About TeacherLock.
-
TeacherLock was created by engineer, Sal Emma and his wife, Amy Emma, a school vice principal, who witnessed the urgent need for safer, faster, and code-compliant classroom lockdown solutions after the Parkland tragedy. Their patented design solved the industry’s biggest safety challenges—empowering teachers to protect students instantly without violating fire, ADA, or egress codes.
-
Today, TeacherLock is trusted by schools, districts, churches, and safety professionals nationwide. Still family-owned by Matt and Natalia Dubois—parents committed to protecting children—we continue to grow installation support, partner networks, and training resources. Each TeacherLock system is built with care, reliability, and compliance to help schools enhance safety without disrupting daily learning.
-
Our vision is to ensure every classroom in America has access to a fast, compliant, and effective lockdown solution. We aim to lead the industry through innovation, education, and partnerships that elevate school safety. TeacherLock will continue developing smart, accessible products that support educators and empower communities to protect what matters most.
