John's correct. When an HRC card is ordered the supplier requires the PIN number (on a little silver sticker on the PGM-IV case behind the instrument cluster) to ensure it is coded correctly.

If any HRC (or stock) card worked with any MC28 PGM-IV you could imagine what problems it would create! Imagine a "one ignition key fits all MC21's" scenario... it would be like a step back in time to the era of RD125's and pennies for keys! lol
