Trying to locate all Vault Key Fragments in Borderlands 4? Before you can delve into the deep Vaults beneath Kairos, you must first locate 9 Vault Key Fragments scattered throughout the various zones of Borderlands 4 . These are often hidden in places far off-the-beaten path, but luckily, we’re here to spill all the beans.
This guide provides a full list of all Vault Key Fragments in Borderlands 4 , ensuring that you’ll find each fragment quickly and won’t waste any time in your quest for bigger and better loot.

All Borderlands 4 Vault Key Fragment locations
There are nine Vault Key Fragments in total hidden throughout The Fadefields, Terminus Range, and Carcadia Burn. This embedded map shows all of their locations, which we’ll go into with greater detail below.
In this guide:
- The Fadefields Vault Key Fragments
- Terminus Range Vault Key Fragments
- Carcadia Burn Vault Key Fragments
NOTE: If you’ve already found all 9 of these Vault Key Fragments, then you can go ahead and access the vaults themselves. Refer to our guide on the locations of all three Primordial Vaults for more information!
The Fadefields Vault Key Fragments
Coastal Bonescape Vault Key Fragment : You can find this in the southwest corner of the region near the Stillshore point of interest. Head towards the building with the slow-spinning fan and then check the crate that’s located on the back balcony. The fragment is there.

Be on the lookout for the crate marked “32.” |Image credit:IGN/2K
The Howl Vault Key Fragment : This one’s in a cave southwest of Ardor’s Bounty and northwest of The Launchpad. Enter from the north and you’ll find the key on a small pedestal amongst the rocks.

When in doubt while searching for any of these fragments, always keep an eye out for shiny golden rocks. |Image credit:IGN/2K
Idolator’s Noose Vault Key Fragment : From the Rosemary’s Reserve point of interest, go northeast of Idolator’s Noose until you can spot Propaganda Tower. Turn southeast and notice the wall vent. Pull it off and explore the bunker it conceals; the fragment is located on a Ripper corpse next to a Marcus Bobblehead.

Rip this vent free with your grapple to find the fragment. |Image credit:IGN/2K
Terminus Range Vault Key Fragments
Cuspid Climb Vault Key Fragment : After unlocking The Reliquary silo, use the balloon to fly north towards the outcropping rock bridge that extends from a mountain near the waterfall. Land on this bridge, enter the nearby cave, and keep going upwards until you find the fragment on a corpse.

See that rocky bridge in the distance with the trees on it? That’s where you’ve got to fly towards. |Image credit:IGN/2K
The Low Keys Vault Key Fragment : This fragment is near the centre of Terminus Range, near The Pit point of interest. Go to the curly white tree that has another tree beneath it with purple petals, and start climbing the nearby rocks. You’ll eventually reach a Grapple Node; keep climbing up until you reach the fragment.

It’s quite the striking dead tree, isn’t it? And the fragment’s located up those rocks right next to it! |Image credit:IGN/2K
Windspear Vault Key Fragment : You can find this fragment inside The Vestal Garrison, which is southwest of The Nightcap safehouse. Go inside the base, and on the first floor, turn left to enter the first door you can see. The fragment is on a table in the room, which is filled with a whole bunch of computers.

The Vestal Garrison’s packed with mobs, so get your guns ready. |Image credit:IGN/2K
Carcadia Burn Vault Key Fragments
Lopside Vault Key Fragment : Go north of The Yawning Yard point of interest until you come to a petrol station with a “One Pumper” sign outside. There’s a Grapple Node above you; use it to go up to the second level where the fragment sits on a table.

Get on top of this station and search for the long dining table with the chairs. |Image credit:IGN/2K
Tonnage Peel Vault Key Fragment : This fragment’s in the Wreck of the Last Great Hope point of interest. Technically, however, it’s not in the wreck itself - it’s underneath the shipwreck’s southeast portion. Enter via the south entrance and then proceed until you reach a red light. Enter the vent on the ground to find the fragment’s hiding place.

Ride through here and keep going until you reach the dead end with the blinking light. |Image credit:IGN/2K
Ruined Sumplands Vault Key Fragment : Go to the beach northeast of the Hull’s Handbasket point of interest. There’s a small pool of water here; turn right to find the pedestal holding the fragment.

To the left of the fragment’s resting spot is an enclave filled with water. |Image credit:IGN/2K

All 75 Arc Raiders Blueprints and where to get them
These areas have the highest chance of giving you Blueprints

Looking for more Arc Raiders Blueprints? It’s a special day when you find a Blueprint, as they’re among the most valuable items in Arc Raiders. If you find a Blueprint that you haven’t already found, then you must make sure you hold onto it at all costs, because Blueprints are the key to one of the most important and powerful systems of meta-progression in the game.
This guide aims to be the very best guide on Blueprints you can find, starting with a primer on what exactly they are and how they work in Arc Raiders, before delving into exactly where to get Blueprints and the very best farming spots for you to take in your search.
We’ll also go over how to get Blueprints from other unlikely activities, such as destroying Surveyors and completing specific quests. And you’ll also find the full list of all 75 Blueprints in Arc Raiders on this page (including the newest Blueprints added with the Cold Snap update , such as the Deadline Blueprint and Firework Box Blueprint), giving you all the information you need to expand your own crafting repertoire.
In this guide:

- Full Blueprint list: All crafting recipes
- Where to find Blueprints in Arc Raiders Blueprints obtained from quests Blueprints obtained from Trials Best Blueprint farming locations

What are Blueprints in Arc Raiders?
Blueprints in Arc Raiders are special items which, if you manage to extract with them, you can expend to permanently unlock a new crafting recipe in your Workshop. If you manage to extract from a raid with an Anvil Blueprint, for example, you can unlock the ability to craft your very own Anvil Pistol, as many times as you like (as long as you have the crafting materials).
To use a Blueprint, simply open your Inventory while in the lobby, then right-click on the Blueprint and click “Learn And Consume” . This will permanently unlock the recipe for that item in your Workshop. As of the Stella Montis update, there are allegedly 75 different Blueprints to unlock - although only 68 are confirmed to be in the game so far. You can see all the Blueprints you’ve found and unlocked by going to the Workshop menu, and hitting “R” to bring up the Blueprint screen.
It’s possible to find duplicates of past Blueprints you’ve already unlocked. If you find these, then you can either sell them, or - if you like to play with friends - you can take it into a match and gift it to your friend so they can unlock that recipe for themselves. Another option is to keep hold of them until the time comes to donate them to the Expedition.

Note: The missing Blueprints in this list likely have not actually been added to the game at the time of writing, because none of the playerbase has managed to find any of them. As they are added to the game, I will update this page with the most relevant information so you know exactly how to get all 75 Arc Raiders Blueprints.
Where to find Blueprints in Arc Raiders
Below is a list of all containers, modifiers, and events which maximise your chances of finding Blueprints:
- Certain quests reward you with specific Blueprints .
- Completing Trials has a high chance of offering Blueprints as rewards.
- Surveyors have a decent chance of dropping Blueprints on death.
- High loot value areas tend to have a greater chance of spawning Blueprints.
- Night Raids and Storms may increase rare Blueprint spawn chances in containers.
- Containers with higher numbers of items may have a higher tendency to spawn Blueprints. As a result, Blue Gate (which has many “large” containers containing multiple items) may give you a higher chance of spawning Blueprints.
- Raider containers (Raider Caches, Weapon Boxes, Medical Bags, Grenade Tubes) have increased Blueprint drop rates. As a result, the Uncovered Caches event gives you a high chance of finding Blueprints.
- Security Lockers have a higher than average chance of containing Blueprints.
- Certain Blueprints only seem to spawn under specific circumstances: Tempest Blueprint only spawns during Night Raid events. Vulcano Blueprint only spawns during Hidden Bunker events. Jupiter and Equaliser Blueprints only spawn during Harvester events.

Raider Caches, Weapon Boxes, and other raider-oriented container types have a good chance of offering Blueprints. |Image credit:Rock Paper Shotgun/Embark Studios
Blueprints have a very low chance of spawning in any container in Arc Raiders, around 1-2% on average. However, there is a higher chance of finding Blueprints in particular container types. Specifically, you can find more Blueprints in Raider containers and security lockers.
Beyond this, if you’re looking for Blueprints you should focus on regions of the map which are marked as having particularly high-value loot. Areas such as the Control Tower in Dam Battlegrounds, the Arrival and Departure Buildings in Spaceport, and Pilgrim’s Peak in Blue Gate all have a better-than-average chance of spawning Blueprints somewhere amongst all their containers. Night Raids and Electromagnetic Storm events also increase the drop chances of certain Blueprints .
In addition to these containers, you can often loot Blueprints from destroyed Surveyors - the largest of the rolling ball ARC. Surveyors are more commonly found on the later maps - Spaceport and Blue Gate - and if one spawns in your match, you’ll likely see it by the blue laser beam that it casts into the sky while “surveying”.
Surveyors are quite well-armoured and will very speedily run away from you once it notices you, but if you can take one down then make sure you loot all its parts for a chance of obtaining certain unusual Blueprints.
Blueprints obtained from quests
One way in which you can get Blueprints is by completing certain quests for the vendors in Speranza. Some quests will reward you with a specific item Blueprint upon completion, so as long as you work through all the quests in Arc Raiders, you are guaranteed those Blueprints.
Here is the full list of all Blueprints you can get from quest rewards:
- Trigger Nade Blueprint: Rewarded after completing “Sparks Fly”.
- Lure Grenade Blueprint: Rewarded after completing “Greasing Her Palms”.
- Burletta Blueprint: Rewarded after completing “Industrial Espionage”.
- Hullcracker Blueprint (and Launcher Ammo Blueprint): Rewarded after completing “The Major’s Footlocker”.
Alas, that’s only 4 Blueprints out of a total of 75 to unlock, so for the vast majority you will need to find them yourself during a raid. If you’re intent on farming Blueprints, then it’s best to equip yourself with cheap gear in case you lose it, but don’t use a free loadout because then you won’t get a safe pocket to stash any new Blueprint you find. No pain in Arc Raiders is sharper than failing to extract with a new Blueprint you’ve been after for a dozen hours already.

One of the best ways to get Blueprints is by hitting three stars on all five Trials every week. |Image credit:Rock Paper Shotgun/Embark Studios
Blueprints obtained from Trials
One of the very best ways to get Blueprints is as rewards for completing Trials in Arc Raiders. Trials are unlocked from Level 15 onwards, and allow you to earn rewards by focusing on certain tasks over the course of several raids. For example, one Trial might task you with dealing damage to Hornets, while another might challenge you to loot Supply Drops.
Trials refresh on a weekly basis, with a new week bringing five new Trials. Each Trial can offer up to three rewards after passing certain score milestones, and it’s possible to receive very high level loot from these reward crates - including Blueprints. So if you want to unlock as many Blueprints as possible, you should make a point of completing as many Trials as possible each week.
Best Blueprint farming locations
The very best way to get Blueprints is to frequent specific areas of the maps which combine high-tier loot pools with the right types of containers to search. Here are my recommendations for where to find Blueprints on every map, so you can always keep the search going for new crafting recipes to unlock.

Image credit:Rock Paper Shotgun/Embark Studios
Dam Battlegrounds
The best places to farm Blueprints on Dam Battlegrounds are the Control Tower, Power Generation Complex, Ruby Residence, and Pale Apartments . The first two regions, despite only being marked on the map as mid-tier loot, contain a phenomenal number of containers to loot. The Control Tower can also contain a couple of high-tier Security Lockers - though of course, you’ll need to have unlocked the Security Breach skill at the end of the Survival tree.
There’s also a lot of reporting amongst the playerbase that the Residential areas in the top-left of the map - Pale Apartments and Ruby Residence - give you a comparatively strong chance of finding Blueprints. Considering their size, there’s a high density of containers to loot in both locations, and they also have the benefit of being fairly out of the way. So you’re more likely to have all the containers to yourself.
Buried City
The best Blueprint farming locations on Buried City are the Santa Maria Houses, Grandioso Apartments, Town Hall, and the various buildings of the New District . Grandioso Apartments has a lower number of containers than the rest, but a high chance of spawning weapon cases - which have good Blueprint drop rates. The others are high-tier loot areas, with plenty of lootable containers - including Security Lockers.
Spaceport
The best places to find Blueprints on Spaceport are the Arrival and Departure Buildings, as well as Control Tower A6 and the Launch Towers . All these areas are labelled as high-value loot regions, and many of them are also very handily connected to one another by the Spaceport wall, which you can use to quickly run from one area to the next. At the tops of most of these buildings you’ll find at least one Security Locker, so this is an excellent farming route for players looking to find Blueprints.
The downside to looting Blueprints on Spaceport is that all these areas are hotly contested, particularly in Duos and Squads. You’ll need to be very focused and fast in order to complete the full farming route.

Blue Gate
Blue Gate tends to have a good chance of dropping Blueprints, potentially because it generally has a high number of containers which can hold lots of items; so there’s a higher chance of a Blueprint spawning in each container. In my experience, the best Blueprint farming spots on Blue Gate are Pilgrim’s Peak, Raider’s Refuge, the Ancient Fort, and the Underground Complex beneath the Warehouse .
All of these areas contain a wealth of containers to loot. Raider’s Refuge has less to loot, but the majority of the containers in and around the Refuge are raider containers, which have a high chance of containing Blueprints - particularly during major events.
Stella Montis
On the whole, Stella Montis seems to have a very low drop rate for Blueprints (though a high chance of dropping other high-tier loot). If you do want to try farming Blueprints on this map, the best places to find Blueprints in Stella Montis are Medical Research, Assembly Workshop, and the Business Center . These areas have the highest density of containers to loot on the map.
In addition to this, the Western Tunnel has a few different Security Lockers to loot, so while there’s very little to loot elsewhere in this area of the map, it’s worth hitting those Security Lockers if you spawn there at the start of a match.
That wraps up this primer on how to get all the Blueprints in Arc Raiders as quickly as possible. With the Expedition system constantly resetting a large number of players’ Blueprints, it’s more important than ever to have the most up-to-date information on where to find all these Blueprints.
