Master Lock 5423EC Wall Mount Key Lock Box – Push Button, 5-Key Capacity

Reliable, low-hassle key storage for homes and properties

The Master Lock 5423EC wall-mount key lock box blends a robust metal enclosure with a weather-ready design to keep up to five keys safe and accessible. Its push-button, user-settable combination reduces the need to carry spare keys while maintaining control over who can access them, making daily routines smoother for households and small teams.

Durability and weather resistance meet practical convenience in a compact form. A solid metal body provides long-lasting use, while a protective weather cover helps shield the keypad from rain and cold. The molded bumper and vinyl-coated shackle are designed to minimize scuffs on walls and fixtures, so you can mount it in entryways, garages, or outdoor alcoves with confidence.
