Rust Master Key Raids: How to Break Into Apartments and What to Grab

What a Master Key costs, how to read room value, and when breaking into an occupied apartment is worth the scrap.

What a Master Key costs, how to read room value, and when breaking into an occupied apartment is worth the scrap.

Apartment rooms in Rust look like tidy little safe-zone lockers, but they leak. Any player holding a Master Key can force a door, get temporary access to an occupied room, and clean out whatever is stored inside. The system pays off only when you follow one rule: never burn a key on a room worth less than the key itself.

Quick answer: Buy a Master Key from the Produce Exchange at Bandit Camp for a base price of 1,000 Scrap, rent any apartment room, open the apartment computer, and pick an occupied Medium or High Value door. Walk up to it, hold interact until temporary access is granted, loot the densest items first, and leave. The key is destroyed after one break-in.

Master Key cost, restock, and the profit math

The Master Key is sold at the Bandit Camp Produce Exchange. Its base price is 1,000 Scrap, and it restocks every 12 real-life hours, not in-game hours. Demand drives the price up, and it has climbed to nearly 3,000 Scrap when stock gets bought out.

UsesOne break-in, then consumed

Because the key vanishes after a single successful raid, the price you paid decides how picky you should be. A cheap key lets you gamble on a decent room. An expensive key needs a confirmed payoff before you commit.

Rent a room first to scout targets

You cannot pick targets without access to the apartment computer, and that means renting a room of your own. The cheapest option is enough if all you want to do is scout. If you forget your room number, ask the apartment NPC again before you start hauling loot around the building.

Room typeRentDaily upkeepBest use
Basement100 Scrap25 Scrap/dayCheapest access, basic storage
Standard200 Scrap50 Scrap/dayMid-tier storage
Penthouse400 Scrap100 Scrap/dayMore expensive storage

Miss a full day of upkeep, and you lose the room, so keep the scrap topped up only if you actually plan to store gear. For pure scouting, a Basement room does the job.

Reading room value on the apartment computer

Once you have rented, the apartment computer lists every room in the building along with its type, storage slots, occupied status, and an estimated value rating. That rating is your filter. Do not raid blind.

Room valueLikely contentsPriority
Null / No ValueEmpty or low-value itemsSkip
LowScrap or light valuablesOnly if the key was cheap
MediumHQM, weapons, rockets, mixed lootWorth checking
HighExplosives or high-tier lootBest target

A High Value tag is the strongest signal the game gives you, but it is not a guarantee of profit. Treat it as the best available read, not a promise of boom behind the door.

How to break into an occupied room

Buy a Master Key at the Bandit Camp Produce Exchange and rent any apartment room so the building’s computer becomes available to you.
Open the apartment computer and scan the room list. Pick an occupied Medium or High Value room that clears the standard for the price you paid on the key.
Walk to that door and hold the interact key to begin the break-in. You cannot move while the unlock runs, so make sure the hallway is clear before you start.
Wait for temporary access to be granted, then open the door. Access is time-limited, so grab the valuable items immediately and ignore the junk.
Leave the room and the building once you have the good loot. The key is already gone at this point, so there is no reason to linger at the door.

You know it worked when the door unlocks and the storage inside opens for you. If players start moving through the hallway mid-unlock, wait it out. Standing frozen at someone else’s locked room is an obvious tell that invites a fight.


Loot priority after the door opens

Temporary access means every second counts. Pull the densest value first and do not stop to sort your inventory. Work straight down this order.

  1. C4 and other explosives
  2. Rockets
  3. Scrap
  4. HQM
  5. Weapons
  6. Components
  7. Armor
  8. Basic resources

One limit to know before you go in: the upkeep storage tied to a room appears to be protected. You can take everything from normal storage, but the rent scrap held for upkeep is likely not stealable.

What raises room value, and what to keep out of yours

The value system does not weigh every item the same way. Explosives and high-tier materials move the rating far more than stacks of stone or metal. The moment your own room tips into Medium or High, it becomes a target for anyone scouting the building.

Stored lootValue impactRisk if raided
Stone / metal fragmentsLowLow
ScrapLow to MediumMedium
HQMMediumMedium-High
WeaponsMediumMedium
RocketsMedium-HighHigh
C4 / explosivesHighVery High
Keycards / armorInconsistentLow-Medium

If you use a room for storage, play around the rating. Keep explosives, rockets, large HQM stacks, big scrap piles, and your best weapons out of apartments entirely. Split loot across multiple rooms so one break-in cannot clean you out, and check your room’s value after each deposit. If it reads High Value, move the expensive stuff back to your base.

Note: Rented rooms count as combat zones even though the wider Apartment Complex is a safe zone, so a break-in can turn into a fight. Treat any apartment as short-term storage, not a vault.


Apartment raiding is simple, but the cost of the key turns it into a decision rather than a reflex. A cheap Master Key rewards aggression against Medium rooms. An expensive one rewards patience and a confirmed High Value target. Scout first, match your standard to what you paid, and skip anything the computer marks as Null.
