| 摘要 |
The invention relates to a method for controlling a code in a security system and to a security system comprising at least one permissible code and electronic control means consisting of a transmitter/receiver for communication with at least one permissible code. The control means produce an authorization for access to a secure object when authentication data is received from the at least one permissible code and store determinate identification data for the at least one permissible code. The method includes access to determinate identification data for the at least one permissible code in a mode of said system. The inventive method is characterized in that enabling data, corresponding to the determinate identification data of the at least one permissible code, is stored and the user follows a predetermined procedure in order to enter into a code validation mode of said system, maintain the enabling data for permissible codes in said validation mode inside the range of the transmitter/receiver and to delete the enabling data for permissible codes located outside the range of the transmitter/receiver, whereby codes without enabling data for the system are deactivated. |
