Navigating the subterranean modern facilities in Sons of the Forest is essential for unraveling the island's deep mysteries and escaping its terrifying threats. Among the vital items required for key story progression is the Guest Keycard, which opens locked doors inside secure bunkers. Finding this item allows players to access restricted areas containing crucial plot details and late-game equipment.

Prerequisites Needed Before Searching

Before attempting to acquire the Guest Keycard, players must prepare by obtaining specific prerequisite tools. The Maintenance Keycard is strictly required to unlock the initial doors leading into the facility complex. Additionally, equipping a reliable firearm or strong melee weapon is highly recommended due to dangerous mutants lurking inside.

Finding the Bunker Location

The facility holding the keycard is situated on the western side of the island near a green GPS waypoint. Players should look for an obscure cave entrance tucked near a rocky hill surrounding the forested area. Entering the cave leads downward into a modern 3D printer room where the journey deeper into the complex begins.

Navigating to the Nightclub Area

After using the Maintenance Keycard on the double doors in the bunker corridor, follow the linear hallway past the gym area. Continue through the modern recreational zone until reaching a brightly lit, broad staircase leading up to a luxurious lounge and nightclub. The atmosphere changes drastically here, serving as a landmark that confirms you are in the correct location.

Securing the Guest Keycard

Walk toward the back section of the nightclub where several booths surround round glass tables. Locate the body of a deceased VIP slouching over a table covered in stray items and drinks. The Guest Keycard rests directly on the glass surface next to the corpse, ready to be added to your inventory for further exploration.
