The antenna for the E-key is supposed to be under the front part of the rear seat. I can't determine if there's an antenna in that location or not.

Your bike would not start without that antenna. The same antenna is used for the fob and emergency key.
The product data (Owner's Manual) refers to two antennas. The electronic immobilizer is supposed to utilize a ring antenna on the ignition switch that communicates with the fob with a separate ring antenna located under the seat. The system may very well utilize both antennas, but the manual notes that the bike won't start if the fob is too far away from the antenna (approx. 1 m). It specifically notes that this can happen if the fob is in the top case or pannier. All of this implies to me that the antenna at the ignition switch is for the fob and the seat antenna is for the E-key, just based on the geometry. Again, the system may very well use both. I'm a FNG and will defer to those who know. I will look closer. Thanks for the help.
I did not know there were two.
You do need the one under the seat. If the battery in the fob is dead you place the fob on the antenna under the seat.
