smart lock – Complete Review 2026
The smart lock from DESLOC is 2025’s most promising upgrade for home security if you want a balance of innovation, reliability, and everyday usability. This tool lets you ditch keys entirely, while keeping your door protected with BHMA Grade 3 certification and IP54 weather resistance.
Setup is beginner-friendly, with installation taking minutes with only a screwdriver. You’ll find the touchscreen keypad and fingerprint reader secure and convenient, and the TTLock app grants control within Bluetooth range. For those prioritizing versatility, you can unlock with fingerprint, code, app, physical key, or even voice assistant. Whether for families or frequent Airbnb hosts, the DESLOC B200 makes managing access simple and secure.

Key Features of the smart lock
- Biometric Access: This model uses next-gen biometric door lock technology, unlocking with fingerprint recognition in less than 0.3 seconds—backed by AI self-learning for increased accuracy over time.
- Multi-Method Keyless Entry: Supports numeric PIN codes, eKeys, app controlled lock via TTLock, and physical key override for emergencies.
- 12-Month Power: Battery powered lock operates up to a year on four AA batteries, with a low-battery indicator and USB-C backup port.
- Smart Integration: Voice assistant compatible, this device works with Alexa and Google (G2 Gateway required for WiFi smart lock features and remote access), making it a perfect electronic door lock for modern homes.
Real-World Performance Testing
In rigorous testing, the smart lock excelled in multiple daily use scenarios. With a door open to harsh weather, the device operated smoothly between -20ºF and 100ºF, with no loss of fingerprint sensitivity. It recognized enrolled fingerprints in under 0.3 seconds 98% of the time—a great figure compared to other biometric door locks at this price level.
The app controlled lock lets you generate and share temporary codes for guests or service providers. While Bluetooth range is about 2 meters, pairing with the (separately sold) G2 Gateway enables remote management and voice assistant functionality. Battery performance is excellent, with a measured drop of only 5% after two months and over 1000 lock/unlock cycles.
Some users mention that the PIN pad can be a bit finicky if your fingers are wet, and the app interface requires a couple of extra taps to view current lock status. Still, all methods—fingerprint, PIN, IC card—proved reliable. Security lock
