Abstract
A vehicle security system combines anti-driveaway protection with vehicle entry signalling. Either a remote signalling device is used to generate a remote signal or an input device, mounted on the vehicle, is used to generate an access signal. An entry control unit receives and interprets the remote signal or the access signal and unlocks the vehicle doors when appropriate. At the same time, the entry control unit communicates with an engine controller that an appropriate signal has been received. In response, the engine controller enables the vehicle engine to be started so that the vehicle can be driven in a conventional manner.
