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 Medium Speed Controller Area Network (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.
