Automatic Locking After Closing
WELOCK A91 helps secure the door automatically after it is closed, reducing the chance of leaving your home unlocked by mistake. It is a practical upgrade for busy families, rental homes, and anyone who wants a more reliable daily access routine.
Face Recognition Unlock Without Keys or Phone
With face recognition unlock, WELOCK A91 lets you open the door without taking out a key, an NFC card, or a smartphone. It is especially useful when your hands are full, when children come home from school, or when family members need quick and simple access every day.
Flexible Access for Family and Guests
The WELOCK A91 makes it easier to manage access for different people without handing out spare keys. You can create convenient access for family members, renters, guests, dog walkers, cleaners, or repair workers while keeping door access more organized through the WELOCK app.
Remote Access and Smart Home Control with WiFiBox3
With WiFiBox3, WELOCK A91 supports remote unlocking, access records, phone notifications, Alexa, Home Assistant, and intercom access control. Bluetooth control works nearby, while remote access, smart home features, and intercom control require WiFiBox3, sold separately.
Local Storage for Sensitive Access Data
WELOCK A91 stores important access information locally on the device, including face recognition data and user access settings. This helps reduce unnecessary reliance on cloud storage and gives users more confidence when using a smart lock for their home entrance.
Check Your Door Compatibility Before Ordering
WELOCK A91 is designed for compatible doors with a Euro profile cylinder structure. Before purchase, please check your cylinder type, door thickness, and door backset to make sure the lock fits correctly. This helps avoid installation problems and ensures a better smart lock experience from the start.
