Frequently Asked Questions (FAQ) about eufy Smart Locks
Q1: Are eufy smart locks secure?
A1: Yes, eufy smart locks are designed with robust security features. Many models are BHMA Certified, meaning they’ve undergone rigorous testing for durability and security. They often include wrong-try protection, alarms for unusual attempts, and secure local storage for biometric data (like fingerprints or palm veins).
Q2: How do eufy smart locks get power, and how long do their batteries last?
A2: eufy smart locks typically use either rechargeable lithium batteries or standard AA batteries. Battery life varies significantly by model, ranging from 5-8 months for AA battery models (like C220, C30) up to an impressive 12 months or even a full year for high-capacity rechargeable models (like S230, E330, C33). Some advanced models like the FamiLock E34 even feature dual power supply systems for uninterrupted operation.
Q3: Are eufy smart locks easy to install myself?
A3: Absolutely! One of eufy’s strong points is DIY-friendly installation. Most models can be installed in about 15 minutes with just a screwdriver, fitting standard US and Canadian deadbolt spacings. Crucially, many eufy smart locks come with built-in Wi-Fi, meaning you don’t need to drill holes for an extra bridge or hub.

Q7: Can I integrate my eufy smart lock with my existing eufy doorbell or camera?
