Abstract
A key device having a key coil (75a) disposed in a key (75) inserted into a key cylinder (2). Vehicle coils (5a to 5d) which are disposed on a vehicle and to be magnetically coupled with the key coil (75a) perform supply of an electric power and air-propagation communication, thereby reading code information transmitted from the key (75a) . The coils are configured in such a manner that the vehicle coils (5a to 5d) are disposed in the vicinity of a key insertion slot (2a) of the key cylinder (2) so that an induction magnetic field is generated in a substantially upper half portion of the key insertion slot or in a pair of lateral portions on both the sides of the key cylinder.
