Tracking down the Greater Tranquility Maintenance Key is essential if you want to access the restricted maintenance area of the Tranquility Substation in The Outer Worlds 2. This guide quickly walks you through where to find the key, how to reach the hidden location, and what extra loot you can expect to pick up along the way.
How to Get the Greater Tranquility Maintenance Key

Getting the Greater Tranquility Maintenance key is important for accessing the Tranquility Substation at Maintenance Level. This area contains items like the Ryan Powell Pitchball Card, Advanced Decryption Key, and the Black Hat which are well worth it.


To get the maintenance key, take the left path from the location shown in the above map image and keep going until you come across a vent at the lower right. Go inside and you’ll see that it leads to a sort of room which has a ladder in the middle. Climb the ladder and you’ll be led to an area with a big fan, on whose lower left you’ll find a small opening that leads to a room. Go inside and you’ll find a dead body from whom you can loot the key for the Greater Tranquility Station’s maintenance area and a Scholar Cuirass as well. Once you get the access, head back to the station and unlock it.
