Abstract

A key body (14) is inserted into a recess (16) to be held on a card key support (12). When a spare key (10) is used, the key body (14) is removed from the recess (16) and inserted into the recess (26). Accordingly, a lock insertion portion (14B) protrudes from the card key support (12) for manipulation of the key. A transmitter element (18) is mounted to the card key support (12) near a base portion (14A) of the key body (14) which is mounted to the recess (26) so that an ID signal is transmitted from the transmitter element (18) in the direction of the key cylinder in the same manner as in an original key. An operating condition of an engine is thereby maintained.
