Spare Key Programming - Without Programmed Keys

NOTE:
- This procedure is 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 or/and the ignition switch assembly has been replaced, and it is desired to erase key(s) from 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 reprogrammed to the vehicle. If only one encoded key is supplied to the dealership, a second encoded ignition key must be mechanically cut for the vehicle and programmed. A customer must be notified that other encoded ignition keys in their possession will no longer start the vehicle unless these keys are reprogrammed to the vehicle.
- Two PATS encoded keys with the correct mechanical cut must be available to perform this procedure. One or both of them may be the customer's original keys.
- If additional keys are to be programmed, follow Spare Key Programming - With Programmed Keys. 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 Manual under the "Programming Spare Keys Procedure" for instructions on programming the remaining keys.
