Collect Doomsday Control Keys from high security IO locations is one of the Resistance challenges in Fortnite Chapter 3 Season 2.
You will first need to patch The Imagined into a loudspeaker before unlocking this Week 10 challenge. Luckily, you don't need to find the Doomsday Control Keys in the same match, so don't worry if you get eliminated before collecting both.
Completing this challenge will reward you with 23k XP, which will help you unlock skins from the new battle pass.
Note this particular challenge is no longer able to be completed. What's new? Chapter 4 Season 2 has arrived! New additions include the Grind Rails and Kinetic Blades, along with the new Battle Pass, character collection and Eren Jaeger skin. It's a good idea to know how to get XP fast in Fortnite.
Where to find Doomsday Control Keys in Fortnite
Before you start searching for Doomsday Control Keys, you must first establish a Device Uplink near The Collider or The Fortress.
It doesn't matter which location you establish the Device Uplink at, as both The Collider and The Fortress areas contain the Doomsday Control Keys you must find next.
Once you have established the Device Uplink, it's time to collect Doomsday Control Keys.
Fortnite Chapter 4 Season 4 is here! To help you get started with this heist themed season, we have guides on how to alert a Securitry Camera, secure data from Forecast Towers and destroy weakened walls or security gates. There's also a new Victory Umbrella! Meanwhile, learn what the best weapons are, the current Augments, how to get XP fast, use the best PC settings and earn a Victory Crown.
The Fortress Doomsday Control Key location
The Fortress Doomsday Control Key is the easiest of the two keys to locate. Pin the general location noted on the map, then head to the nearby reboot van at The Fortress.
You will find The Fortress Doomsday Control Key between the chairs and the campfire by the reboot van.
The Collider Doomsday Control Key location
The Collider Doomsday Control Key is harder to collect due to Huntmaster Saber opening fire when you get near the key's location.
We don't recommend fighting Huntmaster Saber, as he has a lot of health, shields, and a powerful thermal weapon. Instead, run under the bridge down the hill from The Collider's reboot van to quickly find the last Collider Doomsday Control Key beside a boulder.
