Bach and two partners founded The Briggs & Stratton Company in Milwaukee in 1908, initially making automotive ignition switches and locks. The automotive division operated inside Briggs & Stratton for decades before being spun off as STRATTEC Security Corporation, a standalone public entity trading under the ticker STRT. Today the company designs, develops, and manufactures mechanical locks, electronically enhanced locks and keys, steering column and instrument panel ignition lock housings, latches, power sliding side door systems, power liftgate systems, power deck-lid systems, door handles and related access-control products. The firm has historically concentrated its production in North America, operating facilities in Milwaukee, Wisconsin, El Paso and Juarez, Mexico. Nearly all revenue comes from a concentrated group of Detroit automakers. In its own regulatory filings, STRATTEC disclosed that General Motors, Ford, and Stellantis together represented over 80% of net sales in recent years. The company functions as an automotive tier-one supplier, meaning it provides complete subassemblies directly to OEM assembly lines rather than selling components to other suppliers. Its product set splits between traditional mechanical locks and newer electronic access systems that support keyless entry, push-button start, and vehicle security authorization. The shift toward vehicle electrification and software-defined architectures is forcing the entire supply base to re-engineer access systems away from mechanical interrupt points, a transition STRATTEC has been navigating through partnerships and licensing agreements, including a long-standing technology collaboration with WITTE Automotive in Germany. Jennifer Slater, appointed president and CEO in early 2023 after serving as chief operating officer, leads a business that has historically operated with a lean leadership structure. The board added former BorgWarner executive Frank Krejci as a director in 2024 to expand strategic capacity. Vehicle production volumes, which STRATTEC does not control, drive performance. A prolonged UAW strike or a slowdown in the Detroit Three's assembly output directly compresses the company's top line, as demonstrated during the 2023 labor actions and the 2020 pandemic shutdowns. The honest structural differentiator is not the technology itself — competitors at the same tier produce near-identical products — but the dependence on a customer concentration that creates an effective joint destiny with the largest American automakers. When those OEMs transition architectures, STRATTEC must transition with them. The firm cannot diversify away from its customer base without rebuilding its commercial model entirely, so its governance and strategy are fundamentally bound to the product cycles and capital-investment decisions made in Detroit. ## Sectors - Mobility & Transportation - Industrial Tech ## People - Jennifer Slater — President and CEO ## Questions ### Who makes the key and lock systems for General Motors, Ford, and Stellantis vehicles? STRATTEC Security Corporation is a primary tier-one supplier of mechanical and electronic lock sets, ignition assemblies, and access-control hardware to the Detroit Three automakers. The company disclosed in its most recent annual filings that these three customers represent more than 80% of consolidated net sales. STRATTEC also provides components to other vehicle access system suppliers through licensing and joint venture arrangements. ### What is the relationship between STRATTEC Security and Briggs & Stratton? STRATTEC was originally the automotive division of Briggs & Stratton Corporation, which was founded in Milwaukee in 1908. The automotive lock and key business was spun off as a separate publicly traded company, retaining the SEC filings and operating history of the original entity. No ongoing ownership relationship exists — STRATTEC operates independently and trades under the ticker STRT. ### Is STRATTEC Security a manufacturing business or a technology licensing company? It is both. Approximately two-thirds of its revenue comes from manufacturing mechanical and electronic lock sets, ignition housings, power door and liftgate actuators, and related hardware at its plants in Wisconsin and Mexico. The remainder comes from licensing intellectual property and providing engineering services to WITTE Automotive, a German supplier, and other vehicle-access companies through long-standing joint venture agreements. ### What happens to STRATTEC if automakers shift fully to digital keys and phone-based access? STRATTEC's survival in a fully electronic access environment depends on its ability to design and supply the electronic modules and software integration components that replace mechanical lock cylinders. The company has been transitioning its engineering toward electronic steering column locks, passive-entry sensors, and secure gateway modules, though its current balance sheet still reflects heavy mechanical product concentration. Its WITTE partnership has historically been the vehicle for accessing European and digital-access technology. ## Related profiles - [Eagle Nuclear Energy Corp.](https://altss.com/profile/eagle-nuclear-energy-corp) - [ANVI Global Holdings](https://altss.com/profile/anvi-global-holdings-inc) --- Last updated: 2026-06-03T20:00:00.000Z Canonical page: https://altss.com/profile/strattec-security-corp Maintained by Altss — https://altss.com — methodology: https://altss.com/methodology
