FN ATC Door

Key-locked Doors are locked rooms found throughout the map that require specific keys to access. These rooms can contain quest-related items needed for tasks, valuable loot, or additional locked containers with supplies and equipment inside. The value of each key-locked room depends on its location and tier. Lower-tier areas usually provide simpler loot and fewer containers, while higher-tier regions can offer more valuable rewards, better supplies, and a greater chance of finding rare items. Because of this, key-locked doors are important points of interest for both task progression and loot runs.
