Mechanical and electronic locks – expertise from the beginning

For over 160 years DLP has been manufacturing high-precision locks and fittings. In the 1930s, the aspiring company increasingly focused on the automotive industry and supported for example the VW Beetle with the development of new concepts for door handles and window locks.

Today, as a family-owned company in its fifth generation, managed by Dipl. Wi. (FH) Michael La Porte, we are firmly established on the market as the technology leader in the field of locking systems for off-highway vehicles.


Focus on the essentials. Dietrich La Porte establishes a German trading business in Vörde, which soon expands its activities to the production of locks, fittings and tools for the furniture and construction industry. The foundation for DLP has been laid.


Came to stay. The company relocates its headquarters to Wuppertal-Barmen — and remains loyal to the location for more than 100 years. The furniture locks, keys and fittings from our own production are already exported beyond the borders, to Russia for example.


DLP starts. As a supplier to the rapidly growing automotive industry, DLP produces latch locks, revolving door locks, square handle door handles, window displays, closing wedges and various custom-made products. Customers include major companies.


Companies on growth course. In the course of mass production in the furniture sector, the demand for low-cost locking systems is high. DLP develops low-cost furniture locks with keys, fittings made of die-cast zinc and other accessories for the furniture industry in large numbers.


Well-known customers rely on DLP. In-house stamping shop, foundry, plastic injection molding, assembly department, mold and tool making — through the high level of vertical integration, DLP can respond individually to customers. Including Miele, Samsonite, Grohe, Hansa, Staff-Zumtobel.


Focus on off-highway. DLP develops and produces locking systems for commercial vehicle cabins and becomes an innovative solution provider for the international commercial vehicle industry and cabin manufacturers. As one of the pioneers in the field of one-key systems, DLP is equipping the automotive supply industry for the first time with cylinders for ignition starter locks.



DLP invests in the future. The performance potential of the locally integrated development department gives DLP a clear lead in the market. In addition to building a linear production process, investments are made in new manufacturing technologies, such as the plastic injection in the gas internal pressure process.

More flexibility, more production capacity. After more than 100 years at the Wartburg and Hünefeldstrasse locations, DLP is relocating to new modern Wuppertal premises in the Niedergebreck industrial area, thereby combining three existing plants into a sophisticated overall concept.

DLP is breaking new ground. The relocation makes it possible: Through the use of modern production technologies and the expansion of the product range with electronic components and a large number of further innovative products, DLP can expand and strengthen its position on the market.



Welcome to the USA. With the founding of DLP USA, “Made in USA” is produced so that DLP can react to trends within the American commercial vehicle market with specific solutions. Also beneficial: support in sales and adherence to tight timelines within development processes.



Foundation of D. La Porte Asia Ltd. The new Chinese subsidiary is the cornerstone of a network of trusting partnerships in various Asian countries, which will further advance the growth of DLP in the global marketplace.


Open to new things. Radio remote control systems are conquering the commercial vehicle industry, not only increasing driver comfort, but also ensuring safety for the cab and workplace. DLP sells the first radio remote control systems to a well-known construction machinery manufacturer.

Electronics prevails. More and more customers are interested in the radio remote control and its features. DLP supplies them with innovative systems in the modern modular design, which is designed for the toughest requirements of the off-highway market.
