Extracting valuable gear in a multiverse full of anomalies requires more than just good aim; it demands map knowledge and the right access tools. Knowing the best active matter key locations can completely transform your raid economy, turning an average run into a high-tier haul of epic weapons and rare equipment. Whether you are hunting for high-value contraband or trying to figure out how to unlock heavily guarded rooms across Dalniy Island, mastering key runs is the ultimate path to survival.
Quick answer
Keys in Active Matter are single-use items that unlock high-tier loot rooms, military crates, and armories across various maps. You can craft them using the Refiner with a Delta Monolith unlock and fuses, or loot them directly from jackets, lockers, and sheds in hotspots like Factory, Dam, and the Military Base.
Understanding Key Crafting and Where to Find Cassettes
Before heading straight into specific active matter key locations, you need to understand how keys enter your inventory. According to advanced player reports and early access gameplay insights, players cannot craft keys right away at the start of the game. You first need to progress until you hit the Delta Monolith level to unlock the key crafting blueprint.
Once unlocked, you head to the refiner. The crafting process requires standard fuses alongside a specific crafting item: the black milk cassette. Because these cassette tapes are quite rare, many seasoned operatives rely heavily on scavenging them or finding pre-made keys directly in-raid.

Community reports indicate that jacket pockets and industrial lockers offer the highest spawn rates for both cassette tapes and direct key drops. Whenever you spot a row of lockers in a garage or vehicle hangar, make it a priority to search them.

Factory Hangar Runs
Factory is a compact map that guarantees fast action. Experienced players frequently target the buildings adjacent to the central mission scanner zones. The keys for Hangar 17 and Hangar 18 spawn regularly in these structures. However, because the map is small, expect heavy resistance and potential extraction campers. Always secure your keys inside a safe container before pushing these hangars.
Military Base Armories and Hangars
For players seeking heavy firepower, the Military Base is unmatched. Barrack 1 and Barrack 2 house Armory #1 and Armory #2 keys, which unlock rooms completely stacked with assault rifles and ammunition crates. Navigating this area safely requires bringing plenty of fragmentation grenades to deal with the stone men scattered across the terrain.
Grenade Management
Always pack at least eight grenades when running the Military Base. You will need them to clear out environmental anomalies and hostile entities, but make sure to save a couple for your final extraction path.
Unlocking Secret Loot Rooms and Actuator Boards
Beyond standard door keys, some of the most rewarding zones require completing specific questlines to acquire specialized access items like lock actuator boards. According to community walkthroughs, progressing through the Dam investigation questline unlocks the blueprint recipe for lock actuator boards at your workshop.
Volume vs. Value Trap
When looting secret rooms, pay close attention to item volume versus credit value. Do not fill your backpack with heavy, low-value items just because they look unique. Prioritize high-value items like undamaged chains or rare albums that offer a high credit-to-space ratio.
Once you craft your lock actuator boards using an accumulator battery, you can transport them to specific locations on maps like Dam and Dogorsk. For instance, utilizing the actuator board on Dogorsk grants access to rooms containing high-tier weaponry such as adjusted PKMs and balanced AK-74Ms with unique stat bonuses that cannot be crafted at standard benches.

Strategies for Safe Key Extraction and Economy Management
Running key rooms successfully requires discipline. Because keys are currently single-use items, wasting them on poorly planned raids can quickly drain your resources. Follow these tactical steps to maximize every key run:
Stack and Bulk Run: If you accumulate multiple keys for a specific map—such as the attic keys on Shegolskoe—store them safely until you have a full set, then knock them out in a single efficient session.
Bring Pack Animals: Utilize high-capacity storage solutions or deployable support items like a Robot Dog to expand your carry volume significantly.
Monitor Active Matter Yields: Engaging with anomalous zones and entities like devourers during port or dam runs can yield substantial active matter, which converts directly into high-value credits at a rate of 100 active matter for 10,000 credits.
Plan Your Extract: Always verify active time extracts or teleporters near your target location before unlocking a room, ensuring you have a clean exit route when your inventory is maxed out.
By combining careful map routing with efficient inventory management, you can leverage these active matter key locations to gear up consistently and outpace rival operatives in the multiverse.

What should I look for when looting high-tier active matter key locations?
Focus on high-tier weapons with built-in stat bonuses, military medical crates, and high-value, low-volume trade items. Always balance item weight/volume against its credit payout to ensure your extraction is as profitable as possible.
