Yamiry’s fingerprint keypad smart door knob lock is built for buyers who want keyless entry without replacing an entire door system.
If you are comparing a Keypad Smart Door Knob Lock review against simpler mechanical hardware, this one stands out for its multiple unlock paths and straightforward retrofit pitch.
Yamiry Fingerprint Knob Lock Review Summary
This Keypad Smart Door Knob Lock review comes down to fit, flexibility, and convenience.
It is a strong choice for homeowners who want a smart handle-style lock with fingerprint access, keypad entry, and app-based control, especially when they want a relatively simple install and do not want to abandon a traditional deadbolt setup.
The biggest advantage is versatility.
The listing says the lock supports app, password, key fob, fingerprint, and key access, plus auto lock and app lock.
That makes it a practical option for families, rental turnovers, side doors, or anyone who wants multiple fallback methods instead of relying on one credential type.
Review Scorecard
| Category | Score | Why it matters |
|---|---|---|
| Access flexibility | 9/10 | Five unlock methods and three lock methods reduce lockout risk and improve everyday convenience. |
| Installation ease | 8/10 | The listing says it can be installed with just a screwdriver on compatible standard doors. |
| Smart features | 8/10 | Bluetooth app control is built in, with remote control available through a separate Wi-Fi gateway. |
| Security basics | 7/10 | Aluminum construction and auto-lock help, but it is still a knob lock paired with an existing deadbolt. |
| Family convenience | 9/10 | Fingerprint, keypad, and key fob support make it easy for different users to enter quickly. |
| Long-term support | 8/10 | The product page mentions a 30-day money-back guarantee, 1-year coverage, and lifetime after-sales support. |

It is best for buyers who value convenience and layered access more than premium hardware specs.
Key Features and Specifications of Yamiry Fingerprint Knob Lock
The listing describes this as an aluminum smart door knob lock designed for American standard doors.
That matters because the product is not trying to be a universal, heavily customized system; it is pitched as a practical retrofit for common residential doors.
The standout feature set is access variety.
The lock supports app, password, key fob, fingerprint, and key unlock methods.
For locking, it offers auto lock, app lock, and a long-press button lock option.
In real-world use, that means you can choose the method that fits the moment instead of forcing every user into the same routine.
Another important detail is the stored credential capacity.
The listing says the lock can store 50 passwords and fingerprints and key fobs via Bluetooth.
That is useful for households with multiple family members, temporary guests, or recurring service access.
The smart side is split into local and remote control.
Bluetooth app control is included, while remote access requires a Wi-Fi gateway sold separately.
That is a fair tradeoff if you want the base product to stay simpler and only add remote control if you truly need it.
| Feature | What the listing says |
|---|---|
| Material | Aluminum |
| Door compatibility | Most American standard doors |
| Installation | Easy installation with just a screwdriver |
| Unlock methods | App, password, key fob, fingerprint, key |
| Lock methods | Auto lock, app lock, long-press button lock |
| Credential storage | 50 passwords, fingerprints, and key fobs |
| Connectivity | Bluetooth; remote control with separate Wi-Fi gateway |
| Support | 30-day money-back guarantee, 1-year coverage, lifetime after-sales support |
The included key access also matters.
Even when buyers move toward app-based entry, many still want a physical fallback for peace of mind.
This product keeps that option in the mix rather than making the smart system the only route.
Pros and Cons of Yamiry Fingerprint Knob Lock
Pros
- Multiple unlock methods make daily use more forgiving.
- Fingerprint entry should be faster than typing a code in routine use.
- Auto lock is useful for households that often forget to secure the door.
- Bluetooth control keeps the base setup simple.
- Remote control is available if you add the separate gateway later.
- The aluminum construction and corrosion resistance claim suggest a durable material choice.
Cons
- Remote access is not included out of the box.
- It is a knob lock, so it is best thought of as part of a door setup rather than a standalone heavy-duty deadbolt replacement.
- Buyers who want fully integrated smart-home control may find the separate gateway requirement limiting.
- The listing emphasizes compatibility, but buyers still need to confirm fit for their exact door before ordering.
The pros are strongest when the buyer wants convenience first.
The cons matter more if the project is about upgrading an entryway for broader smart-home automation or more advanced security hardware.
Who Should Buy Yamiry Fingerprint Knob Lock?
This Keypad Smart Door Knob Lock is a good fit for families, shared households, and homeowners who want faster entry without carrying keys all the time.
It also makes sense for buyers who like the idea of fingerprint access but still want password, key fob, and physical key backup.
It is especially attractive for doors that already use a deadbolt and need a smart knob-style companion.
In that scenario, the product’s value is in convenience and access management, not in replacing every layer of the entry system.
Buy it if you want easy day-to-day access, flexible user options, and a straightforward install on a compatible door.
Skip it if you want a fully remote-first lock on day one, a premium standalone deadbolt, or the most minimal possible hardware setup.
How the Yamiry Fingerprint Knob Lock Works in Daily Use
Fingerprint and Code Entry
Fingerprint access is the most natural fit here because it removes the extra step of remembering a code.
For families, that means fewer shared passwords and fewer reasons to leave a key in circulation.
App and Fob Control
The app and key fob options are useful for different user habits.
App control suits the primary homeowner, while a fob can be easier for kids, older relatives, or anyone who does not want to manage a smartphone-based workflow.
Auto Lock Behavior
Auto lock is the feature that protects against forgetfulness.
It will not matter to every buyer every day, but for busy entries and exits it can be the difference between a door staying secured and a door being left in a rushed state.
Compatibility and Setup
The listing says installation is easy with a screwdriver and that the lock works with most American standard doors.
That makes the product easier to justify for buyers who want a practical upgrade rather than a major hardware project.
Alternatives to Yamiry Fingerprint Knob Lock
If you want a different style or ecosystem, a few Amazon search alternatives are worth comparing:
- Schlage Encode Smart WiFi Deadbolt
- Kwikset SmartCode Keypad Deadbolt
- Yale Assure Lock
- Defiant Electronic Keypad Door Lock
These are credible alternatives if you want a deadbolt-first format, a different smart-lock ecosystem, or a simpler keypad-only approach.
Compare them based on whether you need a knob lock, a deadbolt, fingerprint entry, or deeper smart-home integration.
Is Yamiry Fingerprint Knob Lock Worth It?
Yes, if your goal is flexible keyless entry on a compatible standard door and you want several backup methods in one lock.
The combination of fingerprint, code, app, fob, and key access makes it appealing for households that need convenience without giving up redundancy.
It is less compelling if you want a remote-first setup without extra accessories, or if you are shopping for the most security-focused deadbolt on the market.
But for the buyer who wants a practical smart knob with broad access options, the Yamiry fingerprint keypad smart door knob lock is worth serious consideration.
