Nope, the smartcard contains the master key which is easily changed (Virgin are changing their master keys a number of times a day now). A key change does not require a new card. NDS fundamentally changed Skys encryption, hence the need for new software in both Sky STB's, and in the Proffesional receivers in the super and regional headends, and new smartcards. Escapee or Stu038 may remember the big job ntl had with upgrading the professional receivers for Skys P2 change.
