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](https://www.amazon.com/-/dp/B0D9JX1Y9Z?tag=globalofertit-20) 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. ## Fit and sizing This deadbolt is designed to fit most standard US doors and can be installed with a screwdriver, without professional tools. The listed dimensions are 10 x 8 x 5 inches, and the lock is made of aluminum with a matte black finish. It is intended for an entry door, making it a natural fit for households replacing a conventional deadbolt with a keyless access system. ## Tips for day-to-day use Register fingerprints from multiple angles and keep the sensor clean to support recognition. The lock can store up to 50 fingerprints, allowing household members to use their own enrolled prints. For app access, connect through Bluetooth within close range, a G2 Gateway is needed for Wi-Fi and voice-control functions. Scheduled or temporary codes can help organize access for visitors without sharing a physical key. The B200 runs on four AA batteries, which are not included, and offers up to 12 months of battery life depending on use. A low-battery indicator helps signal when power is running low, and the USB-C emergency power port provides a backup power option. ## What to clarify **What are the ways to unlock the B200?** You can use a fingerprint, PIN code, the app, eKeys, key fobs, a physical key, or compatible voice control.
