When all four buttons have been pressed, the cellar will open. To open the cellar door at Raider's Refuge, you'll first need to press four buttons that are all located in or around the POI."

"The four buttons have a set number of possible spawn areas, though the exact location or placement of some buttons can be slightly different.

Four lights above the cellar provide a visual clue that corresponds to the buttons. The buttons have several possible spawn areas and can appear in predictable spots. Common spawn locations include directly in front of the cellar, inside the main structure next to or behind furniture, on the roof near the bell tower and ledges, in the attic accessed by dropping from the roof, along outer walls near generators or panels, and within nearby smaller ruins and basements. When all four buttons are pressed, the cellar opens.
