Locked Gate Event Guide: Security Code Locations

A rare new event has arrived to ARC Raiders called the Locked Gate. You can find it on The Blue Gate map, and it appears every so often as an available map modifier. When you get into this event, there's a specific goal you and the other raiders are trying to complete, involving four keys and opening those locked doors. This page shares with you everything you need to know about the Locked Gate Event and how to find the security code locations.

Locked Gate Event

The Locked Gate Event appears like the Hidden Bunker, Cold Snap, or the Electromagnetic Storm. You have to choose to start a game with it. When you begin, the primary goal of this event is to track down the four security codes, and use them to unlock the doors.

There are a handful of modifiers that occur with this event.

  • Fewer active Return Points
  • No active Raider Hatches
  • Collect Security Codes

As you don't have too many Return Points to use, understanding the map and knowing where to go will be key to completing this mode. You may also want to work with a team to increase your chances of success, as other players will be hunting down the key cards.

The key cards have a chance to appear at specific locations throughout the map, but you need to find the central security room to know where to go first.

How to Find All Security Code Locations

When you start the Locked Gate match, you'll begin in a random part of the map as you usually do. However, you want to reach the Gate Control Room. You can find it in the Warehouse Complex, close to the center of the map, in The Blue Gate.

When you arrive at this location, expect to find several ARC units guarding it. You should see more of them throughout the map, guarding many of the points of interest. At the Gate Control Room, there are several computers on either side of the room.

These computers require you to track down 4 Security Codes at different locations. You can approach any of the computers to see which locations they are, and if it still requires a key. If one of these computers does not have a prompt when you approach it, it's safe to assume another player has already completed that key terminal.

These are the four locations where you can find Security Codes in ARC Raiders. These were the locations for our game. We're not sure if they change or if they remain the same, given the limited number of times we've had the chance to complete this event.

  • Ancient Fort
  • Pilgrim's Peak
  • Raider's Refuge
  • Reinforced Reception

Each location has a key you need to bring back to the Gate Control Room and insert it into the terminal. These keys can appear in any searchable container, which means it can take some time to turn over each container before you find it. Again, more ARC units are roaming these locations, which can make it difficult to travel throughout the map.

After all four keys have gone into the terminals, the outer gates open! A notification goes out to all players on the map sharing this information, and then the gates to the Checkpoint open up. The checkpoint leads to the underground area. Typically, it's open if you're on a standard Blue Gate match.

Now, you can freely explore this underground area, where there's a fair amount more loot hidden throughout it. The rooms within the Traffic Tunnels have a chance to drop rarer blueprints, such as the Bobcat. There's still a random chance, so there's no guarentee you'll get anything incredibly rare, and you have to get it before the other players in your match loot them!
