Abstract:
Methods and systems for controlling an operational state of a vehicle having a keyless rotary ignition switch and a locking mechanism coupled to the keyless rotary ignition switch are provided. The locking mechanism is disengaged to allow the keyless rotary ignition switch to be rotated from a first position to a second position by a user when an electronic authorization is detected. The locking mechanism is engaged to prevent the keyless rotary ignition switch from being rotated from the first position to the second position by the user when no electronic authorization is detected.
