Hmm...I know the central locking system can roll down the windows, but
how can you do it without locking the doors?

My install was standard (Clifford IQ 700) and the installed just tapped
into the central locking system.  What took so long was figuring out the
double pulse.  (A single pulse is used to lock, a double to unlock.)  Once
that was done, they set the length of the pulse and all was spiffy.  When
it locks it sends the pulse long enough to roll up windows & sunroof.  And
it wasn't extra. :-)
