FAQ
Frequently Asked Questions
Everything you need to know about DESi Utopic Smart Locks, door compatibility, installation, mobile app, and battery care.
- Is the smart lock compatible with my 3-turn lock? Compatibility
During installation, Utopic series smart locks perform an automatic calibration process to recognize the characteristics of your mechanical lock. It automatically calculates and learns how many turns are needed to fully lock or unlock your door and saves the settings in memory.
- How can I know if it's suitable for my door? Compatibility
If your door uses a Euro-profile cylinder (commonly known as a barrel), Utopic series smart locks will be compatible. In standard residential doors, cylinders with a length of 66mm – 70mm are commonly used. Utopic R and Utopic 3 smart locks come with adjustable cylinders that can be extended by an extra 10mm, fitting almost all standard doors. If your door has a thicker profile, customized cylinder extensions are also available.
- Can I use my old cylinder with the smart lock? Compatibility
No. Utopic smart locks require their own high-security engineered cylinder included in the box to ensure smooth motor drive coupling and mechanical key override functionality.
- Do smart locks work on doors with multiple locking points? Compatibility
Yes. DESi smart locks feature a high-torque motor engineered specifically for European multipoint central locking systems, effortlessly throwing all bolts across multiple locking points.
- Do smart locks have a pull feature for the door latch? Compatibility
Yes. After retracting the deadbolts, our smart locks can hold the door latch pulled for a configurable amount of time (e.g. 1 to 3 seconds), allowing you to push the door open without turning a physical handle.
- Will my door be damaged during installation? Installation
No, you can install Utopic series smart locks just like replacing a standard cylinder (barrel). No extra holes, screws, or wiring are required on your door.
- Does it matter if my door opens to the right or left? Installation
No, it does not matter. During installation, your smart lock allows you to select whether your door is a left or right opening door via the easy setup wizard, adjusting its rotation direction accordingly.
- Can I install everything myself (DIY)? Installation
Yes, all installation steps can be easily completed by following the user manual and step-by-step installation videos. The only tool typically needed is a screwdriver. Please make sure your door does not have severe friction or sagging that impedes smooth mechanical turning before mounting.
- Can I move the lock to another house or door if I move? Installation
Yes, the installation is 100% reversible. When moving to a new house, you can reinstall your original cylinder back into the old door and take your DESi Utopic lock with you to the new door.
- What is the average installation time for smart locks? Installation
The physical installation generally takes between 3 to 5 minutes. Replacing the cylinder is as simple as removing a single fixing screw on the door edge, sliding the cylinder in, and tightening it back.
- Can I still open the door with a physical key after installation? Operation
Yes, absolutely. The smart lock features full physical key override from the outside. You can use your physical high-security key at any time, including emergencies or power loss.
- Can the smart lock automatically lock and unlock? Operation
Yes. Our Utopic series smart locks automatically perform full-turn locking and unlocking with a single tap from the smartphone app, fingerprint reader, keypad, or wireless remote control.
- How can I get additional physical keys? Operation
Utopic cylinders come with 5 physical high-security keys included in the box. Additional duplicate keys can be obtained directly from DESi authorized service partners using your security code card.
- Can I use the smart lock for commercial offices or businesses? Operation
Yes. DESi smart locks are widely used in offices, dental clinics, co-working spaces, and boutique businesses to streamline staff entry and eliminate lost office keys.
- Can I grant access only to specific people during scheduled hours? Operation
Yes, through the DESi mobile application, you can assign customized user levels. You can define recurring weekly schedules or temporary access windows (e.g., for cleaning staff or service personnel).
- Are DESi smart locks vulnerable to digital hacking? Operation
All DESi smart locks communicate using multi-layer bank-grade AES 128/256-bit encryption protocols with rolling security codes, strictly preventing replay and sniffing attacks.
- Can I provide temporary access for Airbnb guests or visitors? Operation
Yes. You can generate time-limited guest invitations or temporary keypad PIN codes that automatically expire after check-out time without requiring you to be at the property.
- Does the lock feature an automatic re-locking timer? Operation
Yes. You can enable the auto-lock feature in the mobile app and configure a timeout (e.g. 15, 30, or 60 seconds). Once you enter or exit, the lock will secure the door behind you automatically.
- Can the smart lock be controlled remotely via the internet? Connectivity
Yes. When paired with the DESi Wi-Fi Smart Bridge, you can unlock/lock your door, check lock status, and receive real-time alerts from anywhere in the world.
- Can multiple family members use the smart lock? Connectivity
Yes. The master administrator can invite family members via the app, allowing everyone to unlock the door using their own smartphone, keypad PIN, or fingerprint.
- Can I see audit history and who opened the door? Connectivity
Yes. Every locking and unlocking event (including timestamp and user ID) is logged. With the Wi-Fi Bridge connected, you can review activity history and receive instant push notifications on your phone.
- Does the smart lock require an active internet connection to work? Connectivity
No. Standard operation works completely offline over high-security Bluetooth, keypads, and fingerprints. Internet connection is only required if you wish to control the lock remotely or receive notifications via the Wi-Fi Bridge.
- How do I share digital keys with friends or guests? Connectivity
You can send an encrypted digital e-Key directly from the DESi app to the recipient's phone number. The guest simply downloads the app and taps to unlock during their allowed time period.
- Can I open my door if the battery dies or my phone runs out of charge? Battery
Yes. You can always use your physical mechanical key from the outside. Additionally, if the smart lock battery is depleted, you can connect an external power bank or emergency battery to the micro-USB/Type-C charging port to power it up instantly.
- How long does the battery last and how often should I charge it? Battery
Under normal domestic use (approx. 10 operations per day), a single charge lasts between 1.5 to 2.5 months. The battery percentage can be monitored in the app, and the lock emits an audible warning tone when the battery drops below 20%.
- Can smart locks handle extreme hot or cold temperatures? Battery
Utopic series locks are engineered to operate smoothly across a wide temperature range (-15°C to +55°C). The motorized body is mounted indoors, shielding the electronics from external weather extremes.
- Are Utopic series locks water or moisture resistant? Battery
The main lock unit is designed for indoor residential and commercial use and should not be exposed directly to rain or high pressure water. For outdoor gates, specialized weather-protected keypad/fingerprint accessories with IP ratings are recommended.
