NOTE: This procedure is used when a customer needs keys programmed into the system and does not have 2 programmed ignition keys available. This procedure is also useful when programmed ignition key(s) have been lost or a new ignition switch assembly has been installed, and it is desired to erase key(s) from the passive anti-theft system (PATS) memory.

NOTE: This procedure erases all programmed ignition keys from the vehicle memory and the vehicle will not start until 2 keys have been reprogrammed to the vehicle.

NOTE: 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 original keys.

NOTE: If additional keys are to be programmed, refer to KEY PROGRAMMING USING TWO PROGRAMMED KEYS in this article. If the remaining keys are not available with the vehicle, instruct the customer to refer to the Owner's Literature for instructions on programming the remaining keys.
