SMART LOCK GUIDES / Sep 17, 2026

Ultra-Thin Smart Door Lock Guide: Slim Aluminum WiFi Fingerprint Lock with Tuya App

Ultra-Thin Smart Door Lock: Slim Aluminum Keyless Entry With a 34mm Profile

Traditional locks can be pried, keys get lost, and semi-automatic handles are slow. The SK-X7 ultra-thin smart door lock fixes all three — a slim 34 mm aluminum panel that unlocks with fingerprint, PIN, card, key or the Tuya / TTLock App.

Five Ways to Unlock, Zero Old Problems

Fingerprint, PIN, RFID card, mechanical key or the app — everyone in the household chooses what works. The C-grade cylinder resists prying, and 100 fingerprints cover the whole family plus regular visitors.

Virtual Password Stops Shoulder Surfing

Enter random digits before and after your real PIN — for example virtual 2175 + correct 151574 + virtual 2175. Onlookers can never pick out your actual code.

Design Details That Matter

The 34 mm panel keeps the lock visually quiet on modern doors. A built-in electronic doorbell greets visitors, the USB emergency port rescues a dead battery, and the 3585 mortise is included — install it out of the box.
