Perhaps you should be more specific than "a jiggle." Key signature depends on the notes you are playing and therefore in the chords you are playing. What you just said is guitar's equivalent to asking an algebra teacher what P equals without including any constants. If you're power chords were A5, G5, F5, and C5, you would be in the key of Am or C; take your pick.
