How keys work
- Keys open special loot rooms; each key's description names a map grid square for its door.
- Grid letters run A to J west to east; numbers run 1 to 9 north to south.
- Keys show a value of 100 and sell for 100 at the FOB.
- Without the key a door reads LOCKED; carrying it shows UNLOCK, then OPEN DOOR.
- Most key unlocks award 300 XP; Gun Store weapons lockers award 375 XP.
- Key names and door labels can differ, e.g. Counting Room Vault opens the casino Counting Room.
- No use counter is shown on keys. Gun Store, Reactor DRC and Supreme Leader cards are confirmed consumed on use.
- Air Base Access Card - Multi Use reportedly survives its first door; exact uses unknown.
21 more
- Key durability is unconfirmed. A leaked, unreleased Keysmith trait mentions keys at max durability.
- Items in Secure Slots survive a failed exfil; keys left in the backpack drop on death.
- Door Breacher Charge: Ultra single-use consumable that opens a locked key door without its key.
- Breacher reportedly cannot open weapon lockers, keycard doors or the Supreme Leader's Bunker.
- Breacher sources: DMZ level 62 reward, 3D Printer recipe (1 Experimental Compounds, 5 Stock Rod, 3 Volatile Explosives), rotating Vendor stock.
- An early glitch let breachers be reused from a Secure Slot; reportedly patched.
- Key Cash is a confirmed Scout trait paying cash for each locked space opened with a key; amounts unpublished.
- A Lockpicking trait appears only in leaks and is unconfirmed.
- Lieutenants can drop a key to their own loot room, which usually holds a Lieutenant crate.
- Level kits grant keys: Explosives Kit L16 and Trap Kit L42 (Gun Store), Recon Kit L19 (Police), Recon Kit L46 (Black Market).
- Story missions reward keys and can be replayed to earn them again.
- Critical Extraction gives Mirae Electrical Room; Silent Ledger gives Counting Room Vault; Shopping Hacks gives Coin Mining Den.
- Iron Citadel gives the Supreme Leader card; Grid Assault gives Roze's Highrise Armory; Fallen Ember gives Reactor DRC Locker.
- Three DRC Elite Weapons Lockers exist (Air Base, Reactor, Shopping); each needs its own Ultra key.
- Each gun store has three basement weapons lockers; one Gun Store key opens one locker.
- Hajin has five police stations, each with a basement armory; one key per station is disputed.
- Keypads, bank power panels, camera-controlled gates and K9 core terminals do not take keys.
- Reactor rooms need radiation protection; fire stations stock radiation gear.
- A door locked from the inside hints at another entrance to that room.
- Keys turn up in jackets, duffels, lockers, safes, Lieutenant bodies and other players.
- Key databases disagree on totals (43 to 53) because several entries are unconfirmed or duplicated.
