System Operation: RKE

The RKE system uses an IKT. The IKT incorporates both the PATS and the RKE transmitter functions in a single device.

In addition to the IKT, conventional RKE transmitters (key fobs) can be programmed to the vehicle the RKE transmitters can be used to:

• unlock the driver door.
• unlocks all doors.
• locks all doors.
• release the liftgate/luggage compartment lid latch.
• arms/disarm the perimeter alarm (if equipped).
• activate/deactivate the panic alarm.
• provide a visual confirmation when the unlock button is pressed (a long 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 (sounds the horn twice).

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 a RKE transmitter, the Transmitter Identification Code (TIC) and the RKE command are received by the internal BCM antenna. If the BCM detects a valid programmed RKE transmitter, the BCM carries out the command by activating the power door locks, releasing the liftgate/luggage compartment lid latch or activating the horn or turn signals as required.

RKE Transmitter Unlock 

The RKE feature provides a staged (if enabled) process for unlocking the doors. Upon receipt of the first request for unlocking the doors, the RKE control feature unlocks only the driver door and provides a long flash of the turn signals. If another unlock request is received within 3 seconds of the first, all the doors are unlocked. This feature can be disabled so all the doors unlock on the first press of the unlock button. To enable/disable this feature, Refer to: Staged Unlock Programming 

RKE Transmitter Lock 

The RKE feature requests all of the doors be locked when the lock button is pressed. On any press of the lock button with all doors closed, the doors lock and the turn signals flash once. If the hood, the liftgate/luggage compartment lid or any door is ajar, no flash occurs. As soon as all the openings are closed, the turn signals flash.

If 2 presses of the lock button are received within 3 seconds, the horn chirps once and the turn signals flash to indicate the hood, the liftgate/luggage compartment lid and all of the doors are closed and locked. If the hood, the liftgate/luggage compartment lid or any door is ajar or does not lock when the second lock request is received within 3 seconds of the first, the RKE transmitter feature chirps the horn twice without flashing the turn signals to indicate it locked all of the doors but the hood, the liftgate/luggage compartment lid or a door is ajar or did not lock. When the ignition is on, the turn signal flashes and horn chirp confirmations do not occur.

RKE Transmitter Liftgate/Luggage Compartment Lid Release 

The RKE transmitter feature provides a liftgate/luggage compartment lid release function. The liftgate/luggage compartment lid button must be pressed twice within 3 seconds for the liftgate/luggage compartment lid latch to release.

Panic Alarm 

The panic alarm feature provides audible and visual alarms which are evident from the exterior of the vehicle. The panic alarm feature requests that the turn signals flash and the horn sounds until deactivation. The flashing of the outputs occurs simultaneously.

The panic alarm can only be activated when the key is not in the ignition lock cylinder. This feature is disabled at all other times. Deactivation of an active panic alarm is accomplished when:

• a second press of the RKE transmitter panic button is detected.
• the ignition is switched out of off.
• a period of 2 minutes and 45 seconds has elapsed since the initial activation.

The panic alarm cannot be deactivated during the first 5 seconds of activation to avoid unintentional deactivation.
