Key Programming Using Diagnostic Equipment - Integrated Keyhead Transmitter (IKT)





NOTE: Vehicles with Integrated Keyhead Transmitters (IKTs) were originally equipped with IKTs manufactured by Huf. Replacement IKTs made by Strattec works correctly, but may look and feel different. It is recommended that IKTs be replaced with the same manufacturer's keys. Rotunda supplies matching keys by the same manufacturer if they are ordered by vehicle.

NOTE: This procedure is used when a customer needs keys programmed into the vehicle and does not have 2 programmed Integrated Keyhead Transmitter (IKT) 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 keycode(s) from the Passive Anti-Theft System (PATS) memory.

NOTE: This procedure erases all programmed ignition keys from the vehicle memory and the vehicle cannot start until 2 keys are programmed to the vehicle. They can be IKT keys, standard PATS keys, or a combination of both. This procedure also erases the IKT Transmitter Identification Codes (TICs) from the Smart Junction Box (SJB), preventing the erased IKTs from operating the Remote Keyless Entry (RKE) functions on the vehicle. 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 can be the customer's original keys. One or both of them can be an IKT or a standard PATS key.

NOTE: This procedure is not necessary if only the PATS transceiver was replaced. Replacement of the transceiver does not erase the PATS keycodes in the IPC.

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 on-screen instructions to ENTER SECURITY ACCESS. For additional information, refer to Anti-Theft Security Access - Integrated Keyhead Transmitter (IKT) Integrated Keyhead Transmitter (IKT).

3. From the scan tool menu select: IGNITION KEY CODE ERASE and follow the on-screen instructions.

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 IPC first. After both keys are programmed into the IPC, then the RKE data transfers from the IPC to the SJB. Until the final data transfer takes place into the SJB, the RKE functions cannot 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 it 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.

9. The vehicle should now start with both ignition keys and the RKE transmitter portion of the IKT key(s) should function.

10. If it is desired to program additional key(s) at a later time (only up to 8 keys total can be programmed into the IPC), refer to Key Programming Using Two Programmed Keys - Integrated Keyhead Transmitter (IKT) Integrated Keyhead Transmitter (IKT) for each additional key that needs to be programmed.
