An apparatus for remotely communicating with the vehicle to control functional circuits in the vehicle. The apparatus includes a pager based communication apparatus mounted in the vehicle for receiving a command signal from a pager service provider in response to a user generated telephone number, security code and a command. A microcontroller is responsive to the received command and, in response to a stored control program, generates outputs to various vehicle functional circuits. The microcontroller generates outputs in response to selected user generated commands to deactivate the vehicle engine in the event of a hijack command when the engine RPM drops below a prestored engine RPM magnitude. The microcontroller is also capable of generating outputs to control engine starting and stopping, door lock and unlock operations, and other vehicle accessories.
