SYSTEMS AND METHODS FOR PREVENTING CAR THEFT

Methods and systems are disclosed for receiving, by a receiver, a first signal sent from a remote access device; and, in response to the receiver receiving the first signal, causing, by a processor, an electrochromic device of a vehicle windshield to be in a turned-on state. A transmitter sends a second signal to a remote authenticator device, the second signal triggering a response signal from the remote authenticator device. The receiver receives the response signal. In response to the response signal indicating an authorization the processor causes the electrochromic device to be in the turned-on state. In response to the response signal indicating no authorization, the processor causes the electrochromic device to be in a turned-off state. Sometimes the electrochromic device is turned-on when, in addition to receiving the first signal, the receiver receives the response signal from the remote authenticator device indicating an authorization.
