Complete guide to finding Simple Keys and unlocking doors in Hollow Knight Silksong with advanced strategies
Understanding Simple Keys in Silksong


The Simple Key in Hollow Knight Silksong represents one of the most crucial early-game investments for progression-minded players. While the item description remains deliberately vague, these metallic implements serve as your ticket to bypassing environmental barriers and accessing hidden regions. Unlike consumable items, Simple Keys are permanent additions to your inventory once acquired, allowing strategic planning for multiple locked encounters throughout your journey.
New players often underestimate the value of these keys, but seasoned adventurers recognize them as gateway items that can dramatically alter progression routes. The initial cost may seem prohibitive, but the long-term benefits of early area access and hidden loot far outweigh the Rosary investment required.
Simple Key Acquisition Guide
Securing your first Simple Key requires navigating to Bone Bottom, the initial settlement encountered after passing the Chapel Maid checkpoint. Within this hub area, seek out the local merchant among the various NPCs and browse their wares carefully. The Simple Key appears on their inventory list for 500 Rosaries – a substantial early-game sum that demands strategic resource management.
Alternative Key Locations:
Pro Tip: Prioritize the merchant purchase first, as the 500 Rosary key unlocks early access to Wormways – an excellent Rosary farming location that quickly recoups your investment.
Advanced players should note that certain keys become unavailable if specific story progression thresholds are passed, making early acquisition crucial for completionist runs.
Locked Door Locations & Solutions
Wormways Access Point: Begin by activating the Bone Bottom cage elevator mechanism, then ascend to the northwestern sector of Mosshome. The path requires precise platforming across suspended metal cages. Time your attacks on flying insects to gain aerial momentum for reaching distant platforms. After conquering the area’s guardian, a locked door on the left reveals the Wormways – a subterranean network rich with resources.
Lava Chamber Challenge: Navigate to the junction between Deep Docks and Far Fields near the Forge Daughter’s workshop. Descend one level, take the rightward path, then ascend toward the molten floor. The Swift Step ancestral technique proves essential for crossing the lava flow safely before using your key on the opposite side.
Green Prince Rescue: The key discovered in Sinner’s Road’s upper passages corresponds directly to a captive’s cage below. Descend from the key’s location to find the imprisoned Green Prince, whom any Simple Key can liberate. This optional rescue mission often yields valuable alliances or future benefits.
High Halls Treasure Vault: Within the Citadel’s High Halls district, an Ornate Lock blocks access to vertical ceiling passages. Successfully navigating these columns rewards explorers with substantial loot, including the powerful Rosary Cannon, though hostile encounters demand combat readiness.
Advanced Strategies & Optimization
Rosary Farming Efficiency: Before purchasing keys, establish efficient Rosary gathering routes in Mosshome and Bone Bottom. Defeating respawning enemies and breaking environmental objects yields consistent income. The Wormways area, once unlocked, offers superior farming opportunities that quickly offset key acquisition costs.
Common Beginner Mistakes:
Sequence Breaking Potential: Strategic key usage can enable experienced players to access late-game areas prematurely, obtaining powerful upgrades before intended story progression. The High Halls treasure vault particularly offers gear that can dramatically ease mid-game challenges.
Movement mastery remains essential – practice advanced techniques like aerial deflection and swift step navigation in safe areas before attempting dangerous key-related platforming sequences.
