Vault 75 Admin Access Card Location And How To Get It

5 October 2026 | 86

Exploring the underground bunkers of the Commonwealth in Fallout 4 often leads players into intricate multi-tiered quests, with Vault 75 presenting a unique navigation challenge. Situated beneath Malden Middle School, this subterranean facility is controlled by hostile Gunner mercenaries who guard its inner security doors. To reach the overseer's office and complete the local questline, acquiring the Vault 75 Admin Access Card is an essential objective.

Finding Vault 75 and Obtaining the First Keycard

Before searching for administrative clearance, players must first enter Malden Middle School and descend into the basement vault area. The initial exploration requires defeating local Gunners to gain entry to the primary testing grounds. To make initial progress into the secure research areas, players need to acquire the Lab Access Card from a Gunner commander in the simulation area.

Once the lab keycard is retrieved, it unlocks sealed security doors leading into the facility's interior laboratory section. Navigating through these corridors brings you closer to the designated combat observation areas. Clearing out surrounding enemies along the way ensures safe travel through the complex.

Locating the Vault 75 Admin Access Card

The Vault 75 Admin Access Card itself is located deep within the laboratory area overlooking the combat training zone. It is carried by a specific Gunner hostile stationed inside the elevated observation room overlooking the diner and combat floor. Eliminating this target allows you to loot the keycard directly from their inventory.

With the admin card secured, return to the main atrium of Vault 75 and head toward the upper level balconies. Use the card to unlock the security door leading directly to the executive office suites. This grant of high-level authority allows access to important lore terminals and valuable endgame loot.

Troubleshooting Access Card Bugs

In some playthroughs, players may encounter an issue where the enemy carrying the required keycard fails to spawn properly. This problem often occurs if the location was partially discovered before the primary vault quest was initiated. Leaving the cell for several in-game days can sometimes trigger a complete area refresh.

Ensuring that the main quest properly registers upon entering the elevator is crucial for enemy spawn triggers. Following the objectives step-by-step prevents progression blockers and ensures all keycard holders load correctly. Completing the section unlocks full access to the overseer's quarters.
