2nd November 2022 – (Hong Kong) Recently, a male netizen shared on social media that he bought an electronic door lock on Taobao and replaced the metal gate lock of his public housing flat by himself. He commended on the simple installation process. However, some netizens are puzzled that public housing estates usually have regulations and restrictions, and they were surprised that the electronic locks could be installed.

The netizen purchased the “DIY fingerprint lock” that could fit into the existing lock cylinder. He only removed the metal panel to install the lock. The netizen then showed off the lock by tapping a small card to unlock the door, which seems very convenient. The current price of the door lock ranges from 300 yuan to 666 yuan.
