Make everyday access to an indoor room simpler with the Smart Fingerprint Door Lock. Choose from fingerprint, passcode, card, mechanical key, or Bluetooth app access rather than relying on a single unlocking method. The supplier lists a reversible handle, making door orientation another detail you can check before installation.
Designed for interior doors, the D6 combines an aluminium-alloy body with a painted finish. It can be considered for a bedroom, office, or storage-room installation when the door preparation matches its requirements. A silent mode is listed, but the supplier does not detail its behavior or sound level.
Before you buy
Door fit: The supplier specifies door thickness of 35–55mm and a 6068 mortise configuration. These details alone do not establish a drop-in replacement for your existing lock. Compare the full installation dimensions, door preparation, and handle clearance before ordering.
Indoor use only: The specification explicitly states interior-door application and no waterproof protection. Do not choose it for a rain-exposed entrance or assume the materials make it outdoor-rated.
Connection and app: Bluetooth connectivity and the Tuya platform are listed. Away-from-home unlocking, direct WiFi connection, compatible gateways, and voice-assistant support are not established by this sheet. Do not assume it provides remote access from anywhere.
Power: Requires four AAA alkaline batteries. Battery inclusion is not stated. The supplier lists a Type-C emergency power interface, not a rechargeable-battery specification; follow the manufacturer's emergency-power instructions.
Access and data: Fingerprint, password, card, mechanical-key, and app unlocking are listed. User capacity, access-log retention, biometric-data storage, sharing practices, and subscription terms are not provided.
Quick questions
Will it fit my current door? Check the 35–55mm thickness range and 6068 mortise specification against a complete dimension drawing. Ask an installer to confirm the required preparation before changing the door.
Can I unlock it while away from home? Not confirmed. The supplied sheet identifies Bluetooth, but does not establish an internet-connected remote-access method or gateway compatibility.
What happens if the batteries run low? The supplier lists mechanical-key access and a Type-C emergency power interface. Keep a backup key accessible and follow the manual for emergency power. Low-battery warnings and battery runtime are not specified here.
Are keys, cards, and batteries included? The sheet lists supported unlocking methods, not package quantities. Confirm the package contents before purchase; support for cards or keys does not establish how many are supplied.
Can I use it on an outside door? No. The supplier specifies interior use and no waterproof protection.
