How Event Lockers work at festivals: the 2026 guide

An Event Locker is a personal locker you book online before a festival, then open and re-lock from your phone all day using a locker number and a personal access code. You get the code by email and SMS shortly before your slot. During opening hours you can pop back as often as you like to grab a jacket, stash a purchase, or drop your bag before the barrier. No queue at a wardrobe desk, no paper ticket to lose, nothing to carry through the crowd.

This is the plain-English guide to how they work: sizes, booking, security, the refrigerated Cool Lockers, and why booking online beats hoping a spare one is free at the gate.

What an Event Locker actually is

It is a lockable compartment on a self-contained unit that Volt sets up and runs on site. You do not share it with strangers and you never hand anything over to a staff member. Access is digital: your access code is yours for the whole rental, so you decide when the door opens.

Volt places the units where festival goers need them. Some events have lockers just inside the main gate, some outside it, and camping festivals often add banks in the camp areas too. The Event Lockers service page shows how the setup flexes per event.

What size is an Event Locker, and what fits

The standard Event Locker measures roughly 30 x 30 x 50 cm. That is enough for the day-to-day pile most people want off their hands:

• A rolled-up rain jacket or hoodie
• A small day bag or drawstring bag
• Your wallet plus a powerbank
• Sunglasses, sun cream, a hat, snacks
• A change of clothes or a merch purchase you do not want to carry

One thing to know up front: there is no power outlet inside the locker, so it is for storage, not charging. If your phone is the thing you are worried about, keep it topped up with a Volt charging service and use the locker for everything else.

How booking online works

You book online ahead of the festival rather than gambling on stock at the gate. The flow is short:

1. Book your locker online. Pick a single day or the full festival, depending on what the event offers.
2. Get your locker number and personal access code by email and SMS shortly before your slot starts. The SMS goes to Northern European numbers, with the email as backup, so keep both handy.
3. Open and re-lock during opening hours. Come and go as many times as you want at no extra cost. Grab your sunglasses, drop your jacket when it warms up, stash the vinyl you just bought.

Because the code is tied to your booking, you are not chasing a staff member every time you want in. The door answers to you.

Cool Lockers: the refrigerated option

Cool Lockers are refrigerated Event Lockers, built for the things that should not sit warm in the sun all day. They work the same way as a standard locker, with the same online booking and phone access, but the compartment stays cold.

Festival goers use them for:

• Food and drink you want to keep fresh
• Beer and soft drinks for the camp
• Medication that needs cool storage, like insulin

That last point matters. If you rely on temperature-sensitive medication, a Cool Locker means you are not carrying a warm cool-bag around a field for twelve hours. Availability varies by event, so check the festival's own page for whether Cool Lockers are on the menu.

Is it secure?

Your locker is your own compartment with your own access code, not a shared cubby. The units are monitored daily and sit under cover, and there is on-site support if something goes wrong with the door or your code. Standard sense still applies: keep your code to yourself, close the door properly, and do not leave the locker hanging open when you walk off.

One honest note, the same one every locker service gives: you store your things at your own risk, and Volt is not responsible for items left behind after the festival. Empty it before you leave.

What to do when you are done

At the end of your rental there is no desk to visit and nothing to hand back. Just:

• Take everything out
• Close the door
• Leave it locked

That is it. Do not leave gear inside past the end of the event, because anything left behind is not Volt's to keep safe. Unused rentals are not refunded, so if you booked a locker and never used it, that one is on you.

Why book online instead of turning up and hoping

You can sometimes sort a locker on the day, but there are real reasons to book online first:

• Stock runs out. Popular festivals sell through their locker stock, and the busiest ones fill up before the gates even open. Booking online is how you guarantee you have one.
• The gate price is higher. Booking ahead is cheaper than sorting it on site, if any are left.
• No queue on arrival. Your code is already on your phone, so you walk straight to your locker instead of standing in a line while the set you wanted starts.

The pattern holds across events. You can see how it plays out on real festival pages like Smukfest, Bakkefest, Samsø Festival, and O Days, each with its own locker options, durations, and locations. Prices and opening times change per event, so those pages are where you check the specifics for the festival you are going to.

Frequently asked questions

How do I open my Event Locker?

With the locker number and personal access code sent to you by email and SMS before your slot. You enter the code to open the door, and the same code re-locks it. The door is code-only, nothing to fumble with.

Can I open it more than once?

Yes. During opening hours you can open and re-lock your Event Locker as often as you like, at no extra cost. Come and go all day.

How big is a locker?

The standard size is roughly 30 x 30 x 50 cm. That holds a jacket plus a small bag and your everyday valuables. There is no power outlet inside.

Can I charge my phone in the locker?

No, there is no outlet inside an Event Locker. For power, use a Volt charging service and keep the locker for storage.

What is a Cool Locker?

A refrigerated Event Locker for food and drink, plus medication that needs cool storage like insulin. It books and opens the same way as a standard locker. Availability depends on the event.

What happens if I leave something in it?

Empty your locker before you leave. Volt is not responsible for items left behind after the festival, and unused rentals are not refunded.

The short version

Book online, get your locker number and code by email and SMS, open and re-lock from your phone all day, and empty it before you go. Pick a Cool Locker if you are storing food, drink, or medication. It is a hands-free festival with somewhere safe for your stuff and nothing to carry around a field. See the Event Lockers service page to sort one for your next festival.
