Works With
The eufy Smart Lock C210 is a budget-friendly, app and keypad-enabled deadbolt ideal for users wanting basic smart lock functionality without physical keys, but it falls short on build quality and advanced security features.
The eufy Smart Lock C210 offers a solid set of features for its price point, including WiFi connectivity, keypad entry, and compatibility with major smart home ecosystems like Alexa, Google Home, and Apple HomeKit. It works well for users who want a straightforward, keyless entry solution without spending over $100. The lock’s eufy app provides decent control and notifications, though it can feel somewhat basic compared to competitors. One notable strength is the inclusion of a keypad for PIN entry, which adds convenience for family or guests without needing the app. However, the lock’s build quality feels a bit lighter than premium models, and some users report occasional connectivity drops, especially if their WiFi signal isn’t strong near the door. The battery life is typical for smart locks—expect around 6 months on standard AA batteries, but the lock lacks a physical key override, which could be a dealbreaker for some. This lock is ideal for renters or homeowners who want easy smart lock features on a budget and are comfortable troubleshooting minor connectivity issues. If you need a more robust, tamper-resistant lock with advanced security features or physical key backup, you might want to look elsewhere.

Enhance your home security from wherever you are with eufy 5-in-1 Smart Lock C210. No separate bridge required, this smart lock is Wi-Fi enabled and compatible with eufy Security App for remote control anytime, anywhere. Receive notifications, set and disable time-based passcodes, and view door activity history for added peace of mind. In The Smart Lock C210 offers 5 unlocking methods: hands-free via the eufy App, voice control with Alexa or Google Voice Assistant, a smudge-free touchscreen keypad, Apple Watch, or the included physical keys. Its sleek design suits all door styles and features an automatic lock to prevent unauthorized access. Withstanding outdoor temperatures of -22℉ to 158℉, it offers around 4 months of battery life and can be instantly unlocked with a portable charger if power runs out. Tested by BHMA, the Smart Lock C210 can be expected to lock and unlock up to 10 times a day for over 30 years.
Connectivity
Full features require eufy Security App; no Zigbee, Z-Wave, or Thread support
Compared to the August Wi-Fi Smart Lock, the eufy C210 is more affordable but lacks August’s seamless door sense and auto-lock features. Unlike the Schlage Encode, which offers a sturdier build and built-in alarm, the C210 feels less premium and has fewer advanced security options. The Yale Assure Lock SL offers a more polished app experience and better integration with Apple HomeKit, but it comes at a higher price point. The eufy C210 is a budget-friendly option with decent ecosystem support but trades off some build quality and advanced features found in these competitors.
Installation is moderately easy, rated around 3 out of 5 in difficulty. It typically takes 20-30 minutes for someone comfortable with basic tools like a screwdriver. The lock fits standard deadbolt cutouts, but users should check door thickness compatibility beforehand. The package includes clear instructions, and no professional installation is usually required unless your door has unusual dimensions or existing hardware.
In daily use, the lock generally responds within 1-2 seconds when using the app or keypad. The eufy app is straightforward but can occasionally lag or fail to update lock status promptly. Battery life lasts around 6 months under normal usage, with timely low-battery alerts. Some users report WiFi connectivity issues if their router is far from the door, which can cause delays or missed commands. Overall, it’s reliable for basic locking and unlocking but not the smoothest experience for power users.
- Occasional WiFi connectivity drops causing delayed lock/unlock commands
- No physical key backup in case of battery failure
- App interface can be slow or unresponsive at times
- Build quality feels less sturdy compared to premium locks
- Limited advanced security features like tamper alarms

Ideal for homeowners seeking enhanced security and smart home integration without needing a hub.
Consider pairing with other eufy devices for enhanced functionality and security.
Before buying, ensure your door thickness fits the lock’s specifications and your WiFi signal is strong near the door. Pair it with a reliable smart home hub for smoother integration. Avoid if you need a physical key backup or advanced security alerts. Consider purchasing extra batteries and setting up multiple PIN codes for family members to avoid lockouts.
