Vehicle Bunker Storeroom Key Location and Use: Atomic Batteries

Locate the Vehicle Bunker: The bunker is in southeast Skethermoor, south of the Greenhouse, at coordinates 43.4E, 74.6N. It will be marked on your map if you found a specific letter on the Data Store Room Delta Terminal. Interact with the hatch at the coordinates to enter.

Find the Vehicle Bunker Storeroom Key: Upon entering the bunker, proceed through two doors until you reach a corridor. Save your game. Prepare for a fight with a group of Outlaws. You can attempt to sneak past them, but fighting is recommended. Lure them back to the narrow corridor near the entrance and use explosives to thin their numbers, then finish them off with weapons. Be aware of Outlaw explosives and have a Burn Salve ready. After dealing with the main group, a few Outlaws remain near your objective. Go back to the main room, descend the stairs, and look north behind a tank to find a doorway. Sneak towards this area as you approach. The last few Outlaws (approximately 2-3) will be here. You can either sneak or run and fight when spotted. Continue through the corridor to the barracks. The Storeroom Key is on the bottom bunk bed to the right of the opposite doorway.

Find the Vehicle Bunker Storeroom: Return to the main hall and head southeast to find the storeroom. Unlock it with the key. Save your game before entering, as the room is filled with radiation and will cause damage. Ensure you have at least half health and consider using a Radiation Resistance Potion. Quickly run to the southeast corner to grab the Atomic Battery and then exit immediately.
