Abstract

A remote wireless keyless entry transmitter includes a communications interface for connecting the transmitter directly to an in-vehicle network for registering the transmitter with the vehicle access system. The interface is further connectable to a personal computer to load a set of control codes and programming codes corresponding to a vehicle. The transmitter is programmable to operate multiple functions for multiple vehicles, separately or simultaneously. The transmitter can include a transponder circuit, a display, an accelerometer and a key coupler. A wireless transponder is operationally associated with a vehicle security system by physically connecting the transponder to a vehicle data port with a temporary data link and transferring data between the security system and the transponder over the data link to enable subsequent wireless operation of the security system with the transponder. The transmitter can include an audible signal generator and be programmable to respond to a pager signal.

Claims

1. A programmable remote keyless entry device for controlling a wireless access system of a vehicle, the entry device comprising:

a wireless signal generator for wirelessly transmitting control codes to the access system;

a processor coupled to the signal generator;

memory containing;

programming code configured to place the access system in a programming mode for registering the entry device with the access system;

an identification code identifying the entry device; and

control codes configured to cause the vehicle access system to respond and operate access system features after the entry device is registered with the access system;

a switch coupled to the processor and operable to cause the signal generator to transmit the control codes to the access system; and

a communications interface coupled to the processor and physically connectable to a data port of the vehicle,

wherein the processor is configured to transmit the programming code via the data port while the entry device is unregistered with the access system, thereby placing the access system in a programming mode to register the entry device with the access system to enable subsequent response by the access system to the control codes.

2. The entry device of claim 1, wherein the communications interface is connectable to a personal computer to load the control codes and programming codes onto the entry device.

3. The entry device of claim 1, further comprising a data interface cable configured for wired connection to the data port.

4. The entry device of claim 1, wherein the data port is an OBD diagnostic port.

5. The entry device of claim 1, further comprising an audible signal generator and wherein the processor is configured to register a paging signal, whereby the entry device can be located using a paging signal of another device.

6. The entry device of claim 5, wherein the paging signal is a telephone handset paging signal.

20. The entry device of claim 1, wherein the switch is operable by manipulating a button on the entry device.

7. A method of operationally associating a wireless access device with a security system of a vehicle, the method comprising:

physically connecting the access device to a data port of the vehicle with a data link;

transferring programming codes from the access device to the security system over the data link while the access device is unregistered with the security system, thereby causing the security system to enter a programming mode; and

then

transferring data from the access device to the security system, the data including a transmitter identification code, thereby registering the access device with the vehicle security system to enable subsequent wireless operation of the security system with the access device.

8. The method of claim 7, further comprising, before connecting the access device to the data port of the vehicle, physically connecting the access device to a data port on a personal computer and transferring from the personal computer to the access device a set of control codes selected to correspond with the year, make, and model of the vehicle, thereby configuring the access device for subsequent registration.

9. The method of claim 7, further comprising, before transferring the programming codes over the data link, downloading the programming codes to the access device.

10. The method of claim 7, further comprising downloading vehicle access system control code data onto the access device to configure the access device for use with the vehicle, the control code data including data configured to unlock the vehicle.

17. The method of claim 7, wherein the transmitter identification code is transferred over the data link.

18. The method of claim 7 further comprising, after transferring the data, disconnecting the access device from the data port.

11. A method of operationally associating a keyless access device with a vehicle, the method comprising:

downloading, onto the access device programming code data configured to initiate a programming mode of the vehicle;

downloading onto the access device control code data configured to wirelessly operate access functions of the vehicle after registering the access device with the vehicle;

connecting the access device physically to an in-vehicle network port of the vehicle; and

registering the access device with the vehicle by transferring, while the access device is unregistered with the vehicle, the downloaded programming code data to the vehicle via the network port, thereby initiating a programming mode of the vehicle, and then transmitting an access device identification code from the access device to the vehicle, thereby storing the access device identification code in vehicle memory.

12. The method of claim 11, further comprising connecting the access device to an in-vehicle network of a second vehicle and registering the access device with a vehicle access system of the second vehicle.

13. The method of claim 11, further comprising mapping a vehicle access system feature to a manually operable control of the access device.

14. The method of claim 13, further comprising assigning a hierarchy of vehicle access system features to the control.

15. The method of claim 14, wherein the hierarchy includes prioritization of first and second vehicle access system features.

16. The method of claim 14, further comprising displaying on the access device the hierarchy for selection of features by a user.

19. The method of claim 11, wherein the access device identification code is transmitted to the vehicle in a transmission through a remote keyless entry receiver of the vehicle.

21. A programmable remote keyless entry device for controlling a wireless access system of a vehicle, the entry device comprising:

a wireless signal generator for wirelessly transmitting control codes to the access system;

a processor coupled to the signal generator and configured to cause the signal generator to transmit the control codes from the remote keyless entry device to the access system to operate access system features;

memory containing;

the control codes;

programming code configured to place the access system in a programming mode for registering the entry device with the access system; and

an entry device identification code; and

a communications interface physically connectable to a data port of the vehicle;

wherein the processor is configured to transmit the programming code via the data port with the entry device unregistered with the access system, thereby placing the access system in a programming mode to register the entry device with the access system to enable subsequent response by the access system to the control codes.
