Yamiry Smart Deadbolt Door Lock with Keypad combines fingerprint recognition, electronic code entry, and traditional key access in a single unit built for front door security. The exterior is constructed from zinc alloy with a brushed black finish, providing resistance against corrosion and physical impact. A capacitive semiconductor fingerprint sensor rests beneath the touchpad, offering quick and accurate scanning for registered users. The keypad itself uses backlit numeric buttons, ensuring visibility in low light while maintaining a clean, modern appearance.

Internal components include a durable stainless steel latch bolt and a quiet motor mechanism that retracts the bolt smoothly upon correct authentication. This electronic deadbolt supports up to 50 user codes and 30 fingerprint profiles, making it suitable for family members, guests, or service providers without needing physical keys. Each credential type can be individually managed and deleted, giving the homeowner full control over access permissions. The lock also preserves a history of the last 20 unlock events, record which method was used and at what time, though this log is only accessible via the built-in interface.

Battery operation relies on 4 AA cells (not included), with a low-battery warning indicated by both audible beeps and a flashing light on the keypad. In case of complete power loss, the mechanical key override remains functional, ensuring entry is never blocked. Installation is designed for do-it-yourself completion on standard residential doors (1.38 to 1.97 inches thick, both left‑ and right‑hand hinge orientations). The package includes a mounting plate, screws, and a detailed manual; no additional drilling or wiring is required if the existing deadbolt hole is at the correct distance.

The entire assembly weighs approximately 2.5 pounds and takes under 20 minutes to fit with basic tools. Construction quality focuses on long-term reliability: the fingerprint sensor is rated for over 100, 000 touches, and the motor has been tested for 200, 000 cycles under normal conditions. The exterior shell is IP65 rated, meaning it is resistant to rain and dust ingress, though the interior unit should remain in a dry environment. At a price point of around $89, this smart deadbolt delivers solid build standards and essential keyless features without the cost of more advanced Wi‑Fi or Z‑Wave models.

It is an affordable upgrade for homeowners seeking to eliminate fumbling for keys while retaining a straightforward, physical backup option. The combination of biometric, code, and key access covers everyday use and emergency scenarios evenly. Given its material durability, installation simplicity, and maintenance‑free operation (battery changes aside), the Yamiry deadbolt represents a practical, value‑oriented choice for enhancing entryway convenience and security.
