You’re wandering through the Queen’s Gardens, dodging those annoying mantis traitors, and you stumble upon a corpse. It’s not just any bug; it’s a massive, overgrown hunk of shell holding an item that looks suspiciously important. This is the Hollow Knight Love Key.
Most players find it by accident. Honestly, the first time I played, I sat there staring at the inventory description wondering what on earth "Love" has to do with a kingdom as depressing as Hallownest. Team Cherry loves to hide these bizarre little thematic nuggets in the corners of the map. You pick it up, see the pinkish glow, and then... nothing happens. You can't use it in the Gardens. You can't use it in the City of Tears. It just sits there.
Getting this key is basically a rite of passage for anyone trying to actually finish the game’s completion percentage. It’s not optional if you want the "good" stuff.
Where the Hollow Knight Love Key is Hiding
So, you need the location. It's tucked away in the southeast corner of the Queen's Gardens. If you’ve found the Moss Knight or the area near the stag station, you’re close, but you need to head toward the border of the Fog Canyon. Look for a room that feels a bit more "acidic" than the rest.
There’s a dead bug. A big one.

The corpse is actually a "Love Key" holder, though the game doesn't give him a name. He’s just a tragic figure in a garden full of them. To get there, you’ll definitely need the Isma’s Tear ability because the acid pools in that area are a nightmare. Without it, you're just going to melt before you even see the glow of the key.
If you're coming from the City of Tears side, you're going the wrong way. This is a common mistake. Players think because the lock is in the City, the key must be nearby. Nope. Team Cherry made sure you had to trek across the entire map. It’s a deliberate design choice that forces you to explore the lush, green (and deadly) parts of the world before returning to the industrial heart of the kingdom.
That Secret Door in the Tower of Love
Once you have the Hollow Knight Love Key, where do you go? You head to the City of Tears, specifically the eastern side near the King's Station. There is a hidden path. It’s not marked on the map until you actually walk through the wall.
Look for a breakable ceiling or a side path right before the station. This leads you to the Tower of Love.
The door is distinct. It has a specific indentation that matches the key. You use the key, the door creaks open, and you enter one of the creepiest sub-areas in the game. The music shifts. It gets high-pitched and frantic. It feels wrong. That’s because the Tower of Love is home to The Collector.
The Collector is a void creature. He’s obsessed. He wants to "protect" the creatures of Hallownest by stuffing them into glass jars. It’s a twisted version of what the Knight does with the Grubs. While you’re saving them, the Collector thinks he’s saving them too—by keeping them in a state of eternal imprisonment.

Beating the Collector (The Real Reason You're Here)
The fight isn't the hardest in the game, but it's chaotic. He jumps around like a maniac. He drops jars from the ceiling. Out of those jars come Aspids, Baldurs, and Vengeflies. If you don't have the Pure Nail or at least a few upgrades, the screen gets cluttered fast.
- Quick Focus is a lifesaver here.
- Mark of Pride helps you swat the adds before they touch you.
- Shaman Stone is great for blasting the Collector when he’s vulnerable.
Basically, stay mobile. If you stand still, a jar will crack over your head and you'll be fighting three enemies at once. The Collector himself has a strange, spindly hitbox. Aim for the center.
The Ultimate Reward: The Collector’s Map
Why go through all this trouble? Why hunt down a key in a garden and fight a lanky void monster in a tower?
The map.

After you defeat the Collector, you go up to the top floor. You’ll find a few trapped Grubs (obviously), but the real prize is the Collector's Map. This isn't just a regular map update. This marks every single uncollected Grub on your main map.
If you are going for the 112% completion or trying to get the Grubberfly’s Elegy charm, this is the most important item in the game. Hunting Grubs without this map is an exercise in futility. You’ll be checking every wall in the Deepnest for hours. With the map, you just look at your screen, see the icon, and go.
Context and Lore: Who Made the Key?
There’s a bit of a debate in the lore community about the origin of the Hollow Knight Love Key. The key features a symbol that looks vaguely like the Kingsmoulds or the Royal Retainers. Some players argue that the Collector was a failed experiment by the Pale King, an attempt to use Void for a specific purpose that went off the rails.
The fact that the key was found in the Queen's Gardens—the White Lady's domain—suggests a link between the royal family and the Collector's imprisonment. Did they lock him away because he was a nuisance? Or was he once a servant who became obsessed with "preserving" the kingdom as it fell to the Infection?
We don't get a straight answer. Hallownest is a graveyard of half-told stories. But the physical evidence—the key being held by a bug in the gardens—proves that someone wanted that door to stay shut.
Common Troubleshooting
I've seen people get stuck because they can't find the entrance to the Tower of Love even with the key. Remember: it is located between the Kingdom's Edge and the City of Tears. You usually have to enter from the Kingdom's Edge side to reach the front door. If you’re coming from the King’s Station, look for the vent-like openings in the wall.
Also, some players think the key is a one-time use. It is. Once the door is open, the key disappears from your inventory. Don't panic; you don't need it for anything else.
Actionable Next Steps for Your Playthrough
If you’re currently staring at your screen wondering what to do next with that weird pink key, here is your checklist. No fluff. Just do these things in order:
- Check your abilities. Ensure you have Isma’s Tear (from the Isma’s Grove in the Royal Waterways) and the Mantis Claw. You can’t reach the key's location in the Queen's Gardens without being able to swim in acid.
- Locate the Key. Travel to the bottom-right of the Queen's Gardens. Look for the large, glowing corpse. Interact with it to pick up the item.
- Travel to King's Station. Use the Stagways to save time.
- Find the Tower. Exit the station to the left, go down, and look for the hidden path leading right, toward the border of Kingdom's Edge.
- Unlock the Door. Use the key on the ornate lock.
- Equip Combat Charms. Before heading up, equip charms like Fragile/Unbreakable Strength or Quick Slash. The Collector moves fast and drops minions constantly.
- Claim the Map. Defeat the boss, head to the upper room, and grab the Collector's Map.
- Grub Hunt. Open your main map ($M$ or your controller equivalent) and look for the new icons. These indicate the Grubs you’ve missed.
By finishing this sequence, you’ve effectively cleared one of the biggest hurdles to reaching the endgame. The Grubs provide significant rewards, including Pale Ore and several powerful charms, so getting that map is a massive power spike for your character. Don't put it off. The Collector is waiting, and those Grubs aren't going to save themselves.
