SMART LOCK GUIDES / Sep 15, 2026

Smart Door Lock Buying Guide: Fingerprint, Password, Card and Key Options

Why Upgrade to a Smart Door Lock?

A smart door lock replaces your front-door deadbolt with an electronic lock that opens by fingerprint, password, RFID card, mobile NFC or a mechanical key. The SK-A1 digital fingerprint keypad smart door lock keeps all four traditional methods and adds Tuya WiFi remote control, so you never lose the convenience of a key while gaining phone-based access.

Four Ways to Enter, One Lock

  • Fingerprint – up to 100 fingerprints, recognized in under 1.5 seconds.
  • Password – touch keypad PIN entry, plus temporary passwords for guests and cleaners.
  • RFID card – tap a card for quick access.
  • Mechanical key – an outdoor keyhole for emergencies.

You can also add a smart access card to a compatible NFC phone and tap the lock to open.

Tuya WiFi Remote Control

The WiFi version of the SK-A1 connects directly to your router. Through the Tuya App, you can unlock the door from anywhere, issue time-limited passwords, and check door lock reminders and operation logs on your phone. This is especially useful for rental properties, holiday homes and busy households.

  • USB emergency port – power the lock temporarily if the battery runs out.

Which Finish Fits Your Door?
