Abstract
A steering lock system for an automotive vehicle includes a steering lock actuator, a control rod, a solenoid with a corresponding plunger and a portable transmitter which produces a radio signal indicative of a transmitter self-identifying code. When the transmitter self-identifying code matches a preset reference code, the solenoid is energized to move the plunger so as to release an engagement between the plunger and the control rod. Accordingly, the control rod is free to move to a position where no engagement between the control rod and the steering lock actuator is established, to allow the steering lock actuator to shift to a steering wheel unlocking position from a steering wheel locking position.
