Where to Use the Blue Gate Cellar Key in ARC Raiders

In ARC Raiders, keys are some of the most valuable items you can bring into a raid. They unlock hidden rooms, stashes, and basements scattered throughout the world—each often filled with high-value materials or rare equipment. While many keys specify exactly where they are used, the Blue Gate Cellar Key is an exception. It provides no description, no POI guidance, and no clear indication of the cellar it’s meant to unlock. Fortunately, despite the lack of labeling, it’s one of the more flexible keys in the game.

This guide explains every place you can use the Blue Gate Cellar Key, highlights the easiest cellar to locate, and previews the kind of loot you can expect once you’re inside.

What the Blue Gate Cellar Key Unlocks

The Blue Gate Cellar Key is used specifically on cellar doors found throughout The Blue Gate region. These cellar entrances often look like small wooden or metal hatches set into the ground or attached to the sides of ruined homes.

Unlike one-time-use keys tied to specific POIs, the Blue Gate Cellar Key can open multiple different cellars, making it far more versatile than many players realize. If you prefer checking cellars for crafting items or quick-use gear, this key is worth holding onto.

Where to Use the Blue Gate Cellar Key

The Blue Gate region is dotted with small structures, abandoned homes, and collapsed farms—many of which have their own sealed cellars. Below are the most reliable and easily accessible locations where you can use the key.

1. The Easiest Cellar Location – West of Ruined Homestead

If you only want one guaranteed, convenient spot to use the key, head to the road west of Ruined Homestead. This is widely considered the most accessible location.

How to Get There

Start at Ruined Homestead, a well-known POI in The Blue Gate.

Follow the road heading west, staying close to the tree line.

Look for a small stone wall just off the road.

A locked cellar hatch sits beside the wall—this is your target.

This cellar is easy to miss if you rush past, so keep an eye out for the stone structure and wooden hatch. It’s a quiet area compared to many other Blue Gate locations, making it a low-pressure place to unlock your first cellar without worrying about raider ambushes or ARC patrols.

Inside the Cellar – What You’ll Find

Once inside, expect modest but useful loot. The cellars unlocked with the Blue Gate Cellar Key aren’t known for high-tier drops, but they’re ideal for stocking up on materials that support early- and mid-game crafting.

Typical Loot Includes:

Electrical and mechanical crafting materials

Ammunition

Medical supplies

Quick-use ARC Raiders Items like grenades or stimulants

Occasional mid-tier weapon attachments or gear pieces

Because the loot pool is broad but not extremely rare, these cellars are often worth checking during a Night Raid. Nighttime boosts your chances of finding higher-tier gear, making those blue and purple drops slightly more common.

2. Additional Cellar Locations Across The Blue Gate

The Blue Gate region contains multiple cellars, and the Blue Gate Cellar Key works at all of them. Here are several more spots worth checking if you're farming materials or exploring the area thoroughly.

South of Raider’s Refuge

Another locked cellar can be found just south of Raider’s Refuge, one of the busier areas on the map. Because raiders frequently travel through this zone, proceed carefully—PvP encounters are more likely here.

This cellar tends to spawn slightly better loot than the one near Ruined Homestead, though still not on par with premium POIs like Pilgrim’s Peak.

Near the Olive Grove

North of the Olive Grove area, you’ll find scattered farm structures that often hide cellar entrances. These can be tucked behind small houses or partially buried next to broken walls or debris piles.

While this area is more open and less predictable, the roaming ARC units tend to be lighter than those near Raider’s Refuge, making it a safer mid-map option.

Attached to Abandoned Houses Throughout the Region

One of the advantages of the Blue Gate Cellar Key is flexibility. Many small abandoned houses and homestead ruins across The Blue Gate have their own hatches, and nearly all of them can be opened with this single key.

If you're exploring or gathering resources, keep an eye on:

Fallen chimneys

Houses partially collapsed into the hillside

Barn-like structures

Loosely fenced farming areas

These structures often hide a cellar entrance, especially if they contain crafting materials or electrical equipment inside.

Is the Blue Gate Cellar Key Worth Using?

Absolutely—but with expectations set correctly.

Why It’s Worth It

Opens multiple cellars, not just one

Provides consistent crafting materials

Simple and quick to loot

Great for early-game resource farming

Useful during Night Raids for better drops

Limitations

Does not yield high-end ARCR Items reliably

Cellars can be spread out, requiring some travel

PvP hotspots like Raider’s Refuge pose a risk

Still, if you’re running raids regularly in The Blue Gate, the key is a worthwhile investment of inventory space. The guaranteed material pickups alone make each cellar visit profitable, and you never know when you’ll grab a grenade or extra attachments that can turn a rough fight in your favor.

Final Tips

Use the key during Night Raids for the best loot quality.

Approach cellars near Raider’s Refuge with caution—expect raider encounters.

Always clear the surrounding area before entering cellars to avoid ambushes.

Keep the key in a safe pocket so you don’t lose it during combat deaths.

The Blue Gate Cellar Key is simple but surprisingly useful, especially when you know the most reliable cellar locations. With multiple hatches available across The Blue Gate and steady crafting supplies inside, the key offers consistent value for any player navigating this early-game region.
