How to get Lockbox Keys
Lockbox locations

Your main goal in Marathon is to scrounge as much loot as you can in each run and do everything you can to avoid dying and losing it all. Activities are the best way to do this, and most just require you to show up and take part. But lockbox caches? You'll need Lockbox Keys.

These special keys require a bit of effort to get, but it's worth the hassle for all the loot you can nab.

You can get Lockbox Keys by either:

Finding them inside containers and loosely placed on top of objects
By purchasing them from the Armory once you have the Locksmith CyberAcme upgrade

Lockbox Keys are pretty rare to find out in the world, especially when you need them, but they can spawn in containers or as a loose item on top of boxes, tables, and so on. They're also small, so they're easy to overlook.

The much more direct method of getting Lockbox Keys is to buy them, but you'll need to get CyAc's Locksmith perk at rank 4 for 2,500 credits first. You can upgrade this skill later on to get higher-quality keys for different areas. With this upgrade, you can then go to the Armory before a match to purchase one from CyberAcme. The materials you'll need to buy the key change every so often, but can include things like Sparkleaf, Reclaimed Biostripping, Dermachem Packs, Plasma Filaments, and credits.

You can use Lockbox Keys to open caches, which are rooms filled with various locked chests, marked by red flares on the roof, so long as you have a key in your inventory. With no safe pocket to store a key in, you'll want to avoid dying and losing your key too.

Each locked container in the cache rooms requires a key, and it's very unlikely you'll have ten odd keys to be able to open all of them, so it's a bit of a gamble in terms of what loot you'll get. Generally, lockboxes contain valuables, salvage (crafting materials), credits, Cores, and consumables.

Spawns aren't guaranteed each match either, but I've found lockboxes in the following locations:

Perimeter

The blue building at the centre of Station
The east side large building in the east side of North Relay
The destroyed section of the main building on the western edge of South Relay

Dire Marsh

In the central building at Quarantine

Rory has made the fatal error of playing way too many live service games at once, and somehow still finding time for everything in between. Sure, he’s an expert at Destiny 2, Call of Duty, and more, but at what cost? He’s even sunk 1,000 hours into The Elder Scrolls Online over the years. At least he put all those hours spent grinding challenges to good use over the years as a freelancer and guides editor. In his spare time, he’s also an avid video creator, often breaking down the environmental design of his favourite games. If you can’t track him down, he’s probably lost in a cave with a bunch of dwarves shouting “rock and stone” to no end.
