While in a turkey induced semi-coma last evening, I got to wondering about how the keyless proximity FOB works. Does the FOB constantly transmit a signal, or does the ECM constantly transmit a signal that activates the FOB when it is in range? What kind of signals are involved (IR, radio, microwave), and what is actually "switched on" in the ECM to allow starting? Will the FOB battery go dead quicker if it is always kept close to the bike? Evidently as I age, the tryptophan in turkey, affects my brain like THC did in the 60's.
