In the captivating world of Blue Prince, players can gather three primary collectible currency-like items: Keys, Gems, and Gold. While Gold is abundant and Gems are relatively scarce, Keys strike a balance as moderately common. These essential items play a critical role in unlocking doors and various objects, allowing players to delve deeper into the manor, where encounters with locked doors become increasingly prevalent.
This guide aims to provide comprehensive insights on acquiring more Keys in Blue Prince, detailing their uses and listing the significant sources of Keys discovered so far.
This guide is designed to avoid spoilers, although it may suggest the existence of certain rooms that are not easily accessible during initial playthroughs.
Understanding the Purpose of Keys in Blue Prince


In Blue Prince, Keys serve the vital function of unlocking both locked containers and doors throughout the game. Players will encounter locked trunks in specific rooms, which can only be accessed with a Key or by using a Sledgehammer to break the lock. As players progress, the prevalence of locked doors increases, presenting additional challenges in exploration.
As players venture deeper into the manor, they will notice that the likelihood of encountering locked doors amplifies. This holds true for keycard doors as well; however, unlocking such doors requires just one keycard. Each use of a Key results in its consumption, meaning careful management is essential. Should players exhaust their supply of Keys, they may face an inconvenient halt in their game.
For those who find a Lock Pick, it offers the advantage of attempting to unlock multiple doors, albeit with a higher risk of failure. Players are advised to prioritize Lock Picks over regular Keys when possible, saving Keys for instances where the Lock Pick isn’t successful.
Strategies for Acquiring More Keys in Blue Prince




Identify Draft Rooms with Key Rewards
Several specific rooms within Blue Prince inherently reward players with Keys upon entry. Notable among these are the Storeroom, Nook, and Garage, with the Garage yielding the highest number of Keys — three, but this particular room can only appear in the West Wing of the manor.
- Storeroom: 1 Key
- Nook: 1 Key
- Garage: 3 Keys
In addition, random rooms may yield Keys without displaying an explicit indication. For instance, a Key can spawn on a desk in the Study, so always keep an eye out!
Search in Special Item Rooms, Such as the Toolshed
Certain areas including the Closet, Walk-In Closet, and Toolshed are guaranteed to contain various special items, providing players with occasional opportunities to discover Keys amidst other collectibles. While these rooms are not reliable sources, stumbling upon a Key when least expected can prove invaluable.
Solve the Dartboard Puzzle in the Billiards Room
Successfully completing the Dartboard puzzle in the Billiards room stands out as one of the most consistent methods to secure Keys. Players must solve four math problems utilizing addition, subtraction, multiplication, and division, presented in multiple colors.
By accurately addressing all four problems, gamers unlock a hidden compartment behind the dartboard, which can yield not only regular Keys but also unique items like the Key to the Secret Garden or even a Keycard. Frequently, solving this puzzle results in a reward of two Keys.
Acquire Keys from the Locksmith and Other Vendors
Keys can also be purchased from the Commissary and the Locksmith shops in Blue Prince. The Locksmith consistently offers Keys for sale, while the Commissary’s inventory varies between playthroughs, so it may not always stock Keys. Both shops occasionally feature single and bulk Key packs, making it wise for players to conserve Gold for these purchases.
Typically, the Locksmith can be found in the manor’s later sections, specifically ranks 5 and above, while the Commissary can appear at all ranks.
Unlock More Keys from Locked Trunks and Other Containers
As players explore the manor, they will come across locked trunks that require either a Key or a Sledgehammer for access. Despite the initial hesitation, these trunks carry a high possibility of containing Keys, making it sometimes beneficial to use a Key to unlock them, especially when the player has a surplus.
Alternatively, a Sledgehammer can be found in Green Rooms, particularly the Conservatory, or can be purchased from certain shops. Acquiring a Sledgehammer allows players to bypass spending a Key on locked trunks.
Unlock Keys through Constellation Rewards
By consistently exploring the Observatory room and increasing Star counts, players can unlock bonus rewards, including Keys. One significant constellation, ‘Clavis, The Key’, grants a bonus of +1 Key upon discovery, requiring a minimum of 8 Stars, necessitating at least eight visits to the Observatory.
As gameplay advances, players can observe multiple constellations simultaneously through the telescope, and the key reward from Clavis can reappear even if the player has surpassed the 8-Star mark. Regularly checking the Observatory can thus yield diverse free items and meaningful long-lasting bonuses that may impact a player’s journey.
