The lock assembly includes a ball nut having one or more rows of lock protrusions extending axially from an external circumference of the ball nut. A lock rotor encircles the ball nut, the lock rotor having a row of ridge protrusions extending axially inward from an internal circumference. In a lock position, the ridge protrusions are arranged between locking protrusions. In an unlocked position, the ridge protrusions are arranged between adjacent locking protrusions.
