You do it once, and only need it done to change codes for cable box, wasn't needed to enter say a tv code. The 982 procedure is a toggle, do it once it unlocks, do it again and it locks. All you need to make sure is after doing it and you get 4 blinks, never do it again. Only cable companies care if the code is locked in, they don't want calls about cable remote no longer controlling the supplied box.
