But I can take the electronics alone, without the grain-of-rice transponder, and unlock and start my car!!!! (The siren module in this car has a dead/non-chargeable battery that needs replacement, but other than that, there are zero VIDA DTCs set.)
I cut the old one apart, and transferred the guts to the new plastic, with buttons that had color on them. But the grain of rice transponder... I wondered where I could put that INSIDE the keyfob, so that I could cut off the plastic "neck" of the key, and just use the "knob" key that I leave in the ignition, so I temporarily taped it to the side of the case, and went to start the car, and started it. But I realized that I had taped the transponder to the case I had left on the workbench, and had just started the car without ANY transponder at all.
The photo below shows, starting at top left, and going clockwise, the transponder, the knob, which one assumes must have its own transponder, the top of the new keyfob case, and the bottom of the keyfob case, WITHOUT the transponder installed in the recess of the fake "key" part of the keyfob.

Now, on previous drives, using the knob, and keeping the keyfob in my pocket, if I get out of the car with the engine running and walk away any distance, the car detects that the keyfob has left the car, and chimes and complains about that. So the car knows electronically, far beyond the range of the grain of rice, which explains how I can open locked doors with the keyfob in my pocket by simply approaching the car. But is the grain of rice "chip" now obsolete? Why is it included then?
I am so very confused. No way that the previous owner modded anything in this car, he had everything, even tires, done at the stealership. There is no way that there is an extra grain of rice chip "inside the coil" behind the dash.
How can this chipless fob be starting the car? I am afraid to cut off the fake-o "key" part of the fob as I wished (to make a more pocket-friendly keyfob).
