Abstract

An original generator generates a sequence of access values that are stored into a longer range communication device. A short range communication device, which can be the original generator, uses short range communication during a programming process to transmit an identification number to enable subsequence access from the longer range communication device using the sequence of access values.

Claims

1. A method performed by a service provider comprising:

actuating one or more functions of an original code generator to generate a series of access values referenced by an access index, each actuation causing the access index to change, the series of access values being a subset of a larger series of valid access values;

disabling one or more functions on the original code generator;

labeling the original code generator with a unique label;

setting an access index of the original code generator reference a preceding access value;

hosting a communication system configured to, upon receiving the unique label as an input, download the series of access values onto a longer range communication device, the longer range communication device comprising a long range antenna;

providing one or more remote access devices to each end user of a plurality of end users, wherein each remote access device is a longer range communication device;

providing the original generator device to subsequent end users of the plurality of end users; and

instructing each end user of the plurality of end users to;

download the series of access values onto the end user'"'"'s remote access device;

program an access system of a vehicle to subsequently allow the end user'"'"'s remote access device to use longer range communication to control one or more functions of the vehicle, wherein programming comprises;

initiating a programming mode of the vehicle;

presenting the original generator an immobilizer of the access system;

communicating, via short range communication, the identification value and the access index from the original generator to the access system;

retain the remote access device; and

send away the original generator.

2. A method for operating a short range communication device comprising:

saving a series of access values generated from a short range communication device, the series of access value being a subset of an entire set of valid access values for an access system;

disabling one or more long range functionalities of the short range communication device;

labeling the original communication device with a unique label to identify that the series of access values originated from the short range communication device with the unique label; and

sending the short range communication device to a plurality of users to pair longer range communication devices of the users by communicating, through a short range antenna, an identification value to access systems of the users.

3. The method of claim 2, wherein communicating through the short range antenna comprises communicating to an immobilizer device of the access systems.

4. The method of claim 2, further comprising:

setting an access index into the short range communication device; and

configuring the original communication device to communicate, during a programming process, the access index to the access systems;

wherein the access index references a first access value that precedes other values from the of the series of access values.

5. The method of claim 4,

wherein communicating to a first access system of the plurality of access systems enables a first remote access device to subsequently remotely control functions of a vehicle when the first remote access device transmits, via a first longer range antenna, a first value from the series of access values to the first access system;

and

wherein communicating to a second access system of the plurality of access systems enables a second remote access device to operate with the second access system when the second remote access device transmits, via a second longer range antenna, the first value from the series of access values to the second access system.

6. The method of claim 2, wherein disabling one or more long range functionalities comprises at least one of:

opening a circuit;

shorting a circuit;

covering a button;

disabling a button;

or

programming code to preserve the access index.

7. A system for pairing remote access devices with access systems, comprising:

a plurality of remote access devices, each remote access device comprising a longer range;

a short range communication device comprising;

a microcontroller unit identified by a certain identification value;

memory configured to store an access index;

a shorter range antenna; and

a unique label;

wherein the short range communication device is configured to communicate, using the shorter range antenna, to certain access system to enable subsequent access to the certain access system by a certain remote access device of the plurality of remote access devices via a longer range antenna.

8. The system of claim 7, wherein the certain remote access device stores a certain sequence of access values in a memory, the certain sequence of access values being a subset of access values generated by the short range communication with the microcontroller unit associated with the certain identification value.

9. The system of claim 7, further comprising:

a plurality of short range communication devices, each short range communication device comprising;

a microcontroller unit associated with an identification value different from other microcontrollers of other short range communication devices;

a memory configured to store an access index;

a shorter range antenna;

a label different from labels of other short range devices;

a communication system configured to stores an unique access sequence for each one of the plurality of short range communication devices with a different label.

10. The system of claim 9, wherein the communication system is configured to store an access number as the access index of the selected remote access device.

11. The system of claim 7, further comprising a control unit physically coupled an access system through an on-board port;

wherein the remote access devices are at least one of;

a phone;

a tablet;

a laptop;

each remote access device is configured to download, from a communication system, an application to communicate with the control unit to operate the vehicle access system.

12. The system of claim 7, wherein the short range communication device further comprises a protective design disabling the access index from changing, the protective design comprising at least one of:

opening a circuit;

shorting a circuit;

covering a button;

disabling a button;

or

programming code to preserve the index.

13. The system of claim 7, wherein the short range communication device is configured to communicate, using the shorter range antenna, to an immobilizer of the certain access system.

14. A short range communication device comprising:

a short range antenna configured for wireless communication; and

a microcontroller unit identifiable by an identification value;

wherein communication device is configured to communicate, using the short range antenna, the device identification value with an immobilizer of a vehicle to enable access to the vehicle from a separate remote access device via a longer range antenna.
