The Sifely Keyless Entry Fingerprint Smart Door Lock is a lever-style smart lock designed to retrofit standard residential doors without drilling. It offers five to six unlock methods including fingerprint, keypad, key cards, fobs, and physical keys, with optional remote access via a separate Wi-Fi gateway. It is best suited for indoor or sheltered exterior doors and multi-user households.

The Yamiry Smart Door Handle Lock (YR01) is a 5-in-1 keyless entry smart knob designed for DIY installation without extra drilling. It supports multiple unlock methods including fingerprint, keypad, IC cards, smartphone app via Bluetooth, and mechanical keys. The main trade-off is the lack of native Wi-Fi connectivity and potential installation difficulties regarding latch alignment.

Products in the top-left offer the best value (high score, low price).

Professional reviewers position the Sifely keyless fingerprint lock as a budget-friendly, easy-install option with strong suitability for indoor, family, and light exterior use. They caution against relying on it in consistently harsh outdoor conditions or for users with very high-moisture or dirt-prone environments, noting that fingerprint reliability under wet conditions is less stable than higher-end competitors.
Everyday users tend to rate this lock highly for interior use and protected entry doors, praising its ease of installation and value for money. The main caveats reported by consumers are conditional grip on fingerprint recognition when hands are wet or dirty, and the need for a gateway to enable full remote features.

No independent professional reviews from major tech outlets were found in the available data. The manufacturer and support pages emphasize the product's ease of installation, diverse access methods, and family-friendly fingerprint capabilities, while addressing common setup issues like latch alignment and app pairing.
Everyday users generally praise the convenience of multiple keyless entry methods and the reliability of the fingerprint scanner for older kids.
