Remote Keyless Entry (RKE)

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

The Remote Keyless Entry (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 programming. During PATS programming, the Instrument Cluster (IC) 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. Refer to Key Programming Using Two Programmed Keys or Integrated Keyhead Transmitter (IKT) Key Programming Using Diagnostic Equipment in INTEGRATED KEYHEAD TRANSMITTER (IKT) KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT or ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS) - HYBRID INTEGRATED KEYHEAD TRANSMITTER (IKT) KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT for IKT programming information. Refer to REMOTE KEYLESS ENTRY (RKE) TRANSMITTER PROGRAMMING for keyfob programming information.

Sounds the horn twice when LOCK is pressed twice within 3 seconds, and any door is ajar

The IKT has a normal operating range of 10 m (33 ft).
