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 BCM.

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.
