A mobile detection and alert vehicle tracking and security system for an individual vehicle as well as a plurality of individual vehicles in a given security area. The mobile detection and alert system provides round-the-clock vehicle security, allowing immediate response in case of vehicle theft, an accident, vehicle breakdown, or other emergency. Guardian and tracking functions are provided through keyboard control units which are installed in vehicles to be monitored. The keyboard control units communicate with a central monitoring facility in at least one-way, and preferably two-way, communication. Preferably, the keyboard control unit provides vehicle theft and intrusion protection using an in-vehicle alarm and security system linked to the central monitoring facility by a transceiver in the keyboard control unit.
