Jerry,
I'm an RF guy or was from 1967 - 2004.
Since I'm not about to cut open my key, my best guess is it uses a form of Passive Integrated Technology, the same tech as used in Dog/Cat microchips.
If BRP is in fact using a form of PIT the key DOES and MUST transmit, obtaining it's power inductively from the RF sent out by the Spyder.
Check out Passive RFID on the net and it should give you the technical aspects of how it works.

Hi Bob,
Re: The key doesn't transmit anything
I graduated with the class of '71 with a degree in Mech Engr, so it has been a long time ago. Also, I was NOT the brightest person in my class.
However, I do know that to transmit/send requires a power source in some form. That is not up for discussion.
As for Spyder keys, consider a LEO's radar gun. The gun transmits but your car does not. So how does he know how fast you are going? It is the bounce back; his radar gun is taking a reading.
I do not know a lot about RF systems but I do know that my local library, which has RF 'devices' imbedded/glued in the books, uses it when I checkout a book or turn one in. Those books do not contain any batteries; but they do have a 'device' that the RF reader detects.
While I may be wrong, I think this might be how our keys work.

PS) I recently ordered a 2nd backup key for my Spyder. The key supplied was a Aprilia-type key. When I got it, it would not work. So the company sent me a new chip only, to install myself. That key works great now. But that chip did not have a battery.
