What are the reasons for difficulty in opening car doors?

Difficulty in opening car doors can be caused by remote control failure, cold weather in winter preventing opening, or structural faults in the door lock. Below are detailed explanations of these reasons: Remote control failure leading to inability to open: Mainly due to unresponsive buttons, low battery, environmental factors such as strong signal interference or shielding, malfunctioning anti-theft system, or the need for remote control re-matching and encryption. Cold weather in winter causing inability to open: In northern regions, winter temperatures are very low, often below freezing. After washing the car, residual water can accumulate in areas like the door handle, car lock, and door frame gaps. After a night of extreme cold, this water turns into ice, firmly freezing the door shut, making it impossible to open in the morning. Structural faults in the door lock causing inability to open: The likelihood of the door lock itself malfunctioning is very low, mostly occurring in cars around ten years old. Even in high-end vehicles, the working principle is complex and not widely understood, but the door lock structure is relatively simple, typically consisting of a lock cylinder, lock block, central control motor, and operating mechanism. Friction between the vehicle's door handle lock and the lock post can be significant, making it laborious to open and close the door. Prolonged use leads to poor lubrication, resulting in difficulty in opening the door.
I've encountered many situations where car doors are hard to pull open, especially in older vehicles that have been used for years. The most common issue is rusted or unlubricated door hinges causing them to seize up. When those small metal joints accumulate dust or rust, the door becomes as difficult to open as if it were welded shut - gentle pulling won't work and you have to use force. Door lock problems also frequently occur, where a stuck or worn lock cylinder makes the key unable to turn, or when the car body becomes misaligned after minor collisions, causing doors to be hard to open - this is best fixed by an auto repair shop. I've also noticed that aged door seals can swell and stick to the door frame, especially noticeable during rainy or cold weather; silicone lubricant spray can help. Prevention is simple: clean and lubricate the hinges every six months, and avoid using excessive force when pulling doors to prevent damaging other components.
I have a ten-year-old sedan at home, and the door often won't open. I've tried to check the reasons and found that it's usually due to the lock getting stuck or hinges rusting. For example, in winter when there's a lot of dew, the door frame freezes, or insufficient lubrication makes it stick badly. I usually spray some WD-40 on the hinges, wait a while, and try again, which solves the problem most of the time. Another factor could be the deformation and aging of the sealing strip, which gets squeezed when the door is closed, making it hard to open, or the car parked on a slope causing the door to slightly stick due to gravity. Long-term neglect of this issue can lead to faster wear of door components and even safety risks. I suggest wearing gloves and being careful when attempting DIY fixes, and if that doesn't work, seek professional repair. Don't forget the small expense of lubricant during maintenance to avoid bigger problems.
