ABSTRACT:
An alerting device for an vehicle includes a sensor which senses the position of the movable locking knob of the vehicle and provides a switch output to a circuit which produces an alerting sound when the door locking knob has been opened. In one form thereof, the door locking knob is replaced with a structure which movably supports a magnet which moves between a position which is near a magnet sensor and a position where it is away from the magnet sensors. When the door locking knob is moved to the open position, the magnetic sensor senses its condition and causes the circuit to output an audible alert.
