RKE (without push button start)

This RKE system uses an IKT 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 latch (manual liftgate) (liftgate button must be pressed twice within 3 seconds).
• open/stop/close the liftgate (power liftgate) (liftgate button must be pressed twice within 3 seconds).
• arm/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 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.

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 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.

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 that 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 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 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 and all of the doors are closed and locked. If the hood, the liftgate 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 or a door is ajar. When the ignition is ON, the turn signal flashes and horn chirp confirmations do not occur.

RKE Transmitter Liftgate Latch Release (manual liftgate) 

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

RKE Transmitter Liftgate Latch Release (power liftgate) 

The RKE transmitter provides a power liftgate open function. The liftgate button must be pressed twice within 3 seconds for the liftgate to open.

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 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.
