Why can't the car door be opened from the outside after locking, but can be opened from the inside?

[VonWilliam]

The reasons why the car door cannot be opened from the outside after locking but can be opened from the inside are as follows: Child lock is engaged: You can check if the child lock is engaged. The function of the car child lock is to prevent active and unaware children from opening the door during driving when they are seated in the rear, thereby avoiding danger. In this case, the door can only be opened by an adult from the outside after the car is parked. Triggered the safety mechanism: If the rear door of the car cannot be opened from the inside but can be opened from the outside, it is highly likely that the child lock is in effect. This happens when passengers in the rear seat trigger the safety mechanism while getting in or out of the car. Simply reset it to normal. External handle linkage rod fell off: It is also possible that the linkage rod of the external handle fell off. Just reattach it to function normally. Door opening lever cracked: If the slot for the door opening lever on the external handle is cracked, replacing it will solve the problem.
