  1. Perform the 10-Minute Vehicle Key Relearn procedure. Refer to Replacing Keys (Canada, Europe, Middle East, and Asia) .
  2. While viewing the scan tool VTD States parameter, turn ON the ignition with each of the available vehicle keys. The parameter should read Normal Decision with all available keys.
