Where to Find Lockboxes in Marathon

How to Get Lockbox Keys

No key, no lockbox. You need a Lockbox Key to open every container in these rooms, and it is one key per one box.

Keys can be obtained through multiple systems:

• crafting
• random loot during runs
• faction contracts and rank-up rewards

The unlock that matters is Locksmith at CyberAcme Rank 4. After that, you can craft keys with materials like Deimosite Rods, Altered Wire, plus credits.

Deluxe and Superior keys are a different system. They open dedicated named rooms, and each key type is tied to its own room and loot profile.

If a key drops naturally while you are already routing an active flare, that is high value. Hard-forcing crafting with no clean extract plan is often a material sink, especially after early game.

How to Find Lockboxes

Lockboxes live in fixed loot-room locations on each map, but only one of the possible rooms is usually active each run.

Lockboxes are not really time-sensitive by themselves. But if another team reaches the room first, they can loot them and you'll just have to rotate to the next objective.

The fastest method is simple: check known spawn routes and commit instantly when you spot the red flare.

Inside, expect around 6 to 7 lockboxes in most runs.

Known Spawn Locations

Dire Marsh usually pays better, but it is also hotter. Better loot means nothing if you cannot extract it. If you find cache coordinates there, just run that one because it usually yields better loot.

But Is It Worth Opening Lockboxes?

Lockboxes can contain:

• weapons
• equipment and gear
• upgrade materials
• large stacks of valuables

Valuables often spawn in near-full stacks and auto-convert into credits on extract, so lockboxes are excellent for early-game economy.

Honest take: lockboxes are mostly worth it only at the very start of the game. One clean room can fund several follow-up runs, but value falls off fast later.

Once you are deeper into Outpost progression, crafting those is usually not the best spend anymore. Those materials are often better invested elsewhere.

Even when keys drop naturally in later stages, many players skip them unless they are already passing a live flare route with minimal risk.

When Lockboxes Are Still Worth It Later

• a MIDA contract requires it
• you are closing out an achievement
• you already have 6-7 spare keys

Need Help Getting Gear?

Most players do not actually care about farming lockboxes. They care about gearing and looting: better weapons, materials, credits, and progression.

If your goal is progression speed, we prioritize routes and contracts that outperform random lockbox farming.

With our help you can quickly obtain:

• faction levels
• upgrade materials
• credits and valuables
