What to Do When the Car Door Doesn't Lock Automatically?

[MacGarrett]

When the car door doesn't lock automatically, check the following aspects: 1. Automatic locking has speed conditions—verify if the vehicle speed meets the requirements: The automatic speed-sensing lock is an electronic device that automatically presses the lock button on the door when the vehicle reaches a preset speed, preventing accidental door opening. The default setting by manufacturers is usually between 10-20 km/h, making it the most common type of automatic locking system. 2. Check if the automatic locking function is disabled in the car's computer or hidden: Manufacturers often differentiate between low, mid, and high configurations, hiding some features in lower-end models. You may need to enable hidden functions to find and activate the automatic locking feature. 3. Alternative methods for automatic door locking: The lock button automatically engages when shifting to D gear to prevent accidental door opening; pressing the brake pedal while driving can also trigger automatic locking; another option is manual locking.
