The best commercial locksmith serving Orange County and Southern California.
For more than 40 years, the Yost family has designed, installed and serviced commercial security across Orange County. The relationships tend to outlast the hardware.
Founded in 1984. Still family-run.
Action 1st Loss Prevention, Inc. has protected Orange County businesses since 1984. What started as a family commitment to doing security work the right way became a full-stack commercial integrator: locksmith, access control, video surveillance and door hardware, all under one roof.
Russell Yost and the Yost family still run the business the way it began: pick up the phone, walk the building, recommend what the customer actually needs, and stand behind the work. Most of our new clients come from referrals by existing ones, which, after four decades, is the only scorecard that matters.
Being both a licensed commercial locksmith and an access-control integrator is rare. When a key and a credential are both part of the problem, our customers get one company that solves the whole opening, instead of hiring a locksmith and an access-control vendor separately. Your safety and security come first — we're known for dependability, responsiveness, and professionalism.
