All Vault Fragment Locations in Borderlands 4

West side of Stillshore, on a box.

North-east from the Launchpad. Inside a cave accessible via the north side.

At Rosemary’s Reserve, underground. There’s an entrance to the north-west, which you can access by pulling with the grappling hook.

From the entrance to The Pit, look southeast and find the big tree. Go there and look for platforms to climb up, then look up to the east for a grapple point.

Northern side of tunnel through Checkpoint Taupe, go west and there will be a bigger door on the northern side. Once inside Vestal Garrison, go east immediately to another door that leads to a small room. The ECHO Log will be in here, as well as the Vault Key Fragment.

Can be found on a table which is located on the rooftop of the One Pumper building.

Go south across the rocky bridge and then look down to the west to see some water and a glowing object. Drop to the glowing object and look east at the rock face to find the fragment.

Found in the underground section of the Wreck of the Last Great Hop POI and can be reached by opening a vent with the grapple feature.

Use The Reliquary Silo balloon to fly to the north and land on a higher ledge. There will be a cave here and the Vault Key’s inside, next to a dead body.
