The J-Lab Access Cards are a set of colored keycards used to unlock restricted rooms inside J-Labs in Escape from Duckov. Each color grants access to a different area, often containing high-value loot, quest items, or rare enemies.
This guide covers every known location, spawn method, and drop source for all six J-Lab keycards — helping you build a full access set efficiently.
Each card color (Blue, Purple, Black, Red, Yellow, and Green) has unique acquisition conditions. Some drop from bosses or merchants in Farm Town, while others can only be found inside J-Labs itself.
Below, you’ll find detailed information for each card — including drop rates, exact room locations, and recommended farming tips.
Blue Keycard
Farm Town – Mine Manager
- Drop Source: Has roughly a 10% chance to drop from the Mine Manager, located in Farm Town.
- Use: Grants access to the first locked rooms in J-Labs (essential for early progression).
- Tip: The Mine Manager respawns fairly quickly, so you can repeat this fight multiple times if unlucky.
Location: Found near the Mine Office area within Farm Town’s lower section.
Purple Keycard
Sawmill Area
- Spawn: Found in a small shed within the Sawmill, typically near the lumber stacks.
- Use: Opens secondary storage and item rooms deeper in J-Labs.
- Tip: Check the corner tables and shelves — the purple card sometimes spawns slightly off the main path.
Location: Sawmill outskirts (Farm Town North).
Black Keycard
Farm Town – Mysterious Merchant
- Purchase: Sold by the Mysterious Merchant for 200,000 cash.
- Use: Unlocks restricted experimental areas in J-Labs where higher-tier loot spawns.
- Tip: The Mysterious Merchant’s inventory can refresh — check back often or after major events.
Location: Inside the Merchant’s tent, west of Farm Town’s market district.
Red Keycard
The Red Keycard has two possible acquisition paths — one from a boss in Farm Town and another inside J-Labs.
Farm Town Source
- Drop Source: Drops with around 10% probability from the boss marked as “???”, located near the red ? marker on the Farm Town map.
- Tip: Bring strong gear — this boss hits hard and summons reinforcements.
J-Labs Source
- Spawn: Found on a desk inside the Blue Keycard room within J-Labs (requires Blue Keycard access).
- Tip: Once you have the Blue Card, check all desks carefully — it’s easy to miss under lighting glare.
Location: Blue Room office, J-Labs.
Yellow Keycard
Like the Red Keycard, the Yellow Card also has two spawn zones.
Farm Town Source
- Drop Source: Around 5% chance to drop from the Mysterious Merchant (rare event or post-purchase interaction).
- Tip: Interact with the merchant multiple times; it can drop after a special dialogue trigger.
J-Labs Sources
- Found on a desk in the B1 medical wing, near the Screening Room.
- Another possible spawn is on a desk in the leftmost B1 room, same floor.
Location: J-Labs, Basement Level 1 (Medical Sector).
Green Keycard
J-Labs Exclusive
- Spawn #1: Found in B2 Lounge Room, sitting on a chair near the central console.
- Spawn #2: Found in the B2 Prison Wing, just before entering the electrified basement section.
- Use: Grants access to the lowest J-Labs areas containing advanced loot and experimental weapon data.
- Tip: Always bring a light source; these rooms are notoriously dark, making the green card blend into the environment.
Location: J-Labs Basement Level 2 (Lounge & Prison Wing).
Collecting all six J-Lab keycards opens nearly every hidden room and high-tier loot zone in Escape from Duckov.
Start by farming Blue and Purple cards in Farm Town, buy the Black card once you’re rich enough, and push deeper into J-Labs for Red, Yellow, and Green keys.
