RKE (without push button start)

The Integrated Keyhead Transmitter (IKT) key incorporates both the PATS  and the RKE  transmitter functions in a single device.

The RKE  transmitters can be used to:

• unlock the driver door.
• unlock all doors.
• lock all doors.
• release the liftgate/luggage compartment lid latch.
• arms/disarm the perimeter alarm.
• activate/deactivate the panic alarm.
• provide a visual confirmation when the unlock button is pressed (a long flash of the turn signals).
• provide a visual confirmation when the lock button is pressed (a short flash of the turn signals).
• provide an audible confirmation when the lock button is pressed twice within 3 seconds with all the doors closed (sounds the horn once).
• provide an audible confirmation when the lock button is pressed twice within 3 seconds and any door is ajar or a door is not locked.
• remotely start the vehicle.

The RKE  transmitters have a normal operating range of 20 m (65.62 ft).

The RKE  feature is controlled by the BCM  . When a button is pressed on an Integrated Keyhead Transmitter (IKT), the Transmitter Identification Code (TIC) and RKE  command are received by the internal BCM  antenna. If the BCM  determines that it is a valid and programmed Transmitter Identification Code (TIC), the BCM  carries out the command by controlling the door locks or activating the horn or turn signals as required.

The RKE  transmitters and the BCM  also utilize a rolling code to prevent the code from being captured by a code grabber. The system advances the counter in the RKE  transmitter and the BCM  every time an RKE  transmitter button is pressed.
