The new WELOCK U71 Smart Lock Cylinder delivers a major upgrade to front-door security without requiring a full lock replacement. It gives homeowners advanced biometric access control in a compact cylinder design that installs in just a minute.
WELOCK is a global pioneer in smart lock and biometric security systems, recognized as the first innovator to integrate advanced fingerprint recognition into lock cylinders.
With its modern safety features and remote-ready functionality, the U71 is designed for people who want a stronger defense against break-ins and greater convenience for everyday entry.
Top Advantages
- Easy Setup: DIY installation in 1 minute. Fits almost all standard doors.
- High Security: Bank-grade anti-theft cylinder and encrypted data.
- Multiple Access: Fingerprint, passcode, and app unlock methods.
- Long Power: 1-year battery life with emergency USB charge port.
The U71 removes the complications typically associated with smart home upgrades. Homeowners simply replace their door’s existing Euro-profile cylinder and immediately gain modern security enhancements.
No wiring, drilling, or professional assistance is required, making this an ideal option for renters and older properties.
Security is also significantly increased. The hardened cylinder structure resists forced entry, while encrypted digital access prevents unauthorized duplication or hacking of data. This combination provides both physical and digital protection in one small device.
Convenience plays an equally significant role in its benefits. Having three primary unlock methods ensures flexibility for different situations, whether your hands are full, you forgot your phone, or someone needs temporary entry.
The long-lasting power system further boosts reliability, with an emergency port available if the batteries are ever depleted.
Key Functions
- Fast Fingerprint: Unlocks in 0.5 seconds (stores 20 prints).
- Safe Passcode: Virtual Code feature hides your real password.
- App Control: History logs, temporary codes, and user management.
- Backup Key: Classic mechanical key for emergencies.
- Power Alert: Low-battery warning system.
- Adjustable: Flexible cylinder length for multiple door sizes.
The fingerprint reader is engineered to recognize users rapidly and accurately, reducing fumbling at the door and eliminating the need to stash or duplicate keys. With space for up to 20 prints, every resident can have secure hands-free access.
For passcodes, the Virtual Code system lets users insert random digits before or after their real password to shield it from anyone attempting to observe it. This makes code-based entry far more secure than traditional PIN systems seen on most smart locks.
For those who enjoy connected convenience, the mobile app extends control beyond physical proximity. Users can issue one-time or temporary codes for deliveries or visiting guests, and review unlock history whenever needed.
In urgent scenarios, the included mechanical keys ensure homeowners always have a backup option.
The adjustable cylinder sizing means the U71 can be used across a wide range of European door formats, making compatibility a non-issue.
Smart Home Integration Option
When paired with WELOCK’s WiFibox3 gateway, homeowners can unlock remote control of the U71 from anywhere in the world. This enables:
- Remote unlocking and lock status checks
- Real-time entry history and access notifications
- Voice-assistant integration including Alexa
The WiFibox3 upgrade transforms the U71 from a smart cylinder into a fully cloud-connected home security device. Whether granting someone access while you are away or monitoring entries during travel, remote communication adds another layer of convenience and peace of mind.
Alexa compatibility provides additional hands-free control for users who incorporate voice automation into their household.
