Kidde KeySafe Original Slimline Push Button Combination Key Lock Box

In this review the Kidde KeySafe Original Slimline is presented as a straightforward solution for anyone who needs reliable, permanent key storage for one or two keys. The bottom line: it is best for families, renters and small service providers who want simple, weather-resistant access without electronics. Its main advantage is a mechanical push-button combination that is easy to set and use, giving controlled keyless entry for children, cleaners or tradespeople while avoiding the fragility and battery dependence of modern smart locks.

Key Features

• Permanent wall-mount storage: Mounting hardware is included so the unit can be secured to a wall or doorframe for long-term, convenient access.
• Two-key capacity: The slim interior holds up to two standard keys, making it suitable for a household or small business needs without wasted space.
• Push-button combination: The mechanical code uses push buttons and offers over 1,000 unique combos for a customizable, keyless entry method.
• Weather-resistant metal construction: Built to resist rust and outdoor exposure so it can be installed outside for after-school access and service visits.
• Simple setup: Comes with mounting hardware and a compact design that blends in with many surfaces for quick installation.
• Frustration-free packaging: Ships in easy-open packaging to reduce waste and speed setup.

Who It's For

The KeySafe Original Slimline is ideal for parents who need safe after-school access for children, landlords who want a simple way to provide entry for tenants or maintenance, and homeowners who frequently misplace their keys. The durable metal case and mechanical lock make it a good fit where reliability and low maintenance are priorities.

It is less suitable for users who want to share access remotely or need to track entries - there is no electronic logging or remote control. If you need higher capacity for multiple keys or advanced access features, a larger or electronic solution should be considered.
