eufy Smart Lock C30, Keyless Entry Door Lock, Built-in WiFi

Product Overview

The eufy Smart Lock C30 is a modern keyless entry deadbolt designed to bring smart home convenience directly to your front door—without the complexity of additional hubs or bridges. With built-in Wi-Fi connectivity, it enables seamless remote access through the intuitive eufy Security app, giving you full control whether you’re at home or away. Whether you’re managing access for family, guests, or service providers, this smart lock offers peace of mind with features like auto-lock, activity tracking, and voice compatibility. Engineered for reliability and ease of use, the C30 supports DIY installation in about 15 minutes and integrates smoothly with other eufy smart devices to create a unified home security system.

Key Features

• Remote Control via Built-in Wi-Fi: The C30 connects directly to your home Wi-Fi network, eliminating the need for an external bridge. Using the free eufy Security app on your smartphone, you can remotely lock or unlock your door from anywhere, grant temporary digital keys, receive instant notifications when someone enters or exits, and review detailed activity logs. This real-time visibility ensures you’re always informed about who accesses your home and when.
• Keyless Entry Options: Say goodbye to fumbling for keys. The C30 supports multiple entry methods: a physical button press, voice commands through Alexa or Google Assistant, or traditional key backup. Unlike touchscreen locks that can suffer from smudges or false inputs, the C30’s physical button design resists wear and reduces user error, delivering consistent performance even in humid or dusty conditions.
• Auto-Lock Functionality: Never worry about forgetting to secure your door again. The auto-lock feature allows you to set a timer in the eufy Security app (ranging from 5 seconds to 30 minutes). Once triggered, the lock automatically engages after the selected interval—regardless of whether the door was left open or closed. This ensures your home remains protected without requiring manual effort.
• Quick and Simple Installation: Designed for compatibility with most standard deadbolts, the C30 installs in approximately 15 minutes using basic tools and no drilling. Its plug-and-play setup means you don’t need professional assistance or specialized knowledge. Just remove your existing deadbolt, replace it with the C30, connect to Wi-Fi, and sync with the app. Ideal for renters and homeowners alike, it preserves your door’s structural integrity while upgrading functionality.
• Smart Home Integration: Enhance your daily routine by pairing the C30 with compatible eufy devices—such as the eufy Doorbell series—to build a cohesive smart home ecosystem. For example, when motion is detected near your doorbell, the system can send a notification and log entry events alongside lock status changes. All actions are managed centrally through the eufy Security app, offering streamlined control over keyless entry and home automation.

Benefits & Use Cases

The eufy Smart Lock C30 excels in scenarios where convenience meets security. Busy parents benefit greatly from being able to grant trusted caregivers or babysitters digital access without sharing physical keys. It’s especially useful during drop-offs, late-night pickups, or when coordinating deliveries. Similarly, frequent travelers appreciate the ability to monitor and control their home while abroad, ensuring doors remain locked and entry logs are accessible in real time.

For tech-savvy individuals building a smart home, the C30 offers reliable integration with other eufy ecosystem products. When combined with a video doorbell, users gain a complete picture: see who’s at the door before unlocking, receive alerts upon arrival, and maintain a searchable history of all access events. This synergy enhances both safety and convenience.

Durability is another standout feature. With an operating range spanning extreme temperatures and an IPX3 waterproof rating, the C30 performs consistently in diverse climates—from cold winter mornings to humid summer evenings. The low-battery indicator provides advance warning, preventing unexpected lockouts due to depleted power. And because it uses standard AA batteries, replacements are widely available and easy to install.

Important Notes

• The package does not include four AA batteries—you’ll need to purchase them separately.
• Customer support is available 24/7 via telephone, email, and LiveChat, backed by an 18-month warranty for added confidence and peace of mind.
• This model does not include a built-in camera or video feed; security monitoring relies solely on access logs, remote notifications, and event history within the app.
• Ensure your home’s Wi-Fi signal reaches the lock location for optimal performance. Thick walls, metal studs, or long distances from the router may reduce connectivity strength.
• While compatible with most standard deadbolts, verify your current lock’s dimensions and backset (typically 2-3/8″ or 2-3/4″) before purchasing to ensure proper fit.
