Introduction: The Key to Unlocking Island Secrets
This remote island conceals numerous mysteries, with many secrets secured behind electronically locked doors. This comprehensive guide details every keycard location in Sons of the Forest and provides proven methods to obtain them.
Sons of the Forest immerses players in a vast, untamed island wilderness brimming with hidden mysteries. Numerous critical secrets are protected behind secured doors. For dedicated explorers determined to uncover every narrative thread Sons of the Forest offers, this guide provides exact locations for all keycards and actionable acquisition strategies.
Sons of the Forest, the acclaimed horror-survival sequel from Endnight Games Limited, features a deeply layered and enigmatic storyline. As the follow-up to The Forest, players are dispatched to locate a missing billionaire, only to become stranded themselves on this treacherous island.
Behind the island’s stunning natural beauty lurk disturbing secrets and dangerous mutated creatures. Survival depends on solving the island’s intricate puzzles, which necessitates locating all access keycards.
The keycards represent just one layer of valuable discoveries in their respective zones. In a game like Sons of the Forest, thorough environmental interaction is essential for uncovering crafting materials, narrative items, and progression-critical equipment.
Below you’ll find precise locations for every Sons of the Forest keycard, accompanied by detailed acquisition methodologies and strategic insights.
Maintenance A Keycard: Your First Major Find
The Maintenance A Keycard, occasionally referenced as the Carl Planter Keycard, is concealed within the underground bunker beneath Maintenance Hatch A in the island’s North-Western quadrant.
Acquiring the Shovel is an absolute prerequisite before attempting to secure the Maintenance A Keycard, as it’s required to excavate the buried hatch entrance. Strategically, this bunker is positioned just north of the cave containing the Shovel, situated between the coastline and mountain foothills—enabling efficient gear collection sequencing.

A pulsating green point-of-interest indicator on your mini-map will activate to signal the keycard’s general vicinity. Additionally, the entrance to Maintenance Hatch A is visually marked by an abandoned golf cart positioned between two surveying tripods—providing reliable landmark navigation.
Once Maintenance Hatch A has been excavated, descend the ladder and proceed through the accessible corridor. The Maintenance A Keycard rests on a desk inside the first open doorway on your right-hand side.
Pro Tips & Common Errors
Strategic Insight: Before heading to the hatch, fully explore the nearby shovel cave for additional resources like rope, cloth, and energy bars. Many players rush and miss these supplies.
Common Mistake: Attempting to dig the hatch with inferior tools wastes time and alerts nearby cannibals. Always secure the proper shovel first.
Navigation Tip: If the green POI disappears (a common bug), use the golf cart landmark and head northwest from the shovel cave approximately 150 meters.
VIP Keycard: Navigating Aquatic Challenges
The VIP Keycard presents more complex acquisition challenges. It’s located within a cave system marked by two parallel-parked golf carts in the extreme North-West map region. Successful retrieval requires the previously obtained Maintenance Keycard, plus specialized diving equipment: a functional rebreather and air tank. The familiar pulsating green mini-map indicator provides directional assistance once more.
The dual golf cart-marked cave leads through a winding tunnel to a vertical hatch requiring descent. Upon reaching the lower level, utilize your Maintenance Keycard on the blue electronic scanner to unlock a nearby secured door. Beyond lies an abandoned laboratory complex adjacent to hydroponic cultivation chambers.
From this point, continue navigating through connecting corridors until reaching a lower sub-level, then traverse the partially flooded laboratory section.
After crossing the aquatic section, another dimly lit corridor emerges. Follow this passage until an open doorway appears on your left. This access point leads upward to the security monitoring station. The VIP Keycard awaits on the desk positioned directly beneath the active security monitor displays.
Advanced Preparation Requirements
Gear Checklist: Beyond the Maintenance Keycard, ensure your rebreather and air tank are at 90%+ durability. Flooded sections can quickly deplete oxygen.
Route Optimization: The most efficient path involves entering from the northern beach, collecting the rebreather from the nearby yacht, then proceeding directly to the golf cart cave.
Threat Management: Mutants frequently patrol the flooded lab area. Consider crafting bone armor beforehand or using stealth movement to avoid combat in confined spaces.
Guest Keycard: Unlocking Luxury Facilities
Similar to VIP Keycard acquisition, obtaining the Guest Keycard requires possessing both the Maintenance Keycard and VIP Keycard—demonstrating the game’s progressive access system.
The Guest Keycard resides within a coastal cave system on the island’s western shoreline. Once more positioned between beachfront and mountainous terrain, this location benefits from the reliable pulsating green mini-map indicator for general positioning. An aged, vegetation-covered golf cart serves as additional visual identification at the cave entrance.
The cave passage connects to another extensive underground bunker network. Progress through the initial corridor, bypass the 3D Printer chamber, and continue until encountering another secured door. Using your Maintenance A Keycard here grants entry to a derelict recreational gymnasium.
To ultimately secure the Guest Keycard, traverse through the gymnasium and adjacent spa facilities until reaching the formal dining area. Ascend the staircase and enter the rear chamber. The Guest Keycard, registered to Arnold Crand, awaits retrieval atop a glass table in this final room.
Efficient Navigation Strategy
Sequence Warning: Many players waste time coming here before obtaining the VIP Keycard. The door simply won’t open without it, despite having Maintenance A access.
Loot Opportunity: The 3D Printer room contains valuable resin and circuit boards—don’t rush past it. These resources are scarce elsewhere.
Shortcut Identification: After the spa, look for a broken wall section on the right that bypasses part of the dining area, saving 20-30 seconds.
Advanced Strategies & Optimization
Optimal Collection Route
For experienced players, following this sequence minimizes backtracking and threat exposure:
- Secure Shovel from northern cave
- Immediately excavate Maintenance Hatch A and obtain Maintenance A Keycard
- Travel to yacht for Rebreather and Air Tank
- Proceed to golf cart cave for VIP Keycard
- Final journey to western cave for Guest Keycard
This route reduces total travel distance by approximately >40% compared to haphazard exploration.
Inventory Management Tips
Keycards don’t consume inventory slots, but essential gear does. Prioritize: weapon, healing items, light source, then diving equipment. Drop excess building materials before embarking.
Threat Avoidance Protocol
Cannibal and mutant patrols increase near all keycard locations. Use elevated terrain for scouting, travel during daylight hours, and consider building temporary shelters near each objective rather than returning to main base repeatedly.
Speedrun Techniques
Advanced players can complete all keycard collection in under 90 minutes by: using zip lines for mountain traversal, skipping non-essential loot, and employing stealth kills instead of prolonged combat.
