Method for credentialing mechanical keys and associated devices

摘要

A method is presented for credentialing - that is here lending EAC (Electronic Access Control) separate identity to - mechanical cylinder lock keys. The method primarily involves that both existing mechanical encoding, "cuts", of existing to locks pertaining keys as well as already in locks installed and existing lock cylinders pertaining to such keys can remain unchanged; that the key is provided with at least one appurtenant electronic code carrier, separate or on board the key, lending the key programmed individual and transmissible electronic signature(s) or characteristic(s), viz. credential(s); and that the lock cylinder is provided with a reader device, external to this and essentially unchanged cylinder, mentioned reader device having an electronic capacity for receiving, reading and reacting to the credential(s) of a key, as well as an electromechanical capacity to either block rotation of a cylinder or preventing rotation of a cylinder to result in actuation of a lock having a mentioned cylinder unless the cylinder and the reader have received a key having for actuation of the lock approved programmed credential(s); and also that lock actuation for a special credentialed key is possible even though the cylinder of that lock doesn't rotate.
