DESLOC B200 Fingerprint Smart Lock with Curved Handles and Auto-Lock

Everyday use

Fingerprint access gives the DESLOC B200 a quick alternative to carrying a key, while the curved handles provide a natural grip as you enter or leave. It also supports PINs, app access, eKeys, fobs, and physical keys, so household members and visitors can use different entry methods. For a busy morning, set the auto-lock timer to secure the door after you leave. The lock is designed for front, back, side, garage, apartment, office, bedroom, laundry, and basement doors.

Why it’s worth it

The B200 combines everyday entry options with access management through the TTLock app. Bluetooth connects the lock to the app at close range, where you can create scheduled or temporary codes for family, guests, or short-term visitors. That gives you a way to share access without handing out a physical key. Alexa and Google Assistant voice control are supported with a G2 Gateway, making the lock a fit for households that want voice access as part of their setup.

A fingerprint reader that can store up to 50 prints is useful when several people need convenient entry, and the lock also retains PIN and physical-key access. Buyer feedback is mixed: customers appreciate the range of unlocking methods, while some report inconsistent fingerprint recognition or Bluetooth app connections, along with concerns about reliability over time. The multiple entry methods let you choose how to access the door, rather than relying on the fingerprint reader alone.

Buying verdict

For a home or apartment entry where different people need access, the DESLOC B200 offers more flexibility than a key-only deadbolt: use fingerprints or codes for routine entry, the app for managing visitor access, and physical keys as another option. Its curved handles, adjustable auto-lock, and multiple access methods make it especially practical for households with frequent visitors or hands-full arrivals. Choose it when you want a fingerprint smart lock with app-based access management and the option to use familiar entry methods too.
