Estudio comparativo en diferentes equipos de programación de transponders para sistemas inmovilizadores de vehículos tipo M1 en el Distrito Metropolitano de Quito.

Abstract

This research focuses on a comparative study of four transponder programming systems applied to five M1 vehicle models. The aim is to establish a robust database to drive development and efficiency in the automotive sector and to generate an instructional manual for technical personnel for educational purposes. The immobilizer modules were extracted from each vehicle, and then the above-mentioned programming equipment was used. These activities were carried out using two programming methods: the first using the File (write) method and the second using the OBD II protocol to collect the required information. With the gathered information, defined criteria were developed to evaluate each programming kit. Factors considered included compatibility with different vehicle models, time efficiency, cost associated with the equipment, and ease of use. Based on the information gathered, it was determined that the equipment has limitations in terms of its capacity to simultaneously read memories and generate keys. None of the equipment has both functions integrated, so it is recommended to complement each other's equipment to solve this limitation. Finally, the last step consisted of elaborating a practical guide based on the field tests carried out together with the results obtained. The main purpose of this guide is to simplify and optimize transponder programming processes to facilitate learning for technical staff involved in the implementation of vehicle security. One of the future projects to be developed is research on advanced techniques for the twinning of immobilizer modules. This research broadens the scope of the current project by providing complementary information on immobilization systems, thus enriching the educational value of the manual and the associated technical training.
