Navigating the cannibal-infested wilderness of Sons of the Forest requires players to secure advanced tools and items to survive the dark mysteries of the island. Among the most critical progression items scattered across the map are the security keycards, which grant access to heavily fortified underground facilities. Finding the first major keycard allows you to uncover high-tier loot, valuable story documents, and pathways to subsequent locations.

Essential Tools for the Expedition

Before players can even dream of acquiring this vital piece of security clearance, they must obtain a reliable digging tool. The shovel is absolutely mandatory for unearthing the hidden entrance to the bunker complex where the item is kept. Getting your hands on the shovel requires exploring deep cave networks that demand both the rebreather and the rope gun beforehand.

Attempting to locate the underground complex without these foundational survival items will result in a dead end, leaving you stranded at the site. Ensuring your inventory is packed with proper weaponry and healing supplies is highly recommended before setting out across the island terrain. The hostile environments ahead are frequently guarded by aggressive mutants that can quickly overwhelm unprepared adventurers.

Locating Maintenance Bunker A

Once you are adequately geared up, open your GPS tracker and navigate toward the northwestern quadrant of the island map. Look closely for a designated green point of interest situated relatively close to a local river system and the coastal beach area. Upon arriving at the exact coordinates, you will spot abandoned golf carts and scattered surveying gear indicating past corporate activity.

Equip your shovel and immediately start digging into the conspicuous patch of loose soil located directly between the golf caddies. Persistent digging will eventually uncover a heavy metallic maintenance hatch built into the island floor. Open the hatch carefully and descend the long ladder to safely enter the quiet concrete corridors of the facility below.

Securing the Keycard and Beyond

After reaching the bottom, move down the primary hallway and enter the first open doorway situated on your right side. Inside this small office setup, look carefully on the desk right next to the laptop to claim the valuable security card belonging to Carl Planter. This room also features a functional 3D printer that allows you to craft essential survival resources like flasks and arrows.

Before leaving the underground area completely, make sure to explore the very end of the main corridor to find the heavy firefighter axe. Snagging this powerful utility tool significantly boosts your melee combat capabilities and resource harvesting efficiency. Acquiring this card officially unlocks the necessary security doors within the dining and guest bunkers hidden elsewhere on the island.
