Works With
The eufy FamiLock E35 is a solid biometric smart lock for those who want palm scan access and smart home compatibility but may frustrate users needing more entry options or flawless biometric recognition.
The eufy FamiLock E35 is a smart deadbolt that combines traditional thumb-turn convenience with biometric palm scan technology for keyless entry. It supports integration with Amazon Alexa, Google Home, and Apple HomeKit, making it versatile for smart home setups. The palm scan feature is a unique selling point, offering quick and secure access without needing a phone or key. Setup typically takes around 20-30 minutes, and the lock supports up to 100 palm prints, which is generous for families or small offices. However, the palm recognition can be inconsistent for some users, especially if hands are wet or dirty, which can be frustrating. The lock also relies on four AA batteries, which last roughly 6-8 months depending on usage, but there’s no built-in rechargeable option. Another limitation is the lack of a touchscreen keypad, which some competitors offer for backup PIN entry. This lock is ideal for users who want biometric convenience combined with solid ecosystem compatibility, especially those invested in Apple HomeKit. However, if you need a lock with multiple entry methods or more robust biometric accuracy, you might want to look elsewhere. Overall, it’s a solid mid-range smart lock with a unique biometric angle but not perfect for everyone.

Connectivity
Full feature set requires stable Wi-Fi connection; biometric features are local only and may not integrate with all platforms.
Compared to the August Wi-Fi Smart Lock, the eufy FamiLock E35 offers biometric palm scanning, which August lacks, but August provides easier door compatibility and a more refined app experience. The Schlage Encode Plus supports Apple HomeKit like the FamiLock but includes a touchscreen keypad and built-in Wi-Fi, which eufy lacks, requiring a separate hub for some functions. The FamiLock’s palm scan is a standout feature but can be less reliable than fingerprint scanners found in some other locks. If biometric entry is a priority, eufy’s lock is worth considering, but for overall smart lock functionality and app polish, August or Schlage might be better choices.
Installation difficulty is about 3 out of 5. It generally takes 20-30 minutes for someone moderately handy. The lock fits standard deadbolt cutouts, but aligning the palm scanner properly can be fiddly. Basic tools like a screwdriver are needed, and the instructions are clear but somewhat sparse on troubleshooting. Professional installation isn’t necessary unless you’re uncomfortable with door hardware or wiring the optional hub.
Users report mostly reliable daily operation, with response times under a second for palm scans when conditions are ideal. The app is functional but not as polished as August’s or Schlage’s apps, sometimes experiencing connectivity hiccups. Battery life is decent at 6-8 months, but low battery alerts can be delayed. Some users note occasional failures in palm recognition, especially in humid or dirty conditions, requiring backup entry methods.
- Palm scanner can fail to recognize prints if hands are wet or dirty
- No touchscreen keypad for backup PIN entry
- App occasionally loses connection to the lock
- Battery life alerts are sometimes delayed
- Setup instructions lack detail for troubleshooting palm scan alignment

Consider installation requirements and ensure Wi-Fi coverage at your door.
Buy the eufy FamiLock E35 if biometric access is a priority and you use Apple HomeKit or Alexa. Pair it with a compatible smart hub for best experience. Avoid if you need multiple backup entry options or live in a high-humidity area. Don’t skip testing the palm scan thoroughly during setup to ensure it works with your hands under typical conditions.
