How to Lock a BMW Car Door with the Key?
2 Answers
BMW vehicles now come with an automatic locking system, which allows the car to lock automatically without using the key. The automatic locking system is essentially a keyless entry system. Below is a detailed introduction to the BMW car key: 1. The BMW key generally consists of three function buttons. (1) The first one is an arrow-shaped button: This is the unlock all doors button. (2) The second one is the BMW logo: This is the lock all doors button. (3) The third one is shaped like a car trunk: This is the button to open the trunk. 2. Every BMW key comes with a small door insert key, which can be used to open the door directly. If the car is locked using the full door lock, the key won't open it and will trigger the alarm.
I've always driven BMWs, and locking the doors is quite straightforward: just press the button with the lock icon on the key fob, and the doors lock immediately. For my older 3 Series, the lights flash once as a confirmation that it's locked, which is really convenient. Some newer models like the i series even lock automatically when the key is away from the car, eliminating the need to press the button every time. However, it's important not to overlook details—like when the key fob battery is low, pressing the button might not work, a lesson I learned the hard way. In such cases, you'll need to use the spare mechanical key inside the key fob to lock the doors manually. Regularly checking the key fob's functionality is crucial; test the button response monthly to ensure reliability. Additionally, while the operation is the same across different models, SUVs like the X5 have louder confirmation sounds. Make it a habit to press the button once when exiting the car to maintain good anti-theft awareness.
