Pyrrha's conversation with Jaune clearly suggests Aura is used even when a person has not unlocked it. The whole "you ever felt someone was watching you" thing. I also imagine people can unlock it or use it even when they are not trying. A person in mortal peril might activate his or her Aura unconciously.
