Locked Gate Arc Raiders event reveals exactly where all 4 security codes hide, but collecting them before enemies arrive is nearly impossible

Arc Raiders Locked Gate event challenges you to collect 4 security codes hidden across The Blue Gate map. This rare event returned after the Cold Snap update, rewarding players with premium loot including rare blueprints. We’ll show you exactly where to find all security codes and unlock access to high-value treasure.

Locked Gate Event Overview and Setup

The Locked Gate event is an exclusive challenge appearing occasionally on The Blue Gate map. You choose to activate it before starting your raid, similar to other special modifiers like Hidden Bunker or Cold Snap.

This event introduces unique map conditions. Fewer Return Points become available, no Raider Hatches appear, and hostile ARC units guard all security code locations. The primary objective involves collecting security codes before competitors extract them.

Finding the Gate Control Room Location

Your first step requires reaching the Gate Control Room, the central hub where all security codes lock into terminals. The control room sits in the Warehouse Complex, positioned near the exact center of The Blue Gate map.

When you arrive, expect heavy ARC unit presence defending the facility. The room features multiple computer terminals on both sides. Approach any terminal to discover which locations still need codes—other players may have already completed certain terminals.

If a terminal shows no interaction prompt, another raider has already submitted that security code. This makes teamwork valuable for splitting objectives efficiently.

All 4 Security Code Locations on Blue Gate

Location Name	Regional Zone	ARC Threat Level
Ancient Fort	Eastern sector	High
Pilgrim’s Peak	Western sector	High
Raider’s Refuge	Southern sector	Very High
Reinforced Reception	Northern sector	High

Each location spawns a security code you must retrieve during the Locked Gate event. Security codes appear inside any searchable container at these locations, meaning you’ll search crates, boxes, and loot containers throughout each area.

Important: codes spawn only during Locked Gate events, so you can’t farm them in regular raids or save progress across multiple missions. Each location contains multiple containers, so check everything thoroughly before moving zones.

Collecting Codes and Managing ARC Opposition

Expect intense ARC unit patrols at every security code location. These military units guard key points of interest across the map, making collection treacherous.

Strategy matters here—use cover effectively when moving between containers, time your looting carefully, and consider using suppressing fire if playing with teammates. Landmines spawn heavily around security code locations, so watch for pressure-activated explosives near stairways and chokepoints.

Once you collect all 4 codes, navigate back to Warehouse Complex and return to the Gate Control Room. Input each code into its corresponding terminal. The system displays clearly which terminals still need codes.

What Happens When All Codes Are Submitted?

The Locked Gate opens immediately after inputting all 4 security codes into their terminals. A notification broadcasts to every player on the map, alerting everyone that the gate has breached.

Access now unlocks to the underground tunnel system beneath The Blue Gate, normally sealed during standard matches. This underground area contains exceptional loot including rare weapons, premium blueprints like the Bobcat, and high-value key cards.

However, you face intense competition—other players immediately rush toward the unlocked gate seeking rare drops. Extraction becomes critical; secure your valuable loot and reach a return point before enemies eliminate you.

Underground Treasure and Loot Prospects

The Traffic Tunnels within the underground area hold dramatically higher rarity loot compared to surface maps. Expect to find premium weapons and specialized blueprints rarely discovered elsewhere. The Bobcat Blueprint appears more frequently in these tunnels than in regular Blue Gate raids.

Competition intensifies significantly since extracting with legendary loot puts targets on your back. Stack extraction points efficiently and watch for ambushes.

“The Locked Gate was in the game previously but was quickly removed, likely due to a bug that prevented players from earning the loot they were supposed to find.”

Pro Tips for Locked Gate Event Success?

Teamwork dramatically increases completion odds—assign teammates to specific locations while communications maintain real-time updates on threats and positions. Squad play protects code carriers effectively.

Scout locations before committing fully; watch for heavy ARC concentrations and identify optimal container-checking routes minimizing exposure. Extract planning matters as much as collection; location your nearest return point before grabbing premium loot.

Use the Warehouse Complex’s central position strategically by establishing it as a temporary safe zone for code consolidation before final terminal submissions. Split responsibilities efficiently instead of all players pursuing identical locations.
