  • an identification system is incorporated with an identification code or codes within both the fob transmitter and receiver.

  • RKE systems have evolved in the marketplace, greater emphasis has been placed on increased security, reliability and flexibility.
  • One area of focus has been on enabling the user in the field to reprogram the identification code ( s ) stored in memory. This RKE feature provides the user with an additional form of protection by allowing changes to the identification codes.
  • the memory for storing the identification code(s) has been located in the receiver within the vehicle.

Abstract

Cette invention a trait à un dispositif permettant de mettre en route à distance une fonction, lequel dispositif comporte un premier émetteur-récepteur (20) qui, en mode émission, envoie un code d'identification stocké en mémoire (25). Ce premier émetteur-récepteur a en mémoire, à l'origine, un premier code d'identification. En mode reprogrammation, cet émetteur-récepteur (20) reçoit un nouveau code d'identification qu'il stocke en mémoire (25). Ce dispositif comporte, de surcroît, un second émetteur-récepteur (45) qui, en mode réception, reçoit le code d'identification mémorisé émis, vérifie sa validité et met en route la fonction si le code d'identification transmis est recevable. En mode reprogrammation, ce second émetteur-récepteur (45) transmet le nouveau code d'identification et le stocke dans la mémoire (25) du premier émetteur-récepteur afin de reprogrammer celui-ci (20).
