Does the BMW 3 Series automatically lock the doors?

BMW 3 Series automatically locks the doors. Here are the pros and cons of the auto-locking function: Advantages of auto-locking: It provides protection for passengers with children inside the car, preventing young children from opening the door handles while the vehicle is in motion. Disadvantages of auto-locking: It may hinder escape. The central locking system is a combination of mechanical and electronic devices. In the event of an accident, if the electronic devices fail, passengers can still open the door locks to escape (provided the locks are not damaged). However, if all occupants inside the car are unconscious, rescuers outside may waste more time trying to open the doors, and breaking the glass could also cause injuries.
I've driven several BMW 3 Series models and found that most modern versions do indeed have the auto-lock doors feature. It's quite thoughtful—for example, when you reach a certain speed, usually between 15 to 20 km/h, the doors automatically lock to prevent accidental opening or theft in traffic. However, keep in mind that it may not be enabled by default; you'll need to set it up in the iDrive menu—go to Vehicle Settings, select Central Locking System, and then enable Speed-Dependent Auto-Locking. The doors will also auto-lock if the key is left at a distance from the car, though be aware that this might not work if the key battery is depleted. I missed this setting when driving an older 3 Series and had an awkward moment once, which was later resolved at the dealership. Overall, this feature enhances both safety and convenience, and I recommend new owners explore more personalized settings.
