Does the BMW 320 automatically lock?

The BMW 320 automatically locks. When the car key is 30 meters away from the vehicle, it will automatically lock. This is a built-in security system in the car. Principle of the automatic locking function: If the car is equipped with this function, the vehicle will automatically lock when the smart key is a certain distance away from the car. The automatic locking function uses distance sensing to automatically lock the vehicle when it is a certain distance away. Keyless entry function: Many cars come with a keyless entry function, which also relies on distance sensing. When you are within a certain distance of the vehicle, pressing the button on the door handle can automatically unlock the car. If combined with keyless start, you don't need to take out the key from getting in the car to ignition.
Over the past decade, I've driven several BMW 320 models and found that they indeed feature an automatic locking function. Generally, when you start the car and reach a speed of around 10-20 km/h, the doors automatically lock, as if there's a protective mechanism. I think this design is excellent as it prevents the doors from being accidentally opened while driving in the city, which could be dangerous. Sometimes, if I forget to lock the doors manually, the car reminds me while driving, but it won't auto-lock after parking unless done manually. You can adjust this function in the vehicle settings menu, such as turning it off or changing the trigger speed. I recommend keeping it enabled for added safety and convenience. Additionally, BMW's system is very reliable, but occasional minor glitches can be checked by ensuring the car key battery has sufficient power.
From the perspective of vehicle electronic systems, the BMW 320 is equipped with an automatic locking function. It operates based on a speed-sensing mechanism, activating the door locking module when the vehicle reaches a preset speed (typically around 20 km/h) to prevent accidental door openings. This feature comes as standard equipment and is available on most models. You can also customize it through the iDrive system on the center console, setting options like locking delay or linking it with other functions such as the seatbelt reminder. Having experimented with these settings, I recommend regular checks to ensure proper operation. If the function fails, it might be due to poor wiring contact or a fuse issue, though such cases are rare. This well-thought-out design in modern BMWs significantly enhances daily driving safety.
