A stone key imbued with the power of magic, the Imbued Sword Key is a unique item in Elden Ring that is used to open special teleporters in the Four Belfries area.
The Four Belfries area can be found in the western region of Liurnia. Upon accessing the area, you will need three Imbued Keys to unlock the portals. One to the past, one to the future, and one something in between.
Imbued Sword Keys can only be used and are lost upon use, just like the Stonesword Keys. This makes them rare but luckily they can only be used on specific places, thus eliminating the pressure of decisions.
In this guide, we will help you locate all four Imbued Keys from both the base game and the DLC.
Four Belfries Location in Elden Ring

The Four Belfries are located in the western region of the Liurnia of the Lakes. You can visit them while traveling towards Caria Manor. To reach this area, start from the Academy Town Gate site of grace, next to the Academy of Raya Lucaria.
Head northwest and hug the large wall. Make sure that you are riding Torrent, as you will need it to make the spring jump. Once you reach the upper landmass, travel north across the village of Fire Monks to reach the Four Belfries area.
You can also reach your desired location by moving near the Village of the Albinaurics. As there is no path through the Village, hug the wall to the left until you come across the Converted Fringe Tower. You can solve its puzzle to gain an additional Memory Stone, an important item for Sorcery builds.
After obtaining the stone, stay on the north track toward the mountains. There you will find the Site of the Grace for the Four Belfries.
There are three portals that you must unlock in the Four Belfries area. For this purpose, you must find at least three Imbued Sword Keys, spread across the Lands Between.
Imbued Sword Key #1 – The Four Belfries

The first Imbued Sword Key can be found in the same area where the Four Belfries are. Evade the enemies and make it to the top of the hill with an inactive teleporter.

There is a treasure chest beside the teleporter. Open it to collect the first key.
Imbued Sword Key #2 – Raya Lucaria Academy

The second Imbued Sword Key can be looted from a dead body on the rooftops of the Academy of Raya Lucaria. Make your way across the academy until you reach the Debate Parlor and defeat the Red Wolf of Radagon.

Go outside the parlor and turn left. You will notice some rubble to the left. Climb the rubble and defeat two sorcerers. Turn left to find a railing with a dead body. Climb over it to reach the rooftops. Drop down and travel east to locate a dead body with an item.

This is the second Imbued Key. Beware of the Marionette Soldiers in the area, as they are hiding and can attack you from afar.
Imbued Sword Key #3 – Sellia, Town of Sorcery

The third and final Imbued Sword Key of the base game can be found in a treasure chest in Sellia. This town of sorcery is located in the southeast region of Caelid, the red area on the map.
However, the treasure chest with the key is locked behind a magic seal. To open this magic seal, you must solve the puzzle of Sellia. Climb the rooftops with the help of Torrent and light three braziers. This will unlock all the paths in Sellia.

Go to the northeast area of the city, and you will find a small treasure chest holding the third imbued key.
Imbued Sword Key #4 – Castle Ensis

The fourth Imbued Sword Key has been added with the Shadow of the Erdtree DLC. To find it, go to Castle Ensis and make your way to the top of the tower. Defeat the Moonrythill, Carian Knight, and go to the section behind him.
Follow the path to the right until you exit Castle Ensis. Open the metal gate and follow the main path up. Turn northeast to find wooden stairs to the upper floor. Make a quick turn to find a small treasure chest in an alcove. Open it to obtain the fourth imbued key.
How to Use the Imbued Sword Keys
You can unlock all the teleporters in the Four Belfries’ different towers to reach new and adventurous locations in Elden Ring.
The first Belfry Tower takes you to the secluded area of the Crumbling Farum Azula in Elden Ring. There you will find two Azula Beastmen that you can fight to test your skill and obtain the Pearldrake Talisman after the successful conclusion of the battle. This will be your glimpse into the future.
Make your way toward the second teleporter to reach the Chapel of Anticipation. Here you will encounter the Grafted Scion if you have not already accomplished that. This is a journey back to the past, one you must take to complete Nepheli Loux’s quest by finding the Stormhawk King’s ashes.
Defeat this boss to obtain the Ornamental Straight Sword and Golden Beast Crest Shield. You can also collect maiden’s blood from this area to progress Varre’s quest to reach Mohgwyn’s Palace.
With the last Belfry Tower, you get yourself teleported to the Nokron, Eternal City, in Elden Ring. In this area, you can only fight a Crucible Knight (with the toad power of flame) to obtain the Mottled Necklace Talisman.
