U-Lock is from the ground up to be right for every front door. It's powerful enough to remotely lock or unlock without the need of Wi-Fi hub and is simple enough to grant access or deny access to residents. Most importantly, all these wonderful features housed in a design by German sports car designer to ensure that it looks and feels like it’s part of your house. In addition, U-Lock is one of the few devices on the market with WiFi and Bluetooth built-in and offers up to one year of lock battery life (with just 4 AA batteries), thanks to SGUDA's professional R&D team in Taiwan. The advantage of built-in WiFi is that users don't have to pay extra for a WiFi hub, while greatly enhance the overall security. The SGUDA lock comes with its own bespoke app. The app is not only for opening or locking, it also allows you to change user settings, see the status of the lock, receive real-time updates on what is happening, manage access and even customize sound and music. Packaged in a straightforward, no-nonsense, and elegant user-interface designed by an award-winning design team.
