1. An electronic key system comprising:
- a transmitter that transmits the interrogational signal to a mobile unit;
a receiver that receives a code signal transmitted from the mobile unit in response to the interrogational signal;
a controller that checks a relation between the code signal and a memorized signal, and controls a state of a door of a vehicle based on a check result of the relation;
an indicator that is disposed on the vehicle to indicate the state of the door; and
a detection means for detecting an opening operation of the door that is operated by a user having the mobile unit,wherein the controller sets the door of the vehicle in an unlock-standby state when the code signal transmitted from the mobile unit is authenticated when the user having the mobile unit approaches the vehicle, and unlocks the door when the opening operation of the door is detected by the detection means in the unlock-standby state, andthe indicator starts to indicate the unlock-standby state of the door in a certain indication mode when the door becomes in the unlock-standby state, and the indicator changes the indication mode when the door is unlocked.

7. An electrical key system for a vehicle that has a first door and a second door, comprising:
-
a transmitter that transmits an interrogational signal to a mobile unit; a receiver that receives a code signal that is transmitted from the mobile unit in response to the interrogational signal; verification means for verifying the code signal against a memorized signal; determination means for determining whether the mobile unit exists near the first door or near the second door when verification means verifies the code signal; control means for controlling states of the first door and the second door based on the verification of the verification means and the determination of the determination means; a first indicator that indicates the state of the first door; a second indicator that indicates the state of the second door; and a detection means for detecting an opening operation of at least one of the first door and the second door that is operated by a user having the mobile unit, wherein the control means sets the at least one of the first door and the second door in an unlock-standby state when the code signal transmitted from the mobile unit is authenticated when the user having the mobile unit approaches the vehicle, and unlocks the at least one of the first door and the second door when the opening operation of the at least one of the first door and the second door is detected by the detection means in the unlock-standby state, wherein the indicator starts to indicate the unlock-standby state of the at least one of the first door and the second door in a certain indication mode when the at least one of the first door and the second door becomes in the unlock-standby state, and the indicator changes the indication mode when the at least one of the first door and the second door is unlocked, wherein the control means controls the first indicator and the second indicator so that the first indicator and the second indicator indicate in different modes when the state of the first door is different from the state of the second door. - View Dependent Claims (8, 9)
