The recently launched DMZ mode in Call of Duty: Warzone 2 brings tense, tactical sandbox gameplay to the franchise‘s battle royale. DMZ takes place on the massive new map of Al Mazrah, allowing up to three-player squads to take on objectives, engage AI combatants, and collect valuable contraband loot to extract or keep between sessions.
One of the most useful keys for loot extraction in DMZ is the Quarry Worker‘s Lost Toolbox key, which provides access to rare weapon blueprints and attachments. Read on for an in-depth 2000+ word guide to locating this key within Al Mazrah‘s winding quarry area.
DMZ Explained – High Risk, High Reward Extraction Shooter
For those new to this genre, DMZ is Warzone 2‘s take on "extraction shooter" games like Escape from Tarkov that have surged in popularity recently. The core gameplay loop focuses on:
- Infiltrating the massive map of Al Mazrah
- Completing mission objectives like securing intel or eliminating targets
- Scavenging for weapons, gear, and valuable contraband loot
- Extracting safely from the map with your haul
- Building up your persistent Operator and weapons across sessions
There is no single victory condition – success in DMZ comes from acquiring sought-after weapons, items and intel, leveling up your personal faction, and making it out of excursions alive.
Death results in all equipped weapons, armor and inventory being permanently lost apart from insured items, so caution is advised. Surviving and extracting safely is critical.
Keys unlock restricted high-tier loot areas and are among the most coveted finds. The Quarry Worker‘s Toolbox key offers access to rare blueprints and gear. Let‘s break down how to acquire it.
DMZ Tips For Beginners
Before jumping into acquiring keys, here are some general tips for DMZ newcomers:
- Pack long range weapons like snipers/DMRs to engage at a distance. Avoid unnecessary risks.
- Prioritize cover and use suppressors to avoid detection. Ambush when possible.
- Learn the AI combatant behaviors – some will flank, some call for backup.
- Complete missions early on for extraction intel rewards.
- Have an exfil plan and getaway vehicle – don‘t get cornered late!
- Insure valuable contraband so it‘s retrievable if you die.
- Play in a squad for revives and support – communication is key!
Now let‘s get to securing that lucrative Quarry Worker‘s Toolbox key.
Pinpointing the Toolbox Location
The Quarry Worker‘s Toolbox key location is found within the northern Al Safwa Quarry area of the Al Mazrah desert region.
Specifically, the key sits at the bottom of a water-filled pit at the highest interior point of the quarry. This pit contains a small pool marked by tires and fencing, overlooked by a large suspended crane.
Once located, Operators simply need to drop down into the pool and collect the key from the submerged toolbox visible at the bottom. No puzzle or action required – just swim down and grab it!
Step-by-Step Navigation to the Toolbox
To reach Al Safwa Quarry, first locate the northernmost road exiting Al Mazrah City on the map, past the Marshlands area. Follow this road generally west as it winds deep into the desert regions until you spot the Quarry‘s entrance on the right side.
Alternatively, several extraction points sit along the southern quarry rim allowing quick access, like the Radar Array. This spot gives a great infiltration vantage point too.
Once inside, be alert for roaming AI combatants throughout the complex. I recommend clearing them quietly or avoiding detection completely to minimize attention.
Next, scale one of the surrounding cliffs using the ladders and platforms provided to gain elevation over the central yard area.
From this higher vantage point, carefully scan for the key pool marked by the crane and fence indicators. Once spotted, mark it on your HUD and formulate a safe approach path.
You can either parachute directly to the marked location, or descend back to ground level and trek there more stealthily. I prefer taking out any nearby hostiles first before moving in.
The pool stretches quite deep, so simply look over the edge and walk off to submerge fully. Swim downwards and you‘ll find the Quarry Worker‘s Toolbox ready to snag the key from. Surface and acquire this valuable asset!
Suggested Loadouts
When pursuing keys, I suggest packing the following type of loadout tuned for range and precision:
Primary: DMR or Sniper Rifle with Suppressor
Secondary: SMG for close quarters
Lethal: Proximity Mine to cover flanks
Tactical: Stim for quick health regen
Perks: Cold Blooded, Spotter, Tracker
The long range capability allows quietly picking off AI patrols before they detect you. Stay stealthy and avoid CQC unless necessary.
Opportunities Unlocked
So what lucrative opportunities does the Quarry Worker‘s Toolbox key grant access to? Primarily it unlocks a small bunker in the immediate vicinity of the key‘s location.
Inside this bunker, Operators will find two locked crates requiring the key to pry open. These crates contain:
- Rare weapon blueprints
- Weapon attachments including optics, magazines, suppressors
- Lethal/tactical equipment
- Armor plates and medicine
This high-tier loot can provide a major edge in firefights and survival. Based on crowd-sourced data, the Quarry Toolbox key bunker has:
Having the key in your persistent inventory also means the ability to return and unlock this bunker across multiple DMZ sessions and continue building up your arsenal over time.
While not a guaranteed source of the absolute rarest S-tier weapons, the consistent quality of loot here is far beyond standard floor drops.
Other Notable DMZ Keys
The Quarry Toolbox key is one of over a dozen different keys littered around Al Mazrah for Operators to find, each unlocking exciting secrets. Other keys to watch for include:
- Smuggler‘s Stash Key: Unlocks black market stash full of contraband loot. Located at Palace.
- Hotel Service Elevator Keycard: Accesses service elevator with rare weapon blueprint. Located at Sawah Hotel.
- Golden Dragon Keycard: Opens executive lounge and penthouse floor loot. Located at Golden Dragon.
Extracting Safely with Your Loot
Securing those elite new weapons is only half the battle – a successful DMZ run means getting out alive! Here are my top tips for safely extracting with high value keys and loot:
- Grab keys early in a session to enable extraction along with other contraband. Complete missions too for exfil intel.
- When holding a key, play ultra-cautiously. Use suppressors and avoid unnecessary firefights.
- Have an armored SUV or helicopter stashed nearby for quick, shielded getaways.
- Use decoy vehicles to bait out enemies at the extraction zone.
- Always have a backup extraction site depending on where the zone is hot.
- Insurance is clutch for keys – losing them stings, but you‘ll get it back next time.
Here‘s an example of effectively juggling multiple keys and loot during an intense extraction:
By playing smart, using distractions, and never getting cornered, your chances of surfacing at exfil with hard-earned keys and weapons intact drastically improve.
The Quarry Worker‘s Toolbox key is one of Al Mazrah‘s most valuable assets. Use the strategies outlined in this 2000+ word guide to reliably add this key to your DMZ inventory, unlock superior loadout potential, and emerge from the Warzone quarries victorious.
