Semiconductor Fingerprint Recognition: Rejects fake fingerprints (e.g., silicone or paper copies) with a 99.8% accuracy rate, ensuring only authorized users gain entry.
Low Pressure Alarm: Alerts users when battery power is low (below 4.5V DC), preventing unexpected lockouts and maintaining continuous security.
Anti-Lock Function: Protects against tampering (e.g., forced entry attempts or password guessing) by triggering a temporary lockout, enhancing overall safety.
Multiple Unlocking Methods: Offers 6 ways to unlock—fingerprint, password, RFID card, mechanical key, mobile app, and remote control—perfect for situations like lost cards or dead batteries.
Easy Installation: Comes with step-by-step video guides and all necessary hardware, allowing DIY installation in under 30 minutes (no professional tools required).
Mobile App Integration: Enables remote access management (e.g., granting temporary passwords to guests) and real-time activity logs (e.g., tracking who entered and when) via a user-friendly app.
CNC Anodizing Construction: Resists scratches, corrosion, and wear, ensuring the lock maintains its appearance and functionality for over 10 years.
Weather-Resistant Design: Suitable for indoor use in humid or temperature-fluctuating environments (e.g., bathrooms or entryways), with an IP44 dust and water resistance rating.
Homes & Apartments: Secure bedrooms, front doors, or storage rooms. The 100-fingerprint capacity is ideal for families with multiple members, while temporary app passwords can be shared with babysitters or cleaners.
Villas & Townhouses: Pair with Hele Doors’ Villa Doors Series for a cohesive security system, leveraging the lock’s compatibility with thick (up to 85mm) villa doors.
Offices & Coworking Spaces: Manage employee access with 300 password slots, restricting entry to sensitive areas (e.g., server rooms or meeting halls).
Schools & Medical Facilities: Compatible with Hele Doors’ School Door Series and Medical Door Series, providing hygienic access (no need for physical keys) in high-traffic areas.
Shared Spaces: Ideal for Airbnbs, hotels, or gyms, where temporary access (via app or card) can be granted to guests or members without sharing permanent keys.
Prepare Tools: Gather a screwdriver, drill (if needed), and the included mounting kit.
Check Door Compatibility: Ensure your door thickness is 35-85mm; adjust the lock’s backset (60mm or 70mm) to fit your door.
Mount the Lock Body: Attach the main lock body to the door edge, securing it with the provided screws.
Install the Front & Back Panels: Connect the front panel (with fingerprint sensor) and back panel (with keypad) using the included cables.
Test the Lock: Use the mechanical key to test basic functionality, then follow the app guide to set up fingerprint and password access.
Fingerprint Unlocking: Place a registered finger on the sensor (located on the front panel) until you hear a “beep” and the lock tongue retracts.
Password Unlocking: Enter your 4-8 digit password on the back panel keypad; press “#” to confirm.
Mobile App Control: Open the Hele Doors app, select your lock, and tap “Unlock” (requires Bluetooth or Wi-Fi connection). You can also view access logs or share temporary passwords here.
Battery Replacement: When the low-pressure alarm sounds, open the back panel, remove the 4 dry batteries (AA size), and replace with new ones.
Solution: Clean the sensor with a dry cloth (dirt or moisture may affect recognition). If the issue persists, re-register your fingerprint via the app—ensure your finger is fully placed on the sensor during registration.
Solution: Yes! Use the included mechanical key (stored in a safe place) to unlock the door. You can also connect a 5V USB power bank to the emergency port (on the front panel) for temporary power.
Solution: The lock fits most standard doors with a thickness of 35-85mm. If your door has a non-standard backset (distance from the edge to the keyhole), contact Hele Doors customer support for a custom adapter.
