The crystal key is created by combining a tooth half of key with a loop half of key, displaying the message, "You join the two halves of the key together." Key halves can be obtained as rewards from Barrows, the Gnome Restaurant minigame, Managing Miscellania, Treasure Trails, looting magpie implings, random events, the rare drop table, etc.
It is used to open the crystal chest located inside a house in Taverley. The chest always contains an uncut dragonstone in addition to a variety of other items. Some items of note are 3 runite bars, rune platelegs/plateskirt (depending on the player's gender), or another half of the crystal key. After the key is used, it disappears and the player must use another one if they want to open the chest again.
The crystal key may not be placed on the steel key ring, as it is non-reusable.
The crystal key can be upgraded to an enhanced crystal key at a singing bowl in Prifddinas, for the cost of 10 crystal shards.
One is required for a medium Falador Diary task of opening a Crystal chest.
