In ARC Raiders' tense extraction gameplay, every key item holds the potential to turn a risky run into a rewarding one-and the Patrol Car Key is no exception. This uncommon, one-time-use key is easy to stumble upon during looting, but many players are left confused about where to use it. Unlike quest-specific keys with clear hints, the Patrol Car Key offers only a vague description: it unlocks the rear door of a patrol car.

The key's true value lies in the mid-tier to high-value loot it grants, from blue weapons and attachments to rare crafting materials. To avoid wasting this valuable item, this guide breaks down exactly where to use the Patrol Car Key, how to reach its target location, and how to claim the loot safely. This will provide you with more ARC Raiders BluePrints, items, and other resources.

The Only Place to Use the Patrol Car Key: Blue Gate's Underground Headhouse

The Patrol Car Key has one exclusive use: unlocking the rear door of armored patrol cars located in the Headhouse area of the Blue Gate region on the Dam Battlegrounds map. This is the only location where the key works-no other patrol cars across ARC Raiders' maps will respond to it.

Blue Gate is a high-traffic zone, known for its mix of hostile ARC enemies and rival raiders. The Headhouse, where the patrol cars reside, is tucked underground, accessible only via stairs and ziplines. This hidden area is designed to feel like a secure transport hub, making it the perfect spot for guarded loot.

Patrol cars in the Headhouse spawn randomly, but they are always found in the underground highway tunnel connected to the Headhouse circle. These vehicles are easy to spot: they're bulky, military-green armored vans with locked rear doors-distinct from the unlocked, looted patrol cars you might find elsewhere.

Step-by-Step: How to Reach the Patrol Cars in Blue Gate

Reaching the Headhouse's underground patrol cars requires navigating Blue Gate's layout carefully. Follow these simple steps to avoid getting lost or ambushed:

Step 1: Locate Blue Gate on Dam Battlegrounds

Blue Gate is positioned near the center of the Dam Battlegrounds map. Look for the large checkpoint structure with guard booths-this is the entrance to Blue Gate. If you're unsure, use your in-game map to mark the Blue Gate region; it's often labeled with a small checkpoint icon.

Step 2: Access the Headhouse Underground

From Blue Gate's main checkpoint, head toward the Headhouse circle near the warehouse complex. You'll find a set of stairs leading downward-take these to reach the underground level. Alternatively, use the zipline nearby to quickly descend, but be cautious: ziplines can expose you to enemy fire.

Once underground, you'll enter a wide highway tunnel filled with abandoned vehicles. This is the patrol car spawn zone-slow down and scan the area for armored vans with locked rear doors. Avoid rushing; the tunnel is often patrolled by ARC enemies like Bastions, which can easily take you down.

Step 3: Use the Patrol Car Key to Unlock the Door

When you find a locked patrol car, approach its rear door. A small interaction prompt will appear-select it to use your Patrol Car Key. The key will be consumed (it's one-time-use), and the rear door will swing open, revealing the loot inside.

If the first patrol car you find is already unlocked, don't panic-patrol cars spawn randomly, so keep searching the tunnel. There are usually 2-3 patrol cars in the area, so you'll likely find a locked one quickly.

What Loot to Expect from the Patrol Car

The patrol car's loot is well worth the trip to Blue Gate. Inside, you'll find a mix of mid-tier and occasionally high-value items that can boost your loadout significantly:

Common rewards include blue-rarity weapons (ideal for mid-game runs), weapon attachments like muzzle breaks, and plenty of ammo to restock your supplies. Some players have also reported finding rare crafting materials like Anvil or even the valuable Torrente blueprint inside these cars.

Even after completing the "Armored Transports" quest (which requires using the Patrol Car Key), the patrol cars remain valuable. Their loot respawns in each match, making the key a reliable way to stock up on gear between main quests.

How to Get a Patrol Car Key (If You Don't Have One)

Before you can use the key, you'll need to find one. Luckily, there are several reliable ways to acquire a Patrol Car Key, ranging from looting to quest rewards:

Loot High-Spawn Areas

The key most often spawns in loot containers and enemy drops in specific locations. Focus on Ruby Residence (a residential area on the western side of Dam Battlegrounds), the Research & Administration building near the map's center, and the guard houses at Blue Gate's checkpoint. Check tables, cabinets, and crates in these areas-they have the highest drop rates.

Complete Quests

You can get a guaranteed Patrol Car Key by completing certain quests. The "Armored Transports" quest explicitly requires the key, and it often rewards one upon completion. Additionally, the "A Prime Specimen" quest also grants a Patrol Car Key as a reward.

Recycle or Purchase

As a last resort, you can sometimes find the key for sale from in-game vendors (for around 100 creds) or recycle unused gear to obtain it. However, recycling is not recommended unless you have spare cheap ARCR Items, as most gear is useful in combat.

Critical Tips for Using the Patrol Car Key Safely

Blue Gate and its underground tunnel are hostile zones-follow these tips to avoid losing your key or your loot:

First, store the key in your safe pocket immediately after finding it. This ensures you won't lose it if you're eliminated by enemies or rival raiders. The safe pocket is a lifesaver, especially in high-risk areas like Blue Gate.

Second, clear the area before using the key. The underground tunnel is often patrolled by Bastions and other ARC enemies, and rival raiders frequently converge here to farm loot. Use long-range weapons to take out threats from a distance, and stay alert for movement.

Third, don't overstay. Once you unlock the patrol car and loot its contents, extract quickly. Lingering in the tunnel increases your chances of being ambushed-grab the loot and go.

Common Mistakes to Avoid

Many players waste their Patrol Car Key by making simple mistakes. Here are the most common ones to steer clear of:

Don't use the key on patrol cars above ground-only the underground patrol cars in Blue Gate's Headhouse will unlock. Above-ground patrol cars are either already looted or don't require a key.

Don't forget the key is one-time-use. Once you use it, it's gone-so make sure you're ready to loot the patrol car before using it. Avoid using it early in a run unless you need the gear immediately.

Don't ignore the area's dangers. Blue Gate is a hotspot for PvP and ARC attacks-going alone is risky. Team up with allies to cover each other while you loot the patrol car.

Final Thoughts

The Patrol Car Key is a valuable tool in ARC Raiders, offering easy access to mid-tier loot that can turn the tide of your run. Its only use-unlocking underground patrol cars in Blue Gate's Headhouse-may seem hidden, but with this guide, you'll navigate the area with confidence.

Remember to find the key in high-spawn areas like Ruby Residence or via quests, store it in your safe pocket, and clear the underground tunnel before using it. By following these steps, you'll make the most of every Patrol Car Key and secure the loot you need to dominate Dam Battlegrounds.
