Master skeleton key

The master skeleton key was a system-wide skeleton key made by Warden Mattis Coto of the underwater Devshi prison complex to sell to criminal partners by 42 BBY After Jedi Master Mace Windu arrived to investigate Coto's criminal key making, the warden dispatched a group of the prison's droids with overidden programming to take the key to the surface and get it off of the planet Devshi. The droids took a lift to the surface and then commandeered a skiff, but Windu pursued the group and disabled the droids before they could leave Devshi, recovering the key and placing it in a vault.
