What are the reasons for a car door not opening?

[Theo]

Door not opening reasons are as follows: Temperature effects: Winter temperatures in northern regions are very low. If water accumulated in the car locks, door frames, and handles is not dried after washing the car, it can easily freeze. In the morning, the car door may not open. Some anxious owners might forcefully pull the door, unaware that this can easily damage the car paint and seals, and in extreme cases, even break the door handle. Child lock power failure: To protect children's safety, many vehicles have child locks installed on the rear doors. When the child lock is engaged, the rear door cannot be opened from the inside and can only be opened from the outside handle. If the vehicle happens to lose power at this time, the door cannot be opened from the outside either. Remote control malfunction: The car remote control is one of the most frequently used components by car owners. It can also malfunction, resulting in the door not opening.
