RKE (with push button start)

The passive 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 passive key supplies a signal to the Radio Frequency (RF) receiver when any RKE button is pressed. The Radio Frequency (RF) receiver interprets the information from the passive key and sends a signal to the RFA module. If the RFA module determines that it is a programmed key, it sends a message over the MS-CAN to the BCM.

The RKE transmitters and the RFA module 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 RFA module every time a RKE transmitter button is pressed.

The RKE feature switches off after 27 days of inactivity to conserve battery power. The RKE feature enables when the ignition is switched to RUN.

RKE Unlock 

The RKE feature provides a stepped (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 that all the doors unlock on the first press of the unlock button. To enable/disable this feature, Refer to: Staged Unlock Programming 

RKE Lock 

The RKE feature requests that all of the doors lock 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 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 twice 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 unlocked 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. When the ignition is ON, the turn signal flashes and horn chirp confirmations do not occur.

RKE Liftgate/Luggage Compartment Lid Release 

The RKE transmitter provides a liftgate/luggage compartment lid release function. The liftgate/luggage compartment lid release 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 ignition is OFF. 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 have elapsed since the initial activation.

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

Remote Start (if equipped) 

The factory-installed remote start allows the vehicle to be remotely started from outside the vehicle.

To remotely start the vehicle, the buttons on the passive key must be pressed within 3 seconds of each other. Press the lock button once and then the remote start button twice.

The vehicle does not remote start if any of the following conditions are present:

• The feature is disabled using the message center.
• The hood is not closed.
• The vehicle is not in PARK.
• A powertrain system DTC is present, illuminating the service engine soon indicator.
• The ignition is on.
• The alarm system is triggered.
• The vehicle battery voltage is low.
• Two remote starts have already been attempted within the past hour.

For additional information regarding the remote start system, refer to the Owner's Literature.
