Pop-A-Lock is America's Most Trusted Locksmith Franchise. Pop-A-Lock was born in 1991 when local law enforcement agents in Lafayette, Louisiana recognized the need for a car locksmith in their community. Since then, Pop-A-Lock has grown to become the largest professional locksmithing franchise in the country. Our original Lafayette location is now the national training facility and corporate headquarters for Pop-A-Lock. While our main focus is on emergency automotive locksmith services, we also offer a full range of services for your home and business security. In addition, we are proud to have created the Emergency Door Unlocking (EDU) Program - a free community service dedicated to saving children who are inadvertently locked in vehicles.
