No Keypad on Your Door? No Problem

You can create one-time e-keys through the application and share them with your visitors to allow them to open your door using the DESi Smart app on their phones.

Smartest of Its Series

The Utopic RX smart lock monitors your daily usage and proactively adjusts its activity to conserve battery power when not in use, slowing itself down. If the lock remains unused for an extended period, it automatically shuts down completely and enters standby mode. Additionally, with selectable usage modes, you can manage battery consumption yourself.

Various Installation Options

The Utopic RX smart lock mounts onto your existing cylinder. There must be a minimum gap of 2mm between the cylinder and the door surface. If the cylinder does not protrude, mount directly onto the door using the included 3M adhesive tape. For cylinders with a thumbturn, remove it and attach the plastic adapter provided in the box.

Up to 4 Months of Battery Life

Rechargeable lithium batteries provide a long-lasting battery life of 3–4 months per charge, depending on your chosen connection mode (fast, adaptive, or slow). Monitor battery status via the DESi Smart app. Even if you forget to recharge, you can always unlock your door with your keys.

Invite Users with Smart Bridge

Invite users via email and grant access permissions on specific days or hours. Manage or modify permissions anytime and anywhere.

Knock on Your Door 3 Times

If unused for days, RX reduces scanning or shuts down to save power. To wake it, simply knock 3–4 times—ready for phone, fingerprint, and more.

Hey Siri, Lock My Door!

Lock or unlock your door with a simple voice command to Siri. iOS and Android shortcuts let you act in seconds—no need to open the app.

Semi-Automatic Mode

Built-in motion sensors detect slight manual turns and automatically complete the movement. Lock your door with minimal effort; tap the device button to lock instantly.
