DESLOC B200 Smart Deadbolt with Fingerprint, App Control and Auto-Lock

For households that want keyless entry without giving up familiar backup options, the DESLOC B200 combines fingerprint recognition with PIN codes, app access, eKeys, key fobs, physical keys, and voice control. Its auto-lock feature adds a hands-free locking option for an entry door, while multiple ways to enter let household members choose what works for them.

The fingerprint sensor uses self-learning AI recognition and supports up to 50 fingerprints. Bluetooth connects the lock with the TTLock app nearby, where you can manage access and create scheduled or temporary codes for family, guests, or short-term visitors. What makes this setup practical for a busy entryway? It gives you more than one way to unlock the door, plus a way to manage codes without handing out a physical key.

Highlights

The B200’s fingerprint, PIN, key, and app options help accommodate different routines at the same door. Fingerprint access can be useful when your hands are occupied, while temporary codes offer a convenient way to provide guest access. The auto-lock feature is designed to lock the deadbolt automatically, supporting a more consistent everyday routine.

For voice control with amazon Alexa or Google Assistant, and Wi-Fi access, a G2 Gateway is required and sold separately. The lock also has an IP54 water-resistance rating, operates from -22°F to 158°F, and meets BHMA Grade 3 standards. These details make it suitable for an entry-door setup exposed to changing weather conditions.

Buyers praise the clean appearance and range of access features, while feedback on fingerprint recognition, connectivity, and locking reliability is mixed. That makes it useful to consider how you plan to use the different entry methods and app functions in your household.
