sorry to hi-jack, but i'm well sussed when it comes to cars locks etc!
my
ibiza's remote does this, and may
help your questions
one click lock - all doors are locked, deadlocked & alarm fully operational inc interior movement sensor
two click lock - all doors locked, not deadlocked, but perimeter alarm operational (grab the interior door handle, it will open after second pull, but alarm will sound)
one click unlock - drivers door only unlocks, alarm & deadlocks dis-armed
two click unlock - all doors inc boot are unlocked
also a handy hint for everyone out shopping or the like, once you've reached your destination, open your boot (make sure everyone and everything is out of the passenger cabin) one click lock (boot lip still open) this locks the main passenger cabin, once boot lid is shut, the deadlocks and alarm are then activated, one flash from the indicators signifies this.
