10 Best Weather Resistant Locks 2026 in the United States

The Master Lock Gold Outdoor Combination Lock is robustly designed for outdoor use, making it suitable for securing gates, sheds, and storage units. Its heavy-duty construction, featuring a zinc body and reinforced bumper, offers durability and reliability. A key strength is its weather resistance, achieved through a shackle seal and covered dials, protecting it from harsh elements.

The resettable four-digit combination mechanism is user-friendly, eliminating the need for a combination change tool, and the one-directional dial is convenient for low light conditions. The octagonal boron-carbide shackle enhances security by being significantly tougher than hardened steel, which is beneficial against cutting and prying attempts.

The lock's dimensions and extended shackle provide versatility in application, fitting various locking needs. However, at nearly 2 pounds, it might be heavier than some users expect, possibly limiting portability. Additionally, the combination lock mechanism might be less secure compared to keyed locks in extremely high-security areas, although it suffices for general outdoor use. The limited lifetime warranty adds to its appeal, ensuring long-term reliability. This lock suits those seeking a sturdy, weather-resistant padlock with easy-to-use features for securing outdoor property.

The Abloy Protec2 PL 362 Shrouded Hardened Steel Padlock is designed for high-security needs, making it suitable for securing shipping containers, railway wagons, trucks, and heavy sliding doors. It features a body made of case-hardened steel and a shackle made from case-hardened boron steel, both with a bright chrome finish, ensuring durability and resistance to physical attacks. The shackle has raised shoulders to protect against cutting and prying tools. The shackle height is 25 mm, and its diameter is 15 mm, which provides robust security, though it may limit compatibility with certain fittings due to its size.

The lock utilizes the ABLOY PROTEC² system, known for its high security and controlled key duplication, making it factory-level secure. One key can be programmed to open multiple locks, offering convenience in managing access. However, the lack of specific information on weather seals suggests that while the materials are durable, additional protection against extreme weather conditions might be limited.

The padlock complies with stringent security standards like EN 12320 (grade 6) and SFS 5970, SFS 7020 (FA grade 4). On the downside, the padlock is relatively heavy, weighing 2.87 pounds, which might impact portability. Additionally, its size and robust security features make it less discreet, and it lacks modern features like electronic access or app control, catering more to traditional key-based security needs.

The Master Lock Black Covered Aluminum Padlock is designed for both indoor and outdoor use, making it versatile for securing items like gym lockers. Its body is made of aluminum with a black vinyl cover, which offers protection against scratches and corrosion. This feature is particularly useful for weather resistance, as it helps the lock withstand various environmental conditions. The hardened steel shackle adds a layer of cut resistance, enhancing security against physical attacks.

The four-pin cylinder and dual locking lever mechanism are designed to resist picking and prying, adding another layer of security. However, the lock's plastic material might not be as robust as other metal options available in the market. The size of the lock is relatively compact, with a 1-9/16 inch (40mm) wide body and a 1/4 inch (6mm) diameter shackle, suitable for most general security needs. The shackle's clearance of 7/8 inch (22mm) length and 13/16 inch (21mm) width should fit standard gym lockers and other similar applications.

Ease of use is enhanced by the included two keys, which feature matching color key heads for convenience. The lock offers a good balance of security features and ease of use, making it suitable for users looking for standard security in moderately exposed areas.
