Circuit/System Verification

WARNING: This page is about a different car, the 2015 Chevrolet Trax and 2015 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.
  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.
    • If the K9 Body Control Module does not exit the learn coded key state after the programming attempt 

      Replace the K9 Body Control Module

    • If the K9 Body Control Module exits the learn coded key state after the programming attempt 
  4. All OK.
