What are the reasons why the left rear car door cannot be opened from the inside?

The reasons why the left rear car door cannot be opened from the inside are as follows: 1. The car or remote key battery is depleted: The receiving sensor or transmitting sensor cannot function properly, so the door naturally cannot be opened. 2. Child lock engaged: As is well known, to protect children's safety, many vehicle rear doors are equipped with child locks. When the child lock is engaged, the rear door cannot be opened from the inside and can only be opened via the exterior handle. 3. High-speed driving: The central locking system automatically engages. Many car owners may not be aware that when the vehicle speed exceeds 10 km/h, the central locking system automatically locks the doors. 4. After washing the car in winter, water was not wiped dry and the door froze: It can return to normal once the temperature rises. Residual water from washing accumulates in the car's handles, locks, door gaps, etc. Overnight freezing temperatures cause the accumulated water to freeze, firmly locking the door shut, making it naturally impossible to open in the morning.
I've encountered a similar issue before. That time when I was driving a friend's car, I found the left rear door couldn't be opened from inside at all. After checking, it turned out the child safety lock was activated. Many car models, especially SUVs or family vehicles, have a small switch or slider hidden on the inner side of rear doors. If accidentally triggered, the door can only be opened from the outside. This is designed to prevent children from opening doors accidentally. If it's not the child lock, it might be a mechanical failure: such as the door handle linkage rod coming off or rusting, the cable breaking, or the lock block getting stuck. Metal parts tend to rust after long-term use. For electronic door locks, control unit damage or fuse burnout is also common. At that time, I first checked the manual to locate the lock, tried gently a few times without success, then went to the repair shop. The mechanic fixed it with simple tool adjustments. I suggest never pulling hard, as it can damage the door panel. Regularly spraying some lubricant during car washes or maintenance can prevent rust and reduce trouble. Safety first—if the door won't open, don't panic, it's best to solve it steadily.
