I think you do need the code to activate any fob that has not been registered to that bike before. Unless it is specifically possible to register a RFID fob (or RFID portion of an RF fob) without the code but in the presence of an active, correctly registered RF fob?
I am not sure about this but at any rate, it would be a great idea to always keep the packaging that any fob comes with just to be sure you have what you need to use that fob.

You may run into some difficulties with Dan if he thinks that all the 'CC' fob does is hold another key. Dan is going to have to program the bike to recognize the new fob. See the attachment for some detail, you may want to print it out and take it to Dan. The programming for the 'CC' fob is slightly different than the full sized fob, one step is not needed for the 'CC' fob. Again, see the attachment.
Since they seem to be clueless about this you had better tell him NOT to throw away the code numbers that come on the package of the new fob, without that number he can toss the new fob in the dumpster too.
Correction. The 'CC' fob may not need the code numbers since all it does is deactivate the immoblizer. Brian knows more about this.
