a HUGE shout-out to lather. He suggested I talk to Chris at Short Tronics in MN. I told Chris that my 2010 bike's fob got run over, but the circuit board looked fine to the naked eye. He suggested moving the main chip to the circuit board of a new fob, or a used one known to be working. Lather happened to have an old 2008 fob he wasn't using!!!
IT WORKED.
The 2008 transponder part number is different from my 2010, but the mitsubishi number at the bottom of the circuit board matched, and everything else seemed identical. And it worked.
THANK YOU lather and also everyone who contributed info.
Now I am wondering if I can get the passive chip from that 2008 fob "paired" to my bike so I have a backup. I know ID codes are needed to do this with the active transponder, but what about the passive one?
The passive chip in my 2010 must have popped out and I couldn't find it on the side of the road. So I have no backup currently.
