BMW vehicles will lock automatically if not locked manually after parking. The car will automatically lock when the key is 30 meters away from the vehicle. This is a built-in security system in the car. Features of BMW's security system: The key has a transmitter. When the distance between the key and the car is less than or equal to the unlocking distance, the car will unlock automatically. Conversely, when the distance exceeds this range, the car will lock. Therefore, there is no need to manually press a button to lock or unlock the car. Pros and cons of BMW's automatic locking feature: Pros: Anti-theft, the car locks quickly after driving, preventing door-pull robberies during traffic jams or at red lights; provides protection for children inside the car, preventing them from opening the doors while the car is moving. Cons: In the event of a collision while driving, passengers may not have time to unlock the doors. In severe accidents, this could also lead to passengers losing consciousness.
