There will be a code in the owners manual they are all set the same from the factory. Has to do with left and right turn signals.
magoo - not quite true... from the
factory all the PIN codes are set to Zeros: 00000
On '06 and earlier, you could assign (push-button) fobs without changing the PIN from 00000, Problem with that is, there are no Zeros available by (left = #, right = ENTER) pushing the turn signal buttons, only 1 through 9, so if the dealer didn't put SOMETHING in, and your bike was armed and you didnt have your fob (or it quit working) you were kinda

screwed. Some dealers put a default number in, some ask you for a number before or during delivery of your bike.
It is common to put the code in the owner's manual. If it's not there, and you don't know (or don't remember

) it, call your dealer. Maybe it's set to his default or recorded the code in your paperwork. In any event, if yours is set to the dealers default, you should change it for obvious reasons.

On '07-later, when you program the (button-less) FOBs, you HAVE to enter SOMETHING for a PIN. The system will not let you leave them ZEROs. So if your 'Hands-Free' FOBs work, there IS a PIN stored. Again, if yours is set to the dealers default, you should change it.
grc - I should have said: The EASIEST way to reset the PIN is with a DIS-armed system, etc...
