10 Best Waterproof Door Lock 2025 in the United States

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 iulock Smart Door Knob is a solid choice for anyone looking for a convenient, secure, and weather-resistant door lock, especially for interior and exterior residential use. It features a keypad that can store up to 50 unique codes, which is great for families or rental properties where multiple users need access. The lock supports keyless entry but also comes with traditional keys, offering flexibility. The metal construction with a matte finish and rubber grip makes the knob both sturdy and comfortable to use, while the IP65 waterproof rating means it can withstand rain, dust, and extreme temperatures from -22°F to 176°F. This makes it suitable for front doors, backdoors, bedrooms, and even commercial spaces.

Installation is fairly straightforward, requiring only a screwdriver, and it fits a wide range of door thicknesses. The keypad is backlit and easy to use in the dark, with added features like silent mode and a passage mode for times when you want the door unlocked. Power comes from four AAA batteries that can last up to 18 months, plus a USB backup option in case the batteries die. However, it does require periodic battery replacement, and while the lock is sturdy, the security level is best suited for typical home or office needs rather than high-security environments.

The included 4-pack with same-key cylinders is convenient if you want uniform keys for multiple doors. This lock balances smart features, durability, and ease of use, making it a practical option for anyone needing a waterproof, keyless door lock without complicated installation or setup.

It stands out with its advanced biometric technology, allowing seamless fingerprint recognition that adapts to the users over time.

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.
