Who it fits
Good fit for
This lock suits renters or homeowners who want keyless entry without managing a smartphone app. It is ideal for households with multiple members, given the 100-fingerprint capacity. The 0.5-second recognition speed benefits busy mornings. It works well for bedrooms, offices, or apartments where simple, reliable access is key. If you prefer physical keys or passcodes over digital management, this spec-focused knob fits your setup.
Who should skip it
You should look elsewhere if you need remote access or activity logs. This device lacks Wi-Fi connectivity and a companion app. You cannot unlock it or check status from your phone. It also does not support smart home integrations. If you want to grant temporary access to guests via an app or receive alerts when someone enters, this hardware will not meet your needs. It is strictly a local access solution.
Verdict: This is a simple, spec-driven lock for users who value speed and capacity over smart features. It delivers fast, local access without the complexity of app management.
Key specs explained for this lock
Access Methods: Fingerprint, password, key, IC card
You get four ways to enter. The system supports fingerprints, a numeric password, two physical keys, and IC cards. This variety helps if you forget your code or lose a card. The physical keys are a crucial backup if the electronics fail. You can mix these methods for different family members. This multi-option approach offers flexibility that single-method locks do not provide.
Recognition Speed: 0.5s
The scanner reads your print in half a second. This speed reduces wait times when you are holding groceries or rushing out. It also minimizes the chance of the door rejecting your print due to slow movement. Fast recognition improves the daily user experience significantly. You should compare this speed against other biometric locks to ensure it meets your needs for efficiency.
Fingerprint Capacity: Up to 100
You can register up to one hundred unique fingerprints. This capacity suits larger households or shared office spaces. It allows you to include all family members and frequent guests without deleting old entries. You do not need to manage storage space for new users. This limit ensures the lock remains useful as your household or team grows over time.
Passcode Capacity: 50
The keypad stores fifty distinct numeric passwords. You can assign unique codes to different people or use temporary codes for visitors. This number balances security with convenience. You have enough slots for regular users without filling the memory quickly. It is important to check this limit against other smart locks to ensure it meets your access management requirements.
Physical Build and Design Details
According to the listing, the Evanshow Keypad and Biometric Door Knob is a silver unit that functions as a standalone handle rather than a connected device. It lacks an app, meaning you cannot control it remotely or monitor activity from a phone. This design choice keeps the focus entirely on physical entry. The finish is a uniform silver, which complements standard interior and exterior door hardware without requiring a matching smart home ecosystem.
The physical dimensions are compact, measuring two inches in width and height, with a one-inch length. It weighs 1.2 pounds, providing a solid feel when you turn the knob. The device fits wooden doors between 1.18 and 1.97 inches thick, accommodating most standard residential doors. It supports both left and right swing configurations, ensuring flexibility during installation. The package includes the knob hardware, so you do not need to purchase additional components separately.
Controls are integrated directly into the knob. You use a keypad for passwords and a fingerprint scanner for biometric access. The scanner is positioned for easy reach, recognizing prints in 0.5 seconds. This speed reduces wait time when entering your home. The layout is simple, with no complex menus or digital displays to navigate. You rely on the physical keys and IC cards as backups, which are stored in the lock’s mechanism. This straightforward design suits users who prefer direct interaction over smartphone management.
Setup Process and Daily Operation
Initial configuration requires strict adherence to the manufacturer’s instructions. You must register at least one administrator fingerprint before the lock becomes secure. Until this step is complete, any stored or new fingerprint will unlock the door. This creates a temporary vulnerability during the first few minutes of installation. Once the admin profile is active, the system restricts access to authorized users only.
Installation is designed for standard wooden doors ranging from 1.18 to 1.97 inches thick. The unit supports both left and right swinging doors. You can install the handle without drilling or wiring, using the included tools and video tutorials. The process typically takes only a few minutes. No professional assistance is required for this mechanical setup.
Daily use relies on the four access methods: fingerprint, password, key, or IC card. The sensor recognizes fingerprints in 0.5 seconds, allowing for quick entry. You can store up to 100 fingerprints and 50 passwords. This capacity suits families with multiple members or guests who need temporary codes. The lock also includes two physical mechanical keys for backup access.
Power management involves internal batteries and a USB port for emergency situations. You can connect an external power bank to the USB port if the batteries die. This port does not charge the internal batteries. It only provides temporary power to operate the lock. The lack of an app means you cannot monitor activity remotely. All management happens directly at the knob.
Before You Buy This Lock
You should verify your door thickness before purchasing. The listing states it fits wooden doors between 1.18 and 1.97 inches thick. If your door is outside this range, this handle will not work. You also need to check if your door swings left or right, as the unit is designed for specific orientations. Since there is no app, you cannot monitor entry remotely. This makes it a simple physical lock rather than a connected smart device. It pairs well with video doorbells for full security coverage. You will need to replace batteries periodically. The USB port is for emergency power only and does not charge the internal batteries. Keep the two mechanical keys in a safe place. Do not rely solely on fingerprints, as they can fail if your fingers are wet or dirty. This lock suits users who want easy keyless entry without complex setup.
Check before you buy
- Confirm door thickness is between 1.18 and 1.97 inches.
- Check if your door swings left or right.
- Ensure you have space for a standalone handle.
- Keep mechanical keys in a secure location.
- Verify you do not need remote app control.
