Abstract: A steering lock device and method of manufacturing the steering lock device, which is interoperated with an electronic authentication system via minimal structural changes, whose productivity is improved since coupling/decoupling is simple, and whose security against motor vehicle theft is improved, is provided. In the steering lock device, an actuator is coupled with a cam protrusion being coupled with a lock pin, and thereby moves the lock pin. The actuator is operated by an electronic authentication device being carried by a driver, moves the lock pin when receiving a driving signal, and selectively fixes a steering column. Due to the steering lock device and the method of manufacturing the steering device, productivity is improved since coupling/decoupling is simple, and security against motor vehicle theft is improved.
