Multistage vehicle security system
First Claim
1. A multistage security system for a vehicle, comprising:
- a transceiver which receives a first signal sent from a transponder;
a controller which processes the first signal and activates low level operational features of the vehicle 1f the controller determines that the first signal is associated with an authorized transponder;
an entry sensor which detects the physical presence of a user, the transponder transmiting a second signal to the transceiver when the presence of the user is detected, the controller processing the second signal and activating midlevel operational features of the vehicle if the second signal is associated with the authorized transponder; and
a sensor which detects a biometric characteristic of the user, the user obtaining access to one or more high level operational features of the vehicle if the detected biometric characteristic matches the biometric characteristic of an authorized user.

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.

11. A method of authorizing user access to a vehicle, comprising:
-
activating a transponder to send a first signal to a transceiver residing in the vehicle;
activating low level operational features of the vehicle if the first signal is associated with an authorized transponder;
detecting the physical presence of the user;
transmitting a second signal from the transponder to the transceiver if the presence of the user is detected;
allowing access to the interior of the vehicle if the second signal is associated with the authorized transponder;
after the user enters the vehicle, sensing one or more biometric characteristics of the user;
comparing the sensed biometric characteristic with a stored biometric characteristic; and
enabling access to one or more high level operational features of the vehicle if the biometric characteristic matches with the stored biometric characteristic. - View Dependent Claims (12, 13, 14, 15, 16, 17)
