Hi It was I who sent you the message through ebay maxalisen what I said was that the key will have number on the back of it, where you put the key into the ignition is the pgm unit and it must the same number as your key on the back of the pgm to run the bike .When you buy a key new you have to send the number on the back of your pgm unit to honda or tyga and they send out a key that is coded to you bike and pgm .If you selling it your hopeing someone out there has that number on the back of there pgm
