In northeast China, a video captured a moment when a mother and her son returned home, only to realize they had forgotten their keys.

The video was filmed on January 12, 2024, in Shenyang, Liaoning.

The mother couldn't recall the door lock's code, fearing they might be locked out. However, to their surprise, the child took matters into his own hands and began operating the keypad lock.

The child pressed the buttons for a while, and miraculously, the door swung open.

The mother was puzzled by this dilemma and she published the video on the Chinese Internet. Many netizens offered different codes for her to try but she still failed to open the gate door after a few days of trying.

Unexpectedly, the mother called the staff of the property management company and they told her there was no password set for the door.

The password for the door remains a secret for her.
