click unlock once and it will unlock the drivers side only. click unlock twice fast and it will unlock all doors. Press lock once it will lock doors w/o beep, press lock 2x locks w/beep.
if you unlock and do not open doors in 20-30 secs it will relock the doors. watch not to lock yourself out this way. Seems silly, but I was f'ing around and almost did that with the keys inside, myself outside.
