YES, California requires that all gun locks be approved by the California Department of Justice. The California DOJ requires that a gun meet certain standards as approved by the “National Technical Systems” out of Wichita, Kansas.
On Monday, March 23, 2020 JD2Security received notification that it passed all tests with the “National Technical Systems”. April 15th, 2020, the California Department of Justice notified us that we are compliant with their firearms safety devices (FSD). Pursuant to California code of regulation, title 11, section 4096, this FSD was added to the roster of FSD certified for sale. This firearm safety device is a California-approved FSD that meets the requirements of penal code section 23655 and regulations issued thereunder. If you decide to keep a firearm in your home you must consider the issue of how to store the firearm in a safe and secure manner. California recognizes the importance of safe storage by requiring that all firearms sold in California be accompanied by a DOJ-approved firearms safety device or proof that the purchaser owns a gun safe that meets regulatory standards established by the Department. The current list of DOJ-approved firearms safety devices and the gun safe standards can be viewed by
