Desloc Smart Lock D110 Plus
The Desloc D110 Plus is a Wi-Fi-enabled smart lock that offers a broad set of unlocking methods, including a fingerprint reader, a touch-screen keypad, an IC card, and a traditional key. In addition to mobile app control, it supports Alexa and Google Assistant voice commands. It’s straightforward to install and, at $159.99, delivers solid value for a versatile smart-lock system. For even broader compatibility, the Ultraloq Bolt Fingerprint (usually $199.99 but often found at $139.99) covers nearly every major smart home platform and mirrors the Desloc’s array of authentication options, earning it our Editors’ Choice designation for smart locks.
Design and Features: Sleek, Durable, Weather-Resistant
Available in black or silver, the Desloc Smart Lock D110 Plus is housed in an aluminum-alloy enclosure with an IP54 weatherproof rating, protecting it from dust and rain. It’s a complete lock assembly designed to fit doors 1-3/8 to 2 inches thick, using a 2-1/8-inch hole diameter. The package includes interior and exterior escutcheons, mounting and strike-plate hardware, two physical keys, two IC cards, and a user manual. Four AA batteries power the unit, expected to last up to six months with normal use, though batteries are not included.
The exterior escutcheon measures 6.1 by 2.9 by 1.1 inches (HWD) and features a backlit touch-screen keypad with numeric keys 0–9, a lock/unlock button, and a menu button for programming without the app. At the top of the keypad is a small embedded display that shows options when the menu button is pressed, plus information like Wi-Fi signal strength, battery life, and whether recent unlock attempts succeeded or failed.
Between the status display and the keypad sits a fingerprint reader, and beneath the keypad is a traditional keyway. The D110 Plus stores up to 50 fingerprint profiles and up to 100 PIN codes, and you can program two IC-card fobs for specific users. A USB-C port along the bottom edge provides emergency power if the batteries run low. (Some competing locks, such as Yale’s Assure Lock 2, also offer external charging options when the battery dies.)
The interior escutcheon measures 6.2 by 2.7 by 1.1 inches (HWD) and includes a bottom thumb-turn. Behind a removable panel are the battery compartment and a reset button used to restore factory settings.
Software and Settings: Broad Access, Robust Security
The D110 Plus is managed through the Desloc mobile app for iOS and Android. On the My Devices screen, the lock appears with its own panel showing status (locked or unlocked), Wi-Fi signal strength, and battery level. Tapping the panel reveals a detailed view with a lock/unlock slider, a live camera-like image of the lock, and additional control options. The app also logs events, listing times the door was locked or unlocked.
Under the two tabs at the bottom—Assign Access and Settings—you can create users, assign PIN codes, register fingerprints, and program IC cards. You can grant visitors Always (24/7) or One-Pass (one-time) access, and you can set access schedules for defined time periods.
The Settings section offers Vacation mode (restricts unlocking to Always and One-Pass users), Auto-Lock, and a timer to auto-engage the lock. You can enable a range of security features, including Anti-Peeping Passcodes (adding random digits before or after your PIN to confuse onlookers) and Failed Attempt Protection (limits consecutive wrong codes before the lock enters a three-minute lockdown and triggers an alert). There’s also an Anti-Hijack feature to create a special passcode or register a specific fingerprint to alert all linked users and a designated emergency contact in case of danger.
Third-party integrations include Alexa and Google Assistant. By comparison, the Ultraloq Bolt Fingerprint expands compatibility with Apple HomeKit, IFTTT, Samsung SmartThings, plus Alexa and Google.
Installation and Performance: Quick Setup, Precise Operation
Setting up the D110 Plus was as straightforward as installing a typical deadbolt. After removing the old lock, I mounted the new deadbolt assembly and strike, then attached the exterior escutcheon to the mounting plate with the included screws. I connected the exterior and interior data cables and mounted the interior cable onto the plate.
Next, I downloaded the Desloc app, created an account, and added the device. I verified battery installation, scanned the QR code on the removable battery cover to pair the lock, and followed the prompts to create a passcode and register a fingerprint. Finally, I entered my Wi-Fi credentials to complete the setup.
In testing, the D110 Plus performed flawlessly. Fingerprint scans were quick and reliable, the keypad was responsive and well-lit, and the One-Pass assignments and user access schedules worked as expected. Security features like Anti-Hijack, Auto-Lock, and Anti-Peeping Passcodes functioned correctly. Voice control with Alexa was immediate, and an Alexa automation to lock the door when a motion sensor detected activity from a Reolink Elite Floodlight consistently worked.
Conclusion: A versatile, feature-rich smart lock that blends convenience with solid security. It stands up well to competitors and delivers broad access options that can simplify daily routines while offering thoughtful protection for a range of scenarios.
