The crystal key is used to open the crystal chest located inside a house in Taverley. It 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." The crystal key can only be used on the chest once. After it is used, it disappears. Some notable items that can be obtained from using one key are 3 runite bars, rune platelegs or a crystal key half. The chest has a 100% chance of giving an uncut dragonstone.
Tooth and loop halves can be obtained as rewards from Barrows, the Gnome Restaurant minigame, Managing Miscellania, Treasure Trails and random events.
This key may not be used with the steel key ring, which is only for reusable keys.
