RKE (with push button start): Notes

This RKE system uses a passive key. 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.
• open/stop/close the liftgate (liftgate button must be pressed twice within 3 seconds).
• arm/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 (if equipped).

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 a 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 valid 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 ON.
