In ARC Raiders, key cards are essential items for accessing high-value loot rooms. With the Riven Tides update, nine brand-new key rooms were added, and loot pools in several older rooms received adjustments. To help you avoid worthless rooms and efficiently farm ARC Raiders Items and ARC Raiders Coins, this guide provides a side-by-side comparison of every key room during both day and night raids, along with a final ranking.
💡 Whether you're looking to quickly accumulate ARC Raiders Coins or collect rare ARC Raiders Items, choosing the right key can double your efficiency.
Testing Methodology
• Test Environment: Each key room was tested during both a day raid and a night raid.
• Measurement: Loot value was recorded before and after entering the room (basic materials like cloth and plastic were excluded).
• Ranking Criteria: Combined loot value, the frequency of rare items (pink weapons, blueprints, Wolf Packs, etc.), room size, and safety.
Key Room Results & Rankings
♦ S-Tier (Must-Run, Extremely High Value)
1. Dam Control Tower (Blue Key)
• Day Performance: ⭐️⭐️⭐️⭐️
• Night Performance: ⭐️⭐️⭐️⭐️⭐️ (Highly recommended for night raids)
• Typical Profit: 100k+ Coins
• Highlights: Two Snap Hooks, two Wolf Packs, multiple purple weapons, and a ton of grenades. Night performance far exceeds day.

• Day Performance: ⭐️⭐️⭐️⭐️⭐️
• Typical Profit: 100k+ Coins
• Highlights: High-tier weapons (Tempest, Volcano 2, Betina 2) lying on the floor, plus numerous attachments and grenades. Despite being a common key, its loot quality rivals pink key rooms.

♦ B-Tier (Average, Optional)
• Dam Testing Annex (Blue Key): Decent profit, can drop blueprints.
• Dam Surveillance (Green Key): Can drop purple weapons during night raids.
• Buried City Residential Master Key (Green Key, Grandioso basement): Stable profit, but not as good as Town Hall.
• Spaceport Trench Tower (Green Key): South tower is better than north at night; profit ~60–70k Coins.
• Blue Gate Village (Green Key): Small room, quick to loot; profit ~50–70k Coins.
• Blue Gate Communication Tower (Blue Key): Consistent but lacks exciting drops.
• Stella Montis Medical Storage (Green Key): Better at night, can reach 90k+ Coins.
• Stella Montis Security Checkpoint (Blue Key): High chance of augment blueprints, very profitable but dangerous.
♦ C-Tier (Average, Use Only in Specific Situations)
• Buried City JKV Employee (Green Key): Decent profit, small room.
• Buried City Hospital (Blue Key): Extremely small, fast to loot, but loot is mediocre.
• Riven Tides Other Hotel Rooms (311, 102, 107, 113, 205): Can find level 3 weapons on the floor, but overall profit is lower than room 208.
♦ D-Tier (Not Recommended, Low Profit)
• Buried City Other Residential Master Key rooms (non-Grandioso): Low profit, waste of a key.
• Stella Montis Assembly Admin (Green Key): Low profit, not recommended.
• Riven Tides Crane House (Green Key): Low profit, poor value.
• Patrol Car Key: Only a single weapon case — the least valuable key in the game.
Summary
• Day vs. Night: Most key rooms yield higher profits during night raids — especially Spaceport Control Tower, Dam Surveillance, and Blue Gate Seller. Prioritize using your keys at night.
• Best Investments: Spaceport Control Tower (night), Buried City Town Hall, and Riven Tides Hotel Room 208 are currently the three highest-value key rooms.
• Avoid These Traps: Stella Montis Assembly Admin, Riven Tides Crane House, and the Patrol Car Key are extremely low-profit — using them is a waste of a key.
With this information, you can choose your key rooms more strategically, maximize the value of every key, and build up your ARC Raiders Coins and rare ARC Raiders Items much faster.
