The car does not lock the doors after getting out of the vehicle on it's own. The only time that I see it doing this is when I touch the handle (or washing around the handle) but do not open the door… the car seems to lock itself again.
***Thank you! At what situation would it lock by itself? I'd be disappointed if does not do the job, since most Toyota would lock itself after a minute or so, assuming you forget to lock your car.
