1. An electronic entry system for an entry object comprising:
- a portable device carried by a user and including a first memory storing first identification information thereof for verifying authorization of vehicle engine starting, and a first communication means provided within a device body for transmitting first identification information in response to a first request transmitted from outside, the first communication means being a first transponder; and
an in-object device for performing a predetermined operation when the first identification information transmitted from the portable device is identical with registered identification information stored in a memory,wherein the portable device further includes an emergency key detachably accommodated and operable mechanically for entering the entry object, the emergency key including a second memory storing second identification information as registration information which is transmitted to the in-object device to indicate an authorized user at the time of registering a portable device, the second identification information being electronic identification information, and a second communication means for transmitting the second identification information in response to a second request from the in-object device, the second communication means being a second transponder,wherein the in-object device includes a processor operably connected to a third communication means, the processor and third communication means being configured to transmit the first request to the portable device from the third communication means so that only the first communication means responds when determining whether the predetermined operation should be performed, and to transmit the second request to the portable device from the third communication means so that only the second communication means responds when determining whether a registration of identification information should be performed,wherein the portable device further includes a first transmitter/receiver means, wherein the first transmitter/receiver means has another memory storing another information for verifying authorization of vehicle door locking/unlockingwherein the third communication means includes a third transponder, andwherein the third transponder transmits the first request at a first frequency and transmits the second request at a second frequency different from the first frequency.

Abstract
An electronic key system for an entry object such as a vehicle is comprised of a portable device and an in-object device. The portable device has a device body and an emergency key detachably accommodated in the device body. The emergency key has a transponder, which is separate from a transponder provided in the device body. The transponder is for verifying the authority of registration of an additional portable device, while the transponder is for verifying the authority of vehicle control. The device body is also capable of detachably accommodating an emergency key which has no transponder.
