Fingerprint Door Lock for Keyless Entry

Harfo's innovative door lock delivers unparalleled security and convenience with its cutting-edge technology. After extensive research and development, we have developed a new series of fingerprint locks to meet your needs. Harfo is committed to creating high-quality, high-performance door locks that provide exceptional user experience.

The Harfo fingerprint lock offers an Accurate Fingerprint Recognition system, allowing you to unlock the door with just a simple touch of your finger. The lightning-fast unlocking speed makes it more convenient than using traditional keys. With the One-Touch Unlock feature, your smartphone becomes the key, providing you with full app control for added convenience and security. You can check your lock data anytime, anywhere.

The Smart Function of the Harfo lock enables you to turn on the passage mode, keeping the lock in an unlocked state as per your requirements. The Auto-Lock function ensures that the door is always secured, as it will automatically lock behind you, providing peace of mind.

The Send eKey feature allows you to generate Timed, Permanent, One-time, or Recurring codes for your friends and guests, and you can easily erase them whenever necessary. The lock supports up to 300 users, making it suitable even for office environments.

The Check Unlock Records feature gives you the ability to monitor your lock's activity on your smartphone app, allowing you to stay informed about who has accessed your home. The Keyless locks with the APP function make your home safer and more convenient.

The Anti-Peep Password feature ensures your privacy by allowing you to add random digits before or after the actual passcode to open the door. This added layer of security protects your information.

The Harfo lock is designed with energy efficiency in mind, as it requires only 4 AA batteries (not included) to operate for up to a year, without the need to worry about battery replacement. Rechargeable batteries are not recommended due to their lower voltage.

In case of low battery power, the lock will alert you through display and voice notifications. If the batteries are completely drained, you can use the backup key or a micro USB power bank as a temporary power supply.

The reversible door handle makes the lock suitable for both right-handed and left-handed doors. Simply use the included L-wrench to change the handle direction.

The Harfo door lock is designed to fit the standard U.S. knob hole size (2 1/8" or 54mm) and can accommodate door thicknesses ranging from 1 3/8" (35mm) to 2 3/16" (55mm).

The Harfo fingerprint door lock is the perfect gift for your family or friends, as it will make their lives more convenient and secure, allowing them to experience the benefits of a smart home lifestyle.
