Fallout 76 has a lot of secrets and hidden items that you normally would not find unless you randomly stumbled upon them.

The Rusted Key and Alien Blaster weapon are two such items. I’m going to show you where you can get these items, where to use the Rusted Key, and what you get from the room it opens.

Rusted Key Location in Fallout 76

The Rusted Key is not in a landmarked location or marked on the map at all. It is in an open container in the water near a collapsed house.

If you look on the map above, my marker and location is where you can find the Rusted Key. It is in the northern part of the map, northeast of the Eastern Regional Penitentiary.

When you find the container, you’ll see the Rusted Key and Alien Blaster inside. Unfortunately, there isn’t any ammo for the Alien Blaster in or near the container.

You can find ammo for the gun near the Black Mountain Ordnance Works north of the Mothman Museum in the Forest region. 

Now let’s see where to use the key. 

Where to Use the Rusted Key

The place you want to visit is called Freddy Fear’s House of Scares. This is to the east of the Route 66 icon on the map, as you enter the Mire region.

When you reach the location, go to the back of the building and up the stairs. You’ll find a red door that requires the rusted key to open. There are some crafting materials and a safe with some moderately useful items inside.

There is one important item that you can find under a desk, called the Stolen Terminal Passcode. I haven’t found where to use this, but I believe it leads to a bunker somewhere. Scouring forums and the game’s Reddit threads, it doesn’t seem any other players know either, so we’ll update this guide when we find out. 

Now that you know where to get and use the Rusted Key in Fallout 76, you can pick up your own Stolen Terminal passcode.

If you know where it leads or know of any similar secrets, let me know in the comments below.
