Borderlands 4 Vault Key Fragments Complete Guide To Finding The Fragments
Unlocking Primordial Vaults in Borderlands 4 requires players to gather specialized Vault Key Fragments hidden across the planet Kairos. Each major region contains three fragments that must be combined to forge a complete key and access high-tier endgame challenges. Tracking down these elusive items requires strategic exploration, completing map objectives, and navigating difficult terrain.
How to Locate Fragments Using Order Silos
The most efficient strategy for finding fragments is to target and capture Order Silos scattered throughout each zone. Interacting with the central console inside a Silo causes Echo-4 to hack the network and mark the general location of a nearby fragment on your map. Once you enter the marked zone, a four-bar proximity indicator on your HUD will guide you closer to the item.
While capturing Silos provides fast travel points and useful SDU tokens, it is not strictly mandatory for collecting the fragments. Adventurers can discover every fragment simply by exploring hidden caves, rooftops, and subterranean passages independently. Relying on HUD signals allows thorough players to locate key pieces without completing every side objective first.
Finding Key Fragments in The Fadefields
The first set of fragments resides within the starting region of The Fadefields across three distinct zones. In The Howl, players can find a fragment resting on a stone pedestal tucked inside a cave northeast of The Launchpad. Over in Coastal Bonescape, another fragment sits atop a wooden crate behind a building in the Stillshore settlement.
To secure the final piece in Idolator's Noose, head near Rosemary's Reserve to locate a metal pipe with a removable grate. Using your grapple lash opens the entrance to an underground chamber where the fragment is stowed away. Assembling all three allows access to the region's Primordial Vault guardian.
Tracking Fragments Across Carcadia Burn and Terminus Range
Moving into Carcadia Burn, players must search Lopside, Tonnage Peel, and Ruined Sumplands for the next batch of keys. One fragment rests on a table on the roof of the One Pumper Gas Station in Lopside. Another requires pulling open a floor vent with your grapple inside the Wreck of the Last Great Hope at Tonnage Peel to reveal a hidden subterranean cave.
In the dangerous Terminus Range, fragments are tucked into high-altitude areas like Cuspid Climb, The Low Leys, and Windspear. The Low Leys fragment demands climbing over rubble near The Pit to reach an elevated grapple point. The Windspear piece is guarded inside an Order base facility on top of a control room computer terminal. Gathering every piece unlocks powerful combat arenas that reward legendary loot and permanent traversal upgrades.
