Abstract: A method for pairing an identification (ID) transmitter and a base of an authentication device includes a programmer initializing the base by transferring an assigned base identification and a code to the base via a first link. The first link differs from a control link used by the ID transmitter to communicate a code to the base. The base then initializes the ID transmitter by transferring to the ID transmitter via a second link an assigned ID transmitter identification which corresponds to the base identification of the ID transmitter and the code. The second link differs from the other links. The ID transmitter is initialized in order to receive authentication from the base to cause the base to trigger an object assigned to the base when the ID transmitter has an ID transmitter identification corresponding to the base identification and communicates the code to the base via the control link.
