Анотація: (English) The article investigates the comprehensive transformation of the operational environment of the independent US automotive aftermarket. The subject matter is examined in the context of the transition from traditional highly specialized transponders to programmable ecosystems of universal smart keys and multi-protocol superchips. Special attention is given to microeconomic shifts, problems of cryptographic fragmentation and cognitive adaptation of human capital to the new digital reality. The work is directed at identifying pathways for the optimization of logistical resources, the minimization of technological risks and the institutional legalization of processes through federal cybersecurity standards. The research architecture is based on a pragmatic approach applying a convergent mixed-methods design. The quantitative stage includes financial modeling and operational time studies based on 120 American service centers. The qualitative stage relies on unstructured expert consultations with 45 certified vehicle security professionals and thematic synthesis of their cognitive load. The use of multi-protocol superchips creates a “sandbox environment” that fosters a heuristic approach to programming. The extensive model of physical inventory accumulation is increasingly supplemented or superseded by digital flexibility, which reduces the warehouse nomenclature by approximately 84.3%. The key achievement of innovation management is the improvement of cognitive ergonomics: the decoupling of cryptographic code from the hardware carrier and the possibility of multiple rewriting of superchips institutionalize the “right to error”. This substantially reduces cognitive overload and the professional stress level of engineers by approximately 62%. The successful assimilation of technologies is possible only under strict legal compliance (NASTF, SDRM), which transfers specialists into the status of authorized data analysts, challenging traditional dealer service models.
