Not sure I understand your question, but the car is 100% stock. No aftermarket radio.When you put the fob near the button, it is read by a near-field radio which is a completely different system.
There are three types of communication:
1 outside the car to unlock the doors
2 inside the car (e.g. driver's pocket) to allow starting
3 near the button as a reserve way to allow starting
I don't know if 1 and 2 use the same radio system or not.
