Remote Keyless Entry (RKE) Lock/Unlock Control - Unlock
The RKE (Remote Keyless Entry) feature provides lock/unlock functions independently of key position, vehicle speed, or transmission position. The RKE (Remote Keyless Entry) feature provides a stepped (if enabled) process for unlocking the doors. Upon receipt of the first request for unlocking the doors, the RKE (Remote Keyless Entry) control feature unlocks the driver door only and provides a long flash of the turn signals. If another unlock request is received within 3 seconds of the first, the RKE (Remote Keyless Entry) feature unlocks all the doors. This feature can be disabled so that all the doors unlock on the first press of the unlock button. Refer to Stepped Unlock Programming Stepped Unlock Programming for programming information.
Remote Keyless Entry (RKE) Lock/Unlock Control - Lock
The RKE (Remote Keyless Entry) feature requests that all of the doors be locked 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 one time. If any door or liftgate is ajar, no flash occurs. As soon as the last door or liftgate is 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 that all of the doors and liftgate are closed and locked. If any door is ajar when the second lock request is received within 3 seconds of the first, the RKE (Remote Keyless Entry) transmitter feature chirps the horn twice without flashing the turn signals to indicate it locked all of the doors but one or more doors or the liftgate is ajar. When the ignition is in the RUN or START position, the turn signal flashes and horn chirp confirmations do not occur.
