Vault 75 admin access card

Vault 75 admin access card is a quest item in Fallout 4 that gives access to the admin section of Vault 75 furthering the quest of the same name Vault 75.

Location
It is on a Gunner in the lab overlooking the shooting range.

Inside the "security" section of the vault there is the overseers door, which is obviously locked. Directly across from the overseers door is an area with 3 cubicle looking things (sorry for not having a better description). The right one has a Medkit on the wall, BUT the center one is an actual door to the lab, its just not marked. Go up to the switch on the wall in the center cubicle, open door, and kill everyone inside. The admin card will be on one of the gunners.....

Bugs
This item cannot be removed from your inventory even after completing Vault 75
