6 unlocking methods for absolute convenience
U71 offers advanced entry options to suit every need. You can use your fingerprint (0.3 s recognition), enter an access password, present an RFID card, unlock via the WELOCK app, use Bluetooth or, in an emergency, the classic mechanical key. Ideal for families, short-term rentals or Airbnb – the lock supports up to 100 fingerprints and 200 passwords.
Thanks to this versatility, you can easily set up different access types for family members, guests, or couriers. Each method can be managed through the WELOCK mobile app, which also shows your unlock history and allows you to create temporary access.
Fast installation and full compatibility with EU doors
WELOCK U71 is designed specifically for EU standard cylindrical locks and supports a width of 60–90 mm. You can install it without drilling or professional tools in under 5 minutes. It works with most wooden, metal, and security doors with a thickness of at least 40 mm.
The adjustable length, wireless design, and simple slide-in installation into your existing mechanism make U71 an ideal choice even for older apartments or rented properties. WELOCK also includes 2 years of warranty and a 30-day money-back guarantee.
Biometric security with 99.8% accuracy
The lock features an advanced biometric sensor with accuracy up to 99.8%, unlocking your door in just 0.3 seconds. That way, you have access even with full hands—no keys or phone needed. It’s one of the fastest and most accurate sensors in its class.
Safety is completed by automatic locking after 7–14 seconds. This way, you’ll never forget to lock up, and your home stays secure even on busy days.
Smart app with WiFi connectivity option
The WELOCK app gives you complete control over who has access and when. In the app, you can add users, set passwords, view entry history, or enable Bluetooth unlocking. With the separate WiFiBox3 module, you also get remote unlocking, voice control via Alexa, and integration with Home Assistant.
With WiFiBox3, you can generate one-time or time-limited codes for guests, workers, or couriers— all remotely. A great solution for Airbnb rentals or frequent visitors.
Long-lasting battery performance and emergency access
The lock runs on 3× AAA batteries with a battery life of 10–12 months (depending on how often you use it). If the batteries run out, you can still use a standard mechanical key. In the app, you’ll also find notifications about low battery levels, so nothing will catch you off guard.
U71 remembers all data even after you replace the batteries—no need to set anything up again. For extra security, you can reset the lock only physically, which helps prevent tampering or hacking.
Weather resistance for outdoor use
Thanks to IP65 water resistance, the WELOCK Smart Lock U71 works reliably even at -25 °C to +60 °C. It’s ideal for front doors of homes or garages. The manufacturer, however, recommends mounting under a shelter so the lock isn’t exposed to rain for long periods.
A robust build, reliable electronics, and quality workmanship make the U71 an ideal solution for long-term use—even in more demanding conditions. You get everything you need for the lock right in the box.
A complete access system of the future
Forget about searching for keys or worrying about security. With WELOCK Smart Lock U71 you get maximum comfort, secure access, modern features, and remote control—all included in a package you can install in minutes without drilling or modifying the door.
WELOCK is a global pioneer in smart locks and biometric security. As the first company, it brought fingerprint technology directly into the cylinders and continuously develops new solutions for homes and businesses.
