# Spawner Keys [Spawner Keys](https://reasonfounddecoy.gitbook.io/mctantrum-wiki/economy/bits-heads-and-spawners#heads-for-crafting-purposes) are crafted with any [Key Fragment](https://reasonfounddecoy.gitbook.io/mctantrum-wiki/economy/bits-heads-and-spawners#bits-for-crafting-purposes) (regardless of the type of bits you used to make it) and the type of mob heads respective to the spawner you intend to get. For instance, you can make a Key Fragment using Enderman bits and use it in a Spawner Key recipe with Ghast heads and it will create a Ghast Spawner Key. {% hint style="info" %} Spawner Keys are craftable at **any** time and have no cooldown to craft them, however the ***usage*** of the key at the crates has a ***shared cooldown***! If you use a key on a spawner crate, you will not be able to use any other Spawner Key on any other Spawner Crate for 8 hours. You can view your cooldown status on your quickboard. {% endhint %} {% hint style="warning" %} Although these keys can be crafted at any rank, you will not be able to warp to Spawner\_Crates or use the key there until you reach Wither rank! You can also see if another player will craft it for you/open the crate for you. {% endhint %}
