Master Lock Black Outdoor Key Lock Box 5422E - Secure Key Storage

Our review of the Master Lock Black Outdoor Key Lock Box 5422E finds it most useful for homeowners, landlords, and short-term rental hosts who need a simple way to share access without handing out physical keys. The biggest reason to buy is its combination of a push-button, resettable code and a durable metal body with a weather cover, which together provide reliable, weather-resistant key storage that can hold multiple keys and be programmed for temporary or long-term access.

Key Features

• Large capacity: Internal space fits up to five standard keys, letting families or small teams keep multiple spares in one secure spot.
• Push-button resettable code: The alpha/numeric combination can be set and changed without tools, making it easy to share access with tenants or guests.
• Weather protection: A protective weather cover helps prevent freezing and jamming of the combination buttons for outdoor placement.
• Durable construction: Metal body and vinyl-coated shackle resist wear and help prevent scratching on doors or hardware.
• Mounting flexibility: Can be wall mounted or hung on compatible door knobs, fitting most ball, biscuit, and tulip styles when dimensions match.

Who It's For

This lock box is ideal for homeowners who want a reliable way to hide a spare key outside, property managers or landlords who need to provide access to contractors and tenants, and short-term rental hosts who frequently change guest codes. It suits anyone who values a mechanical, battery-free option for shared access.

Those who should look elsewhere include users who need electronic audit logs, remote opening, or integration with smart home systems; this is a mechanical lock box without digital connectivity. Also measure your door's backset, cross bore and thickness first, as the shackle and mounting fit are specific and may not suit every installation.

Pros & Cons

• Easy to program and reset for temporary or permanent codes, making code changes straightforward.
• Solid metal body and vinyl-coated shackle deliver a feeling of durability and resistance to everyday wear.

Cons
