How to Find and Use the Secret Basement Key in PUBG

Learn how to find and use the Secret Basement Key in PUBG, where it goes, and why its high-tier loot can change your match.

If you’ve ever looted your way through Erangel and stumbled across a Secret Basement Key, you already know it’s one of PUBG’s most intriguing finds. This rare key unlocks a hidden underground vault packed with high-tier loot—but only if you know where to use it and when it’s worth the risk.

In this guide, we’ll break down what the Secret Basement Key is, where it goes, and why it can completely change your match, whether you’re dropping hot or playing for late-game rotations.

What Is the Secret Basement Key in PUBG & How To Find It?

The Secret Basement Key is a rare in-game item that unlocks a hidden loot vault, also known as a secret room, on the Erangel map. Heavy metal doors protect these vaults, and they contain high-tier loot you normally only see in supply drops.

How to Find the Secret Basement Key

Finding the key comes down to RNG and map knowledge. It doesn’t spawn in a fixed location and can appear as:

Floor loot in high-traffic buildings
Inside loot rooms and large compounds
Dropped by eliminated players
Occasionally near hot drops like Military Base

Because of its random nature, your best odds to find it come from:

Dropping early in contested areas
Prioritizing aggressive looting routes
Winning early fights against geared enemies

There’s no guarantee the key will appear in every match, which makes it one of PUBG’s most high-risk, high-reward mechanics, especially for players chasing Level 3 equipment, assault rifles, and endgame-ready kits.

Pro tip: If you find the key early, surviving long enough to use it becomes just as important as finding it in the first place.

Where Does the Secret Basement Key Go in PUBG?

The Secret Basement Key unlocks underground vaults on the Erangel map. These vaults are sealed behind heavy metal doors and lead to secret rooms filled with high-tier loot.

How to Identify a Secret Basement Door

Not all locked areas in PUBG are the same. Secret basement entrances are easy to miss if you don’t know the cues:

Heavy metal doors (not wooden doors or crowbar rooms)
Typically found in isolated buildings or restricted areas
No special marker on the map
Interaction prompt only appears when you’re right in front of it

These vaults are different from:

Crowbar rooms
Standard locked doors
Lab rooms or surface-level loot rooms

Known Areas Where Secret Basements Can Appear

While locations can vary, players most often find secret basement vaults in:

Military Base (the most popular and dangerous spot)
Remote compounds away from major flight paths
Large structures with minimal windows or access points

Because these are secret locations, reaching them often requires smart rotations, good connection stability, and awareness of nearby squads waiting to ambush players opening vaults.

Heads up: Opening the door makes noise. Treat every basement like a potential trap, especially in high-traffic zones.

How Do You Use the Secret Basement Key in PUBG?

Using the Secret Basement Key is straightforward, but surviving the process is where things get tricky.

Step-by-Step: Using the Secret Basement Key

Loot the Secret Basement Key from floor loot or an eliminated player
Travel to a known vault location on Erangel
Find the heavy metal door leading to the basement
Interact with the door (no extra prompt or mini-game)
The key is consumed automatically, unlocking the vault
Enter the secret room and loot quickly

Once opened, the vault stays accessible, but the key cannot be reused.

What to Expect When You Open the Vault

Loud audio cue when the door opens
No delay animation, but clear sound tells nearby players
High chance of third-party pushes
Tight interior space with limited escape routes

Inside, you’ll typically find high-tier loot like:

Level 3 helmet or vest
Assault rifles
Adrenaline Syringes
Med Kits
Frag Grenades

When Not to Use the Key

Even if you have it, using the key isn’t always the right call:

Early game with no armor or utility
Poor circle positioning
Multiple squads nearby
Solo runs without audio or overwatch

Play smart here. Treat the Secret Basement like a mini endgame decision, not just a loot stop.

Why Is the Secret Basement Key Important in PUBG Gameplay?

The Secret Basement Key is important because it gives players access to top-tier loot without relying on supply drops or late-game RNG. Used at the right moment, it can completely change your loadout and your odds of winning the match.

What Makes the Secret Basement So Valuable?

Secret basement vaults are designed to reward players willing to take calculated risks. Compared to standard loot rooms, they consistently deliver:

Level 3 equipment (helmets and vests)
Fully kitted assault rifles
High-value healing items like Adrenaline Syringes and Med Kits
Utility items such as Frag Grenades

This makes the key especially powerful for:

Squads trying to gear up quickly
Players rotating into mid-game circles
Teams recovering after a rough drop

Strategic Advantages Over Other Loot Sources

Unlike an aerial supply drop, secret basements:

Don’t reveal your location on the map
Avoid open-field looting
Let you gear up indoors
Can be accessed earlier in the match

However, they still demand:

Strong map knowledge
Good audio awareness
Smart timing and positioning

PUBG Is Won on Sound, Especially Underground

Secret basement vaults are loud, cramped, and dangerous. If you can’t hear footsteps above the metal door or enemies creeping in while you loot, that high-tier gear won’t matter for long.

Stay one step ahead in high-risk moments with a SteelSeries headset, engineered for precise positional audio, clear team comms, and long sessions where every sound cue counts.

Risk vs. Reward

The basement key embodies classic PUBG decision-making:

High reward: near–supply drop quality gear
High risk: tight spaces, loud doors, frequent ambushes

Treat the basement as a tactical objective, not just a loot stop, to get the most value out of it.

Secret Basement Loot vs. Other Loot Sources

Loot Source	Risk Level	Loot Quality	Visibility	Best Use Case
Secret Basement Vault	High	Very High	Low	Gearing up mid-game without open-field exposure
Supply Drops	Very High	Very High	Very High	Late-game power plays
Standard Compounds	Low	Medium	Low	Early-game survival
Crowbar Rooms	Medium	Medium	Low	Supplementing mid-tier kits
Bear Caves / Lab Rooms	Medium	Medium–High	Medium	Niche loot routes

Pro Tips for Using the Secret Basement Key Safely

Opening up a secret basement vault can instantly upgrade your kit, but it also puts a target on your back. Here are some tips to maximize reward while minimizing risk:

1. Scout Before You Open the Door

The heavy metal door makes a distinct sound when it opens. Before using the key:

Check for nearby footsteps
Watch common push angles
Listen for vehicles rotating in

Audio cues matter more than visuals in tight underground spaces.

2. Bring Utility, Not Just Confidence

Secret basements are cramped and easy to trap.

Carry Frag Grenades to clear corners
Use smokes to block entrances
Keep meds ready for close-range fights

A fully stacked loadout doesn’t help if you get ambushed while looting.

3. Time It With the Circle

Using the key at the wrong moment can get you pinched.

Avoid opening vaults when the blue zone is closing
Use the basement during mid-game rotations
Don’t backtrack through hot drops just to use the key

Smart map knowledge beats greed.

4. Squads Should Assign Roles

If you’re running squads:

One player opens and loots
One player overwatches the door
One player covers flanks or stairwells

Coordinated team comms are especially important in secret rooms with limited exits.

5. Know When to Walk Away

Sometimes the smartest play is not using the key at all.

Too many squads nearby
Poor connection stability
Low ammo or healing

The Secret Basement Key is powerful, but it’s not mandatory to win.

Conclusion: Key in Hand, Pressure On

The Secret Basement Key is one of PUBG’s most exciting risk-reward mechanics. If you know where to use it, when to open it, and how to survive the aftermath, it can turn an average match into a fully stacked run at a chicken dinner.

Treat secret basements like a tactical objective, not just a loot stop. With smart rotations, solid map knowledge, and strong audio awareness, you’ll walk out with high-tier gear instead of becoming someone else’s highlight clip.

Find the key, trust your instincts, and remember: the real fight usually starts after the vault opens.

PUBG Secret Basement Key: FAQs

Can you use the Secret Basement Key in PUBG Mobile?

Yes, the Secret Basement Key exists in PUBG Mobile, but mechanics, spawn rates, and vault locations may differ slightly from the PC and console versions of PUBG: BATTLEGROUNDS. Always double-check map availability and patch notes, as secret locations can change between updates.

Can multiple players enter the secret basement?

Yes. Once the heavy metal door is unlocked, the secret room stays open and can be accessed by any player. This makes secret basements a common ambush point, especially in squad-heavy lobbies.

Does every PUBG match have a Secret Basement Key?

No. The key is not guaranteed to spawn in every match. It appears as random loot, meaning some games will have multiple keys in circulation, while others may have none at all.

Is the Secret Basement Key single-use?

Yes. The key is consumed when used and cannot be reused to open additional vaults. Each key only unlocks one basement door.

Is the loot in the secret basement better than supply drops?

The loot is comparable. Secret basements often contain Level 3 helmets, tier-three gear, assault rifles, and high-value healing items like Adrenaline Syringes. The main advantage is looting indoors without the visibility risk of an aerial supply drop.

Can you tell if a building has a secret basement before entering?

No. Secret basement vaults have no map markers and no visual indicators until you’re close enough to interact with the metal door. Spotting them reliably comes down to map knowledge and experience.
