Keyless entry control apparatus
First Claim
1. A keyless entry control apparatus comprising:
- a keyless entry unit storing a plurality of ID codes and provided with ID checking means for checking as to whether an ID code transmitted from a transmitter, which instructs a door to be locked and unlocked, agrees with a previously stored ID code, and ID entry means for, when the transmitted ID code is not stored in the keyless entry unit, storing the transmitted ID code therein; and
a fault diagnosis unit for at least diagnosing faults of said keyless entry unit, said fault diagnosis unit being provided separately from a car and transmitting an entry instruction signal to the keyless entry unit instructing the keyless entry unit to enter an ID code entry mode, wherein;
said ID entry means permits storing of the transmitted ID code transmitted from the transmitter when the entry instruction signal is received.

Abstract
In a keyless entry control apparatus having a fault diagnosis unit provided separately from a car and a keyless entry C/U, the fault diagnosis unit transmits a signal to each control unit connected to a communication line, and when receiving a communication enabling signal transmitted from the keyless entry C/U, the fault diagnosis unit can communicate with the keyless entry C/U. In the case where ID codes are entered in the keyless entry C/U, a signal for setting the keyless entry C/U to ID entry mode is transmitted from the fault diagnosis unit to the keyless entry C/U. The keyless entry C/U which received the signal is set to ID entry mode, and transmits entry information of the ID codes entered in an EEPROM to the fault diagnosis unit immediately. The entry information is displayed on a display device of the fault diagnosis unit.

9. A keyless entry control system, comprising:
-
a transmitter for transmitting an ID code peculiar thereto; a receiver for receiving said ID code transmitted by said transmitter; a memory for storing at least one ID code; a door lock controller connected to both said receiver and said memory, said door lock controller locking and unlocking a door when said ID code received by the receiver is identical with the stored at least one ID code; and an ID code entry controller detachably connected to said door lock controller, said ID code entry controller transmitting an instruction signal when said ID code entry controller is connected to said door lock controller, said door lock controller storing a new ID code transmitted from said transmitter in said memory in response to receiving said instruction signal from said ID code entry controller. - View Dependent Claims (10, 11, 12, 13)

14. A method for controlling keyless entry, comprising the steps of:
-
transmitting an ID code peculiar to a transmitter to a receiver; receiving said ID code transmitted by said transmitter; comparing said ID code received by said receiver with a stored ID code; controlling locking or unlocking of a door by a door lock controller when said received ID code is identical to the stored ID code; transmitting an instruction signal from a diagnosis unit when said diagnosis unit is connected to said door lock controller instructing said door lock controller to enter a mode for storing a new ID code transmitted by said transmitter; and storing the transmitted new ID code in said door lock controller when said door lock controller receives said instruction signal from said diagnosis unit. - View Dependent Claims (15, 16, 17)
