6 . The device as defined in claim 4 , wherein said instructions cause said processor to detect said door lock or said door unlock command by interpreting signals from said driver's device received over said wireless interface.
7 . The device as defined in claim 1 , wherein said determination whether said driver's device is located inside or outside said vehicle comprises determining from a signal strength of said driver's device as measured by said wireless interface whether said driver's device is located inside or outside said vehicle.
8 . The device as defined in claim 7 , further comprising a wireless relay separated from said wireless interface, said wireless relay for location in the vehicle and configured to measure said signal strength and to relay said signal strength to said wireless interface.
9 . The device as defined in claim 1 , further comprising an RFID reader module for mounting near a window of said vehicle and having a battery and a transmitter for transmitting to said wireless interface RFID data, said executable instructions causing said processor to determine if said driver is authorized to use said vehicle based on said RFID data, and if said driver is not authorized, to notify a system administrator of a non-authorized attempt and erase the lock/unlock code to prevent further non-authorized attempts to use the device.
10 . The device as defined in claim 1 , wherein the processor is further configured to collect and store location data of a user device during car locking or parking, collect and store location data of a user device upon a request to unlock or start the vehicle, compare the two locations, and only allow the unlocking or starting the vehicle operation if the two locations are significantly the same.
11 . A method for sharing a vehicle having a passive keyless entry and start (PKES) system, said PKES system configured to send challenge messages to a key fob of the vehicle from internal and external antennas, to receive and process response messages from the key fob of the vehicle to authenticate the key fob and to determine if the key fob is inside or outside of the vehicle, the method comprising:
