Does the BMW 320 automatically lock?
2 Answers
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.
