1. A keyboard system comprising:
a housing;
a key structure disposed in the housing, the key structure including:
a key body including a transceiver circuit; and
a key cap configured to be non-destructively coupled to and decoupled from the key body, wherein the key cap includes and contains:
a transceiver circuit; and
a memory structure storing:
a key cap identification (ID) data; and
a key function data corresponding to a key function,
wherein the transceiver circuit is configured to poll the key cap memory structure via the transceiver circuit when the key cap is coupled to the key body and retrieve the key cap ID data and the key function data, and
wherein the keyboard system is configured to:
determine a location of the key cap on the keyboard based on the polling of the key cap; and
generate and transmit a control signal to a host computing device communicatively coupled to the keyboard system, the control signal corresponding to the key cap ID data and key function data.
