grease does nothing in a warded lock... to pick one you need a specifically carved pick, and a good deal of practice (i've tried several times with warded locks and can't do it- regular key locks however, i got it under 30 seconds, first try after having it explained to me)
as for the grease in cylinder locks, i've used white lightning and tri-flow... anything should work, even olive oil, but don't quote me on it... all i know is that the locks i used the two above greases on i could no longer open with a bic...
