Fallout 76 is full of various little mysteries to uncover and solve as you wander through the Appalachian wilderness. As you explore the area, you’ll come across various items that can be used on the map, one of which is Reuben’s Safe Key. This key is hidden near the starting point of your journey and will lead you to a great place. This guide will show you how to get and use Reuben’s Safe Key in Fallout 76.
How to “Understand What the Key Unlocks” in Fallout 76
Reuben’s Safe Key is a special Fallout 76 item that can only be found on Mr. Gill’s corpse. Reuben Gill was the supervisor of Vault 51, which can be seen by the jumpsuit he is wearing. You can locate Mr. Gill’s body by traveling to the isolated cabin southeast of Vault 76. Immediately after leaving the vault, head to the cabin marked on the map below and you will find Reuben’s body inside the cabin.

Pick up Reuben’s key with the notes he has. This will not only require you to figure out what the key unlocks, but it will also allow you to start learning about shelters. Once you have the key, you will need to head to Vault 51. Vault 51 is located in the far northwest of the map, where the mountains meet. If you’re coming from Vault 76, you can walk north and almost run straight into it.

Once you reach Vault 51, go left of the entrance and you’ll see a small trapdoor you can interact with. Interact with the hatch to enter the Refuge Claims Center. If you’ve started the Vault quest, you can pick up Vault supplies while you’re here. While in the Claim Center, keep an eye out for a large blue and orange supply crate. You can open this container as long as you have Reuben’s security key.
