Abstract: A key locking device for an immobilizer system may include a rotor casing having an inner space therein, a rotor rotatably coupled to the rotor casing in the inner space thereof and having a first key hole formed in a front end of the rotor, a locking member selectively coupling the rotor, the rotor casing, and the vehicle key according to rotation of the vehicle key, and/or the vehicle key to be inserted into the rotor through the first key hole and having a locking notch, so that when the vehicle key is inserted into the rotor through the first key hole and rotated along the rotor casing, the vehicle key activates the locking member to lock the vehicle key to the rotor through the locking notch of the vehicle key such that the vehicle key is prevented from being released from the rotor.

Abstract: A steering column locking device has an electromagnetic key interlock function that operates a solenoid to prevents a key knob from being undesirably moved to a lock position, as well as a mechanical key interlock function to conduct the key interlock function even when the solenoid malfunctions. The device includes the key knob and a plunger coupled to the key knob, so that when a user manipulates the key knob to start the vehicle, the plunger both moves axially and rotates. A cam shaft is coupled to the plunger, and a return spring is provided between the plunger and the cam shaft to bias the plunger towards the key knob. A stroke restrictor restricts a stroke of the plunger in the axial direction, and a push release functioning mechanism mechanically prevents the plunger from rotating from an accessory position to a lock position when the key interlock function fails.
