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.

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.
