A system and method for enhanced security by incorporating RFID processing circuitry within a key switch assembly. The RFID key switch assembly includes four subassemblies; the key/tumbler assembly, rotating and stationary switch contacts, RFID Processing Circuitry and an electrical connection interface. The RFID Processing Circuitry incorporated in the key switch assembly reads RF signals transmitted from an RFID tag embedded in a key inserted into the key switch.
