Abstract
A key (10) includes a transceiver core (12) that couples to antenna electrodes that include all or part of a key shank (11) and an electrically conductive surface (16). The transceiver core (12) utilizes these electrodes (11 and 16) to capacitively transceive information with a reader (41). The reader (41) may, in turn, utilize all or part of a keyed lock cylinder (43) as an antenna electrode.
