Erase All Key Codes and Program Two Keys

NOTE
^ This procedure is used when a customer needs keys programmed into the system and does not have two programmed ignition keys available. This procedure is also useful when programmed ignition key(s) have been lost and/or the ignition switch assembly has been replaced, and it is necessary to erase key(s) from the passive anti-theft system (PATS) memory.
^ This procedure will erase all programmed ignition keys from the vehicle memory and the vehicle will not start until two keys have been programmed.
^ Two PATS encoded keys with the correct mechanical cut must be available to carry out this procedure. One or both of them may be the customer's original keys.
^ If additional keys are to be programmed. If the remaining keys are with the customer and are not available with the vehicle, then instruct the customer to refer to the Owner's Guide for instructions on programming the remaining keys.
