Why does the car door lock as soon as it is closed?
2 Answers
The reasons why the car door locks as soon as it is closed are as follows: The car has the auto-lock function enabled: The car door locks as soon as it is closed because the auto-lock function is enabled. The purpose of the auto-lock function is to prevent theft, allowing the doors to lock quickly after driving, preventing door-pull robberies during traffic jams or at red lights, thus providing a certain level of security. Pros and cons of the auto-lock function: The advantage is that it protects child passengers inside the car, preventing young children from opening the door handle while the car is in motion. The disadvantage is that in case of an accident, it may hinder escape.
I was also quite puzzled when I encountered this issue last time, but later found out it was the door lock sensor acting up. This automatic locking feature was originally designed for anti-theft purposes, but sensor misjudgment can cause this. Listen carefully to the sound when closing the door - if the locking sound is unusually fast, it might be the contact switch getting stuck. For example, that small black rubber pad on the door frame - if it's flattened, it could send false signals. I remember that time I went to a car wash, the high-pressure water jet loosened the wiring harness connector inside the door, causing it to click and lock every time I closed the door. I had to call the locksmith three times. Now I've developed a habit of opening the window before closing the door to avoid locking my keys inside.
