What are the reasons why Volkswagen car doors cannot be locked?

If you are using a remote key to lock the door, it is likely that the remote lock is malfunctioning or the antenna of the car's remote transmitter has aged, causing the remote key to not work. In this case, you can use the spare mechanical key to lock the door. Another possibility is that there is strong magnetic signal interference around the car. Since smart keys use low-intensity radio waves, they cannot function properly under magnetic interference. Below is an introduction to car doors: 1. Car door: A car door provides access for the driver and passengers and isolates external interference, reducing side impacts to some extent and protecting the occupants. The aesthetics of the car are also related to the design of the door. 2. Door quality: The quality of a car door is mainly reflected in its anti-collision performance, sealing performance, ease of opening and closing, and other functional indicators. Anti-collision performance is particularly important because, in the event of a side collision, the buffer distance is very short, making it easy for passengers inside the car to be injured. A good car door will have at least two anti-collision beams, and these beams are relatively heavy. This means that a good door is indeed heavier, but it does not necessarily mean that the heavier the door, the better.
I've encountered the issue of Volkswagen car doors not locking several times myself. I remember one instance when the door wouldn't lock, and I found out it was because the remote key battery was nearly dead—the signal was weak. Replacing the battery solved the problem. Other times, the door wasn't fully closed, perhaps because something like a window or debris was in the way; the door needed to be shut firmly to lock. In winter, freezing can also be an issue, with the lock hole freezing up—using a hairdryer to thaw it usually works. If it's an electrical system problem, such as a faulty door control module or a short circuit, or if a fuse in the car has blown, the lock might fail. Long-term neglect can lead to rust or wear in the locking mechanism, especially in older cars. My advice is to start with simple checks: try locking the door manually with the key, ensure the door is fully closed, and test the remote's battery. If there's no improvement, it's best to take the car to a repair shop to check the circuits and modules—safety first.
