Product Information
Full details
The Master Lock 5422D Portable Lock Box is an ideal solution for homeowners, real estate agents, and property managers who need a secure, temporary, or permanent way to store spare keys and access cards. Its key benefit is the user-friendly, alpha/numeric push-button keypad that allows for a custom combination, providing both security and ease of access. While highly durable, users should note that as a portable device, it is best suited for scenarios where it can be shackle-mounted securely to a door handle or railing rather than permanent wall installation.

Setup, Compatibility & Care
To set up your combination, open the box, locate the internal mechanism, and follow the instructions to set your chosen sequence of letters or numbers. Ensure the shackle is fully clicked into the locked position before leaving the unit unattended. Compatibility is broad, as the shackle fits most standard door handles and fixtures. To care for your lock box, periodically wipe the exterior with a dry cloth and ensure the weather cover is firmly snapped into place. Do not use heavy lubricants on the buttons, as these can attract dirt.
