ancient key in Fontaine. This ancient item is hidden in a chest underwater and opens the way further into the ruins of the Cross and Lily Scientific Society. After the events at the Institute of Natural Philosophy, the Traveler can unravel another mystery of the Hydro region.
In this guide, we will analyze where to find the ancient key in Fontaine, which chest to choose and how to use the quest item.
Where to find the Ancient Key in Fontaine in Genshin Impact
You can find the ancient key only on the instructions of the world "Aqueous Tidemark", in which the hero meets with a strange researcher Virgil and falls into a trap.
How to get the quest Traces of the Tide
Open quest arrival at Fontaine, it is not necessary to fulfill additional conditions for it. Meet the man in Cours de Fontaine on the fourth floor, where the statue of the Archon is located. Talk to Virgil and start the mission.
How to open a chest with an ancient key
You can get the item only at the stage xenochromic oscar.
Move deeper and find a chest in the middle of the hall, blocked by several green otters. Defeat them with the acquired Fontmer Blade skill and open the treasury, which will contain the Ancient Key.
It is needed only as part of this mission, it lies in the Inventory in the tab "Exercise". Judging by the description, he stayed in the water for a long time, but they can still open something.
If the key doesn't appear, try checking other places where it might be:
- A chest entangled with algae. Hit the glow on the plant with the blade of the razorback to free the treasury.
- The box with Mora is on the roof of the building in the northern part of the location.
- A box of mora in the seaweed in the southern part of the ruins.
How to use the Ancient Key to open the gate
Follow further along the corridor in the same ruins to the northeast and run into a wall of seaweed. Cut them in three places using the same oscar skill.
Next will be a stone blockage - to destroy it, take the ability from the one crawling nearby xenochrome armored crab and long press hit rocks with skill.
The barrier will be destroyed, and ahead you will notice a locked gate with a mechanism on the left. Swim up to him and use ancient keyto open a age further. After that, the item will automatically disappear from the Inventory, since it is only needed for the gate at the Institute of Natural Philosophy.

39k gems in inventory 😵
I searched everywhere and couldn't find the key anywhere! It is not in the chests or in the seaweed![
Have you started the quest?
I no longer have this quest, I completed it, and even finding the right place is a problem. Very unclearly noted. Swim down... Where to swim... idk
you can follow the link in the article or swim from the teleport
LOOK, if you have gone around everything and there is no key, go to any teleport, open tasks through the menu, traces in the sand and follow, hints will appear and after them you will find the key in this cave
The best advice if you lose the key (they say you went through this place and collected the chest like I did right away) is to teleport back (it’s possible to restart the game too, I personally did this, I don’t know if it had an effect or not) and then from the teleport I went down, the task crashed again where to go, and already inside the cave on the right algae appeared that need to be cut off with a special attack (I can’t explain, but I think it’s clear), and there is already a key inside and the quest will continue

Also, searched everything and ANYWHERE ITS NOT. I killed everyone, removed everything that grew, found and opened all the little things. Bad already
Can't find the key chest opened
Try to restart the game through the Paimon menu or technical
maybe you have a mistake in the guide, but I also opened the chest before the task, the key was not there. now I took the quest and found the key in the algae nearby there will be such a stray for which they give the plague. maybe someone will help.
Thank you, we will update the article
If you have already collected the chest before continuing the quest, then try to cut some seaweed with the help of the stingray ability or find a mini chest with mora, then you will drop the key from it
Thank you, we will take this into )
I found and cleaned everything and everyone. He is nowhere. I turned everything around. All have risen, chests, stingrays and mini chests. I'm going crazy already.
If not, you may have gone straight into the ruins and missed part of the quest to find traces after high tide. Try to return to the teleporter, which is a little higher, and check if there is a glowing arrow. After following all the tracks, the key appeared in the seaweed where the chest used to be
