A Hornet's Guide to Every Simple Key in Silksong
Find every Simple Key location and Simple Lock use in Hollow Knight: Silksong with this concise Pharloom guide.
I still remember the first time I saw a Simple Lock in Hollow Knight: Silksong. It was a smug little door in the Deep Docks, and I had no key. I had Rosaries, a needle, and a bad attitude, but none of that mattered. What good is a key if you forget where the lock is? And what good is a lock if you never find the key? As of 2026, Pharloom has not gotten any kinder, so I am writing down every Simple Key location and every Simple Lock use I have found, so you do not have to backtrack through a thousand crawling tunnels like I did.
Simple Keys are single-use, which is why I treat each one like a precious secret. There are only four in the game, and each one opens a specific door. If you waste one, you will feel it. So let us walk through the keys first, then the locks.

Find Jubilana, then unlock her at First Shrine1. Bone Bottom: Pebb's Price
The first key is the easiest to understand and the hardest to afford early on. I walked up to Pebb the merchant in Bone Bottom, and he wanted 500 Rosaries. That felt like a fortune when I was still learning how to survive. I farmed, completed wishes, and scraped together the cost. If you are short, do not rush into every locked door you see. Trust me, the key is not going anywhere.
2. Sinner's Road: The Top-Floor Ambush
Sinner's Road taught me that vertical exploration is its own kind of horror. The second Simple Key sits in the top northeastern corner. You need the double jump or the clawline to cling to walls and climb to the top. Hit the lever to access the top floor, and then get ready. Hornet is ambushed by a big enemy. I died twice before I learned its rhythm, but defeating it rewards the key. Who would have thought a simple climb could turn into a boss fight?
3. Sands of Karak: A Dead Bug's Gift
The third key is a test of speed and nerve. In the Sands of Karak, I had to hit a branch and move quickly before the path disappeared. Once I was far east, I kept going in the same direction until I reached a bench with a body on it. I grabbed the Simple Key from the dead bug. It is grim, but in Pharloom, grim is just another word for Tuesday.
4. The Wandering Merchant: Jubilana's Final Key
The last key comes from The Wandering Merchant quest. I found Jubilana, then returned to the First Shrine to unlock her as a merchant. After collecting 650 Rosaries, I bought the Simple Key. It is expensive, but by this point you should have a decent Rosary route. If you do not, hunt down wishes and sell what you can spare.
Where to Use Every Simple Lock
Now for the part that actually matters. A key without a lock is just a shiny regret. Here is where I used each one.
Deep Docks: The Bellway Door
From the Deep Docks Bellway, head right to the lower door. Attack the lever to go down deeper and enter the path below the Forge Daughter. At the end, there is a locked door that reveals a huge part of the Deep Docks. You can access this area later from Far Fields after acquiring certain abilities, but using the Simple Key here gives you a head start with exploration. I chose the early route, and it paid off.
Sinner's Road: The Green Prince's Cage
In the vertical room right next to the bench where Shakra is singing in Sinner's Road, I found the Green Prince imprisoned in a cage. Climb a few cages, then glide down the left to access the Simple Lock. The NPC asks Hornet not to free him, but you have to do it to trigger his quest. Sometimes being a hero means ignoring good advice.
Wormways: The Alchemist's Assistant and Sharpdart
Upon accessing Wormways, keep going left while avoiding the falling worms until a door eventually appears. This opens more parts of the area, lets you complete the Alchemist’s Assistant quest, and unlocks the Sharpdart skill. That skill is hidden behind a Needolin door that can only be reached by using the clawline and double jump abilities.
Sharpdart is worth the trouble. It changes how you move and fight, and it makes some later platforming sections far less cruel.
High Halls: Rosary Cannon and Pale Rosary Necklace
The door in High Halls is easily accessed from the station location. Unlock the door and head inside to find an obstacle blocking the path leading up. Destroy and navigate the tunnels while avoiding the deadly wheels until you reach the end. There are two paths available. Head down first to get the Rosary Cannon, then go up to collect a lot of Rosaries and open a chest containing the Pale Rosary Necklace. I went up first once, and I regretted it. Learn from my mistake.
Final Thoughts
Simple Keys are not just items. They are choices. Each one forces you to decide which part of Pharloom you want to open early, and which part can wait. In 2026, with more players than ever crawling through Silksong, I still see the same question: where do I use this key? My answer is simple. Use it where it hurts least to wait, and where it helps most to explore now. For me, that meant Deep Docks first, then the Green Prince, then Wormways, and finally High Halls. Your path may differ, but at least now you know where every key hides. Good luck out there, and do not waste your Rosaries on regret.
If hunting down four Simple Keys taught you anything, it's that patience and a bit of planning stretch your resources further than impulse ever will. The same logic applies to building your library. Most of us have a wishlist full of games we'd happily play right now but not at full price, and waiting for the right moment to buy is its own kind of sequence break — you skip the sting and still get where you wanted to go. That's exactly the problem [cheapest steam keys]( was built to solve, gathering discounted keys from reputable sellers into one place so you're not tab-hopping between storefronts comparing numbers.
DealNest keeps that comparison quick: browse current listings, check the price against what you'd pay on Steam directly, and buy only when the discount actually justifies it. It won't tell you which metroidvania to play next, but it can make the backlog cheaper to build while you wait for the next patch, DLC, or sale. Think of it as one more lock worth opening early — the only difference is that this one saves you money instead of Rosaries.
