Autolock

The autolock feature locks all of the doors after all of the following have occurred:

• All the doors are closed.
• The ignition is on
• The vehicle is shifted into any gear to put the vehicle in motion
• The vehicle attains a speed greater than 20 km/h (12.4 mph)

The autolock feature can be enabled/disabled through the IPC message center.

Auto-Unlock

NOTE: The doors do not auto-unlock if the vehicle has been electronically locked before the driver door is unlocked.

The auto-unlock feature unlocks all of the doors when all of the following conditions have been met:

• All the doors are closed and locked
• The ignition was on
• The vehicle was shifted to PARK and a speed greater than 20 km/h (12.4 mph) was achieved
• The vehicle has come to a stop
• The ignition transitions to accessory or off and, within 10 minutes, the driver door is opened

The auto-unlock feature can be enabled/disabled through the IPC message center.

Door Lock Switch Inhibitor

The door lock switch inhibitor is a BCM -controlled feature that prevents the interior door lock control switches from functioning when the following conditions are met:

• The feature is enabled using the IPC
• The ignition is off
• The vehicle is not in accessory delay mode
• The vehicle has come to a stop
• The vehicle has been locked for more than 20 seconds using the key (RKE transmitter), mechanical key, or interior door lock control switch.

If the interior door lock control switches are pressed while inhibited, a chime sounds and “Switches Inhibited Security Mode” is displayed on the IPC message center.

The feature is disabled when any door is opened using the interior door handle.

For more information, refer to “Door Lock Switch Inhibitor” in the Owner's Literature.

Fuel Filler Door Lock (If Equipped)

Upon a command from the BCM , the fuel filler door actuator unlocks the fuel filler door in conjunction with the driver’s door latch.

The fuel filler door actuator locks the fuel filler door when the vehicle has been locked using the key (RKE transmitter), mechanical key, or interior door lock control switches.

Panic Alarm

The panic alarm feature provides audible and visual alarms which are evident from the exterior of the vehicle. When the panic alarm button is initially pressed, the panic alarm feature requests that the turn signals flash and the horn sounds for up to 3 minutes or 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 status changes from 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.

Passive Entry

The passive entry feature unlocks or locks the doors, fuel filler door (if equipped), and tailgate without having to use a mechanical key blade or the RKE transmitter feature.

With a programmed passive key within 1m (3.28ft) outside a door, touch the lock or unlock sensor on the exterior door handle. The doors lock or unlock depending upon which sensor was touched on the handle. The unlock sensor is located on the inside of the handle and the lock sensor is located on the outside top face of the handle.

With the 2-staged unlock feature enabled, the driver front door passive entry feature unlocks the driver door and fuel filler door (if equipped). With the 2-staged unlock feature disabled, the driver front door passive entry feature unlocks all doors, fuel filler door (if equipped), and tailgate. The passive entry feature always locks all doors, fuel filler door (if equipped), and tailgate when the lock sensor is touched for a half second. The passenger front door entry feature always locks or unlocks all doors, fuel filler door (if equipped), and tailgate.

When the BCM detects a lock or unlock sensor is touched on an exterior front door handle or the tailgate release button is pressed, it activates the corresponding low frequency antenna in the corresponding exterior front door handle and inside the cargo area. The low frequency antenna sends out a signal to the passive key. The low frequency signal activates the passive key and the passive key sends a high frequency signal back to the BCM . If requested action is performed if the BCM detects a programmed passive key.

With a programmed passive key within 1m (3.28ft) of the tailgate, press the release button to release the tailgate.

Power Door Locks

The BCM controls the door locks by using a series of relays (driver door unlock/passenger doors unlock/all doors lock) integrated within it. When the relays are not energized, ground is provided on both circuits to the lock motors within the latches. When an unlock relay energizes, voltage is provided to one side of the lock motor to unlock the door(s). When the lock relay energizes, the polarity is reversed and the motors lock the doors.

For vehicles with passenger door one-touch windows, the DDM and PDM send voltage signals to the door lock control switches. When a door lock control switch is pressed, the voltage signal is routed to ground, indicating a request to lock/unlock the doors. When the DDM or the PDM detects a lock or unlock request, a message is sent over the CAN to the BCM to lock or unlock the doors.

In the event of a power door lock failure, the doors can be individually locked through the manual door lock. The manual door lock is located on the rear edge of the door just above the door latch opening. For the doors on the left side of the vehicle, insert a key and turn clockwise to lock. For the doors on the right side of the vehicle, insert a key and turn counterclockwise to lock.

Additionally, there is a door lock LED indicator located on each door lock control switch. The indicators provide lock/unlock indication for all doors. They illuminate when the doors are locked and are off when the doors are unlocked. For detailed information of the door lock LED indicators,
Refer to: Handles, Locks, Latches and Entry Systems - System Operation and Component Description (501-14 Handles, Locks, Latches and Entry Systems, Description and Operation).

Based on input from the door lock control switches, the passive entry system and the RKE transmitter, the BCM unlocks the driver door, unlocks all the doors or locks all the doors.

The exterior lamps and horn provide visual and audible feedback when unlocking and locking the doors under certain circumstances.

RKE

The RKE feature is controlled by the BCM . When a button is pressed ( IKT or passive key), the Transmitter Identification Code (TIC) and RKE command is received by the BCM . If the BCM detects a programmed key, it carries out the command by controlling the door locks or activating the horn or turn signals as required.

The RKE system can be used perform any of the following:

• Unlock the driver door
• Unlock all doors
• Lock all doors
• Arm/disarm the perimeter alarm (if equipped)
• Activate/deactivate the panic alarm
• Global open and close (if equipped) the windows. For additional information, refer to “Global Opening and Closing” in the Owner's Literature.
• Configure the staged unlock programming (2-stage unlock or global unlock)

The RKE transmitters for an IKT have a normal operating range of 30m (98.43ft) in an open air, no obstruction environment.

The RKE transmitters for a passive key have a normal operating range of 30m (98.43ft) in an open air, no obstruction environment.

The RKE transmitters and the BCM 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 a RKE transmitter button is pressed.

The message center displays Key Battery Low Replace Soon when the battery in the key needs to be replaced.

With the 2-stage unlock feature enabled, the first request for unlocking the doors unlocks only the driver door and provides a long flash of the turn signals. If another unlock request is received within 3 seconds, all the doors are unlocked. This feature can be disabled so that all the doors unlock on the first press of the unlock button (global unlock).
Refer to: Staged Unlock Programming (501-14 Handles, Locks, Latches and Entry Systems, General Procedures).
Vehicles come from the factory with the 2-stage unlock feature disabled (single press unlocks all doors).

Smart Unlock (Without Push-Button Start)

The smart unlock feature prevents the doors from electronically locking with the key in the ignition lock cylinder. When the BCM receives a lock command from a door lock control switch and the key is detected in the ignition lock cylinder with the driver or front passenger door open, the BCM commands the doors to unlock.

To override the smart unlock feature and intentionally lock the doors with the key in the ignition lock cylinder, close all doors and lock the vehicle by pressing the lock button on another programmed IKT , or with another key using the driver door lock cylinder.

Smart Unlock (With Push-Button Start)

The smart unlock feature prevents the doors from electronically locking when a passive key is left inside the vehicle. When the doors are locked and then closed, the interior of the vehicle is scanned for a passive key. If a passive key is detected inside the vehicle when the doors are locked and closed, the doors unlock.

To override the smart unlock feature, lock the doors using the driver door lock cylinder or another programmed passive key.
