Smart door cylinder with five ways to unlock – fingerprint, code, NFC card, app and mechanical key – so families, holiday rentals and offices can manage access without copying keys. It replaces a standard euro profile cylinder, connects via Bluetooth to the Tuya Smart Life app and keeps a record of every opening.

• Unlocks by semiconductor fingerprint sensor, password, NFC/RFID card, app or mechanical key for quick access for family, tenants and staff.
• Manages permanent, temporary or time-limited codes, fingerprints and cards in the Tuya Smart Life app, with unlock records, via Bluetooth within approx. 10 m.
• Fits doors with a standard euro profile lock, 35–50 mm thick with a 60 mm standard cylinder dimension: uPVC, composite, wooden and narrow-frame aluminium.
• Keeps your existing door handles, while the reversible handle suits left- and right-opening doors.
• Warns when batteries run low and offers emergency access via USB-A to USB-C power, e.g. from a power bank, or mechanical spare keys.

Fitting is a do-it-yourself job: a tool set, screw set and fitting set are included, and video instructions and dimension drawings help you swap the old cylinder yourself. ADC12 aluminium, ABS and an electroplated copper cylinder are built for long service. The lock runs on 3 AAA alkaline batteries, which are not included. Note that emergency charging only works with a USB-A to USB-C cable; USB-C to USB-C cables are not supported. Hand out access instead of spare keys and stay in control of your door.
