Abstract

A keyless entry device includes: a transmitter which includes an operating section relating to a door lock state for transmitting a door operation information and a specific identifying information based on an operating state of the operating section; and a receiving unit for outputting a signal to a door lock device based on the transmitted door operation information when the specific identifying information transmitted coincides with a registered identifying information stored previously; wherein a plurality of pieces of partial informations obtained by dividing the registered identifying information are sequentially received by the receiving unit to permit the information to be stored in the receiving unit.

Claims

1. A keyless entry device comprising:

a transmitter with an operating section relating to a door lock state for transmitting a door operation information and a specific identifying information based on an operating state of the operating section;

a receiving unit for outputting a signal to a door lock device based on transmitted door operation information when the specific identifying information transmitted coincides with registered identifying information stored previously; and

an operating switch installed in a vehicle and connected to the receiving unit;

wherein the registered identifying information is stored in the receiving unit based on an operating state of the operating switch, and

wherein the operating switch is installed in the vehicle for operating a door to enter a locked state or an unlocked state, and when the registered identifying information is stored by an operation on the operating switch, an output of a control signal for controlling the door lock device to enter the locked state or the unlocked state in conjunction with the operating switch is stopped.

2. The keyless entry device according to claim 1, wherein each of the specific identifying information and the registered identifying information includes a number information relating to a number comprising a plurality of digits, and by operating the operating switch with respect to each digit of the number, the registered identifying information to be stored in the receiving unit is decided.

3. The keyless entry device according to claim 2, wherein the operating switch uses a button system and a figure of each digit of the number information is decided on the basis of a number of times of pressing the operating switch.

4. The keyless entry device according to claim 2, wherein the operating switch uses a button system and a figure of each digit of the number information is decided on the basis of a time period of holding on the operating switch.

5. The keyless entry device according to claim 2, wherein the operating switch comprises a digital figure designating switch for designating a figure of each digit of the number information and a digital figure deciding switch for deciding the figure designated by the digital figure designating switch.

6. The keyless entry device according to claim 2, further comprising a reporting section for reporting that a reception of the each digit of the number by the receiving unit is completed.

7. The keyless entry device according to claim 6, wherein said reporting section is an answerback buzzer.

8. The keyless entry device according to claim 6, wherein said reporting section is an answerback lamp.

9. The keyless entry device according to claim 8, wherein said answerback lamp is a room lamp of the vehicle.

10. The keyless entry device according to claim 1, wherein the registered identifying information is stored in the receiving unit based on the operating state of the operating switch and based on a registered identification signal transmitted from a failure diagnosing device provided separately of the vehicle and diagnoses failures of the receiving unit.

11. The keyless entry device according to claim 1, wherein the receiving unit is so structured that storing the registered identifying information is permitted when a predetermined registration permission signal is inputted.

12. The keyless entry device according to claim 1, further comprising a displaying section for displaying the number information when the registered identifying information is stored in the receiving unit.

13. The keyless entry device according to claim 1, wherein when the registered identifying information is stored in the receiving unit, a customized information is stored along with the registered identifying information.

14. The keyless entry device according to claim 13, wherein said customized information is an information of an answerback function of a door lock.

15. The keyless entry device according to claim 14, wherein said customized information is an answerback pattern number to specify an answerback pattern among several kinds of answerback patterns.

16. The keyless entry device according to claim 14, wherein said customized information is an information to operate an answerback buzzer.

17. The keyless entry device according to claim 14, wherein said customized information is an information to operate an answerback lamp.

18. The keyless entry device according to claim 17, wherein said answerback lamp is a room lamp of the vehicle.

19. The keyless entry device according to claim 1, wherein;

said specific identifying information includes a number information relating to a number comprising a plurality of digits.

20. The keyless entry device according to claim 1, wherein;

said registered identifying information includes a number information relating to a number comprising a plurality of digits.
