The Wikkit Key is an artifact designed to open the Slo-Time Envelope surrounding Krikkit and isolating it from the manipulative supercomputer Hactar. Arthur, Trillian, Zaphod, Ford and Marvin (who saved Zaphod 3 times) save the universe from the threat.
The pieces of the Wikkit Key are:
- The Steel Pillar of Strength and Power (Marvin's Leg)
- The Gold Bail of Prosperity (The Infinite Improbability Drive)
- The Silver Bail of Peace (The Rory Award)
- The Perspex Pillar of Science and Reason (The Argabuthon Sceptre of Justice)
- The Wooden Pillar of Nature and Spirituality (The reconstituted ashes of a cricket stump; "The Ashes")
The whole therefore forms a wicket, in the typical manner for cricket (as a sport). The "Slo-Time Envelope" is presumably also a reference to the overall languid pace of a cricket match.
