The steering lock is never usualy on, I think the ECU detected an introder. I unlock it I simply had to lock and unlock the door with my key and then it allowed me to put the key in the ignition. Before that I could not turn the ignition at all.
Not wanting to sounds offensive, but I think it might have been phycological (sp?). The ECU cannot detect intruders unfortunatly nore does it engauge/disengauge the steering lock.
