Fingerprint Door Lock Cylinder: Smart Euro Cylinder for Wood, Steel and Aluminum Doors
You don’t need a brand-new door to go keyless. The SK-S1 fingerprint door lock cylinder swaps into a standard euro cylinder position and unlocks five ways — fingerprint, PIN, RFID card, mechanical key and the Tuya or TTLock App.
Fingerprint First, Four More Ways In
The 360° semiconductor fingerprint sensor reads in 0.3 seconds and stores up to 100 users — comfortable for older family members and kids. Add a PIN, an RFID card, the mechanical key or your phone, and every member chooses what suits them.
Built Like a Real Cylinder
Choose from 60 to 100 mm cylinder lengths to match your door, and fit it into wood, steel or aluminum doors 35-45 mm thick. The ANSI Grade 3 body and IP5X dust protection keep the lock dependable through years of daily use.
A Smart Housekeeper, Not Just a Lock
Pair the SK-S1 with the Tuya App for unlock alerts, family-arrival notifications and a hijack alarm — use a special password or fingerprint when forced, and help is silently signaled. Every event is recorded for review.
Where the SK-S1 Works Best
- Home front doors – fingerprint entry for the whole family.
- Apartment and rental units – change PINs between tenants.
- Office and studio doors – control staff access per person.
- Wood, steel and aluminum doors – universal euro cylinder fit.
