Evanshow Fingerprint Door Lock Biometric Doorknob — Silver keyless entry, keypad & card, fits interior doors

The Evanshow Fingerprint Door Lock is a keyless biometric doorknob combining fingerprint, keypad, card and mechanical key options for fast, secure access.

This smart doorknob replaces traditional locks with a compact, battery-powered unit that fits most interior doors. It stores multiple fingerprints and temporary codes, offers a USB emergency power point, and installs without wiring or major carpentry. The lock is optimized for bedrooms, apartments, hotel rooms and offices where simple, flexible access control matters.

How quickly and accurately does the fingerprint reader work?

The upgraded sensor captures prints in roughly half a second and reduces mistaken rejections for smoother entry. It uses a reliable recognition algorithm to match stored templates, making daily use quick and friction-free.

• 0.5s typical fingerprint recognition time
• High-precision sensor minimizes false rejections
• Supports up to 100 fingerprint templates for family or staff

What access methods are available and how many users can it support?

This unit is a 4-in-1 access system: biometric fingerprint, numeric keypad, IC cards and two mechanical keys. You can program multiple users and temporary codes so guests and service personnel have controlled access.

• Stores up to 100 fingerprints
• Accepts up to 50 distinct password codes
• Includes two physical mechanical keys and supports up to 4 IC cards

Is the lock difficult to install or maintain?

Installation is designed for DIY: no drilling beyond standard latch holes and no wiring is required. The package includes tools and tutorial videos; batteries power the unit and a USB port allows emergency external power if batteries die.

• Fits wooden doors 1.18"–1.97" thick and both left/right swings
• Quick, tool-based installation with video guidance
• USB emergency power input (does not charge internal batteries)

How does the lock handle security and administrator setup?

Before first use you must register an administrator fingerprint; until that admin record exists, any enrolled fingerprint can unlock the door. Proper initial setup prevents unauthorized enrollment and lets you manage users and temporary credentials.

• Administrator fingerprint required for secure setup
• User management for adding or deleting credentials
• Mechanical keys provide a backup override option

Who is this for: The Evanshow Fingerprint Door Lock is for homeowners, renters, small offices, guest suites and short-stay properties that need flexible, keyless access without rewiring. It fits users who want fast biometric entry, multiple credential options, and straightforward DIY installation with practical backup choices.
