Remote Keyless Entry (RKE): Notes

WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

The RKE system uses an Integrated Keyhead Transmitter (IKT). The IKT incorporates both the Passive Anti-Theft System (PATS) functions and the RKE transmitter functions in a single device.

The RKE transmitter is programmed automatically during PATS key programming. During PATS key programming, the Instrument Panel Cluster (IPC) obtains the Transmitter Identification Code (TIC) from the IKT and sends the TIC data over the Medium Speed Controller Area Network (MS-CAN) to the SJB .

The SJB accepts programming of up to 4 IKTs . In addition to the IKTs , 4 conventional keyfobs can also be programmed to the vehicle if requested by the customer. For information on programming the IKTs , refer to KEY PROGRAMMING USING TWO PROGRAMMED KEYS or INTEGRATED KEYHEAD TRANSMITTER (IKT) KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT or INTEGRATED KEYHEAD TRANSMITTER (IKT) KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT . For information on programming the conventional keyfobs, refer to REMOTE KEYLESS ENTRY (RKE) TRANSMITTER PROGRAMMING .
