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

[McRylee]

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.
