Abstract (en)
[origin: EP0825316A2] The method is used for key information transmitted from a central point to a remote point for recording on a data carrier, to allow replacement of a lost access key. Object information is transmitted from the remote point to the central point for read-out of the stored key information, which is encoded before transmission using a code which is stored at the central point and at the key and which must be used for decoding the received key information before it can be recorded on the data carrier.
