Keys are a durability purchase,
not a loot purchase

Three facts that change how you buy keys

Before any tier list, three mechanical facts do most of the work. None of them are visible on the key’s tooltip, and all three are the reason a key that looks expensive can be cheap and one that looks cheap can be a trap.

One: keys never drop on death

A key lives in your keychain, and dying does not take it off you. This removes the usual risk calculation entirely — you are not risking the key on a raid, you are only risking the time it takes to walk to the door. A key you own is a permanent option, so the question is never “can I afford to bring it” but “is this door worth the detour this raid”.

Two: durability is the price, not the sticker

Opening a door consumes durability units, and different rooms cost different amounts. A door that eats two units per open on a 30-durability key is fifteen visits, not thirty. Divide the purchase price by the number of openings rather than the durability number and the ranking of the market changes: a mid-priced key that charges one unit per open can be cheaper per visit than a bargain key that charges three.

Three: the loot is rolled, so the grade is a floor

Containers inside a locked room carry a chance at high-value items, and the chance is not the same as a guarantee. The tier grades on this site rank the container classes present in a room against each other — a premium weapon case outranks a jacket every time — but they are relative, not a price. A room with two safes can pay nothing; a room with one safe and a rare table spawn can pay for the key in a single visit. Plan on averages, not on the highlight clip.

The twelve rooms that pay for themselves

Twelve of the thirteen documented keys carry both a container list and a score. Ranked by the container weight behind the door, these are the ones where a single good roll can cover the purchase and the repeat visits are pure profit.

Two patterns stand out. First, the highest-graded rooms are almost all built around an electronic safe or a premium weapon case — the container type matters more than the count of containers, because the container class sets the ceiling on the roll. A room with four jackets is not a loot room, it is a jacket room. Second, the graded rooms concentrate on Farm and Valley, which is where the key economy actually lives; Armory’s five key rooms are almost all inside a single structure and are priced around contest rather than around yield.

What is inside the best room, concretely

Take the top-graded Farm key as the worked example. Behind it: an electronic safe, a standard safe, a premium weapon container, a coat, and a rare table spawn — five separate rolls, two of which are electronics-class containers and one of which is the best weapon container in the game. That is what a premium key buys you: not one good container, but a stack of independent rolls where the ceiling is high and the floor is still a weapon case.

Contrast that with a mid-graded Valley bedroom key: an electronic safe, a premium weapon case, and a coat. Fewer containers, one fewer independent roll, but it costs less and it opens somewhere safer. For a solo player grinding money, the second key is often the better purchase, because the first one’s room sits in a contested compound where arriving late is normal and leaving alive is the hard part.

The 30 keys with no published container list

Roughly seven in ten of the key set has a sector and a durability value but no container manifest in the published data. That is not the same as being worthless — it means the source has not enumerated the room, so this site will not invent contents for it. Here is the full remainder, so you can at least see what exists and on which sector it opens.

Treat this table as a shopping list to verify rather than a ranking. If you loot one of these rooms and the contents are worth publishing, that is exactly the kind of correction the sources and method page exists to collect.

Where the keys actually are: sector by sector

Key density is not evenly distributed, and neither is the risk of using one.

Farm: the money map

Farm carries the deepest key economy, and it is the only sector where the cheapest key in the game is also a sensible first purchase: the stables warehouse key opens a house at the stables with a real container list behind it, for a price that a first raid can cover. Two warnings. The house has one exit, so a key room with a single door is a coffin if somebody hears you open it. And the stables and motel clusters are where every other keyed player is heading in the first three minutes, so the value of arriving second is higher than the value of arriving first.

Farm also holds the best-graded room on the site and a handful of mid-grade rooms around Motel. If you are going to own one key per sector, own a Farm key.

Valley: eight rooms, better spread

Valley has the widest spread of key rooms, with markers distributed from the beach villa across the village and the radar station to the factory. The practical advantage over Farm is that the rooms are not all in one compound: the beach villa bedroom and the factory dressing room are far enough apart that two players with keys are not competing for the same door. The disadvantage is that Valley’s extracts are more conditional — several require an item or a payment — so a heavy key run needs a plan for leaving that does not involve a toll you did not bring.

Armory: five rooms inside one building

Armory’s five key rooms are the Private Lounge, Second Floor Lounge, Equipment Storage, Command Room and Weapon Storage, and every one of them is inside the Armory structure. The loot is genuinely good — safes, weapon cases, a fully-modded firearm behind one of the keycards — but the map is small, all eight spawns are on the periphery, and the boss patrols the central machinery. A key run here is not a looting trip, it is a fight for a building. Take keys to Armory only when the rest of your kit is ready to hold a floor.

Northridge and TV Station: keys exist, contents unpublished

Several keys open doors on Northridge, and the planning room key opens a documented room on TV Station with a suitcase, a military computer, two military supply crates, a safe and a tactical accessory case — a genuinely good room, in the hot zone, on the first floor of the most contested building on the map. The difficulty is not the loot, it is surviving the walk. Bots on TV Station open doors, so a locked room is not a safe room.

The container carry problem

There is a fourth fact that gets ignored: a key room can be worth more than your bag can hold. Premium weapon cases and electronic safes produce items with size, and a large find that does not fit is a find you leave on the floor. If you are running keyed raids seriously, the case in your inventory is part of the kit, and a titanium case converts a good roll into a good raid in a way that no additional key does.

The same logic argues against over-buying keys early. Two keys you can carry the loot out of beat five keys where the third find forces a choice about what to abandon.

The buying order

1. One cheap Farm key with a real container list. Learn the route, learn the door, learn the exit.
2. One high-grade Farm or Valley key. Buy the room with the electronic safe and the weapon container, not the room with the most containers.
3. A case before a third key. Capacity converts loot into money; a key only creates the opportunity.
4. Armory keycards last. They are PvP equipment, not income equipment.
