The KLLOQUE 3-in-1 Biometric Door Knob is the ultimate smart home security solution, offering the convenience of fingerprint unlock, the control of app management, and the reliability of traditional keys. Whether you prefer the ease of a thumbprint door knob, the security of app control, or the trustworthiness of backup keys, this smart door lock caters to your needs.

Designed to provide enhanced privacy and convenience, the fingerprint door knob allows you to easily switch between passage, entrance, and privacy modes by simply rotating the smart knob. This makes it the perfect choice for bedroom door locks, allowing you to keep unwanted guests like roommates or children from entering your personal space.

The KLLOQUE smart door lock comes with a dedicated app (detailed in the manual) that enables you to manage fingerprints, view unlocking records, lock/unlock the door, and activate the privacy mode, all from the convenience of your smartphone. Note that the app control is limited to Bluetooth range; if you require Wi-Fi control, a separately purchased gateway is needed.

For hotel and Airbnb owners, this biometric door knob offers the flexibility to grant temporary access to guests and revoke it easily, all from your mobile device. The security design of the door lock blends style and functionality, with the ability to recognize your thumbprint within 0.1 seconds, store up to 20 fingerprints, and feature a 5-second auto-locking feature to ensure your home's safety. Importantly, the fingerprints are stored locally and not uploaded to the cloud, protecting your family's privacy.

The KLLOQUE fingerprint door lock boasts a built-in 400mAh rechargeable battery that takes 3 hours to charge fully and can last up to 12 months on a single charge. The door lock is easy to install with a screwdriver and fits most US doors, though it's recommended to check the dimensions before purchasing. This keyless entry door lock also features a visual power display and a low-battery alarm function. Note that the battery is not removable, and its life may vary depending on the frequency of use.

For optimal performance, when recording fingerprints, it's important to place your clean and dry finger at different angles and positions to ensure a larger area is scanned. The elderly and children may not be able to use their fingerprints as effectively, so it's recommended to keep fingers clean before unlocking. If the smart knob locks you out after several incorrect fingerprint attempts, there are a few methods to exit the security mode, including unlocking via the app, using the backup key, or waiting for 2 minutes. In the event of a dead battery, the door can be opened using an emergency power supply to charge the smart door knob through a USB+Type C port or by utilizing the backup key.
