Overview

The CATCHFACE B17 Smart Fingerprint Keyless Entry Lock sits comfortably in the mid-range smart lock category, built for renters, short-term rental hosts, and everyday homeowners who want app-based access without spending a fortune. The lock itself has a solid zinc alloy body with a silver finish and a backlit keypad built into the handle — a more integrated look than many bolt-on smart locks. It runs on the TTLock ecosystem, which means you manage everything through the TTLock app on your phone. The handle is reversible, so it works on left- and right-handed doors. One thing to know upfront: remote access over the internet requires a separate Wi-Fi gateway, sold separately.

Features & Benefits

This smart handle lock gives you five ways to unlock your door: fingerprint, a virtual anti-peep PIN, IC cards (five come in the box), the TTLock app via Bluetooth, or a traditional physical key — two of those are included as backup. The anti-peep PIN lets you add random digits before or after your real code, which is a handy security touch. Through the app, you can create virtual keys for guests, set time-restricted access schedules, and review who came and went. There's also a passage mode for keeping the door unlocked during high-traffic moments, and a basic time attendance log that tracks entry by user — useful if you have staff or multiple tenants.

Best For

This keyless entry lock is a natural fit for Airbnb and VRBO hosts who need to hand out time-limited access codes without cutting new keys or being on-site. Apartment renters who want to avoid calling a locksmith will appreciate the roughly 20-minute installation — just a screwdriver and a drill. Small office managers can use the access log feature to track who's coming in without investing in enterprise-grade hardware. Budget-conscious homeowners who want fingerprint and app access but aren't ready for premium brands will find real value here. That said, you should be comfortable with basic app setup; this isn't a plug-and-play experience for the completely non-technical.

User Feedback

Buyers consistently point to easy installation and solid fingerprint recognition as the highlights — most report getting the lock up and running without any professional help. The zinc housing feels reasonably sturdy, though buyers coming from premium brands may notice the difference in tactile weight. Battery life gets generally positive marks, and the low-battery alert works reliably. The most common frustration is discovering that remote Wi-Fi access costs extra; many buyers don't realize the gateway is sold separately until after purchase. A handful of users also mention that the TTLock app has a learning curve, and customer support response times can be inconsistent — worth factoring in if you're relying on this lock for a rental property.

Pros

  • Five distinct unlock methods mean you're rarely stuck without a way in.
  • Installation is genuinely DIY-friendly and typically done in about 20 minutes.
  • Two physical backup keys are included, so you have a failsafe from day one.
  • The reversible handle works on both left- and right-handed doors without buying extra parts.
  • Time-limited virtual keys make guest access management straightforward for rental hosts.
  • The anti-peep PIN feature adds a thoughtful layer of security for shared or public-facing entrances.
  • Compatible with Alexa and Google Assistant for basic voice control integration.
  • Access logs let you see exactly who entered and when, directly from the app.
  • Five IC cards included in the box is a generous starting point for multi-user households.
  • Passage mode is a small but useful feature for high-traffic days like move-ins or events.

Cons

  • Wi-Fi remote access requires a separate gateway purchase that many buyers don't realize upfront.
  • The TTLock app has a noticeable learning curve for users who aren't tech-comfortable.
  • Fingerprint recognition can be unreliable with wet or very cold fingers.
  • The zinc alloy build feels lighter and less premium compared to higher-end competitors.
  • Customer support response times have been inconsistent based on buyer reports.
  • No batteries included, which is a minor but annoying oversight right out of the box.
  • Firmware updates and long-term software support are not clearly guaranteed by the brand.
  • The gateway add-on costs extra, making the true price of full remote functionality higher than the listing suggests.

Ratings

The scores below reflect our AI-driven analysis of verified global buyer reviews for the CATCHFACE B17 Smart Fingerprint Keyless Entry Lock, with spam, bot-generated, and incentivized submissions actively filtered out before any scoring was applied. We evaluated real-world feedback across installation, daily reliability, app usability, and long-term ownership experience to give you a rounded picture. Both the strengths that make buyers recommend this lock and the friction points that lead to disappointment are transparently reflected in every score.

Ease of Installation
88%
A large portion of buyers — including those who had never installed a smart lock before — report completing the swap in 20 minutes or less using only a screwdriver and a drill. The reversible handle and clear written instructions reduce the guesswork significantly, which is a real confidence boost for first-timers.
A handful of users with older door frames or non-standard backset distances ran into fit issues that required additional hardware or shimming. The drilling instructions could also be more specific about bit sizes, which caused minor confusion for some DIYers.
Fingerprint Reliability
74%
26%
Under normal, dry indoor conditions, the fingerprint sensor performs consistently and registers quickly — most users report near-instant recognition after the initial enrollment. For a lock at this price point, the day-to-day fingerprint experience is genuinely competitive.
Performance drops noticeably when fingers are wet, very cold, or worn from manual work. Several buyers in colder climates or those who work with their hands mention falling back on PIN entry more often than expected, which undercuts the convenience the fingerprint feature is supposed to deliver.
App Experience
67%
33%
The TTLock app covers the essentials well — setting up user codes, issuing time-limited virtual keys, and reviewing access logs are all doable once you get the hang of the interface. Rental hosts in particular find the guest key scheduling feature genuinely saves time during busy check-in weeks.
The app's learning curve is steeper than many buyers expect, and the UI doesn't do much to guide new users through setup. Non-tech-savvy buyers frequently mention needing to watch third-party tutorial videos just to get basic features working, which is a friction point that shouldn't exist at this stage of smart lock development.
Remote Access
58%
42%
Once the optional Wi-Fi gateway is added, remote locking, unlocking, and access log monitoring work reliably and open up the lock's full potential for rental hosts managing properties from a distance. Buyers who invested in the gateway generally rate the remote experience positively.
The gateway is not included and costs extra — a fact that catches many buyers off guard after purchase. Out of the box, the lock is Bluetooth-only, meaning you must be physically close to your door to use app control, which significantly limits the value proposition for anyone who bought it specifically for remote management.
Build Quality
71%
29%
The zinc alloy housing feels reasonably solid and the silver finish looks clean on a standard residential door. For buyers coming from a basic keyed lockset, the step up in perceived quality is noticeable and the backlit keypad adds a polished touch.
Buyers who have owned premium smart locks from established brands comment that the handle feels noticeably lighter and less substantial in hand. There are also isolated reports of surface finish wearing around the keypad after several months of daily use, which is worth noting for long-term ownership.
Value for Money
83%
Stacking up five unlock methods, smart home integration, and a built-in access log at a sub-hundred-dollar price point represents genuine value for buyers who don't need enterprise-grade security. Rental hosts especially find the cost-per-feature ratio hard to beat in this tier.
The value calculation shifts if you factor in the separately purchased Wi-Fi gateway, which pushes the total cost higher than the listing price suggests. Buyers who need full remote functionality from day one may find the true cost less compelling than the initial price implies.
Battery Life
76%
24%
Most users report battery sets lasting several months under normal residential use, which aligns with typical expectations for a Bluetooth-based smart lock. The low-battery alert through the app gives advance notice reliably, reducing the risk of being caught off guard.
Heavier users — particularly those managing high-traffic rental properties with frequent daily entries — report shorter battery intervals than expected. Batteries are also not included in the box, which is a minor but consistent complaint from first-time buyers unpacking the lock.
Access Log & Tracking
79%
21%
The time attendance log tracks every entry by user and method, which is more than enough for small offices or rental managers who just want a basic record of who came and went. Being able to pull that log from a phone rather than a dedicated device is a practical convenience.
The log interface in the TTLock app is functional but not particularly intuitive for exporting or reviewing records over long periods. Users who need detailed reporting for professional property management may find it underwhelming compared to dedicated access control systems.
Guest Access Management
81%
19%
Creating and revoking time-limited virtual keys is one of the more polished features in the TTLock ecosystem, and Airbnb hosts consistently highlight it as a major time-saver. Being able to schedule a guest key to expire automatically at checkout removes a whole layer of manual follow-up.
Setting up guest access for the first time requires navigating several steps in the app, which can be confusing without prior TTLock experience. Hosts managing multiple properties also note that the app doesn't offer a particularly clean way to organize multiple locks from a single dashboard.
Smart Home Integration
69%
31%
Alexa and Google Assistant compatibility works as advertised for basic voice commands like locking the door or checking lock status. For buyers already using either ecosystem, the setup process is straightforward enough.
The integration depth is limited — you won't find the kind of automation routines or third-party app support that premium brands offer. Users trying to build more complex smart home workflows around this lock frequently hit a ceiling with what the TTLock skill can actually do.
Included Accessories
84%
Five IC cards and two physical backup keys included in the box is genuinely generous for this price tier. Multi-user households and small rental operations can get up and running without immediately buying extra accessories.
Batteries being excluded is a recurring complaint — it's a small but unnecessary friction point on unboxing day. Some buyers also note that the mounting hardware feels lightweight compared to what premium lock kits provide.
Weather Resistance
63%
37%
The lock is listed as weather resistant and handles light rain and humidity reasonably well based on buyer reports from temperate climates. The backlit keypad remains readable in low-light outdoor conditions, which is a practical plus for exterior installation.
Buyers in regions with harsh winters or sustained wet seasons report more frequent fingerprint read failures and some cosmetic degradation over time. The weather resistance rating is not formally certified to any published IP standard, which makes it harder to assess objectively.
Customer Support
54%
46%
Some buyers report resolving basic setup questions quickly through the brand's support channels, and third-party TTLock communities online fill some of the gap for common troubleshooting scenarios.
Response times from CATCHFACE's official support are inconsistent, with a meaningful number of buyers describing multi-day waits or unhelpful replies for anything beyond basic questions. Firmware update communication is also sparse, leaving users uncertain about whether their lock is running current software.

Suitable for:

The CATCHFACE B17 Smart Fingerprint Keyless Entry Lock is a genuinely practical choice for short-term rental hosts who need to manage guest access remotely without being on-site for every check-in. If you run an Airbnb or VRBO property, the ability to issue time-limited virtual keys and pull up access logs from your phone covers most of what you actually need at a price that doesn't eat into your margins. Apartment renters who want keyless convenience but can't justify the cost of a premium brand will also find this a reasonable fit — installation takes roughly 20 minutes and doesn't require a locksmith. Small office managers who want a basic record of who entered and when will appreciate the time attendance feature without having to pay for a commercial access control system. DIY-confident buyers who are comfortable downloading an app, following instructions, and doing their own setup will get the most out of what this lock offers.

Not suitable for:

The CATCHFACE B17 Smart Fingerprint Keyless Entry Lock is probably not the right call if truly hands-off remote access is your top priority — the lock runs on Bluetooth by default, and unlocking it from anywhere requires buying a separate Wi-Fi gateway that isn't included in the box. Buyers who expect a plug-and-play experience with zero app setup will likely find the TTLock platform frustrating, especially if they're not comfortable navigating settings menus. Anyone living in an extremely cold climate or who frequently has wet hands should know that fingerprint sensors in this price range can be inconsistent under those conditions. If you're security-conscious and accustomed to the build quality of brands like Schlage or August, the zinc alloy housing may feel lighter and less robust than you'd like. Finally, buyers who anticipate needing fast, reliable manufacturer support should factor in that customer service responsiveness for smaller brands like this one can be hit or miss.

FAQ

Not exactly — the CATCHFACE B17 Smart Fingerprint Keyless Entry Lock connects to your phone over Bluetooth out of the box, which means you need to be within Bluetooth range to control it through the app. If you want true remote access from anywhere, you'll need to buy the Wi-Fi gateway separately. It's a common surprise for buyers, so it's worth factoring that into your budget upfront.

Most people manage the installation themselves in around 20 minutes using a screwdriver and a drill. The lock replaces your existing door handle and deadbolt assembly, and the included instructions walk you through the process step by step. No locksmith required, though it helps to be comfortable with basic home hardware tasks.

It's designed for standard residential doors with a 2.125″ bore hole, a thickness between 1.37″ and 1.88″, and a backset between 2.375″ and 2.75″. That covers most apartment and home doors in North America. Just measure your existing door before ordering to be sure.

Yes, absolutely. The fingerprint sensor, keypad PIN, IC cards, and physical backup keys all work independently of your phone. The app adds scheduling and remote management, but it's not required for day-to-day entry.

The TTLock platform supports storing multiple fingerprints and PIN codes, which is practical for households or rental properties with several users. The exact storage capacity can vary by firmware version, so checking the TTLock app settings after setup will give you the precise current limits.

Two physical backup keys are included in the box specifically for this situation. Most smart locks in this category also have a low-battery alert that gives you advance warning through the app before power is fully depleted, so you typically have time to swap batteries before things get urgent.

Fingerprint sensors at this price point can struggle a bit when your fingers are wet, sweaty, or very cold. It's not a dealbreaker for most users, but if you live somewhere with harsh winters or plan to use this on an exterior door in wet conditions, keep a PIN or IC card as your go-to backup method.

Yes, that's one of the more useful features here. Through the TTLock app, you can create virtual keys for specific people and set them to expire after a certain date or time window. This is particularly handy for Airbnb hosts or anyone who needs to let someone in temporarily without changing their main access credentials afterward.

It does support both Amazon Alexa and Google Assistant, so you can use voice commands for basic functions. The depth of integration depends on how the TTLock skill is set up in your smart home app, but locking and status checks are generally covered.

It's manageable, but it does have a bit of a learning curve. Pairing the lock, setting up users, and configuring schedules all require navigating through several menus. Most users get comfortable with it after a session or two. If you're setting it up for a family member who's not great with apps, plan to walk them through it in person the first time.
