Abstract
A theft warning system for use in a vehicle, which issues a warning to protect vehicle contents when a vehicle door is opened without use of a door key. The theft warning condition is set only when all doors are closed while all the door lock devices are locked. The theft warning system generates a theft warning signal when the final open door is closed and locked without use of a door key and one of the door lock devices subsequently is unlocked without a door key.
