Below are the steps per brand, taken from the manufacturers' service manuals, plus remote pricing through a card reader and the math for deciding how much to raise a price.

Quick reference: the price menu on each brand

Find your brand in the table, then jump to its section. Model numbers are on the serial plate inside the door, usually on the cabinet wall. Each row comes from that maker's manual: Royal GIII, Dixie-Narco SII, AP 7000, Crane National and Vendo V21.

If your machine takes cards through a reader like Nayax, the reader in most setups charges whatever price the machine's controller sends it. Change the price in the machine (or through a supported remote price change), not only in the portal's product list, or the screen and the charge can disagree.

How do you change prices on a Royal 660 or 804 soda machine?

On a Royal with the GIII controller, you press the service mode button, go to PrIC, pick a selection or ALL, and use the selection buttons as arrows. Royal's GIII operation and service manual lays it out like this:

1. Open the door and press the service mode button on the control board.
2. The first four selection buttons now work as ABORT (1), UP (2), DOWN (3) and ENTER (4).
3. Scroll to PrIC and press ENTER. The display shows Pr 1 if the machine is in multi-price mode, or SPrI if it is set to a single price.
4. Use UP or DOWN to pick the selection (PrXX) or ALL, then press ENTER to see its current price.
5. Press UP or DOWN to change it. Holding a button for more than five seconds moves the price ten times faster.
6. Press ENTER to save, or ABORT to back out without saving.

To leave, press the service mode button again or close the door. The controller also exits on its own after about five minutes without a button press.

How do you change prices on a Dixie-Narco 501E or other SII machine?

On Dixie-Narco machines with the SII controller, you press the Set-Up/Audit switch, step to S-P, then press each selection button to raise or lower its price. The SII vender manual (covering DNCB 168, 180, 276, 300, 348, 360, 368, 414, 440, 501 and 600) gives these steps:

1. Open the inner door and press the System Set-Up/Audit switch on the control board. The display reads Hd.
2. Check the door switch. It has three positions and must sit in the center one, or the machine will not enter set-up mode. This is the most common reason a Dixie "ignores" the button.
3. Step through the menu to S-P (Set Price).
4. Press a selection button and its price appears. Hold it to move the price. To switch between going up and going down, release the button and press it again.
5. To give every selection the same price: set the price you want on button 1, then press and hold buttons 3 and 4 together for ten seconds.

Closing the inner door or two minutes of no activity takes the machine out of set-up mode.

How do you change prices on an AP (Automatic Products) snack machine?

On an AP 7000 series, you press "set price" on the mode switch, dial the price with keys 11 and 12, then key in every selection that should sell at that price. From the AP 7000 service and parts manual:

1. Press the "set price" button on the mode switch on the control board. The light above it comes on and the selection display goes blank.
2. Press button 11. The display shows 00.00 and the machine beeps three times.
3. Press 11 to raise the price and 12 to lower it, in 5-cent steps, one beep per step.
4. With the price showing, press the letter and then the number of each selection that sells at that price.
5. Move to the next price and enter those selections. Repeat until every selection has a price.

The manual's warning is worth repeating: any selection left at 00.00 vends for free. When you are done, press the "operate" button on the mode switch or close the door. AP's 6000 and 6600/7600 machines use a similar set-price routine, but check the manual for your exact model before you start.

How do you change prices on a Crane National snack machine?

On Crane National machines (167, 168 and many 4xx and 7xx models), you press "1 PRICE", type the new price on the keypad, and press * to store it. The National programming manual gives three levels:

• Whole machine: press 1 PRICE. The display shows the highest and lowest prices in the machine. Type the new price and press * (TEST START).
• One tray: press 1 PRICE, press the tray letter (for example A), type the price, press *.
• One selection: press 1 PRICE, press the letter and number (A then 1), type the price, press *.

Press # (CODE EXIT) to back out to the standby message. The tray-level option is handy for snack machines where one row is candy and the next is chips.

How do you change prices on a Vendo 621, 721 or 821?

Vendo's V21 controller uses Cost Setting Mode: button 1 scrolls, button 2 enters and saves, button 3 exits. According to Vendo's V21 programming guide, you press the service mode button on the control board, press selection button 2 at the cost setting prompt, scroll with button 1 to a selection (or the option that sets all selections to one price), press 2 to open it, press 1 to change the price, press 2 to save, and press 3 to exit. The V21 accepts any per-selection price from 0.00 to 99.99, according to the 621/721/821 service manual.

How do you change the price on a mechanical or gumball machine?

A mechanical bulk machine has no menu. The price lives in the coin mechanism, so you change the price by changing the mechanism or the part inside it. On a Northwestern Model 60 or Super 60, that is the coin carrier wheel: GumballStuff sells a 50-cent carrier wheel for about $12 that converts a 25-cent mech. Other brands (Oak, Beaver, Eagle) use their own mechanisms, so match the replacement to the brand and model before you order.

Older electromechanical snack and soda machines are in between: on many of them the price is set by switches or settings on the coin mechanism or a price board, not a display menu. Find the coin mech's model number and its manual before you start flipping switches.

Can you change vending machine prices remotely with a card reader?

Yes, if the reader, the machine and the software support it. Nayax calls it a Remote Price Change. Its training guide puts it under Operations, then Machines, then the three-dot menu on the selected machines in the new Nayax Core, and lists the requirements: DEX compatibility, the latest firmware, and product maps fully set up. You can then set prices for a whole machine or bin by bin, and push one change to many machines at once.

If any of those requirements is missing, the price has to be changed at the machine. Before you plan a route-wide price change from your couch, test it on one machine and confirm with a real card vend. Reader fees also eat into a price increase, so check our breakdown of vending machine card reader fees; if you are still choosing hardware, see the best vending machine card readers for 2026.

How much can you raise a price before you lose money on it?

Work it out from the margin, not the price. A higher price makes more per item, so you can afford to sell fewer items and still come out even. The break-even drop is 1 minus (old margin divided by new margin).

Every figure here is an average, and averages hide the building. The revenue calculator lets you plug in the property you are actually looking at and see the range for that type.

Take the second row. At $1.75 you keep $1.15 per bag; at $2.00 you keep $1.40. $1.15 divided by $1.40 is 0.821, so you can sell 17.9% fewer bags and earn the same. A machine selling 100 bags a week can drop to about 82 and break even; if it only drops to 95, you are ahead by 95 x $1.40 minus 100 x $1.15, which is $133 minus $115, or $18 a week from that one row. The costs here are example figures. Plug in your own from your last receipt.

Two rules we would add. First, on a machine that takes coins, keep prices in quarters where you can, so the changer does not run out of nickels and dimes halfway through the week. Second, raise one row or one machine first and give it two to four weeks before you change the rest. Our guide on when to adjust vending prices covers timing, and premium vs budget vending pricing covers which buildings carry a higher price.

Why won't my vending machine save the new price?

Most "won't save" problems come from one of five things:

• Wrong mode. The machine is in single-price mode (a Royal shows SPrI), so per-selection changes do nothing. Switch it to multi-price in the options menu, per your manual.
• Door switch. On a Dixie-Narco SII, the door switch must be in its center position to enter set-up.
• No save step. On a Royal you must press ENTER; on a Crane National, *. Closing the door before saving can lose the change.
• Card reader mismatch. The machine shows the new price but the card is charged the old one, or the reverse. Check the product map in the reader's portal and run one test vend with cash and one with a card.
• A free selection. On an AP, a selection left at 00.00 vends free. After every price change, buy one item from each row you touched.

For problems past pricing, like coins rejecting or spirals not turning, see our vending machine troubleshooting guide.

Getting the price right on a machine that sits in a slow building only helps so much. If the building is the problem, VendBuddy shows you which buildings are worth the walk-in before you move it.

Frequently Asked Questions

Where is the service mode button on a vending machine?

On most electronic machines it is a small push button on the main control board, which sits behind the door near the coin mechanism or on the inside of the door panel. Some brands label it MODE, SERVICE or SET-UP. Dixie-Narco SII machines call it the System Set-Up/Audit switch. If you cannot find it, the board layout drawing in the service manual shows it.

Do I need a code or password to change prices on a vending machine?

Most older Royal, Dixie-Narco, AP, Crane National and Vendo machines only need the door open and the service button pressed. Some newer controllers and bottler-owned machines add a password or a locked menu. If a machine asks for a code you do not have, the seller or the manufacturer's tech support is the place to ask; guessing codes can lock the menu.

Will changing prices erase my sales data on the machine?

Changing a price does not normally clear the machine's sales counters, but some menus sit next to the clear or reset options, so read each prompt before you press enter. If you track sales through a card reader or telemetry, the history lives in the portal and is not affected by a price change at the machine.

Can I set different prices for each row on a snack machine?

Yes. Crane National machines can price a whole tray at once by pressing the tray letter, and AP, Royal, Dixie-Narco and Vendo machines can price each selection separately once they are in multi-price mode. A common setup is one price for candy rows, a higher one for chips and pastries, and the highest for the bottom row of larger items.
