Fingerprint unlocking is a suitable authentication method for families of all ages, from children to elderly people who are not familiar with digital passwords. This feature provides a simple and fast way to access the door. Families with children and elderly can use the app to monitor the door lock status and remotely open the door to ensure family safety.

Key unlocking is a practical and reliable choice for elderly people with unclear fingerprints or reduced memory. The smart door lock offers three convenient unlocking methods: fingerprint unlock, app unlock, and key unlock, meeting people's daily needs in multiple scenarios, including bedrooms, living rooms, closets, and apartments.

The fingerprint unlock technology uses biometric identification, with a recognition rate of up to 99.8%. It can accurately identify your fingerprint and unlock the door in just 0.3 seconds, securely accommodating up to 50 fingerprints to ensure seamless access for multiple authorized individuals.

The auto-lock feature ensures your home's security even when you're in a hurry. The smart knob will automatically lock after the door is closed, with a default locking time of 5 seconds. You can also set the locking time from 5 to 60 seconds in the app.

The privacy mode allows you to have a private space, where only the admin fingerprint and keys can unlock the door from the outside. This feature ensures that you are not disturbed by others.

The passage mode, on the other hand, allows you to get in and out freely, as the door knob will not be locked automatically when you close the door.

The installation process is straightforward, with detailed instructions and videos provided. You can complete the installation with just a screwdriver within minutes. Please note that this smart lock requires 4 AAA alkaline batteries, which can last for up to one year.

We offer a replace-new service for damaged items (non-human-caused damage), ensuring hassle-free post-purchase support. If you have any problems with our product, please send a message to our customer service team, and we will be here to help you solve any issues.

The smart door lock is compatible with both iOS (iOS 7.0 and above) and Android (Android 4.3 and above) systems, allowing you to use the app for various features, such as managing records and remotely unlocking the door. Additionally, all operations can be completed independently on the door handle, even without the app.

In summary, this smart door lock offers a convenient and secure solution for families of all ages, with multiple unlocking methods, automatic locking, privacy features, and easy installation. We are committed to providing professional service and support to ensure a hassle-free experience for our customers.
