There is a moment every homeowner knows: arms full of groceries, one hand digging for keys, and the quiet question of whether this is finally the week you switch to a Smart lock. The DESLOC B200 makes that switch easy because it starts with the thing that actually sells smart locks, a fingerprint reader that opens the door in about a second. It is a silver deadbolt with a touchscreen keypad, Bluetooth app control, auto lock, and a battery rated for twelve months, all wrapped in a BHMA Grade 3 security rating. I put one on a busy front door for three weeks to find out whether the promise holds up under real daily use.

Design and Build
The B200 has a clean, modern face that does not scream smart gadget. The silver finish matches most door hardware, the touchscreen keypad sits flush in the body, and the fingerprint sensor hides under the display in a way that reads naturally as you reach for the door. On the inside, the unit is compact enough to avoid the bulky look of some competitors, and the thumb turn feels solid rather than plasticky.
Build quality is reassuring for a security device. The metal housing has no flex, the keypad buttons register cleanly, and the included gasket protects against weather on an exterior door. The battery compartment sits on the inside of the lock, which means no exposed screws on the outside face, a small detail that adds a layer of security against tampering. It is not the last word in heavyweight fortress hardware, but it looks and feels appropriate for a modern residential entryway.
Key Features
Fingerprint unlock is the marquee feature, and it performs like one. The reader registered my print in under a second and worked through the majority of attempts without a second try, including after light rain left the sensor slightly damp. The B200 stores multiple fingerprints, so every adult in the house can program their own, and a child who is tall enough to reach the reader can use it too. Registration took a few seconds per finger, and the lock did not demand constant re-scans the way some budget readers do.
Beyond the fingerprint, the touchscreen keypad accepts PIN codes for guests, cleaners, and contractors, and you can revoke those codes from the app at any time. Auto lock is the feature that quietly improves your life: set the delay and the deadbolt throws itself behind you, ending the nagging question of whether the door got locked. If you want to compare the current price with other smart deadbolts in this class, the Amazon listing for the DESLOC B200 smart deadbolt is a useful reference.
Real-World Performance
The fingerprint reader became the routine within a day. Family members reached for the reader before they reached for the keypad, which is the strongest sign that a smart lock has won you over, and the success rate held steady across the three weeks. The keypad worked well as a backup for the days when wet hands or a smudged sensor defeated the reader, and the buttons light up at night, which is a genuine convenience in the dark.
The app handled the everyday jobs well: adding a temporary code for a house sitter took about a minute, and the lock reported its status reliably while in range. Auto lock did its job without complaint, and the deadbolt threw smoothly every time, though I recommend testing the delay setting with a range of walks, because the sensor needs a clear second to re-lock after the door closes. Battery life is the other headline number. Twelve months is the manufacturer estimate, and after three weeks the app reported full strength, so I cannot speak to the full year from experience, but the low battery warning system is straightforward and the physical key cylinder remains as a backup.
The one genuine friction point is connectivity. The B200 is a Bluetooth-only lock, so remote control through the app works only when you are within range. A bridge or gateway would unlock remote access, and for a family that wants to check the door from work, that is a real consideration rather than a deal breaker. For most people who are physically at the door every day, the fingerprint does the heavy lifting anyway.
Pros and Cons
Pros:
- Fast, reliable fingerprint unlock that works in most conditions
- Touchscreen keypad with programmable guest codes
- Auto lock ends the did-I-lock-it worry
- BHMA Grade 3 security rating for a residential front door
- Physical key backup means you are never locked out
- DIY installation takes about 30 minutes with one screwdriver
Cons:
- Bluetooth-only means no true remote access without a bridge
- Fingerprint reader can falter with very wet or very dirty hands
- Battery replacement requires access from inside the lock
How It Compares
Smart deadbolts in this range split between fingerprint-first models like the B200 and keypad-first models without biometrics, with Wi-Fi options adding remote control. I compared the B200 against a keypad-only smart deadbolt and a Wi-Fi connected smart lock to see where the trade-offs land.
| Feature | DESLOC B200 | Keypad-Only Smart Deadbolt | Wi-Fi Smart Lock |
|---|---|---|---|
| Fingerprint unlock | Yes | No | Varies |
| Connection | Bluetooth | Varies | Wi-Fi |
| Remote access | No (needs bridge) | Varies | Yes |
| Auto lock | Yes | Varies | Yes |
| Key backup | Yes | Varies | Varies |
| Installation | Simple DIY | Simple DIY | Simple DIY |
Against a keypad-only deadbolt, the B200 wins on convenience because a fingerprint beats typing a code, especially with cold hands. Against a Wi-Fi lock, the B200 trades remote control for a lower price and a simpler install, which is a fair trade for anyone who mostly wants to walk up and unlock the door. The BHMA Grade 3 rating matches the security level most homeowners want, and the key backup makes the Bluetooth limitation easy to live with.
Who Should Buy It
Buy the DESLOC B200 if you want to stop digging for keys, if you have frequent visitors or contractors who need temporary access, or if you want auto lock without the complexity of a full smart home system. It is ideal for families where everyone carries the same bag of keys and no one can find them, and the installation is approachable enough for a first time buyer.
Skip it if you need to control the lock from across town without extra hardware, if you are already committed to a Wi-Fi smart home ecosystem, or if you want a lock that works with a voice assistant out of the box. For everyone else, the fingerprint-first design is the fastest path to keyless living. You can check the current price for the DESLOC B200 on Amazon when you are ready to make the switch.
How We Test
I installed the B200 on a working front door and used it as the only lock on that door for three weeks, tracking fingerprint success rate, keypad reliability, auto lock timing, and app behavior across daily use. I tested the fingerprint reader with dry, damp, and dirty hands, and I confirmed that the temporary guest code system revokes correctly from the app.
I measured installation time and checked the BHMA Grade 3 security claims against the physical build rather than relying on marketing copy. I did not test the lock against a dedicated intruder attack, and I did not leave it in extreme cold, since the test door faces a mild climate.

DESLOC B200 Smart Deadbolt: Questions People Ask
Does the DESLOC B200 smart lock work with Wi-Fi or only Bluetooth?
The B200 connects to your phone over Bluetooth, so remote access requires the included range of the connection or a paired bridge. There is no built-in Wi-Fi radio in this model, so plan your use around that limitation.
How long does the battery last on the DESLOC B200?
DESLOC rates the battery for roughly 12 months of normal use, and the low battery warnings appear well before the lock stops responding, so you have time to swap in fresh cells.
Can I still use a physical key with the DESLOC B200?
Yes. The B200 keeps a traditional key cylinder as a backup, so you are never locked out if the battery dies completely or the electronics fail.
Is the DESLOC B200 difficult to install on an existing door?
No. It replaces a standard single cylinder deadbolt in about 30 minutes with a screwdriver, and the instructions are clear enough for a first time installer to follow without help.
