There is a function of automatic door locking on many cars after the beginning of the movement. This option is also available on the 3rd generation Ford Focus vehicle, but it is disabled for security reasons.
If you want to turn on automatic door locking after the beginning of the movement on the Ford Focus III, it will be necessary to update the firmware-for this purpose it is best to refer to the official Ford dealer.
With their hands on Ford Focus 3, you can only activate the rear door lock for child safety: just like in other cars, you have to turn the lever on the door itself.
