ABSTRACT:
A key for an electronic lock system is provided with circuitry capable of performing a plurality of lock-related functions. Stored in the key is characterization data that determines the key's particular functionality be electronically disabling certain ones of these functions, leaving just a subset of functions from which the operator may select. Keys having various capabilities can thus be electronically tailored from a single master design.
