This keyless entry solution offers biometrics, app control, and an easy installation process, bringing the future of locking technology to your home.
This model’s standout features include quick fingerprint recognition and a reliable touchscreen keypad, making unlocking your front door simple for everyone in your household. DESLOC integrates voice assistant compatibility and supports remote management when paired with its optional gateway, giving you peace of mind both onsite and away.
Designed for a variety of home setups, this device leverages a battery powered lock system for long-lasting, low-maintenance operation. The inclusion of a physical key backup ensures you’re never locked out, even in emergency scenarios.
Its compliance with BHMA Grade 3 standards means you gain enhanced safety without a complex installation. The B200’s thoughtful details, like anti-peeping PIN codes and auto-lock feature, help balance convenience with data privacy for homeowners prioritizing security.
Key Features of the smart lock
- Multi-Mode Unlocking: Access the device via fingerprint lock, PIN, app control, IC cards, Bluetooth door lock functionality, and two standard keys for emergencies.
- Long Battery Life: Enjoy up to 12 months on a set of AA batteries, complete with low-battery alerts and USB Type-C emergency power.
- Smart Home Integration: Enable voice control with Alexa and Google Assistant plus scheduled and temporary access codes for guests—perfect for the connected smart home ecosystem.
- Durable & Secure: Engineered with IP54 weather resistance and anti-peeping protection, this digital deadbolt stays reliable in harsh winters or sweltering summers.
Real-World Performance Testing
During real-world testing, the smart lock demonstrated outstanding speed, unlocking with fingerprints in under 0.3 seconds and recognizing up to 50 different users. The home biometrics sensor maintained 99% accuracy, and the touchscreen keypad responded reliably even with damp hands.
This product’s Bluetooth app connects within a 2-meter range, allowing you to manage settings, generate time-limited codes for guests, and monitor access logs on your mobile device. Scheduled access codes worked flawlessly for short-term rentals, enhancing door security with minimal effort.
Battery performance held steady for ten months during our test, thanks to intermittent use and the auto-lock feature, which can be set anywhere from 5 seconds to 15 minutes. Installation was truly straightforward—requiring only a screwdriver and about 15 minutes.
Some limitations noted: the app offers full remote management only with the optional G2 Gateway accessory. Also, the exterior build feels lighter than a traditional metal deadbolt, although it passed every everyday test. For another look at app connected security, see our guide to fingerprint-based locks.

How It Compares to Alternatives
Compared with competitor models like the Ultraloq UL3 and August Wi-Fi Smart Lock, this product offers faster fingerprint recognition and more code storage at a similar price point. The B200’s battery life rivals the Schlage Encode, though it requires a separate G2 Gateway for remote access.
While the Ultraloq offers a slightly sturdier feel, the DESLOC’s seamless integration with smart home systems and flexibility via app control set it apart for users who value a broad feature set in a modern digital deadbolt.
Who Should Buy This Product?
This tool is ideal for homeowners who want simple, keyless entry backed by robust access control. Busy families benefit from storing multiple fingerprints and scheduled guest codes, while short-term rental owners will appreciate automatic access control via the app.
If you require commercial-grade hardware or full wireless remote access without additional accessories, you may want to consider higher-end models. However, this solution strikes a smart balance of price, security, and feature-rich convenience for most households.
