According to the source review from Tom's Guide, the Lockin Veno Solar smart lock distinguishes itself by using a solar panel to keep its battery charged indefinitely, eliminating the need for manual battery replacement or recharging. The review focuses on the Face model and highlights its integration with Matter and multiple unlocking methods, although the face recognition speed is somewhat slower than advertised.
- Solar-powered battery charging eliminates recharging or replacements
- Supports facial or palm vein recognition, PIN, app, voice, and key access
- Priced from $199; integrates with Matter and standard smart home systems
Product angle
The source review from Tom's Guide reports that the Lockin Veno Solar smart lock uses an integrated solar panel to continuously charge its battery, effectively removing the need for periodic battery changes or manual recharging. This design innovation addresses a common pain point of smart locks, which typically require annual battery maintenance. The lock offers two variants differing in biometric access: facial recognition or palm vein scanning, with the Face model undergoing evaluation.
In addition to biometric options, the Lockin Veno Solar supports unlocking via PIN codes, a smartphone app, voice assistant commands, and even a mechanical key backup. Its connectivity includes Wi-Fi, Bluetooth, and Thread protocols, and it is compatible with the Matter smart home standard, making it a flexible option for users seeking seamless smart home integration. Installation replaces the existing lock hardware completely and takes about 15-20 minutes.
Best for / avoid if
This smart lock is best suited for tech-savvy homeowners who prioritize low maintenance and want a smart lock solution that does not require regular battery upkeep. Its solar charging capability suits outdoor use in locations with sufficient sunlight exposure. Its inclusion of facial or palm vein biometric unlocking makes it appealing for users seeking advanced security features paired with modern authentication methods.
Potential buyers should avoid this lock if they live in environments with minimal sun exposure or harsh weather conditions, as its IP53 rating offers only limited water resistance. Additionally, users expecting near-instant facial recognition may find the unlocking speed slightly slower than claimed, which could be a drawback for those prioritizing rapid access. The requirement to fully replace existing lock components might also discourage renters or those seeking simple retrofit options.
Pricing and alternatives to check
The Lockin Veno Solar smart lock series launched in mid-2026, with pricing starting at $199 for the standalone lock and $259.99 for packages that include a door handle. It is available directly through Lockin's website and Amazon, providing convenient purchase options. This price point is competitive within the smart lock sector, especially given the solar charging feature and integration with modern smart home protocols like Matter.
Buyers interested in alternatives may want to explore other smart locks with longer battery lives but without solar charging, or models with higher weather ratings for greater durability. Common alternatives include locks from brands reputed for their extensive smart home ecosystem support and strong physical build quality. Those prioritizing retrofit ease may consider smart locks designed for compatibility with existing deadbolts rather than complete lock replacement.
