Have you got any date for delivery yet?
I have already been looking at the online users manual at Porsche iManuals but it does not seem to be possible.
Double clicking the fob should lock the car but deactivate part of the alarm system (for use on ferries or if pets are left in the vehicle).
My dad has a Mercedes W213, and on that it is possible to deactivate the fob, this is in my mind a feature that should be possible on all cars with keyless entry.
