The ignition key with a steering
lock is a component which carries out the main function, through
the insertion of a coded mechanical key, of supplying several circuits
including the ignition/injection system, the engine starting and
the services controlled by the ignition.The steering lock function is included amongst
its tasks.The ignition key should be equipped with
an 'anti-repeater' device which prevents the starting manoueuvre
if the key is not returned to the STOP position.The steering lock has two safety devices
so that if one of them is broken and the ignition key is in the
ON position the steering column cannot be mechanically locked.If the parking lights button is pressed
it is possible to move from STOP to PARK and it is automatically
released by turning the key to the STOP position.

The ignition switch is also used
as a support for the aerial needed in transferring the codes in
the ignition key transponder and is used by the FIAT CODE system
for releasing the injection control unit (NCM) and allowing the
engine to be started up.
