What happens when the ignition switch is turned to lock?

When the ignition switch is turned to the "lock" position, it typically disables the electrical systems of the vehicle, preventing it from starting. This position also locks the steering wheel in many vehicles, providing an added security feature to deter theft. Additionally, some vehicles may have features that prevent the key from being removed unless the switch is in the lock position. Overall, it ensures that the vehicle is secure when not in use.
