Change WidgetLocker Lock/Unlock Tone?

Hi I need help changing my lock and unlock tone for widgetlocker I've tried various methods and don't seem to get a wav/mp3/mp4 file to play as its notification/ringtone when i lock and unlock the phone.

I think thats on the phone settings itself, not the widgetlocker settings.
