A start control apparatus has a steering lock mechanism, which includes a
lock pin and a lock control unit. The lock pin is selectively engaged and
disengaged from the steering shaft. The lock control unit controls the
lock pin. The start control apparatus further includes a portable
communication device, a verification control unit, which communicates
with the portable communication device, a power source control unit,
which control power supply, an engine control unit, which controls the
engine, a lock state detecting switch, which detects an engaged state and
a disengaged state of the lock pin. The lock control unit and the power
source control unit monitor detection signals from the lock state
detecting switch. The engine is permitted to be started on condition that
the control units acknowledge that the lock bar is in the disengaged
state.
