RKE (without push button start): Notes

This RKE system uses an Integrated Keyhead Transmitter (IKT). The Integrated Keyhead Transmitter (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 Integrated Keyhead Transmitter (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.
