Embodiments receive information indicative of a certification of a mechanic performing a service on a vehicle, and responsively determine whether the certification is validated. If validated, service on the vehicle by the mechanic is facilitated by placing the vehicle in a service state and generates a signal that causes an unlocking of a vehicle door, hood, or trunk. If not validated, service on the vehicle is inhibited by disabling a vehicle electrical sub-system and generating a signal that causes a locking of the vehicle door, hood, or trunk, wherein a vehicle owner authorization of the mechanic may supersede and facilitate service by instead placing the vehicle in a service state for executing diagnostic software and generating a signal that causes unlocking of the vehicle door, hood, or trunk.
