Key Programming - Erase All Key Codes and Program Two Keys

NOTE: Two PATS keys with the correct mechanical cut must be available to carry out this procedure.

NOTE: This procedure erases all MyKey® features on all of the keys that are programmed to the vehicle. All of the keys then operate as normal (admin) keys with no restrictions.

From the scan tool, enter TOOLBOX. Select BODY>SECURITY>PATS Functions and follow the IDS on-screen instructions to PATS security access.
From the scan tool menu, select "Ignition Key Code Erase" and follow the IDS on-screen instructions until the key erase procedure completes. The scan tool then instructs you to program 2 keys to complete the process.
Turn the key to OFF and disconnect the scan tool (the key does not need to be removed from the ignition switch at this time).
Turn the first PATS key to RUN for a minimum of 6 seconds.
Turn the first PATS key to OFF and remove the key from the ignition key cylinder.
