Keys are an important part of the game in Bungie’s extraction shooter, Marathon. Players can find keys hidden all over Tau Ceti IV. You can also buy certain keys, like Lockbox Keys, from CyberAcme after unlocking the right upgrades. The Maintenance Pump Key is different, though.
The Maintenance Pump Key is a crucial item for Runners who want to tackle locked areas in major zones. The key opens a door that is found somewhere in Maintenance on Dire Marsh. There is loot potential associated with unlocking that door, but most players spend ages traversing the map in hopes of finding the place.
You can look at beginner progression tips or go for level boosting if you want to advance in the game without spending hours grinding.
Where to Use the Maintenance Pump Key
The first step would be trying to get rid of as many UESCs as possible once you arrive in the area. Next, look for a minuscule red building that has stairs on the outside. This building is located within the main hangar in Maintenance and has a loading bay next to it with a truck-vehicle parked inside.
Look for the locked Maintenance Pump door. It is not difficult to locate as it has labels on the outside. Equip the Maintenance Pump Key and head towards the door. As you reach the entrance, you will interact with the door automatically to unlock it. This allows you to enter a room inside which you will find numerous caches to look through.
Each of the containers and chests inside the room contains weapons, materials, and other equipment. You can loot as much as you want before exfiltrating out of the game safely. Players also go for buying Marathon equipment for sale if they want to skip all this hard work.
How to Find the Maintenance Pump Key
There are a few ways to get ahold of the Maintenance Pump Key in Marathon.
● Supply drops often contain this key. Keep looting as usual while you wait for the random supply drops to come your way.
● The Maintenance Pump Key can also be picked up during Traxus contracts.
Keys in Marathon are also considered fragile. This means that if you get knocked down by your opponents, any keys you have are destroyed. So it would be beneficial for you to err on the side of caution and steer clear of any enemies in the battlefield once you have got your hands on a key.

The Location of the Maintenance Pump Key Door
Maintenance can be found on the southeastern side of Quarantine on the major Marathon zone, Dire Marsh. Dire Marsh itself is quite mystifying; with floating objects and other strange phenomena all around. Maintenance is quite huge, too. It is also chock-full of UESC enemies.
Conclusion
The Maintenance Pump Key is an important key to have in Marathon. It unlocks a door in Maintenance, found in Dire Marsh, that holds a ton of treasures and lockboxes. Prioritize getting rid of UESCs before you head towards the door and aim to extract safely once you have looted the room.
