my understaning, could be wrong, is that there are two systems.
a) keep key in pocket, push start button, drive off
b) put key in key slot, push start button, drive off
I am sure that wrx is right. The model I saw in the show room had a slot in the dashboard for the key and a start button. The Advanced Key, as they call it in the brochure, "allows the driver to keep the key in their bag or pocket at all times"I have been told today that the start button is only installed if you buy keyless entry. If you dont, then you dont get the button.
All the pictures I have seen show the start button. Including the ones with the key sticking out of the dash board.
