Abstract

L'invention concerne un verrou de porte électronique programmable pour accepter de nouveaux dispositifs de clef de données valables, en utilisant un dispositif de clef de données spécifique choisi dans un ensemble de dispositifs de clef de données spécifiques, aux fins de programmation et de commande. Le verrou comporte un régisseur de mode d'apprentissage réagissant à un dispositif de clef de données d'apprentissage, afin d'entrer dans un nouveau mode d'apprentissage de clef de données d'accès valable. Un enregistreur de code d'accès valable réagit à un premier code antérieurement inconnu, propre à un premier nouveau dispositif de clef de données, durant le mode d'apprentissage, afin d'enregistrer le premier code inconnu en tant que code d'accès valable pour le fonctionnement du verrou. Un enregistreur de code d'annulation réagit à un second code antérieurement inconnu propre à un second nouveau dispositif de clef de données, durant le mode d'apprentissage, afin d'enregistrer le second code inconnu en tant que code d'annulation associé à un code d'accès valable du premier nouveau dispositif de clef de données. A l'utilisation, le verrou est activé aux fins d'ouverture en réponse au code d'accès valable du premier nouveau dispositif de clef de données, et il est activé aux fins d'annulation du code d'accès valable enregistré en réponse au code d'annulation du second dispositif de clef de données. Le verrou peut fonctionner avec l'un quelconque des dispositifs de clef sans préprogrammation spécifique. La programmation et la commande sont facilitées par l'utilisation de dispositifs de clef de données spécifiques à marquage hiérarchique distinct, pour des opérations spécifiques de programmation et de commande distinctes.
