Works With
The eufy Smart Lock E330 is a good choice for users wanting biometric access and voice assistant integration but may frustrate those seeking flawless app performance or strong WiFi reliability.
The eufy Smart Lock E330 with Chime WiFi Replacement Deadbolt offers a solid mix of biometric access, keypad entry, and app control, making it versatile for various home security needs. Its fingerprint sensor is responsive and generally accurate, which is a strong point compared to many competitors that rely solely on keypad or app access. The included chime is a nice touch for alerting you when the door is used. Integration with Amazon Alexa and Google Home works well, allowing for voice commands and automation. However, the lock is priced at $269.99, which is on the higher side for smart locks that don’t include a hub. Battery life typically lasts around 6-8 months on standard AA batteries, but users report that the lock’s app can be sluggish and occasionally unresponsive, which can be frustrating. The keypad is backlit but not very bright, making nighttime use a bit tricky. Installation is straightforward for those comfortable with basic tools, but the lock’s WiFi connection can be temperamental in homes with weak signals. This lock is ideal for tech-savvy users who want biometric access and easy integration with voice assistants. Those on a tighter budget or who want a simpler setup might prefer the August Wi-Fi Smart Lock or the Schlage Encode, which offer more consistent app performance. Users seeking a lock with a longer battery life or more robust app experience might want to look elsewhere.

Stay connected with real-time notifications on your phone, showing who's coming and going as all door activities are logged in the event history for your review.
Connectivity
Full feature set requires WiFi connection; no Apple HomeKit support limits iOS ecosystem integration.
Compared to the August Wi-Fi Smart Lock, the eufy E330 offers biometric access, which August lacks, but August’s app is generally more polished and reliable. The Schlage Encode provides a sturdier build and a brighter keypad but doesn’t have biometric features and costs around the same price. The Yale Assure Lock SL is another competitor with a sleek touchscreen keypad but requires a separate hub for WiFi, unlike the eufy which connects directly. Each has trade-offs between biometric convenience, app reliability, and installation complexity.
Installation rates around a 3 out of 5 in difficulty. It typically takes 20-30 minutes with a screwdriver and possibly a drill if your door isn’t prepped. The instructions are clear but some users find aligning the biometric sensor tricky. No professional installation is necessary unless you’re uncomfortable with door hardware. WiFi setup can be fiddly if your router signal is weak near the door.
Daily use is generally smooth, with fingerprint recognition responding in under a second. The app allows remote locking/unlocking but can lag or fail to update status promptly. Battery life usually lasts 6-8 months, which is decent but not exceptional. Users occasionally report connectivity drops, especially in larger homes with spotty WiFi. The chime feature works reliably, adding a useful notification when the door is accessed.
- App responsiveness can be slow or occasionally unresponsive
- WiFi connection drops in homes with weak signals
- Keypad backlight is dim and hard to see at night
- Fingerprint sensor sometimes requires multiple attempts
- Battery life shorter than some competitors under heavy use

Homeowners seeking enhanced security and convenience with smart access options.
Consider your existing smart home ecosystem to maximize compatibility and functionality.
Consider your WiFi strength near your door before buying to avoid connectivity issues. Pair the lock with a reliable smart home hub if you want more automation options. Avoid if you need a keypad that’s easily visible in low light. Also, check battery levels regularly to prevent lockouts, as heavy use can drain batteries faster than advertised.
