Suburban Door Check & Lock Services was started in 1963 by Larry Barrett Sr. with the goal of providing sales and service on all types of locks and door closers. Larry began his career working for a large locksmith in the Chicago area. When Suburban Lock first opened, the business was small with one service vehicle and Larry ran service calls. As the business grew, Larry added employees and service vehicles. In 1986 an addition was built on to the existing shop, expanding the square footage to about four times the size. Today, the company has 28 employees and 16 service vehicles and is still a family owned and operated company. At Suburban Lock, our work is 100% guaranteed, making us a company you can depend on.
