Abstract: A method for unlocking a steering system that includes detecting and validating an identity input. After the identity input is validated a vehicle start command is detected and thereafter a steering assist mechanism is enabled. Once the steering assist mechanism is enabled, a force is applied to a steering column utilizing the steering assist mechanism.
