Smarter Access Starts Here — Meet the WELOCK Smart Lock U81
The WELOCK Smart Lock U81 blends cutting-edge security with user-focused design.
It supports multiple unlocking methods: fingerprint, smartphone app, RFID card, and traditional key backup.
This flexibility ensures every household member finds it easy to use — no more fumbling for keys.
Built from durable materials, the lock resists tampering, moisture, and wear from daily use.
Its built-in fingerprint sensor recognizes up to 100 users, making it ideal for families, offices, and Airbnb hosts.
The WELOCK app allows you to check access history, manage user permissions, and unlock remotely (when paired with WIFIBOX3).
You can even share temporary digital keys — perfect for guests or service personnel.
Battery life lasts up to one year on standard AAA batteries, and the system sends timely low-battery alerts.
It’s a secure, stylish solution that keeps your home protected without sacrificing convenience.
Seamless Installation and Door Compatibility
The WELOCK Smart Lock U81 is designed for easy DIY installation.
It fits most European doors with a standard Euro-profile cylinder — no drilling or special wiring needed.
Before purchasing, measure your door thickness (typically 60–115 mm).
The U81’s adjustable design fits most wooden, metal, and composite doors with ease.
All required tools are included, and setup takes about 15–20 minutes.
Unlike many smart locks, the WELOCK Smart Lock U81 doesn’t require replacing the entire door handle.
You simply replace your existing cylinder, attach the external and internal modules, and pair via Bluetooth.
The lock also supports mechanical emergency keys, ensuring access even if the battery runs out.
This thoughtful design addresses one of the most common user concerns: being locked out due to battery failure.
Power and Backup You Can Rely On
Even smart devices need smart backup.
The WELOCK Smart Lock U81 ensures you’ll never be stranded.
In addition to its long battery life, it includes a discreet mechanical key slot
If the lock’s batteries deplete completely, simply plug in a power bank to the external port, unlock, and replace the batteries at your convenience.
This dual protection guarantees that your security system remains functional no matter the circumstances.
Smarter Living with WELOCK and WIFIBOX3
The WELOCK Smart Lock U81 takes full advantage of smart home technology when paired with WIFIBOX3.
This small Wi-Fi bridge connects your lock to Alexa, and Home Assistant, enabling full remote control and automation.
With WIFIBOX3, you can check lock status from anywhere, receive instant notifications, and lock or unlock doors using voice commands.
For example, say, “Alexa, lock the front door,” and the U81 responds instantly.
It’s important to note that these smart assistant features require the WIFIBOX3 connection to function.
Without it, the lock operates locally via Bluetooth and the WELOCK app.
This setup combines security and flexibility — great for managing multiple doors or granting access while away.
Your smartphone becomes the master key, while WELOCK ensures every entry is recorded and protected by advanced encryption.
