About

Hardware that thinks. Doors that just open.

Mister Key (MKC) is an electronic door hardware specialist. We supply smart locks, mortise and multipoint locks, commercial exit devices, and Apple Home–ready hardware to homeowners, builders, and security professionals nationwide.

We started MKC because choosing the right lock shouldn't require a locksmith's license. Whether you're securing a single front door or speccing an entire building, we pair pro-grade products with people who actually know handing, backset, and function.

What we stand for

• Pro-grade only. ANSI/BHMA-rated, code-compliant hardware — the same gear the trade installs.
• Real expertise. Our team helps you spec the right finish, function, and door prep the first time.
• Smart, secure, simple. From Apple Home Key to commercial access control, we make modern entry effortless.
