You can clear all MyKeys within the same key cycle as you created the MyKey. If you switch your ignition off, however, you will need to use an admin key to clear your MyKeys.
Note:   When you clear your MyKeys, you remove all restrictions and return all MyKeys to their original admin key status at once.
To clear all MyKeys of all MyKey settings, use the information display and the left-hand-side steering wheel controls:
  1. Access the main menu and select Settings, then MyKey and finally Clear MyKeys.
  2. Press and hold OK.
  3. When you finish clearing all MyKeys, the Type 3 information display adds a confirmation screen, MyKey Cleared.
