Master Lock 5423EC

Expert Review Analysis

The Master Lock 5423D is a wall-mount push-button combination lock box designed for the secure, permanent storage of up to five keys or access cards. It features a durable metal body, a weather-resistant cover to prevent freezing or jamming, and a customizable alpha/numeric keypad with large buttons for low-light usability.

✓ Best for: Homeowners, landlords, real estate agents, or businesses needing permanent, secure key storage at fixed locations like exterior walls. Specific use cases include spare key access for house cleaners or service professionals, rental property management for up to five keys, and gated entry points requiring weatherproof, combination-based entry.✗ Not ideal for: Users requiring temporary or portable key storage solutions, as the fixed wall-mount design limits flexibility. It is also not ideal for environments requiring illuminated keypads or fireproof storage capabilities.

Pros

✓Push-button keypad allows for setting custom combinations up to 12 characters long
✓Large buttons are easy to press in low-light conditions or while wearing gloves
