Utopic RXSmart Lock + Smart Bridge
Don't worry about forgetting, losing or carrying your keys! Control your door from anywhere with Google Home, Alexa and Home Assistant. The Smart Bridge is included.
Nothing on the outside of your door.
From the outside, Utopic gives no sign that your door has a smart lock. Semi-smart locks that sit outside and are turned by hand are always exposed to attack: the electronics can be broken off to reach the cylinder. With the Utopic series the device is entirely inside, so it creates no security weakness.
A lock you turn by hand is not a smart lock. A smart lock, like Utopic, performs locking, unlocking and latch retraction with a motor, on your behalf.
- Electronics on the outside, within anyone's reach
- It is obvious from outside that you have a smart lock
- Always exposed to attack
- The electronics can be broken off to reach the cylinder
- No motor, turned by hand: not a real smart lock
- The device is fully inside the door
- No visible sign of a smart lock from outside
- No electronic part to tamper with from outside
- Creates no security weakness
- Fully motorised: locks, unlocks and retracts the latch by itself
What makes DESi different.
A smart lock is not an electronic gadget; it is a security system that directly affects your family's safety. That is why the real difference lies not in the device, but in the company behind it. DESi is one of Türkiye's largest smart lock manufacturers, built on 100% domestic capital and in-house engineering.
Proprietary, patented technology
Patented solutions from our own R&D, such as the virtual door handle and turn-count learning, have become benchmarks in the industry. Our designs are protected by design registration.
One of Türkiye's largest manufacturers
One of the largest manufacturers in its sector by production capacity and market share.
In-house R&D and software
Software, hardware and design are developed entirely in Türkiye by our own engineering team. Systems are continuously improved with software updates and security issues are addressed immediately.
Wide service network
One of the few companies able to provide on-site technical support across all 81 provinces of Türkiye.
Exporting to Europe
Used in more than 50 countries with CE certification and international security standards.
Spare parts guarantee
Spare parts and support are provided throughout the product's life cycle. DESi is your single point of contact.
Install without changing your existing cylinder.
Install by simply tightening 4 screws; no lock replacement, no key cutting. Thanks to the patented feature exclusive to the Utopic RX series, you can still open your door from outside with your key at any time, so there is no need for a panic cylinder.
Steel strength. Advanced security.
Metal gears made of specially engineered steel and a robust metal chassis keep the Utopic RX running reliably for years. On the digital side, AES-256-GCM encryption protects communication between the smart lock and DESi systems.
Your door unlocks as you arrive.
Thanks to Geofence technology, your door unlocks automatically as you approach home, without opening the app. Your phone starts communicating with the lock when it enters the geofence area and the door unlocks as you get closer.
Set the app's location permission to "Always". Because the feature uses GPS, unlocking may be delayed where the GPS signal is weak. Waking your phone's screen may improve response time.
90 dB built-in alarm system.
Utopic RX adds an extra layer of security. Built-in impact detection instantly detects tampering attempts and sends real-time notifications to your phone (via the included DESi Smart Bridge). The 90 dB siren can also be triggered manually with the panic button or remotely via the Smart Bridge.
*Available as an in-app purchase with a monthly or annual subscription.
Open with fingerprint or PIN.
Lock or unlock your door by scanning your fingerprint or entering your PIN code.
Fingerprint reader sold separately.
No keypad on your door? No problem!
Create one-time e-keys in the app and share them with visitors, so they can open your door with the DESi Smart app on their own phones.
The smartest of its series.
Utopic RX learns your daily usage habits and slows its connection scanning when not in use to save battery. If left idle for a long time, it shuts down completely and enters standby. Different connection modes let you set your own energy balance.
Track every activity with detailed reports.
See lock and unlock activity with the date, time and user who performed it. With the DESi Smart Bridge, monitor access in real time from anywhere.
Various installation options.
Utopic RX mounts onto your existing cylinder; a minimum 2 mm gap between the cylinder and the door surface is required. If your cylinder does not protrude beyond the surface, use the included 3M adhesive tape to mount directly on the door. For thumbturn cylinders, remove the thumbturn and attach the plastic adapter included in the box.
Up to 6 months of battery life.
The rechargeable lithium battery lasts up to 6 months per charge, depending on the connection mode you choose (fast, adaptive or slow). Charge it with the included Type-C cable.
Check battery status anytime in the DESi Smart app. If you forget to charge, you can always open your door with your key.
6 months applies to energy saving mode.
Adjustable latch retraction durations.
After unlocking, keep the latch retracted for a duration you choose, or unlock without retracting the latch at all. All latch settings are in the advanced menu.
Long-press the unlock button in the app to access these options.
Invite users with the Smart Bridge.
With the included DESi Smart Bridge, invite users by email and grant access on specific days or hours. Manage or change these permissions anytime, from anywhere.
