Frequently Asked Questions
Q: Does the Kingku T12 smart door lock require a Wi-Fi connection to work?

A: The Kingku T12 is designed for doors between 35 mm and 55 mm thick and is compatible with steel, wooden, brass, stainless steel, and most other standard door materials. The reversible handle direction makes it suitable for both left- and right-handed door configurations.
