Red Obsidian Security

· 401 E 8th St Suite 200 L, Sioux Falls, SD 57103, USA

When a commercial tenant gets locked out at the wrong hour or a business needs its access control rekeyed after staff turnover, the call goes to Red Obsidian Security. Downtown Sioux Falls. Professional. Not a side hustle.

Red Obsidian Security handles locksmith and security work for both residential and commercial clients — rekeying locks, installing hardware, assessing vulnerabilities, and building out access solutions that actually match how a building gets used. The commercial side gets particular attention here, which matters when you're dealing with multi-tenant properties or businesses that can't afford a casual approach to who holds a key.

What earns repeat calls in this city is specificity. Red Obsidian isn't selling the same package to a homeowner and a downtown office suite. They size the job, spec the solution, and execute it without the upsell fog. For Sioux Falls businesses that want a security provider who operates like a professional outfit — not a franchise running on volume — that's the practical difference.
