doorlocks

Hi I parked my car on the street during a visit to the Dr's surgery to return to the car to find all the windows down and the car unlocked. (Unfortunately my briefcase was stolen from the boot). Has anyone had this happen to them? It may well be relevant to my insurance claim. Could I have been...

When I got the car it had the auto door locking set, ive since had a mess around with the settings and now it no longer works. Ive rest to factory defaults and this doesnt seem to work either, anyone similar ?
