Description
The Dahen S04 Smart Aluminum Door Lock brings intelligent, app-controlled access to one of the most popular door types in modern construction. Whether it’s a residential entry, balcony door, office, or apartment, the S02 delivers a seamless, keyless experience tailored for aluminum-framed doors.
With five unlocking methods — App Control, Fingerprint, Password, RFID Card, and Mechanical Key — every user can choose the access method they prefer. The integrated Grade C lock cylinder, the highest civilian security rating, offers maximum resistance against picking, drilling, and bumping.
Powered by the Tuya / Smart Life app over WiFi, the S02 puts complete control in the palm of your hand. Generate temporary passwords for guests, review entry logs in real time, and grant or revoke access from anywhere. Crafted from premium aluminum alloy, designed for 35–55 mm door thickness, with the 3585 mortise standard, the S02 installs cleanly on most aluminum doors.
