Integrated Keyhead Transmitter (IKT) Key Programming Using Diagnostic Equipment
NOTE: This procedure is used when a customer needs more than one key programmed into the system and does not have 2 programmed ignition keys
available. This procedure is also useful when a programmed ignition key(s) is lost or the ignition lock cylinder is replaced, and it is desired to erase key
code(s) from the Passive Anti-Theft System (PATS) memory.
NOTE: This procedure erases all programmed ignition keys from the vehicle memory. The vehicle will not start until a minimum of 2 keys are
programmed into the Instrument Cluster (IC). This procedure also erases the Integrated Keyhead Transmitter (IKT) Transmitter Identification Codes
(TICs) from the Smart Junction Box (SJB), preventing the erased IKT from operating the Remote Keyless Entry (RKE) functions on the vehicle.
NOTE: Two PATS encoded (contains a transponder) IKT keys (or standard PATS 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. One or both of them may be an IKT or a standard PATS key.
NOTE: If additional keys are to be programmed, refer to Key Programming Using Two Programmed Keys See: Accessories and Optional
Equipment/Antitheft and Alarm Systems/Testing and Inspection/Programming and Relearning/Key Programming Using Two Programmed Keys. If the
remaining keys are with the customer and are not available with the vehicle, instruct the customer to refer to the Owner's Literature for instructions on
programming the remaining keys. In this case, the IC PID SPAREKEY must be enabled.
NOTE: This procedure is not necessary if only the PATS transceiver was replaced. Replacement of the transceiver does not erase the PATS key codes
in the IC.
1. Turn the key from the OFF position to the ON position.
2. From the scan tool, enter TOOLBOX. Select BODY - SECURITY - PATS Functions and follow the Integrated Diagnostic System (IDS)
on-screen instructions to ENTER SECURITY ACCESS. For additional information, refer to Anti-Theft Security Access See: Accessories and
Optional Equipment/Antitheft and Alarm Systems/Testing and Inspection/Component Tests and General Diagnostics.
3. From the scan tool menu select: "Ignition Key Code Erase". Follow all IDS screen instructions until the key erase procedure completes. The scan
tool will also instruct to program 2 keys in order to complete the process.
4. Turn the key to the OFF position and disconnect the scan tool (the key does not need to be removed at this time).
5. NOTE: The RKE data transfer takes place between the key and the IC first. After both keys are programmed into the IC, then the RKE data
transfers from the IC to the SJB. Until the final data transfer takes place into the SJB, the RKE functions will not operate.
NOTE: IKT keys require a 6-second programming time frame for the RKE data transfer to take place, while standard PATS keys only require a
minimum of 3 seconds.
Turn the first PATS key in the ignition lock cylinder to the ON position for a minimum of 6 seconds (this additional 3 second time frame allows
for the RKE data transfer to take place).
6. Turn the first PATS key to the OFF position and remove the key from the ignition lock cylinder.
7. Insert the second PATS key into the ignition lock cylinder and turn the key to the ON position for a minimum of 6 seconds (this additional 3
second time frame allows for the RKE data transfer to take place).
8. Turn the second PATS key to the OFF position and remove the key from the ignition lock cylinder.
9. The vehicle should now start with both ignition keys and the RKE transmitter portion of the IKTs should function.
10. If it is desired to program additional key(s) (only up to 8 keys total can be programmed into the IC), refer to Key Programming Using Two
Programmed Keys See: Accessories and Optional Equipment/Antitheft and Alarm Systems/Testing and Inspection/Programming and
