10 Best Alexa Compatible Door Lock 2025 in the United States

The eufy Security Smart Lock C220 is a solid choice if you want a deadbolt lock that integrates well with Alexa and other smart home systems without needing extra bridges thanks to its built-in Wi-Fi. It offers convenient unlocking options, including fingerprint recognition, keypad, physical key, app control, Apple Watch, and voice commands through Alexa or Google Assistant. The fingerprint sensor is smart and improves with use, making it quick and reliable to unlock the door. Installation is straightforward and doesn't require drilling, fitting most standard US and Canadian deadbolts, which should make setup easy for most homeowners.

One of the strongest features is its long battery life; it runs on 8 AA batteries that can last approximately 8 months, reducing the hassle of frequent changes. The lock is also durable and weather-resistant with an IP53 rating, suitable for various climates, and includes security alerts for unusual activity. The app allows you to manage access codes, receive notifications, and check event history from anywhere, offering peace of mind and full control remotely.

On the downside, while it supports multiple unlocking methods, the lock’s reliance on alkaline batteries means you will need to keep spares on hand, and heavy use may shorten battery life. It’s also rated BHMA Grade 3, which is good but not the highest security grade available, so those needing top-tier protection might want to consider other options. Some users may find the rectangular design a bit bulky compared to sleeker models. This lock is ideal for homeowners looking for a user-friendly, Alexa-compatible smart lock with robust remote features and convenient fingerprint access. It balances ease of installation and good security features well, making it a practical upgrade for front doors in typical residential settings.

The eufy Security Video Smart Lock E330 offers a comprehensive 3-in-1 solution combining a smart lock, video doorbell, and fingerprint recognition, making it a strong contender for anyone seeking enhanced front door security. This lock type is a combination lock that supports five different unlocking methods: fingerprint, app control, voice assistant, keypad, and traditional keys, providing versatility and ease of use. Its compatibility with Alexa and Google Voice Assistant adds to its appeal for smart home enthusiasts.

The built-in 2K HD camera with night vision ensures clear visibility and security around the clock. Installation is straightforward, taking about 15 minutes without the need for drilling, and it's designed to fit most standard US and Canadian deadbolt spacings. The large rechargeable battery (10,000 mAh) is a major plus, eliminating the need for frequent battery replacements and ensuring all features are powered reliably. Remote access via the eufy Security app allows users to manage the lock and monitor visitors from anywhere, with push notifications providing real-time updates.

However, some users might find the requirement for cloud storage of thumbnail previews for notifications as a potential privacy concern. Additionally, while the aluminum build and sleek design are appealing, the size (8.7 x 7.08 x 3.13 inches) might be bulkier than some users prefer. This smart lock is particularly suited for those looking for a high-security, feature-rich, and easy-to-install solution for their front door.

The ULTRALOQ U-Bolt Pro WiFi Smart Lock is a highly versatile and secure option for those seeking an Alexa-compatible door lock. Its key strengths include an 8-in-1 keyless entry system with a variety of access methods such as fingerprint ID, keypad, and smartphone app control. The built-in WiFi eliminates the need for an additional hub, simplifying setup and use. The lock’s ANSI Grade 1 certification ensures top-tier security and durability, making it a reliable choice for homes, apartments, offices, and even Airbnb properties.

Additionally, it integrates seamlessly with smart home systems like Amazon Alexa, Google Home, and SmartThings, allowing for voice control and advanced home automation. The auto-lock and auto-unlock features, along with the included door sensor, enhance security and convenience by ensuring the door is always properly secured and providing alerts if the door is left open or unlocked. Installation is user-friendly, only requiring a screwdriver, and most users can complete it in about 10 minutes. The lock is powered by 4 AA batteries, which are included, and offers a decent battery life.

However, some users might find the requirement of a 2.4GHz WiFi network limiting, as it does not support the faster 5GHz networks. With a lifetime mechanical warranty and 18 months electronic warranty, it promises long-term support and peace of mind for users.
