What ARC Raiders keys open
Keys open locked rooms and doors across every map, from the Dam's Control Tower to the Riven Tides hotel rooms and the Stella Montis Archives. The Raider Hatch Key opens a Raider Hatch, a way out of a raid without reaching an extraction point. Each key opens its own door, so pick the map and room you're after.
Single use, so plan the run
A key is used up when it opens its door. It's also lost if you go down while carrying it, unless it's in your safe pocket. Buy the key for the run you have in mind.
Why buy keys instead of finding them
Keys turn up at random, and the rarer rooms can take many raids before the right key drops. Buying the exact key you need lets you plan a run around that room instead of waiting on luck.
