The reason why the driver's door cannot be opened is that the lock in the driver's position is faulty, and it needs to be dealt with at a 4S shop in time. Reasons why the driver's door cannot be opened after unlocking: You can enter the car to check whether the unlock button on the driver's door is in the unlock position. If not, it means the lock cylinder is damaged. At this time, you can only go to a 4S shop or repair shop to replace the lock cylinder. When closing the door, you should try to avoid slamming it hard, as forceful closing can easily cause internal breakage of the lock cylinder, seriously affecting its service life. Secondly, you should regularly add a certain amount of lubricating oil to the lock cylinder, otherwise, in humid areas, the lock cylinder can easily rust and become stuck, making the door impossible to open. Car door lock maintenance tips: Car door locks should not be exposed to rainwater, as this can easily cause the small springs inside to rust, making them less flexible during use. The car key is best placed separately and not together with other keys to prevent excessive weight from wearing out the lock cylinder. If you find the key difficult to use or stiff, you can spray some lubricating oil, except for the pin tumbler lock cylinder. If you find the door lock difficult to switch, you can spray some lubricating oil on the latch.
I often find that the driver's door won't open, with the most common cause being a malfunction in the door lock mechanism. For example, if the remote key's battery is dead, pressing the button yields no response at all, and you'll need to try replacing it with a new battery. Sometimes, the door lock gets stuck or rusts internally, especially in humid environments, making the door handle feel jammed when pulled. This could be due to a dirty lock cylinder or insufficient lubrication. Another factor is loose door hinges or latches, preventing the door from aligning properly. Once, I had items in my car that pressed against the door gap, making it impossible to open. In summary, when encountering such issues, first try replacing the battery or manually unlocking the door. If that doesn't work, check if the lock mechanism needs cleaning and lubrication, and it's best to perform regular maintenance on the door locks.
The main driver's door not opening is usually caused by mechanical issues. The door handle itself may be worn out or damaged, failing to connect with the internal locking mechanism when pulled. Alternatively, the lock cylinder could be rusted or clogged, with accumulated dust causing the entire system to seize up. I recommend checking the condition of the door lock components and applying lubricant regularly to prevent rust. If the remote control still works but the door won't open, it might be due to a loose wiring connection interrupting signal transmission. Pay attention to the sound and feel of the door during normal use—any signs of stiffness should be addressed promptly to avoid higher repair costs later.
