Arc Raiders: Blue Gate Keys Guide

In ARC Raiders, the key system plays an important role: keys grant access to hidden rooms, extra areas, and valuable rewards scattered across the map. The Blue Gate region contains many such doors, and each key unlocks a unique location. This guide will help you understand exactly where to use the keys you find, without going into details about how to find them — a screenshot of the location will be attached for each point.

Where to look for keys and how to obtain them

Most of the keys for the Blue Gate region are located on the Dam Battlegrounds map, primarily around Ruby Residence and the Research & Administration Building. These areas serve as the main spawn points, so it’s worth checking every room, crate, table, and locker carefully. The best strategy is to focus on residential and administrative buildings, as the drop rate for keys tends to be higher there. Since loot respawns after completing missions, make a habit of revisiting Ruby Residence from time to time. Additionally, some keys can occasionally drop from Arc enemies, especially those guarding restricted zones.

Blue Gate Communication Tower Key

This key is used in the northeastern part of the Blue Gate region, near Pilgrim’s Peak. It opens a door beneath the communication tower. To reach it, use the cable and descend into the underground chamber under the tower. Behind the metal door is a small room with valuable loot.

Here’s what the door itself looks like:

Blue Gate Cellar Key

This key opens a cellar door in the southern part of the Blue Gate map, near Ruined Homestead and Olive Grove. The entrance to the cellar is located at the base of a hill next to a rock. The location can be easily missed because the door blends into the environment.

Here’s what the door itself looks like:

Blue Gate Confiscation Key

This key opens a restricted area in the Blue Gate region where confiscated materials are stored. Doors that match this key are marked with yellow warning signs and the label “Confiscation Area.” The location is guarded by enemies, so be prepared for combat before attempting to open the door.

Here’s what the door itself looks like:

Blue Gate Village Key

This key grants access to the northwestern part of the Blue Gate region. After use it unlocks a door leading to a separate sector of the village, where you can explore new buildings and collect rare resources. This location is considered one of the most rewarding for farming — be sure to visit if you want to stock up before future raids.

How to Use Keys Effectively in ARC Raiders

Each key in ARC Raiders is designed to unlock only one specific door and disappears from your inventory once used. To make exploration easier, it’s best to mark door locations on your map and return to them in future raids. Always try to use keys before extracting to minimize the risk of losing them if the run fails. Each Blue Gate key grants access to stashes with valuable loot, including rare weapons, blueprints, crafting resources, grenades, ammo, consumables, and rare components like Sensors, Advanced Electronics, and Mechanical Parts. Based on player experience, using keys is always worthwhile—it's uncommon for the game to reward you with anything less than useful or expensive loot, so don’t ignore these opportunities; when you find a key, visit the location when ready and claim your rewards.

Blue Gate keys open access to additional zones that make ARC Raiders far more interesting and profitable. Use them wisely, thoroughly scan the map, and check the attached screenshots of locations — each of these doors holds something valuable for your progress.
