FAQ: Your Burning Questions About eufy Smart Locks Answered
Q1: What is a eufy retrofit smart lock, and how is it different?
A eufy retrofit smart lock, like the E110, is designed to be installed on the inside of your door, directly over your existing deadbolt. This means it doesn’t change the exterior look of your door, and you can still use your original physical keys from the outside. It’s perfect for renters or those who want a non-invasive smart upgrade, as it preserves the original key functionality and appearance.
Q2: How easy is it to install a eufy smart lock?
Most eufy smart locks, including both retrofit and full replacement models, are designed for DIY installation in about 10-15 minutes, with no drilling required for standard deadbolts. They typically come with clear instructions and all the necessary tools (besides a screwdriver), making the process very straightforward for most homeowners.
Q3: Do eufy smart locks work with existing keys?
This depends on the type. The eufy retrofit smart lock (like the E110) explicitly allows you to keep and use your original physical keys from the outside, as it only replaces the interior turn piece. Full replacement eufy smart locks, however, will come with their own set of physical keys that replace your original ones.

eufy smart locks are almost universally battery-powered. They typically use AA batteries, with battery life varying from 5 months up to 14 months, depending on the model and usage frequency.

Q5: Can I control my eufy smart lock remotely?
Yes, absolutely! Most eufy smart locks feature built-in Wi-Fi, allowing for direct remote control, access management, real-time notifications, and event history via the eufy Security app from anywhere in the world, without needing an additional hub or bridge. Some models, like the E31, also offer robust remote control via smart home hubs like Apple HomePod.
Q6: Are eufy smart locks secure?
Yes, security is a top priority for eufy. Their smart locks often feature AES128 encryption for local data storage, BHMA certification for durability, tamper alarms for unusual entry attempts, and wrong-try protection that temporarily locks the system after multiple incorrect attempts. Auto-lock features also ensure your door is always secured even if you forget.
Q7: Do eufy smart locks integrate with other smart home systems?
Many eufy smart locks offer excellent smart home integration. Most work with Amazon Alexa and Google Assistant for voice control. Models like the E31 provide broader compatibility with Apple HomeKit and SmartThings. Within the eufy ecosystem, you can often link your smart lock with eufy doorbells for combined routines and seamless keyless entry experiences.
