Circuit/System Verification

  1. Verify all available keys are correct for the vehicle. This can be accomplished by comparing the part number that is laser etched on the key to the part number listed in the parts catalog.
    • If a key is not correct 

      Replace the key

    • If all keys are correct 
  2. Perform the Replacing Keys procedure. Refer to Key with Integrated Transmitter Programming .
  3. Verify the K9 Body Control Module learns the vehicle key and exits the learn coded key state. The scan tool Master Keys Learned parameter should increment to 1.

      Replace the K9 Body Control Module

    • If the K9 Body Control Module exits the learn coded key state after the programming attempt
