What are the reasons why the car door cannot be opened?

[LaAyla]

The reasons why the car door cannot be opened 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 vehicles are equipped with child locks on the rear doors. When the child lock is engaged, the rear door cannot be opened from the inside and can only be opened using 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 will automatically lock the doors. 4. After washing the car in winter, water was not wiped dry, and the door froze: It will return to normal once the temperature rises. Residual water from washing the car accumulates in the door handles, locks, and door gaps. The extreme cold overnight causes the accumulated water to freeze, firmly freezing the door shut, making it naturally impossible to open in the morning.
