## Description

Made of metal, the DESLOC B200 is a WiFi fingerprint deadbolt for home use. Its keypad and app add convenient keyless entry options. Auto-lock helps manage locking after you leave, while the app supports access codes for guests.

## Strengths

Choose how to enter: use fingerprint recognition, a PIN, the TTLock app, an eKey, a fob, voice control through Alexa or Google Voice Assistant, or either of the two mechanical keys. The fingerprint reader is rated to unlock in less than 0.3 seconds, and its AI learning feature is designed to adapt over time. Multiple access methods make the B200 useful for everyday arrivals as well as sharing entry with household members or visitors.

Bluetooth connects the lock to the TTLock app within 2 meters. For remote control, connect it through a G2 Gateway, the app can also generate temporary access codes with scheduled times for friends or guests. Auto-lock, privacy mode, and anti-peeping PIN protection add practical control options, while the IP54 rating and stated operating range of -22°F to 158°F support use in varied conditions.

## What to know

The lock is black, has a modern style, and measures 10 x 8 x 5 inches. Its battery power comes from four AA batteries, with an estimated life of around 12 months depending on use. A low-battery indicator provides a prompt, and a USB Type-C emergency power port offers another way to supply power when needed. The four AA batteries are not included.

For installation, the door should be 1-3/8 to 2 inches thick, with a 2-1/8-inch hole and a 2-3/8- or 2-3/4-inch backset. The deadbolt needs to engage cleanly when the door is fully closed, correct door-opening direction in the app is important for the auto-lock function. Installation uses a screwdriver. Customer feedback highlights the design and choice of entry methods, while reports on fingerprint recognition, connectivity, and overall reliability are mixed, so the available access methods give you flexibility in how you use the lock.

## How to use it

Set up the lock in the TTLock app, then pair over Bluetooth for nearby app control. Add a G2 Gateway connection for remote access. Use the keypad to enter a PIN, the fingerprint reader for biometric entry, or a key or other supported method as needed. To lock manually from outside, press and hold # for 2 seconds. For daily use, confirm the deadbolt moves freely with the door fully closed and select the correct opening direction in the app.

## Practical questions

**Can I control the lock when I’m away from home?** Yes. Pair it with the TTLock app and connect it through a G2 Gateway to enable remote control. Bluetooth app control works within 2 meters.

**What door measurements does the B200 fit?** The stated fit is a door thickness of 1-3/8 to 2 inches, a 2-1/8-inch door hole, and a 2-3/8- or 2-3/4-inch backset.

**What are the ways to unlock it?** Use fingerprint recognition, a PIN code, app control, an eKey, a fob, voice control through Alexa or Google Voice Assistant, or one of the two mechanical keys.

## When it makes sense

The DESLOC B200 suits a home entry where you want more than one way to unlock the door and the option to manage guest access through an app. Its keypad, fingerprint reader, mechanical keys, and remote-control capability offer practical choices for daily entry, while scheduled temporary codes help organize access for visitors.
