10 Best Waterproof Door Lock 2025 in the United States

The eufy FamiLock E34 is a smart, waterproof door lock designed to offer secure and convenient keyless entry. It meets the IP65 waterproof rating, meaning it can handle rain and dust well, making it suitable for outdoor front doors. The lock is made with durable materials, suitable for frequent use and exposure to elements. Its standout feature is the palm vein recognition, which offers a very high level of security by scanning the unique pattern of your palm veins, unlocking quickly and with near-perfect accuracy. This biometric system keeps your privacy safe by storing data locally on the lock, not in the cloud.

The locking mechanism is a Wi-Fi keypad deadbolt rated ANSI/BHMA Grade 1, indicating strong security and reliability. You can control the lock remotely via built-in Wi-Fi without needing an extra hub, and it integrates smoothly with popular smart home systems like Apple Home, Google Home, and Alexa.

Installation is DIY-friendly and designed to fit standard doors in the US and Canada without drilling, which should make setup straightforward for most users. The lock runs on a large rechargeable lithium battery lasting about 8 months, with a smaller backup battery inside to keep it working during power issues—this dual power system adds reliability. Its weight of about 3.7 pounds is heavier than some traditional locks and might require a sturdy door. While there are no monthly fees, the smart features depend on your Wi-Fi and smart home setup, which could be a consideration if your internet is unstable. This lock suits users seeking advanced security with biometric access, reliable outdoor use, and modern smart home integration in an easy-to-install design, though it may be more advanced than necessary for those preferring a simple mechanical lock.

The eufy Security Smart Lock C220 is a stylish deadbolt with a matching handleset, designed to give your front door a clean, cohesive look. It’s built with an IP53 waterproof rating, making it resistant to light rain and dust, suitable for most covered outdoor entrances but not meant for heavy water exposure. The lock features multiple ways to unlock your door: fingerprint recognition that learns over time for quick access, an app with built-in Wi-Fi for remote control, keypad, physical key, and voice commands through Alexa or Google Assistant. This flexibility is great for families or anyone wanting convenient entry options.

Installation is user-friendly, requiring about 15 minutes and no drilling, fitting most standard doors in the US and Canada. Security-wise, this is a BHMA-certified deadbolt, giving you reliable protection. It runs on 8 AA alkaline batteries, included, and can last up to 8 months depending on use, which means fewer battery changes but keep an eye on notifications for low battery. One thing to note is the IP53 rating means it’s not fully waterproof, so if your door faces harsh weather without cover, you might want to consider a lock with a higher waterproof rating.

This smart lock is well suited for homeowners looking for modern features, easy installation, and solid security with decent weather resistance for typical front door use.

The eufy Smart Lock C33 is a keyless fingerprint door lock designed for home, office, or garage use. It stands out with its advanced biometric technology, allowing seamless fingerprint recognition that adapts to the users over time. This feature ensures quick and easy access for all family members, including children and seniors. The lock includes an integrated Wi-Fi connection, which allows for remote control via an app, providing real-time notifications and detailed event history, enhancing the convenience of managing access from anywhere.

The auto-lock feature adds an extra layer of security by ensuring the door locks itself after a set period. The IP53 waterproof rating means it can withstand light rain and dust, but it might not be suitable for areas with heavy rainfall or direct water exposure. Made from durable materials, it is designed to handle various environmental conditions. Installation is straightforward and can be completed in about 15 minutes without the need for drilling, making it compatible with both left- and right-hand doors.

The lock is powered by an alkaline battery which offers up to 12 months of use on a single charge, reducing the need for frequent replacements. One downside is that it might not be as robust in extremely wet conditions due to its IP53 rating. Another consideration is that since it relies on Wi-Fi, a stable internet connection is necessary for remote access features. However, backed by reliable customer support and an 18-month warranty, the eufy Smart Lock C33 provides a balance of security, convenience, and ease of use for most residential and office settings.
