As an aged and experienced wizard, Merlin undoubtedly is capable of many supernatural feats, but apparently, simply placing a key into its lock is not one of them. To be fair, the Crystal Key you receive from Ursula during โWith Great Powerโ in Disney Dreamlight Valley isnโt your typical key, but alas, thatโs why youโre considered the โsaviorโ of the Valley, right? Who but you, the Dreamlight Valley protagonist, would know how to place Ursulaโs Crystal Key at Dazzle Beach?
Where To Use the Crystal Key at Dazzle Beach โ Dreamlight Valley Location

The spot you need to place Ursulaโs Crystal Key at Dazzle Beach in Dreamlight Valley is just south of the narrow pathway connected to Peaceful Meadow. Just go down the slope, turn right, and hug the wall until you reach the entrance to the Mystical Cave, aka the โcursed cave.โ The area is small, so itโs impossible for you to miss it. To further clarify via the Map, investigate the spot right below the Meadowโs grassy outcropping.
Once you arrive, interact with the Ancient Device, a small pillar-shaped interactable outside the cave. Your inventory will open up, and you can plop Ursulaโs Crystal Key into the Dazzle Beach caveโs device and voilร โ open sesame! Unlike what you encounter inside the cave, thereโs no puzzle tied to using the Crystal Key.
