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.

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.

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.

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.

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.

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.

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.

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.

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.

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).

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.

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.

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.

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.

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.

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.

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.

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%.

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.

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.
