  • Multistage vehicle security system
    Patent number: 6891467
    Abstract: A multistage vehicle security system includes a transceiver that receives a first signal sent from a transponder and a controller that processes the first signal. The controller activates low level operational features of the vehicle if the signal is associated with an authorized transponder. The system also includes an entry sensor that detects the physical presence of a user. The transponder sends a second signal to the transceiver when the presence of the user is detected. The controller processes the second signal and activates midlevel operational features of the vehicle if the second signal is associated with the authorized transponder. Once the user is inside the vehicle, a sensor detects a biometric characteristic of the user. The user obtains access to one or more high level operational features of the vehicle if the detected biometric characteristic matches that of an authorized user.
