Product Overview

The 52HZ Fingerprint Door Lock is a modern, keyless entry smart deadbolt designed to enhance both convenience and security at your front door. Built by 52HZ, a brand founded in 2020 with a philosophy centered on innovation and optimism, this lock integrates advanced biometric and digital access methods to provide a seamless experience for homeowners who value both practicality and peace of mind. Featuring voice guidance, customizable auto-lock settings, and multiple unlocking options—including fingerprint, access code, and mechanical keys—this electronic deadbolt is engineered for everyday use without compromising safety. Its sleek black finish ensures it complements a wide range of home exteriors, while the upgraded 180° design improves functionality and user interaction.

Key Features

• Built-in Voice Navigation Function: The lock offers real-time voice prompts that guide users through setup, unlocking, and troubleshooting processes, making it accessible even in low-light conditions or for those less tech-savvy. This feature enhances usability by providing clear, audible confirmation of actions such as successful entry or low battery alerts.
• Upgraded 180° Design: With an improved internal mechanism, this deadbolt operates smoothly and reliably, reducing wear over time and ensuring consistent performance across repeated daily use.
• 3-in-1 Keyless Entry System: Users can unlock the door using one of three convenient methods: a backlit keypad for entering a personalized access code, scanning a registered fingerprint via the built-in sensor, or using the included two mechanical keys as a backup. This flexibility ensures access is always available regardless of technology status or user preference.
• Auto Lock & One-Touch Locking: The lock can be configured to automatically engage after a custom delay between 5 and 60 seconds once the door closes, helping prevent accidental left-open doors. Alternatively, pressing the “lock” button for three seconds manually triggers immediate locking—ideal during quick departures when you don’t have time to double-check.
• Anti-Peeping Password Technology: To protect against shoulder surfing or visual observation, the system allows users to add random numbers before or after the correct password sequence. This spoofing technique ensures unauthorized individuals cannot discern the true code from nearby glances.
• Anti-Lock Function: Located on the interior side of the lock, this safety feature prevents external tampering by disabling mechanical operation from outside if needed, granting occupants full control over their privacy and security.
• Low Battery Alert & Privacy Mode: Integrated sensors monitor power levels and notify users when batteries require replacement, minimizing the risk of being locked out unexpectedly. Privacy mode further enhances discretion by silencing audible feedback during sensitive moments.

Designed for standard deadbolt installations, it fits most residential exterior doors commonly found on homes today.

Important Notes

The package includes one electronic deadbolt unit, mounting hardware, two backup mechanical keys, and installation instructions. Professional installation is recommended due to the complexity of wiring and alignment required during setup; however, DIY installation may be possible with basic tools and careful attention to instructions. Compatibility should be verified with existing door thickness and strike plate dimensions prior to purchase. Always replace batteries promptly when the alert sounds to maintain optimal functionality and prevent unexpected lockouts. Note that while the lock supports extensive customization of codes and fingerprints, each user must register credentials through the physical interface—there is no companion mobile app mentioned in the specifications provided.
