1. Press and release to lock all the doors. Note: The interior lamps
will turn off (unless the dome lamp control is in the full-up position),
and the turn signal lamps will flash if all doors, trunk and hood (if
equipped with active anti-theft system) are closed and locked. If the
vehicle is not equipped with the active anti-theft system, the turn signal
lamps will flash if all doors and the trunk are closed and locked.
2. Press and release again within three seconds to confirm that all
the doors are closed and locked. Note: The doors will lock again, the
horn will chirp once and the turn signal lamps will flash once more.
If any of the doors, trunk or hood (if equipped with active anti-theft
system) are not properly closed the horn will make two quick chirps and
the turn signal lamps will not flash. If the vehicle is not equipped with
the active anti-theft system, the horn will make two quick chirps and the
turn signal lamps will not flash if the doors and the trunk are not closed
and locked.

 

If you are talking about a sort of subtle hollow whistle sound...then it may be the actuators trying to lock a locked door. I had a Dodge that made a sort of quick "whir" should when it tried to lock all the doors at 15 mph even though only one door was unlocked.

Is that what you are talking about...or an obvious electronic tweet sound?
