How to Lock the Doors of a BMW?

[MorganFitz]

Some BMW models come with an automatic door locking feature, which can be activated in the iDrive system to automatically lock the doors while driving. Alternatively, you can use the smart key to lock the doors after parking. Below is an introduction to the automatic door locking function: 1. When the vehicle reaches a preset speed, the door lock buttons will automatically engage to prevent accidental opening of the doors. The preset speed is usually set by the manufacturer, typically between 10-20 km/h. 2. This function can be used for anti-theft purposes, as the doors lock shortly after driving begins, preventing potential theft during traffic jams or at red lights. 3. It also provides protection for children inside the vehicle by preventing them from opening the doors while the car is in motion.
