Key Programming - Erase All Key Codes and Program Two Keys

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.

NOTE: This procedure erases all programmed ignition keys from the vehicle memory. The vehicle cannot start until a minimum of 2 keys are programmed into the vehicle.

NOTE: To enter PATS security access if no programmed IA keys are available, start a vehicle session using a tear tag or PCM part number. PATS security access can still be granted even with the ignition off.

Using a scan tool, enter the PATS Functions and follow the on-screen instructions to enter PATS security access.
NOTE: A maximum of 8 keys can be programmed into the vehicle.

From the scan tool menu, select the appropriate key programming procedure and follow the on-screen instructions to erase and program the IA keys.
