Are you struggling to locate sufficient Vault Keys during your Blue Prince adventures? Much like other rare artifacts within the game, these crucial items spawn unpredictably across different playthroughs. As an important consideration, their scarcity makes systematic acquisition essential rather than relying on chance encounters. This comprehensive guide outlines multiple proven approaches to secure these elusive keys, though some reliance on randomization remains unavoidable. Before proceeding, please be aware this content includes minor spoilers regarding late-game content.

The Vault manifests infrequently during exploration sessions for good reason – successfully navigating this area allows you to accumulate an impressive +40 gold simply by collecting coins scattered throughout the chamber. When you manage to access this exclusive location, you’ll encounter numerous deposit containers, with only four being accessible through specific keys.

Blue Prince Deposit Box Keys materialize through various randomized sources across the game world:

  • Dead-end room artifacts – Isolated chambers such as the Attic house diverse item collections where Deposit Box Keys may occasionally appear among the offerings.
  • Excavation sites – While utilizing a Shovel to dig through earth mounds, you might uncover these distinctive keys.
  • Locked containers – Secured trunks and chests sometimes conceal Vault Keys within their contents.
  • Amenity facilities – Occasionally, Deposit Box Keys emerge within Locker Rooms or Sauna areas. You must first select the Pool room during drafting phases to enable these locations as potential options.
  • Key crafting specialist – The Locksmith provides a service to create Special Keys in return for currency, potentially yielding Vault Keys as the resulting product.
  • Bartering outpost – By choosing the Trading Post as an exterior chamber, you gain trading capabilities that might include Vault Keys among available commodities.
  • Recovery chamber – The Lost and Found represents a Floorplan obtainable in underground regions, automatically containing two scarce items. The significant drawback involves each subsequent entry causing the loss of one random inventory item. Pay close attention to the italicized warning: Repeated visits to the Lost and Found progressively diminish your carried possessions.
Vault Keys can appear in all sorts of locations, but they're extremely rare, too.

Strategic planning across multiple key sources dramatically improves acquisition rates despite inherent rarity.

Advanced Farming Strategy: Prioritize Shovel acquisition early in runs to maximize dirt pile interactions. Combine this with strategic outer room drafting to create synergistic farming routes that cover multiple potential key sources simultaneously.

The four distinct Blue Prince Vault Keys correspond specifically to security boxes numbered #149, 233, 304, and 370:

  • Containers #149, 233, and 304 each contain Allowance Tokens that provide permanent enhancements to your initial gold reserves.
  • Security box #370 holds paramount importance for progression, as it safeguards the essential Sanctum Key required for accessing restricted areas.
The Sanctum Key from Deposit Box 370 is the one that you're looking for.

Strategic focus on Deposit Box #370 should take precedence due to the Sanctum Key’s critical role in narrative advancement.

Progression Impact: Allowance Tokens create compounding benefits across multiple playthroughs, while the Sanctum Key unlocks essential end-game content that cannot be accessed through alternative means.

During extensive testing, securing Deposit Box Key #370 required substantial time investment and strategic adaptation. Multiple approaches were tested exhaustively, including employing an enhanced technological Shovel variant designed to uncover scarcer artifacts. Unfortunately, randomization factors consistently hindered progress despite methodological optimization.

After numerous attempts spanning several hours, successful acquisition finally occurred through optimized Lost and Found room utilization. Here’s the refined methodology from our successful implementation:

  • We acquired the Lost and Found Floorplan through underground exploration.
  • We selected the Shrine as an exterior chamber, then contributed 30 gold to obtain the Blessing of the Monk enhancement. This blessing provides a powerful mechanical advantage: Concluding daily activities within any manor room allows you to draft that same room as an outer chamber the following day.
  • We successfully drafted the Lost and Found room during an exploration cycle, though no Vault Key appeared initially. Consequently, we ended our day inside the chamber while maintaining active Blessing of the Monk status.
  • The subsequent day, we drafted the Lost and Found as an exterior room. Upon entry, Deposit Box Key #370 was positioned on the desk awaiting collection. Since we initiated our exploration with empty inventory slots, we avoided item loss penalties when accessing the room.

Common Mistakes to Avoid: Never enter the Lost and Found with valuable inventory items, as the automatic loss mechanic can sabotage carefully accumulated resources. Additionally, avoid spreading efforts too thinly across multiple key sources – focus on optimizing 2-3 reliable methods rather than pursuing all possibilities simultaneously.

Regardless of approach, we trust this detailed Blue Prince Vault Key resource enhances your future exploration attempts. Randomization mechanics can present substantial challenges, so we wish you success in locating the necessary keys for your objectives.
