Rudy RUN Lock Box
Score: 78/100Rankings
The Rudy RUN Key Lock Box is a wall-mountable outdoor combination lockbox designed for securely storing up to five keys. It features a resettable 4-digit combination and waterproof construction, making it a robust and affordable alternative to portable models. It is best suited for homeowners and realtors who prefer a fixed, weatherproof installation over portable options.
The Master Lock 5422E is a portable, push-button key lock box designed for quick, tool-free installation on door knobs. While it offers excellent usability with its touch interface and weather protection, it suffers from a critical security vulnerability where the lock can be decoded. It is best suited for low-risk, temporary access scenarios where convenience outweighs high-security needs.
