RFID-mechanical dual-mode entry key
First Claim
1. A key for use with a dual-mode mechanical and a radio frequency identification vehicle entry system, the key comprising:
- a mechanical blade, formed of a first material, capable of being received by a lock cylinder of the vehicle entry system;
a housing, formed of a second material, the housing couple to the mechanical blade;
wherein the mechanical blade extends from the housing and the housing serves as a handle for the blade;
a microantenna having a pair of connectors disposed in the housing;
a first microcircuit having a pair of connectors disposed in the housing, the first microcircuit being selectively and operably connected to the microantenna;
a second microcircuit having a pair of connectors disposed in the key blade housing, the second microcircuit being selectively and operably connected to the micro antenna;
a double pole, double throw switch disposed in the housing, the double pole, double throw switch having at least a first position and a second position;
wherein the double pole, double throw switch selectively switching the pair of connectors of the microantenna between the pair of connectors of the first microcircuit in the first position, and the pair of connectors of the second microcircuit in the second position;
whereby the selective and operable connections offer a closed passive circuit for the radio frequency identification vehicle entry system.

Abstract
The RFID-mechanical dual-mode entry key includes a key blade attached to and extending away from a housing. A double-pole, double-throw (DPDT) switch is disposed on the key blade housing. A microantenna disposed in the housing is connected to the switch. An unlock passive Radio Frequency microcircuit disposed in the key blade housing is operably connected to a first pole of the DPDT switch to activate the unlock passive RF microcircuit when the switch is thrown to the first pole, exclusively connecting the unlock passive RF microcircuit to the microantenna. A lock passive Radio Frequency microcircuit disposed in the key blade housing is operably connected to a second pole of the DPDT switch to activate the lock passive RF microcircuit when the switch is thrown to the second pole, exclusively connecting the lock passive RF microcircuit to the microantenna, The key supports remote/mechanical locking/unlocking of a vehicle door.
