Thanks, Thibaud.  Will do that one day when I get my courage up :)

For the NHW20 (04-09) the RFID is only passive when the fob is in the slot
in the dash.  For smart key equipped cars the RFID is active the rest of the
time.  There are at least 4 RFID transmitters on the car. 1 by each front
door, 1 by the hatch (in the rear bumper IIRC) and 1 inside.  Each sends a
coded signal to the fob and the fob transmits back which one it "hears" the
strongest to the car (along with its serial number and the rolling code) via
the standard RKE frequency of 312 or 315 MHz (not sure which).  The car will
then only allow the proper operation to occur IE if you are standing behind
the car it won't allow either front door to unlock via the touch sensor in
the handle nor will it allow the car to power on, however it will let you
pop the hatch.

For the ZVW30 2010 they got rid of the slot and you "merely" have to hold
the fob up next to the power button to power on the car if the battery is
dead.

Pretty hard to grab a door handle when you're standing behind the car,
of course.  But yes, even if you pop the hatch, the doors remain locked.

I had been wondering about this.  I knew how to do this with the 2005, of
course, but not having a slot in the 2010 left me digging through the manual
for a half hour to no avail.  I suppose it's in there somewhere but the
index was no help.

I find that "RTFM" is of no help at all when I don't even know what the
manual calls something I'm looking for (not necessarily door locks, by
the way).  I find the manual nearly impossible to use when setting up
for use of the Bluetooth interface with a cell phone--page after page of
description, and I don't even know what they are trying to say in the
first place.
