ARC Raiders key rooms are not balanced. Some green keys beat epic keys. Some epic rooms are only worth opening at night. Some keys are bait if you use them at the wrong door.

This guide ranks the best locked rooms after the Ribbon Tides update based on tested loot value, weapon drops, blueprint chances, room safety, and day vs night performance.

↖ ARC Raiders Key Room Tier List

Fast rule: if a room can return 100k+ value, pink weapons, Wolf Packs, Snap Hooks, or rare blueprints, it belongs near the top.

↖ Best Key Rooms in ARC Raiders

These are the keys we run first when stash space and time matter.

If you only have one good key, do not waste it on a random run. Pick the right map, door, and raid time.

↖ Dam Battlegrounds Key Room Ranking

Dam has two elite rooms: Control Tower and Staff Room.

↖ Dam Control Tower Is Still S Tier

Run Control Tower if you want consistent value.

It can drop:

• Bobcat 3
• Renegade 3
• Tempest
• Blueprints
• Wolf Pack
• High-value components

Bring Door Blocker + Barricade Kit. Add Jolt Mine if you expect PvP.

↖ Dam Staff Room Is the Best Green Key on Dam

This room punches way above its rarity.

We saw:

• Multiple level 2 weapons
• Wolf Packs
• Photoelectric Cloak
• Rare trinkets
• Blueprints
• 100k+ day raid value

Run it during the day. Night was still good, but day hit harder in testing.

↖ Buried City Key Room Ranking

Buried City has the strongest tested room: Town Hall.

↖ Buried City Town Hall Is the Best Key Room

Town Hall at night is ridiculous.

Best results included:

• Volcano 3
• Multiple Renegade 3
• Multiple Wolf Packs
• Blueprints
• Level 2 and level 3 weapons
• Around 149k inventory value

Enter with empty space. This room overfills bags fast.

↖ Use Residential Master Key at Grandioso Only

The Residential Master Key has multiple doors. Most are bait.

If you find Residential Master, save it for Grandioso, preferably night raid.

↖ Spaceport Key Room Ranking

Spaceport is stacked. Even its weaker keys are playable.

↖ Spaceport Control Tower: Night Only

This room becomes elite at night.

Night loot can include:

• Snap Hook
• Wolf Pack
• Multiple level 2 weapons
• Strong components
• 100k+ profit

Check both entry sides before opening. If one side is already open, you can waste the key.

↖ Warehouse Is a Top Green Key

Warehouse is fast, dense, and profitable.

Best drops:

• Snap Hook
• Tempest
• Multiple level 2 weapons
• Extra key cards
• Security locker loot
• Around 90k+ value

If you find this key, run it.

↖ Trench Tower: North or South?

If unsure: North by day, South by night.

↖ Blue Gate Key Room Ranking

Blue Gate is weaker overall, but Cellar at Ruined Homestead is worth running.

↖ Best Blue Gate Cellar Location

Use the Cellar key near Ruined Homestead / Olive Grove.

It beat Trapper's Glade hard.

Night results included:

• Multiple Vita Sprays
• Blueprint
• Level 2 weapon
• Security locker value
• Around 100k+ value

↖ Confiscation Room Is Night Only

Day Confiscation is bad for an epic key.

Night is better because the loot pool changes. We saw:

• Volcano
• Wolf Pack
• Blueprint
• Better weapon drops

Still, it is not true S-tier. Use it at night only.

↖ Stella Montis Key Room Ranking

Stella Montis has one cracked blue key and one terrible green key.

↖ Archives Key: Run at Night

Day Archives felt weak. Night Archives was completely different.

Night drops included:

• Volcano 2
• Bobcat 2
• Multiple Wolf Packs
• Rare trinkets
• Vita Shots
• Around 147k value

Use Archives at night. Bring two barricades if the door cannot be blocked cleanly.

↖ Security Checkpoint Is the Blueprint Room

This is one of the best rare keys in ARC Raiders.

It can drop:

• Augment blueprints
• Weapon blueprints
• Wolf Pack
• Multiple weapons
• 100k+ value

It is also heavily contested. Bring Door Blocker + Barricade Kit and loot fast.

↖ Assembly Admin Is Almost Always a Skip

Assembly Admin is weak.

It has:

• Low-value containers
• Too many level 1 weapons
• Awkward layout
• Weak profit unless a security locker hits

Do not prioritize it.

↖ Riven Tides Key Room Ranking

Riven Tides added the hotel chain system. The prize is Hotel Room 208.

↖ Riven Tides Hotel Keys Explained

Hotel keys can chain into other hotel keys.

Rooms tested:

• 102
• 107
• 113
• 205
• 208
• 311

Sometimes you get another key. Sometimes you get a volcanic rock. That means the chain is RNG.

↖ Hotel 208 Is S Tier

Room 208 is the best new room after Ribbon Tides.

It can drop:

• Betina 2
• Tempest
• Volcano
• Wolf Pack
• Multiple weapons
• Large multi-floor loot area
• 100k+ value

If you find Hotel Key 208, treat it like an epic key.

↖ Classified Records Beats Secure Storage

This is the weirdest Riven Tides result.

Classified Records is the green room.

Secure Storage is the epic room inside it.

The green room felt better.

If you have both, run both.

If you only have Secure Storage, do not expect true epic-key value.

↖ Crane House Is Bad

Crane House has too many weak breachable containers and not enough premium loot.

Even at night, it only reached around 54k value.

Use it only if you already have the key and are nearby.

↖ Best Day vs Night Key Room Choices

If the room can drop Snap Hooks, Wolf Packs, pink weapons, or rare blueprints, night is usually worth the risk.

↖ Best Keys by Rarity

↖ Best Common Keys

↖ Best Uncommon Keys

↖ Best Rare Keys

↖ Best Epic Keys

↖ Key Rooms to Avoid

If you find these cheap, they can be filler. Do not plan a route around them.

↖ Key Room Safety Rules

Good loot rooms attract players. Play like someone is already outside.

For expensive rooms, go in with:

• Empty bag
• Door Blocker
• Barricade Kit
• Jolt Mine
• Real PvP weapon
• Enough meds to survive a third party

A key room is only profitable if we leave alive.

↖ FAQ

↖ What is the best key room in ARC Raiders?

Buried City Town Hall is the best tested key room, especially at night. It can produce Volcano 3, Renegade 3, Wolf Packs, blueprints, and around 149k value.

↖ Is Hotel Room 208 worth using?

Yes. Riven Tides Hotel 208 is S-tier. It can drop Betina 2, Tempest, Volcano, Wolf Pack, and over 100k value from a common hotel key chain.

↖ Which green key is the best?

The best green keys are Dam Staff Room, Spaceport Warehouse, and Riven Tides Classified Records. Dam Staff Room is the standout because it can hit 100k+ value.

↖ Should I open key rooms during day or night raids?

Use night raids for rooms with premium loot scaling: Town Hall, Spaceport Control Tower, Archives, Blue Gate Cellar, and Confiscation. Use Dam Staff Room during day.

↖ Which key rooms should I avoid?

Avoid Patrol Car Key, Stella Montis Assembly Admin, and Riven Tides Crane House. Also avoid using Residential Master outside Grandioso Apartments.

↖ Summary

The best ARC Raiders key rooms after Ribbon Tides are:

• Buried City Town Hall
• Riven Tides Hotel 208
• Dam Control Tower
• Stella Montis Archives
• Spaceport Control Tower
• Dam Staff Room
• Stella Montis Security Checkpoint
• Blue Gate Cellar at Ruined Homestead
• Spaceport Warehouse
• Riven Tides Classified Records

Biggest lesson: key rarity does not equal loot value.

Some green keys are better than epic keys. Some epic keys are bad unless you run them at night. Some multi-location keys are only good at one door.

Use the right room, bring protection, clear inventory, and pick night raids when the loot pool rewards it. That is how we turn keys into profit instead of donating our bag to the next raider outside the door.
