The Orokin Vaults e.g. Orokin Derelict Exterminate: You must have 1 of the four Dragon Keys equipped to unlock the vault. There is only 1 vault per mission. It is recommended to go with a team of four each with a different Dragon Key equipped to maximise your chance of being able to unlock a vault. Vaults are off course of the objective so you must search each and every nook and cranny of the map. If you solo the mission looking for a vault there is only a 25% chance of having the correct key to unlock it.

Dragon Keys - Required to open a vault.

Orokin Derelict - Where the vault is found.
