The automotive door lock is a sophisticated assembly that combines mechanical latching, electronic actuation, and safety interlocks to secure the vehicle while enabling convenient entry and exit through key, remote, or passive access methods. Sakes Auto Parts, established in April 2016 by a coalition of influential regional dealer representatives in the automotive hub of Anting Town, Jiading District, Shanghai, was founded to satisfy the demand for transformation and upgrading within the automotive aftermarket, and our close-interest community structure enables us to approach automotive door lock engineering with a comprehensive understanding of the integration requirements for modern vehicle security systems. Through our unified management across different administrative areas and strategic pooling of capital resources, we ensure that every automotive door lock we supply under the SAKES brand is manufactured using precision-engineered internal components, robust electric actuators, and durable housing materials that withstand the thermal cycling, moisture exposure, and mechanical stress encountered throughout the vehicle’s service life. Our deep expertise in Volkswagen and Audi platforms has given us unique insights into the specific automotive door lock requirements of these vehicles, where features such as central locking, child safety locks, deadbolt functionality, and crash-activated unlocking demand components that deliver consistent performance across all operating conditions. By integrating research, development, production, sales, and service under one unified structure, we deliver automotive door lock solutions that help professional technicians restore proper door latching and security function, reduce the risk of lock mechanism failures that compromise vehicle safety, and provide end consumers with the confidence that their vehicle’s entry and security systems are equipped with components engineered for durability, reliable operation, and long service life.
