Abstract

A vehicle key fob for communicating information between one or more electronic devices, such as a personal or laptop computer, and a wireless-enabled vehicle. In one embodiment, a wired communications link is established between the electronic device and the vehicle key fob over a wired connection, such as a USB cable. A separate wireless communications link is established between a wireless interface located in the vehicle key fob, such as a wireless adapter, and the wireless-enabled vehicle so that information can be sent from the electronic device to the vehicle, and vice-versa, in a secured manner.

Claims

1. A vehicle key fob, comprising:

a protective housing;

a remote keyless entry (RKE) circuit that is at least partially located within the protective housing and initiates RKE functions at the vehicle; and

a communications circuit that is at least partially located within the protective housing and includes a first interface for establishing a first communications link with one or more electronic device(s) and a second interface for establishing a second communications link with the vehicle, wherein the RKE circuit and the communications circuit communicate with the vehicle over different channels.

2. The vehicle key fob of claim 1, wherein the first communications link with the electronic device(s) is a wired communications link and the second communications link with the vehicle is a wireless communications link.

3. The vehicle key fob of claim 2, further comprising a wired communications port that:

i) extends through the protective housing, ii) physically receives a wired connection from the electronic device(s), and iii) is electronically coupled to the first interface.

4. The vehicle key fob of claim 3, wherein the wired communications port is a universal serial bus (USB) port and the first interface is a USB controller.

5. The vehicle key fob of claim 2, further comprising an antenna that:

i) is at least partially located within the protective housing, and ii) is electronically coupled to the second interface.

6. The vehicle key fob of claim 5, wherein the antenna is a short range radio frequency (RF) antenna and the second interface is a Wi-Fi wireless adapter.

7. The vehicle key fob of claim 2, further comprising a memory device that:

i) has one or more electronic file(s) stored thereon, and ii) is electronically coupled to the second interface.

8. The vehicle key fob of claim 7, wherein the electronic file(s) include at least one driver file or application file for use in operating the first or second interface.

9. The vehicle key fob of claim 7, wherein the memory device has preprogrammed security features stored thereon that correspond to security features stored at the vehicle so that the wireless communications link between the vehicle key fob and the vehicle is secured without a user having to enter an encryption key.

10. The vehicle key fob of claim 1, wherein the RKE circuit and the communications circuit are fabricated on the same printed circuit board (PCB).

11. A vehicle key fob, comprising:

a protective housing;

a wired communications port that extends through the protective housing and receives a wired connection from one or more electronic device(s);

an antenna that transmits and receives wireless signals; and

a communications circuit that is at least partially located within the protective housing and includes a first interface that is electronically coupled to the wired communications port for establishing a wired communications link with the electronic device(s), and a second interface that is electronically coupled to the antenna for establishing a wireless communications link and includes a wireless adapter, wherein the first and second interfaces are electronically coupled to one another so that information can be exchanged between the electronic device(s) and the vehicle through the communications circuit.

12. The vehicle key fob of claim 11, wherein the wired communications port is a universal serial bus (USB) port and the first interface is a USB controller.

13. The vehicle key fob of claim 11, wherein the antenna is a radio frequency (RF) antenna and the second interface is a Wi-Fi wireless adapter.

14. The vehicle key fob of claim 11, further comprising a memory device that:

i) is at least partially located within the protective housing, ii) has one or more electronic file(s) stored thereon, and iii) is electronically coupled to the second interface.

15. The vehicle key fob of claim 14, wherein the electronic file(s) include at least one driver file or application file for use in operating the first or second interface.

16. The vehicle key fob of claim 14, wherein the memory device has preprogrammed security features stored thereon that correspond to security features stored at the vehicle so that the wireless communications link between the vehicle key fob and the vehicle is secured without a user having to enter an encryption key.

17. The vehicle key fob of claim 11, wherein the RKE circuit and the communications circuit are fabricated on the same printed circuit board (PCB).

18. A vehicle key fob, comprising:

a protective housing;

a remote keyless entry (RKE) circuit that is at least partially located within the protective housing and initiates RKE functions at the vehicle;

a wired communications port that extends through the protective housing and is designed to receive a wired connection from one or more electronic device(s);

an antenna that sends and receives wireless signals; and

a communications circuit that is at least partially located within the protective housing and includes a first interface, a second interface, and a memory device, wherein;

the first interface is electronically coupled to the wired communications port for establishing a wired communications link with the electronic device(s);

the second interface is electronically coupled to the first interface and the antenna for establishing a wireless communications link with a vehicle, and includes a wireless adapter; and

the memory device is electronically coupled to the second interface and has preprogrammed security features stored thereon that correspond to security features stored at the vehicle.
