How to Find All 4 Security Codes and Open the Arc Raiders Locked Gate

What Is the Locked Gate Event on the Blue Gate Map?

The Locked Gate event represents one of the most complex map-wide modifiers in Arc Raiders. Unlike standard raids where your primary goal is to scavenge and extract, this event transforms the entire session into a coordinated puzzle-hunt. It is widely considered a top-tier challenge for both solo players and squads due to the increased environmental hazards and the inevitable PvP "meat grinder" that occurs once the gate is breached.

According to the official community wiki , the event operates on a 12-hour cycle, appearing for a 1-hour availability window. During this time, the map undergoes significant changes. Most notably, Raider Hatches are disabled , and the number of active Return Points is strictly limited. This creates a high-pressure environment where extraction is not guaranteed, even if you manage to secure the loot.

The physical gate itself is located at the Checkpoint POI , but you cannot simply walk up and open it. The event requires the manual collection of four unique Security Code items. These are physical objects that take up inventory space, making inventory management a critical part of the run. Many veteran players use the Metaforge app to track the exact start times of these events to ensure they load into the lobby the moment the window opens.

How to Find All 4 Security Codes for the Gate Control Room

To unlock the underground bunker, you must visit four distinct locations across the map. Each location houses a single Security Code. These codes are not randomized; they appear in the same POIs every match, though their specific spawn point within that POI may shift slightly between containers or desks.

Finding the Code at Raider's Refuge

Raider's Refuge serves as the "entry-level" challenge for the code hunt. Because it is centrally located and lacks the heavy AI presence of Pilgrim's Peak, it is almost always the first stop for squads. To find the code here, focus your search on the multi-story building with the satellite dish. The code item has a distinct yellow glow in the inventory, making it easy to distinguish from common scrap.

Surviving the Rocketeers at Pilgrim's Peak

Pilgrim's Peak is widely regarded as one of the most difficult POIs during this event. The two Rocketeer units have a wide field of view and can suppress an entire squad from the hilltop. Tactical experts suggest approaching from the eastern cliffside to gain a height advantage. Once the Rocketeers are neutralized, the Security Code can be found in the communications room at the base of the tower. According to IGN's tactical guide , clearing this area early is vital because it provides a vantage point over the rest of the map.

Locating the Code at Reinforced Reception

Reinforced Reception is a maze of corridors and shipping containers. The code here is notoriously difficult to spot because it often spawns inside "Searchable" containers rather than sitting out in the open. Check every filing cabinet and desk in the security office. Because this area is so enclosed, it is a favorite spot for "rats" (players who hide and wait for others to do the work). Always clear the corners before interacting with a container.

Navigating the Buried Mines at Ancient Fort

Ancient Fort requires a slow, methodical approach. The developers have placed several Buried Mines in the tall grass surrounding the code's spawn point. If you hear a high-pitched beep, stop moving immediately and look down. You can disarm these mines for extra parts or simply walk around them. The code is typically located in the basement of the ruined keep, often sitting on a stone pedestal that looks like a piece of environmental set dressing.

How to Use the Gate Control Room in the Warehouse Complex

Once you have collected the codes—or at least some of them—you must head to the Warehouse Complex . This is the central hub for the event. Inside the main warehouse, you will find a control room with four computer terminals. Each terminal corresponds to one of the POIs you just visited.

Inserting a code is a manual process that takes approximately five seconds per terminal. During this time, you are completely vulnerable. If you are playing in a squad, one person should handle the consoles while the others provide 360-degree security. As each code is accepted, a light on the main console will turn from red to green. When all four are active, a map-wide siren will sound, and a notification will appear for every player in the session: "THE GATE IS OPENING."

This notification is a double-edged sword. While it signals your success, it also acts as a dinner bell for every other Raider on the map. Most players who haven't been hunting keys will now converge on the Checkpoint POI to steal the loot from the players who did the hard work. This phase of the match is often described as a "PvP Meat Grinder" by the community on Steam forums .

Is the Locked Gate Loot Worth the PvP Risk?

The rewards for opening the gate are significant, but they are not guaranteed. The primary attraction is the "Red Loot Room," an underground bunker filled with high-tier containers. Unlike standard crates, these have a significantly higher chance of dropping rare blueprints and weapon components.

The Bobcat Blueprint

This is the "holy grail" of the event. The Bobcat is a top-rated weapon that performs exceptionally well in both PvE and PvP. It typically spawns in the dressers or large military gun cases inside the bunker.

Mk3 Survivor Augments

These are often found in the trash cans and small containers within the tunnel system. They provide substantial boosts to health regeneration and stamina, making them a staple for end-game builds.

Tempest III & Aventor Cases

High-tier weapon cases are scattered throughout the bunker. While the contents are randomized, they consistently rank among the strongest gear drops available on the Blue Gate map.

There is a common community belief that the entire map receives a loot buff while the gate is open. While this hasn't been officially confirmed by the developers, many players report finding better items in standard POIs during the event window. Whether this is a mechanical reality or simply a result of players being more observant during high-stakes runs is a matter of debate among the "Satisfied Raiders" on Reddit .

Advanced Strategies to Beat the "Key Hoarding" Meta

As the game has matured, a "Key Hoarding" meta has emerged that can make the event difficult for casual players. Because Security Codes are small items, they can be placed in your Safe Pocket . This means that even if you die, you keep the code in your permanent inventory.

This leads to the "Minute One" opening . A squad using this tactic can sprint directly to the Warehouse Complex the moment they spawn and open the gate before anyone else has even reached the first POI. If you arrive at a POI and find the code missing, it is a strong sign that you are in a "Bricked Lobby" where players have already extracted with the keys or are currently heading to the consoles.

If you find yourself cornered by a superior squad while carrying a key, use the Surrender Mechanic . By surrendering, you ensure that your Safe Pocket items remain protected, allowing you to try again in the next session without losing your progress. This persistence strategy is a significant advancement in how players approach map-wide events.

Why You Should Try the Late-Match Scavenger Strategy

For solo players or those with lower-tier gear, the best way to experience the Locked Gate is often to wait. The standard raid timer is 40 minutes. Most high-level squads will open the gate, loot the Red Room, and extract within the first 20 minutes to avoid the closing extraction window.

By adopting a Late-Match Scavenger tactic, you enter the tunnels in the final 10-15 minutes of the match. While the "best" loot in the main cases may be gone, these squads often miss "Breaches"—hidden walls that require explosives to open—and overlook smaller containers like guard booth computers or trash cans. These overlooked spots can still yield Mk3 Augments and rare attachments. The risk, of course, is that you will have very little time to reach a Return Point, especially since Raider Hatches are disabled during the event.

How to Survive PvP Rats and Campers During the Event

The Warehouse Complex and the Checkpoint Gate are notorious for "rats"—players who sit in dark corners with silenced weapons waiting for someone else to open the door. To counter this, always carry Jolt Mines . Placing a mine at the entrance of the control room or the tunnel provides an early warning system. If the mine triggers, you know exactly where the threat is coming from.

Another community-driven tactic is the use of Proximity Chat code words . In recent months, the word "Cheesecake" has become a semi-official signal for "I am friendly and just want to loot." While not every player will honor this, it can occasionally lead to temporary alliances between solo players who want to take down a larger squad or share the burden of carrying the codes. According to The Gaming Merchant , these social interactions are what make the Locked Gate event one of the most memorable experiences in the game.
