The short version
A recent beginner guide places the bunker near the Keep Out area in the bottom-left of the map. The same guide says the keycard can appear randomly and suggests searching vehicles and buildings rather than camping one fixed point.
Use current public reports to plan the bunker approach, keycard search, supplies, and extraction without assuming a fixed spawn or guaranteed reward.
A recent beginner guide places the bunker near the Keep Out area in the bottom-left of the map. The same guide says the keycard can appear randomly and suggests searching vehicles and buildings rather than camping one fixed point.
Loot ordinary houses, shops, and vehicles first. Do not drive toward the Keep Out area without a working defense and recovery option.
A current guide reports no single fixed keycard spawn and specifically calls out cars as worthwhile search points. Search as you travel instead of repeating one unsupported spot.
The current guide reports M as the map key. Mark the bottom-left Keep Out area mentally, then choose fuel, food, healing, and exit thresholds before approaching.
Assume you may need to leave without opening the bunker. The trip should still be survivable if another player, walkers, or a beta change blocks access.
Do not let one more container erase your return margin. Leave while the vehicle, healing, ammunition, and route are still under control.
Current public guidance says the keycard is random. Use a broad search loop until a stronger creator-owned source says otherwise.
The bunker is a late-run objective, not the first stop after spawn. Secure a basic weapon and supplies first.
Food, healing, transport, PvP exposure, and the route back matter even if the door opens.
Recheck the map, controls, and access requirement after updates.
A recent community beginner guide places it near the Keep Out area in the bottom-left of the map. Recheck in-game because the beta can change.
Current public guidance says there is no fixed location. Search vehicles and buildings across a normal supply route.
No. Cars are a reported place worth searching, not a guaranteed keycard source.
Bring a usable weapon, matching ammunition, food, healing, transport or a long-route plan, inventory room, and an exit threshold.
