I just purchased a 2009 Road King without the security system. I have a 2007 Sportster that has the same part number as the Road King for the Smart Security System. The FOBs are already set with a PIN number that I have with the Sporty. Can I remove the TSSM from the Sportster and install it into the Road King and think that the PIN will remain the same or will I have to return to the HD dealership to have the FOB reset? trying to save 300 bucks. Thanks.
