How to Choose the Best Eufy Smart Lock
Eufy smart locks are known for their local storage and lack of recurring fees. The main differences come down to unlock methods, connectivity, and whether you want a built-in video doorbell. Most models use 4 AA batteries and offer a backup key.
What to check before buying
Unlock methods: Decide if you want a fingerprint sensor, keypad, or both. The S230 offers the fastest fingerprint recognition. Connectivity: Models with built-in Wi-Fi (S230, S330) do not need a separate hub. The S220 requires the Eufy HomeBase. Door compatibility: Check your door thickness and backset. Eufy locks fit standard US doors but may not suit all European or UK doors without an adapter.
Mistakes to avoid
Do not assume all Eufy locks work with Apple HomeKit. Only specific models like the S231 offer HomeKit support. Avoid buying a lock without a physical key backup if you worry about battery failure. Also, be aware that the video doorbell lock (S330) is larger and may not fit narrow door frames.
Eufy Security Smart Lock Touch & Wi-Fi (S230)
Best OverallPros
- Fast and accurate fingerprint sensor
- No hub required for remote access
- Easy DIY installation
Cons
- No HomeKit support
- Fingerprint pad can get smudged
The Eufy S230 is the most balanced smart lock in the lineup. It combines a responsive fingerprint reader with a backlit keypad and built-in Wi-Fi, so you can lock or unlock from anywhere without buying extra hardware. Owner reviews on Amazon consistently praise the quick setup and reliable auto-lock feature.
Battery life is rated at up to 12 months with normal use, though heavy Wi-Fi usage can reduce that. The lock fits standard US doors and includes a physical key override. It is not compatible with Apple HomeKit, but it works well with Alexa and Google Assistant.
Eufy Video Doorbell Dual Cam with Smart Lock (S330)
Best Video + Lock ComboPros
- Integrated doorbell and lock
- Package detection camera
- No subscription needed
Cons
- Bulky design
- Fingerprint sensor not included
The S330 is a unique all-in-one device that replaces both your doorbell and deadbolt. It features a front-facing camera for visitors and a downward-facing camera to monitor packages. Owner reviews highlight the convenience of seeing who is at the door and remotely unlocking it through the same app.
The lock uses a keypad for entry and supports auto-unlock via geofencing. Battery life is shorter than the S230 due to the cameras, typically lasting around 6 months. The unit is larger than standard locks, so measure your door frame before purchase.
Eufy Security Smart Lock (S220)
Best Budget with HubPros
- Lower price point
- HomeBase extends range
- Works with Eufy security cameras
Cons
- No fingerprint sensor
- Requires hub for remote access
The S220 is a solid entry-level smart lock that relies on a keypad for entry. It connects to the Eufy HomeBase, which acts as a Wi-Fi bridge and local storage hub for the Eufy ecosystem. This makes it a good choice if you already own Eufy cameras or plan to build a smart security system.
Owner reviews note that the keypad is responsive and backlit. The lock is easy to install and supports scheduling for temporary codes. The main drawback is the lack of a fingerprint sensor and the need for the HomeBase, which adds to the overall footprint.
Eufy Security Smart Lock (S231)
Best for Apple HomeKitPros
- Native Apple HomeKit support
- ANSI Grade 2 certified
- Sleek touchscreen design
Cons
- No fingerprint sensor
- Touchscreen can be slow in cold weather
The S231 is the only Eufy lock with native Apple HomeKit support, allowing you to control it via Siri and the Home app. It features a capacitive touchscreen keypad and a built-in Wi-Fi module for remote access without a hub. The lock meets ANSI Grade 2 standards for residential security.
Owner reviews mention that the touchscreen is elegant but can be less responsive in very cold temperatures. The lock does not have a fingerprint sensor, relying solely on the keypad and app. It is a strong choice for Apple users who want a secure, HomeKit-compatible deadbolt.
Eufy Security Smart Lock (S210)
Best Simple Keyless EntryPros
- Very affordable
- Simple installation
- No app or Wi-Fi needed
Cons
- No remote access
- No smart features or logging
The S210 is the most basic Eufy smart lock, designed purely for keypad entry. It has no Wi-Fi, Bluetooth, or app connectivity, making it a simple replacement for a traditional deadbolt. You set a code on the keypad and use the physical key as a backup.
Owner reviews appreciate the low price and straightforward operation. However, it lacks any smart features like remote locking or activity logs. It is best for a secondary door or for users who only want keyless convenience without smart home integration.
