The Seeker's Key is a quest item in Remnant 2 that players need to complete the main quest in N'Erud, where players are asked to open the locked door at the Threshold of the Unknown and give access to the ship's core to an NPC named The Custodian.
To unlock the locked door, you need three Seeker's Keys, while you find one right when you enter the N'Erud biome—when you meet The Custodian for the first time, he will task you to find the remaining two Seeker's Keys.
This is where the objective becomes challenging as N'Erud is filled with "not so friendly" mechs, droids, which come in different shapes and forms, otherworldly creatures, and other foes that make the search difficult.
On top of that, there is no clear waypoint or hint on where you can find the remaining two Seeker's Keys. Since without them, you cannot progress the main quest and get to the next biome; we are here to help you with the Seeker's Keys locations.

Where To Find All Seeker's Key In N'Erud In Remnant 2
In Remnant 2, you can find the Seeker's Key in Seeker's Rest, The Putrid Domain, and the Spectrum Nexus domains within N'Erud.
Seeker's Key #1
The first Seeker's Key is locatedin the starting area of N'Erud, which is Seeker's Rest. When you enter N'Erud, keep moving until you reach the main hall, where a ladder opens as soon as you are in the vicinity, leading to a statue holding an orb-like item. Interact with it, and you will obtain the first Seeker's Key.
Seeker's Key #2
The second Seeker's Key is found inside The Putrid Domain, in a room, right after you defeat the domain's main boss.
Here is a map screenshot that shares the exact location of The Putrid Domain:
The domain is full of zombie-like creatures and other deadly beings that we recommend not letting get close to you. The regular enemies have this overgrown purple tumor-like flesh on their chest, shoot it, and you can take them down in one hit.
Seeker's Key #3
Finding the third Seeker's Key is the most challenging task in N'Erud, as you won't be able to find the entrance to the third domain in the central area.
The third Seeker's Key is located in the Spectrum Nexus domain inside a room you can access after defeating the domain's main boss.
Now, to access the domain, after you clear The Putrid Domain, use a Checkpoint Crystal and teleport to Timeless Horizon.
Doing so will give you access to the other part of N'Erud, inaccessible before due to the toxic mist. Now make your way to the Titan's Reach and, eventually, the Spectrum Nexus to get your hands on the third and final Seeker's Key.
