Who it fits
Good fit for
You should consider this knob if you want keyless entry with fast access. The 0.1-second recognition is ideal for busy households. The local storage appeals to users prioritizing privacy over cloud features. The 100-fingerprint capacity suits families or small offices. The 5-second auto-lock provides security without waiting. It fits standard doors and installs in 15 minutes. The sweat-proof design handles outdoor use well.
Who should skip it
Skip this option if you need remote guest access via temporary codes, as the app focuses on local management and records. The 5-second auto-lock may feel too fast for some users who prefer longer windows. If you require integration with broader smart home ecosystems beyond TT LOCK, this standalone unit may not fit. Users needing a keypad for code entry will find it lacking. The physical key backup is included, but no keypad exists.
Verdict: The EUERTE S10T offers fast, local biometric security for users who value privacy and simplicity. It is a solid choice for standard doors requiring quick, keyless access.
Key specs explained for this lock
Recognition Speed: 0.1s
This spec indicates the sensor identifies your print in one-tenth of a second. You can enter without pausing or looking at the device. This speed reduces wait times for you and guests. It matches the rapid access found in many top-tier smart locks. Fast recognition ensures smooth daily entry for busy households.
Fingerprint Capacity: 100
The device stores up to 100 unique fingerprints. This limit suits families with multiple members or rental properties with rotating tenants. You can assign prints to adults and older children. This capacity is standard for residential smart locks. It avoids the need for frequent memory management in most homes.
Auto-Lock Delay: 5s
The lock engages automatically five seconds after the door closes. This feature prevents you from forgetting to turn the deadbolt manually. It ensures the door is secure even if you rush out. This delay is quick enough for normal traffic but slow enough to allow exit. It adds passive security without extra effort.
Access Methods: Fingerprint, app, physical key
You can unlock the door using your print, the TT Lock app, or a physical key. This variety provides backup options if batteries die or the app fails. The app allows remote management for renters or hosts. Physical keys offer a reliable fallback. This combination covers most access scenarios for home security.
Design and build quality
The listing describes the EUERTE S10T as having a sturdy zinc alloy construction with a premium metallic finish. It measures 9.29 inches in length and 3.29 inches in both width and height. The unit weighs 1.72 pounds. This solid build suggests it can withstand regular use in high-traffic areas like offices or dormitories. The sweat-proof and weatherproof design indicates it remains durable even with wet hands or outdoor exposure. You do not need to worry about corrosion from daily handling.
The layout centers on a single door knob control. It includes a 360-degree fingerprint sensor for quick access. You can also use the TT LOCK app for remote management or physical keys for backup. The black color option blends with most standard door styles. The compact dimensions ensure it fits standard door preparations without requiring major modifications. Installation requires only a screwdriver and takes less than 15 minutes according to the listing.

Setup and everyday use guide
You can install this lock using only a screwdriver. The process takes less than 15 minutes. The package includes the knob hardware, so you do not need to buy extra parts for basic mounting. This straightforward setup allows you to secure your door quickly without professional help.
For daily operation, you have three access methods. You can use the 360-degree fingerprint sensor, the TT LOCK app, or physical keys. The sensor recognizes prints in 0.1 seconds. This speed means you enter without pausing. The system stores up to 100 fingerprints locally. This local storage keeps your data private and does not require cloud uploading. You can add or remove users directly through the app.
The app also lets you manage settings. You can set the auto-lock delay to 5 seconds. This feature ensures the door secures itself shortly after you enter. You can also enable passage mode for temporary unrestricted access or privacy mode to block entry from the outside. The app displays unlock records and battery capacity. This transparency helps you monitor usage and maintenance needs.
The zinc alloy construction and metallic finish are designed for durability. The sweat-proof design handles wet hands or outdoor exposure. This makes it suitable for high-traffic areas like bedrooms, offices, or rentals. You get reliable access without complex maintenance routines. The physical key remains a backup option if the battery dies or the app is unavailable.
Check Compatibility Before Buying
Before purchasing the EUERTE S10T fingerprint smart door knob, verify your door’s backset and thickness. This lock requires a standard deadbolt hole for the physical key override. Check that your smartphone supports the TT LOCK app. The device stores data locally, so you do not need cloud connectivity for basic fingerprint access. However, app features like remote logs require your phone to be paired via Bluetooth. Clean the sensor regularly with a dry cloth to maintain its 0.1-second recognition speed. Avoid harsh chemicals that might damage the zinc alloy finish. This lock suits renters or homeowners seeking quick entry without a keypad. It fits well in homes where you already use video doorbells for visitor monitoring. Unlike smart locks with screens, this unit relies on your phone or finger. Ensure your door swings inward or outward correctly, as the auto-lock engages after five seconds. This model is ideal for bedrooms, offices, or Airbnb rentals where you need simple, reliable access control without complex wiring.
Check before you buy
- Verify door thickness and backset dimensions match the lock requirements.
- Confirm your smartphone supports the TT LOCK app for remote features.
- Ensure the door has a standard deadbolt hole for key override.
- Check if your door swings correctly for the five-second auto-lock.
