AI Verdict
This is a Bluetooth-controlled fingerprint doorknob with keypad and key access, best for interior doors needing basic smart access.
This doorknob is a strong fit for interior doors where a deadbolt isn't typically used, offering convenient fingerprint and keypad access with local data storage. Its Bluetooth-only app control means it's less suited for primary entry points needing true remote management without an additional gateway.
If you need full remote Wi-Fi access and more robust security for an exterior door, look for a smart deadbolt with integrated Wi-Fi.

Pros
- Unlocks via fingerprint, keypad, app (Bluetooth range), or mechanical key.
- Fingerprint recognition is fast at 0.2 seconds with 99.9% accuracy.
- Stores fingerprint data and app data locally, not in the cloud, for privacy.
- Rechargeable 400mAh battery lasts for 10,000 unlocks or 300+ days on a 4-6 hour charge.
- Includes a USB-C port for emergency power if the battery dies.
- Supports 20 unique fingerprints and 20 personalized access codes.
Cons
- App control is limited to Bluetooth range; remote unlocking requires an additional gateway.
- The exterior knob is 2.5 inches in diameter, which is larger than typical 2-inch doorknobs.
- Keypad placement on a doorknob can feel awkward to use, requiring a lean back for a clear view.
- The app (Gosund or GHome Smart) may lack deep settings options.
- Batteries are built-in and rechargeable, meaning no quick swap of AAAs if it dies unexpectedly.
Dimension Scores
The lock boasts 0.2-second fingerprint recognition with 99.9% accuracy, and users report fast, smooth recognition.
Connectivity is limited to Bluetooth, requiring an additional gateway for remote Wi-Fi access, which restricts its utility for true remote management.
The app allows management of fingerprints, passwords, access logs, and modes, but some users note a lack of deep settings and it requires a separate gateway for full smart home integration.
Constructed from aluminum and designed for easy installation, but its doorknob form factor and lack of specific weather resistance ratings suggest it's primarily for interior use.
Best For
- Securing interior doors like bedrooms, home offices, or storage rooms.
- Apartment dwellers or Airbnb hosts needing temporary access codes for guests.
- Users prioritizing local data storage for biometric information.
Not Recommended For
- Main entry doors requiring robust security or Wi-Fi remote access without an extra gateway.
- Users who prefer traditional deadbolt security over a doorknob form factor.
- Anyone needing extensive smart home integration without purchasing additional hardware.
Watch Out For
- The app only works within Bluetooth range, so you can't unlock it remotely from outside your home without buying a separate Bluetooth gateway.
- The exterior knob's 2.5-inch diameter might feel bulky or look out of place compared to standard 2-inch doorknobs.
- Using the keypad can be awkward because of its position on a doorknob, potentially requiring you to lean back to see the numbers clearly.
- While the battery lasts 300+ days, it's a built-in rechargeable unit, so if it dies, you'll need to use the physical key or a power bank with the USB-C port for emergency access.

What Buyers Say
Many users found the GHome Smart Fingerprint Door Lock surprisingly functional for its price, especially for interior doors. The quick fingerprint recognition and multiple unlock methods were frequently highlighted as convenient. However, the Bluetooth-only app control without an included gateway was a recurring point of frustration for those expecting full remote access. The large size of the exterior knob and the awkwardness of using the keypad on a doorknob were also noted by some.
“Honestly, for my bedroom door, this thing is perfect. Fingerprint works every time, and I don't have to carry a key. Just wish I could unlock it from work, but hey, it's cheap!.”
Common Praise
- Fingerprint recognition is quick and accurate, allowing instant access.
- Multiple unlocking options (fingerprint, keypad, app, key) provide flexibility.
- Installation is straightforward and can be done with just a screwdriver.
- Local storage of biometric data offers peace of mind regarding privacy.
- The auto-lock feature ensures the door is secured after 5 seconds.
Common Complaints
- Requires a separate gateway for remote Wi-Fi control, which isn't clearly advertised as an extra purchase.
- The keypad on the doorknob can be difficult to use, especially for taller individuals.
- The exterior knob's 2.5-inch diameter is noticeably larger than typical doorknobs.
- The built-in rechargeable battery, while long-lasting, means no quick battery swaps if it dies.
- App functionality is limited when not within Bluetooth range.
Ownership Tips
- The battery indicator in the app is crucial for knowing when to charge, as there's no external warning light.
- Setting up temporary codes for house sitters or guests is super easy through the app.
- The physical keys are a lifesaver if you forget to charge it or the electronics glitch out.
- The 'privacy mode' is actually useful for keeping kids out of certain rooms, disabling all but admin access.
Frequently Asked Questions
Does this lock connect to Wi-Fi for remote access?
No, the lock connects via Bluetooth to your phone for app control within range. For remote unlocking and smart home integration outside of Bluetooth range, you need to purchase a separate GHome Smart Tuya Bluetooth Gateway.
How many fingerprints and passcodes can it store?
The lock can store up to 20 unique fingerprints and 20 personalized access codes.
What happens if the battery dies?
If the 400mAh rechargeable battery runs out, you can use one of the two included mechanical keys for emergency access, or connect a power bank via the USB-C port to temporarily power the lock.
Is my fingerprint data stored in the cloud?
No, all fingerprint data is stored 100% locally on the device, ensuring enhanced privacy and security.
Can I set temporary access codes for guests?
Yes, you can generate temporary access codes through the app, which can be set with specific effective times and dates.
Buying Guide
When looking at smart doorknobs like this, you need to think about where it's going. Is it for an interior door where you want convenience, or an exterior door where you need serious security and remote access? This type of lock is usually better for the former, as its form factor isn't as robust as a deadbolt, and its smart features are often Bluetooth-limited unless you buy more gear.
lock_type: Fingerprint, Key Lock, Keypad Lock
This tells you all the ways you can get in. Fingerprint is fast, keypad is good for guests, and the physical key is your backup if everything else fails, like having a spare house key under the mat.
wifi: Bluetooth
Bluetooth means your phone needs to be close to the lock to control it with the app, similar to how your car's Bluetooth connects to your phone only when you're inside the car. If you want to unlock it from across town, you'll need an extra Wi-Fi bridge.
special_feature: Auto-Lock
This feature automatically locks the door after a set time (like 5 seconds here), so you don't have to remember to turn the knob. It's like your car doors automatically locking once you start driving.
Alternatives
If you need full remote control from anywhere or a more secure option for an exterior door, look for smart deadbolts with integrated Wi-Fi and a higher security rating.
