King Locksmith was founded by two partners with complementary skills in mechanical locksmithing and electronic access systems. One partner mastered structural door work, gates, and metal fabrication. The other specialized in commercial door hardware, code-compliant access, and integrated electronic locking. This combination gives us complete control over every component of your access system. We do not subcontract. We diagnose, repair, and verify everything ourselves. That is why clients trust us for complex, high-security projects.
