If you’ve found the classified records keycard room in Arc Raiders: Riven Tides, you’ll also need to know which door it opens for progression. This guide identifies the specific room within the Port Authority building and details how to navigate the interior to find it quickly.
The classified records room is located inside the Port Authority building.

This facility is a major landmark in the harbor region and can be identified on the map as a large structure on the western side of the docks.

Its location is strategically placed near several extraction points, making it a high-traffic area for raiders looking to secure valuable data.
Once you arrive at the Port Authority building, the most efficient route to the keycard room is through the main access stairs. Head inside and look for the industrial stairwell leading to the upper floors.
Follow these steps to find the room:
-
Go up the stairs to the second level.

-
At the top of the landing, turn immediately to the right.

-
Continue down the short corridor past the storage crates.

-
The keycard room will be directly ahead, marked by a heavy industrial door and a card reader.

Understanding the Room Layout
There are actually two separate access points for the classified records in this building, though they are located in very close proximity to one another. Both rooms require the Riven Tides classified records keycard to unlock.

Once inside, you can find sensitive data records and high-tier loot containers. Because the rooms are situated so close together, it is possible to clear both in a single run if you have multiple keycards or if the doors have already been breached by other raiders.
By heading to the second floor of the Port Authority building and following the corridor to the right, you can easily locate and unlock the classified records rooms.
