The auto lock door function has evolved from a simple convenience feature to an integral component of vehicle security systems, providing automatic door locking based on vehicle speed, transmission engagement, or remote actuation through keyless entry systems. Sakes Auto Parts, founded in April 2016 by several powerful regional dealer representatives in Shanghai’s Anting Town, was established to address the automotive aftermarket’s demand for transformation and upgrading, and our close-interest community structure enables us to approach auto lock door system engineering with a comprehensive understanding of the integration between electronic controls, mechanical actuators, and vehicle body electronics. Through our unified management across different administrative areas and strategic capital pooling, we ensure that the auto lock door components we supply under the SAKES brand are manufactured with precision electrical characteristics, reliable mechanical linkages, and durable housings that withstand the repeated actuation cycles and environmental exposure encountered throughout the vehicle’s service life. Our deep expertise in Volkswagen and Audi platforms has given us unique insights into the specific auto lock door requirements of these vehicles, where central locking systems incorporate sophisticated control strategies, crash-activated unlocking, and integration with passive entry systems that demand components capable of reliable performance across diverse operating conditions. By integrating research, development, production, sales, and service under one unified structure, we deliver auto lock door solutions that help professional technicians restore proper automatic locking function, reduce the likelihood of system malfunctions that compromise vehicle security or convenience, and provide end consumers with the confidence that their vehicle’s entry and security systems are equipped with components engineered for reliability, smooth operation, and long service life.
