Keys in ARC Raiders follow brutal extraction mechanics. The Blue Gate Confiscation Room Key does not spawn on fixed, guaranteed pedestals. Instead, drops rely on clearing higher-tier combatants within the sector or looting security lockers scattered around logistics outposts.
Veteran squads consistently harvest the key by ambushing heavy mechanized ARC units patrolling the central yards. Heavy drones and tracking sentries possess elevated drop tables for physical keys and security cards. Check small desktop lockboxes inside security guard stations flanking the perimeter fences. Finding the key triggers an immediate dilemma: stash it in your safe container immediately, or risk losing access altogether during a messy firefight.
