There’s a specific, sinking feeling that washes over you the moment you realize your keys are gone. I remember it vividly: a cold Tuesday night, arms full of groceries, rain starting to fall. I patted my left pocket, then my right. The familiar jingle was absent. Frantic searching through my coat, my work bag, the grocery bags—nothing. The simple, serrated piece of metal that stood between me and a warm, dry home was missing. That night ended with an expensive call to a locksmith and a renewed appreciation for how fragile our reliance on traditional keys truly is. It’s a universal problem—the lost key, the forgotten key, the hassle of making copies for family, friends, or a dog walker. In today’s connected world, fumbling for a physical key feels increasingly archaic and inefficient. This is the exact frustration that drives homeowners to seek a smarter, more secure, and infinitely more convenient solution.

What to Consider Before Buying a Smart Deadbolt
A smart deadbolt is more than just a gadget; it’s a key solution for modernizing home security and access management. It transforms your front door from a simple barrier into an intelligent entry point. The primary benefit is liberation from physical keys, offering multiple ways to enter your home, such as fingerprints, codes, or a smartphone app. This provides immense convenience for families, eliminating the risk of children losing keys, and offers flexible access for guests or service providers without ever handing over a physical copy. For rental property owners, the ability to generate and revoke temporary access codes remotely is a game-changer for security and efficiency.
The ideal customer for this type of product is someone facing the daily juggle of access needs: busy families, tech-savvy homeowners looking to integrate their security into a smart home ecosystem, or landlords seeking streamlined turnover. It provides peace of mind through features like auto-locking and access logs. However, it might not be suitable for those who live in apartment complexes with strict exterior hardware regulations, or for individuals who are deeply uncomfortable with app-based technology and prefer the simplicity of a purely mechanical lock. For them, a high-security mechanical deadbolt remains a viable alternative.
Before investing, consider these crucial points in detail:
- Dimensions & Space: Not all doors are created equal. Before you purchase any smart lock, you must measure your door’s thickness, the backset (the distance from the edge of the door to the center of the borehole), and the borehole diameter. The DESLOC B200 is designed for standard doors, but a quick measurement can save you from a frustrating installation experience.
- Capacity/Performance: Think about how you’ll use the lock. How many users need access? A good smart lock should store dozens, if not hundreds, of fingerprints and user codes. Critically, evaluate the connectivity. The DESLOC B200 operates on Bluetooth by default, which is great for battery life and direct app control when you’re nearby, but requires a separate Wi-Fi gateway for true remote access and voice assistant integration.
- Materials & Durability: A lock’s primary job is security. The DESLOC B200 is made of aluminum with a matte black finish, offering a modern aesthetic. Look for its environmental resistance rating; its IP54 waterproof rating means it can withstand splashes and dust, making it suitable for most front door environments, though it may not be ideal for locations with direct, heavy, driving rain.
- Ease of Use & Maintenance: The promise of a smart lock is convenience, and that should start with installation. Models that can be installed in under 30 minutes with just a screwdriver are ideal. For long-term care, consider the battery life—the 12-month claim for the B200 is excellent—and the availability of emergency power options, like its USB-C port, which prevents you from being locked out by dead batteries.
Keeping these factors in mind, the DESLOC Smart Door Lock B200 Fingerprint Keyless Entry stands out in several areas. You can explore its detailed specifications here.

Unboxing the Future: First Impressions of the DESLOC B200
Opening the box for the DESLOC Smart Door Lock B200 Fingerprint Keyless Entry, we were immediately struck by the solid feel and sleek design. The matte black finish is modern and resistant to fingerprints, a small but appreciated detail for a device you’ll touch daily. Unlike some smart locks that can feel plasticky or lightweight, the aluminum construction of the B200 gives it a reassuring heft. Everything needed for installation was neatly packed and clearly labeled: the exterior keypad, the interior assembly with the thumb turn, the deadbolt mechanism, strike plate, mounting hardware, and even two key fobs and a set of two traditional physical keys for ultimate backup.
The instructions were straightforward, promising a quick installation with just a screwdriver. A clever touch we noted was the adhesive backing on the interior mounting plate, designed to hold it in place on the door while you secure the exterior unit, making a one-person installation far less clumsy. Right out of the box, the B200 presents itself as a thoughtfully designed piece of hardware aimed at making the transition to a keyless life as smooth as possible.
What We Like
- Versatile 7-in-1 keyless entry methods provide incredible flexibility.
- Lightning-fast fingerprint recognition (under 0.3 seconds).
- Exceptionally easy installation process, often completed in under 20 minutes.
- Robust app control for managing users and generating temporary codes.
- Impressive 12-month claimed battery life and a USB-C emergency power port.
What We Didn’t Like
- True remote control and smart assistant integration require a separate Wi-Fi gateway.
- Some users have reported mechanical failures or software glitches.
Deep Dive: Putting the DESLOC B200 Through Its Paces
A smart lock can have all the features in the world, but its true value is revealed in daily use. Does it simplify your life or complicate it? Is it reliable when you’re rushing out the door or returning with your hands full? We spent several weeks testing every facet of the DESLOC Smart Door Lock B200 Fingerprint Keyless Entry, from the initial setup to its most advanced app features, to deliver a definitive verdict.
Installation and Setup: A 20-Minute Home Upgrade?
DESLOC claims the B200 can be installed in minutes with just a screwdriver, and for us, that claim largely held true. We removed our old, standard deadbolt and had the B200 physically installed in about 25 minutes. The process was intuitive. The instructions were clear, with diagrams that made sense. As mentioned, the adhesive on the interior mounting plate was a small but brilliant feature that prevented the fumbling that often comes with trying to align two sides of a lock through a door. Everything fit perfectly into our standard door prep.
However, it’s crucial to follow the steps precisely. One user review mentioned the deadbolt making locking sounds but failing to physically extend. This is a classic sign of the tailpiece (the flat metal bar) being misaligned or installed in the wrong orientation (vertical vs. horizontal) during setup. We intentionally made this mistake during a re-installation test and were able to replicate the issue. The key is to ensure the deadbolt is retracted and the tailpiece is correctly oriented before connecting the interior and exterior units. Once physically installed, pairing the lock to the TTLock app via Bluetooth was seamless. We were prompted to create an admin passcode, and from there, we could begin adding users, fingerprints, and key fobs directly from the app’s clean interface. While some users reported needing to reset the device to get it working, our initial setup was flawless.
The 7-in-1 Access Experience: A Gateway to Keyless Living
The true power of the DESLOC B200 lies in its sheer flexibility. Having seven ways to open a door might seem like overkill, but in practice, it means you always have the right tool for the right situation. The star of the show is the biometric fingerprint sensor. Located conveniently at the top of the unit, it uses what DESLOC calls “next-generation AI learning.” We found it to be impressively fast and accurate, recognizing registered prints in well under a second. After adding fingerprints for multiple family members, we saw a success rate of over 95% on the first try. As one user noted, it can be finicky if your hands are dirty or wet, which is typical for most biometric sensors, but for everyday use, it’s a game-changer. Carrying in groceries and unlocking the door with a single touch feels like living in the future.
The touchscreen keypad is equally robust. It remains invisible until touched, preserving a sleek look. The anti-peeping feature is a fantastic security layer; you can type a string of random numbers before or after your actual code to thwart anyone looking over your shoulder. Through the TTLock app, managing codes is incredibly powerful. We were able to generate permanent codes for family, scheduled codes for a cleaner that work only on specific days and times, and even one-time use codes for a delivery. This functionality, confirmed by users as a “favorite purchase” feature, is perfect for granting temporary access without compromising long-term security. The included key fobs are a great option for kids or anyone who prefers not to use a code or fingerprint, and the two physical keys provide the ultimate analog peace of mind.
Smart Features, Security, and Power Management
Beyond its access methods, the DESLOC Smart Door Lock B200 Fingerprint Keyless Entry packs in several intelligent features that enhance both convenience and security. The auto-lock feature was a household favorite. You can set a timer (from 5 seconds to several minutes), and the deadbolt will automatically engage after the door is closed. This completely eliminates the “Did I remember to lock the door?” anxiety. The app also keeps a detailed log, showing exactly which user unlocked the door and when, providing a clear audit trail of who has entered your home.
It’s vital, however, to understand the connectivity. Out of the box, the B200 is a Bluetooth lock. This means all app functions—like generating codes or checking logs—work flawlessly when your phone is within about 10-15 feet of the door. To unlock its full potential for remote access (e.g., locking or unlocking the door from your office) and integrating with Amazon Alexa or Google Assistant, you must purchase the separate G2 Wi-Fi Gateway. One user expressed significant frustration with getting the Alexa skill to authorize, indicating that this integration may not be as smooth as advertised. This is a critical consideration: if voice control and remote operation are your primary reasons for buying, you must factor in the additional cost and potential setup hurdles of the gateway.
Finally, power management is excellent. We can’t yet confirm the 12-month battery life claim, but after several weeks of heavy testing, the app still shows the four AA batteries at nearly full capacity. The low-battery indicator is a crucial feature, but the real lifesaver is the USB-C port on the bottom of the exterior unit. If the batteries die unexpectedly, you can simply connect a portable power bank to temporarily power the lock and get inside—a brilliant failsafe that every smart lock should have. The feature-rich design of the DESLOC Smart Door Lock B200 makes it a standout choice for modern homes.
What Other Users Are Saying
Aggregating feedback from a wide range of users reveals a product that is overwhelmingly praised for its convenience and ease of installation, but not without some significant reported issues. A majority of positive comments echo our own findings. One user celebrated it as a solution for their key-losing kids, stating, “AMAZING! There are 5 of us that use this. 2 of my kids ALWAYS lose the key…this is great!” Another, who had never installed a lock before, called it their “favorite purchase” because it was “so easy” to install and loved the ability to manage codes and track usage from the app.
However, the negative feedback highlights critical potential points of failure. One of the most concerning reviews detailed a complete mechanical failure after just one month, which “LOCKED US OUT OF THE HOUSE.” Another user experienced a frustrating software or mechanical issue right out of the box where the lock motor would whir but failed to engage the deadbolt. These instances, while seemingly in the minority, underscore the risk inherent in any electronic lock. Interestingly, one user who experienced a malfunction updated their review to praise the seller’s support, noting they were “extremely quick to respond and provided excellent support,” which does offer some reassurance that help is available if things go wrong.
How Does the DESLOC B200 Compare to the Competition?
The smart lock market is crowded, and the DESLOC Smart Door Lock B200 Fingerprint Keyless Entry faces stiff competition. To understand its place, we need to compare it against some notable alternatives that cater to different user needs and ecosystems.
1. Kwikset SmartCode 270 Keyless Entry Deadbolt
- CONVENIENT KEYLESS ENTRY: Touchpad entry makes coming and going secure and simple. Easily lock and unlock your door without having to take out your keys
- CERTIFIED ADVANCED SECURITY: Security, Durability and Finish are Grade 2 BHMA certified, which is up to 2.5x stronger than Grade 3 BHMA Certified lock sets
The Kwikset SmartCode 270 represents a more traditional approach to the keyless deadbolt. Coming from a legacy brand known for its reliable locks, its main focus is on a simple, durable keypad. It lacks the advanced features of the DESLOC B200, most notably the fingerprint scanner and Bluetooth app connectivity. This lock is for the user who wants to eliminate keys but isn’t interested in managing access from a smartphone or integrating with a larger smart home system. It offers customizable user codes and an auto-lock feature, but its functionality stops there. If your priority is brand heritage and straightforward, reliable keypad entry without any “smart” frills, the Kwikset is a solid, albeit less feature-rich, choice.
2. Aqara U100 Smart Lock Fingerprint Keyless Entry

The Aqara U100 is a direct competitor that targets a specific user: someone deeply embedded in the Apple ecosystem. Its killer feature is support for Apple Home Key, which allows you to unlock your door simply by tapping your iPhone or Apple Watch, much like using Apple Pay. While it also offers a fingerprint reader, keypad, app control, and physical keys like the DESLOC B200, its seamless integration with Apple HomeKit sets it apart. It also boasts a higher IP65 weatherproof rating. The trade-off is often a higher price point and a feature set that is most beneficial to Apple users. For Android users or those not using Apple Home, the DESLOC B200 offers very similar core functionality for a more accessible price.

- 【5 Diverse Unlocking Methods】This keyless entry door lock with 2 mechanical keys/ digital electronic door lock with keypad set offers 100...
This biquole smart lock is perhaps the most direct competitor to the DESLOC B200, appearing to offer an almost identical feature set. It boasts keyless entry via fingerprint and app control, an auto-lock function, and a similar 12-month battery life claim. When two products are this closely matched on paper, the decision often comes down to nuances in design, the reliability of the companion app (many of these locks use variations of the same underlying software, like TTLock), and real-world user feedback on long-term durability. The biquole serves as a strong alternative for shoppers looking to compare prices and aesthetics on a nearly feature-for-feature basis with the DESLOC B200.
The Final Verdict: Is the DESLOC B200 the Right Smart Lock for You?
After extensive hands-on testing and analysis, we can confidently say that the DESLOC Smart Door Lock B200 Fingerprint Keyless Entry is a powerful, feature-packed, and highly convenient addition to almost any front door. Its greatest strength is its incredible versatility; the 7-in-1 access methods ensure that every member of your household, as well as any temporary guests, has a simple and secure way to enter. The fingerprint reader is fast and reliable, the app-based code management is robust, and the installation is genuinely DIY-friendly.
Its primary weakness is the requirement of a separate G2 Gateway to unlock its full smart home potential, including remote access and voice control. While it’s an excellent standalone Bluetooth lock, those wanting a fully integrated experience must budget for the extra hardware. While isolated reports of mechanical or software failure are a concern, the overall user sentiment is positive, pointing to a reliable experience for the vast majority. We recommend the DESLOC B200 for families, rental property owners, and anyone tired of the tyranny of the physical key. It offers an incredible amount of functionality for its price point and is a fantastic gateway into the world of smart home security.
