The world of Arc Raiders is unpredictable, ruthless, and packed with high-value loot hidden behind locked doors that only the right key can open. Whether you’re pushing deeper into dangerous zones or planning the most efficient extraction route, understanding how keys work is essential for every successful raider. This comprehensive guide breaks down all key types, their locations, and the exact rooms they unlock, helping you maximize every expedition and avoid losing valuable items along the way.
How Keys Work in Arc Raiders
Keys are special consumable items used to open secure doors scattered across the surface. These rooms usually contain rare gear, upgrade materials, or shortcuts that make extraction safer and faster. Before diving into the specifics, here are the core mechanics you should know:
- Keys are consumed on use — once you open a door, the key disappears.
- If you die, you lose the key unless it’s stored in a protected pocket.
- Spawn points are randomized, but some regions have a significantly higher drop chance.
- Keys can be looted from players, earned from missions, crafted, or found in the world.
Understanding these basics will help you plan when to use a key, when to store it, and when it’s worth risking a detour to a locked room.

If a Collector is active, consider postponing your run or rerouting.

Some locked zones are heavily guarded. Approach from high ground or flank when possible.
