Certain Toyota vehicles offer a feature that automatically secures the doors when the driver moves a certain distance from the car with the key fob. As an example, once the driver has exited the vehicle and walks approximately six feet away, the system will engage, and the vehicle will confirm the action, typically with an audible signal and/or flashing lights.
This capability provides enhanced convenience and security. It mitigates the risk of inadvertently leaving a vehicle unlocked, thus deterring potential theft and protecting personal belongings. The feature arose from advancements in vehicle technology and a desire to simplify the user experience by automating a common task that relies on driver memory and attention.
