Navigating the treacherous island in Sons of the Forest requires more than basic survival skills and crude weaponry. Keycards are essential story items that grant access to high-tech underground bunkers, advanced gear, and crucial story revelations. Among these key items, Maintenance Keycard A is typically the first one players must acquire to progress through locked doors scattered across the map.

Prerequisites Needed Before Searching

Before setting out to locate Maintenance Keycard A, you must first secure the shovel tool. Obtaining the shovel involves exploring deep cave systems that require both the rebreather and the rope gun to navigate safely. Players who track daily gaming news often emphasize prioritizing these cave tools early in a playthrough to prevent unnecessary backtracking.

Once you have crafted proper armor, stored enough food and fresh water, and equipped the shovel, you are ready to head toward the dig site. Venturing into bunker locations without adequate supplies can leave you vulnerable to mutated enemies patrolling nearby areas.

Exact Map Location for Maintenance Bunker A

Maintenance Keycard A is located inside Maintenance Bunker A, situated in the northwestern quadrant of the island. On your GPS tracker, look for a green pulsating point of interest surrounded by golf carts in an open grassy clearing. When you arrive at the designated clearing, you will notice two golf carts parked near a patch of dirt with a surveyor's tripod standing nearby.

Equip your shovel and interact with the loose dirt between the golf carts to begin digging. After clearing away several layers of dirt, a metal hatch labeled Maintenance A will be exposed. Open the hatch and climb down the ladder to enter the subterranean facility.

How to Secure the Keycard Inside the Bunker

Once inside the bunker, proceed down the narrow hallway until you reach an open room on your right. This living space features a kitchen area, a 3D printer, and a cluttered desk containing valuable resources. Look closely at the desk surface next to the laptop to find Maintenance Keycard A resting beside a desk light.

Be sure to grab the keycard along with the 3D printer resin and the firefighter axe located nearby before exiting. Having this card unlocked allows you to access subsequent underground facilities, including the VIP and Guest Keycard locations elsewhere on the island.

Tips for Preparing for Subsequent Bunkers

With Maintenance Keycard A in your inventory, several high-value bunkers across the map can now be opened. These facilities contain powerful weapons, unique outfits, and major narrative clues that reveal the truth behind the island's incident. Always save your game at the bed inside Bunker A before moving on to your next objective.
