An apparatus and method designed for use with a vehicle that remotely activates an audio warning device prior to disabling the ability for the driver to start the vehicle. The apparatus is installed in the vehicle and includes a special pager receiver that decodes paging messages sent from a paging transmitter site. The pager receiver is electrically connected to a controller which interprets the coded message. An in-vehicle digital radio transmitter then sends a wireless transmission to digital radio receivers installed in the vehicle. Each digital radio receiver is incorporated in a package that includes an electrical connection to an electromagnetic relay. The relay is plugged into the electrical circuits of the vehicle which activate certain devices or functions, such as the starter motor, ignition system, power door locks, headlamps, horn, and other system that may use electrical relays. The digital radio receivers decode the transmissions from the in-vehicle transmitter and decide whether to open or close their respective relays, thus disabling or enabling certain devices or functions in the vehicle. The invention finds applicability for use by lender institutions in order to disable vehicles when the owner has not kept his account current. |
