Power Lock/Unlock
The power lock/unlock feature requests all of the vehicle doors locked or unlocked upon a customer request from either interior door lock control switch in the vehicle. The power door locking system functions independently of ignition status or vehicle speed.
Autolock
The autolock feature locks all the doors when all the doors (including the liftgate) are closed, the key is in the RUN position, the transmission is in any gear, and the vehicle speed is greater than 20 km/h (12 mph).
The autolock feature repeats when any door is opened then closed while the ignition is still in the RUN position, the vehicle speed is 15 km/h (9 mph) or slower, and the vehicle then attains a speed greater than 20 km/h (12 mph).
Auto-Unlock
NOTE: The doors will not auto-unlock if the vehicle has been electronically locked before the driver door is opened.
The auto-unlock feature unlocks all the doors when the ignition is in the RUN position, all the doors are closed, and the vehicle has been in motion at a speed greater than 20 km/h (12 mph). The vehicle then comes to a stop and the ignition is switched to LOCK or ACC, and the driver door is opened within 10 minutes of the ignition being switched to OFF, LOCK or ACC.
Smart Unlock
The smart unlock feature prevents the doors from locking with the key in the ignition lock cylinder. When the SJB receives a lock command from a door lock control switch, and the key is in the ignition lock cylinder with one of the front doors open, the SJB commands all the doors to unlock.
Remote Keyless Entry (RKE)
The Remote Keyless Entry (RKE) system uses an Integrated Keyhead Transmitter (IKT). The IKT incorporates both the Passive Anti-Theft System (PATS) functions and the RKE transmitter functions in a single device.
The RKE transmitter is programmed automatically during PATS programming. During PATS programming, the Instrument Cluster (IC) obtains the Transmitter Identification Code (TIC) from the IKT and sends the TIC data over the Medium Speed Controller Area Network (MS-CAN) to the SJB.
The SJB accepts programming of up to 4 IKTs. In addition to the IKTs, 4 standard keyfobs can also be programmed to the vehicle if requested by the customer. Refer to Key Programming Using Two Programmed Keys or Integrated Keyhead Transmitter (IKT) Key Programming Using Diagnostic Equipment in Antitheft and Alarm Systems for key programming information Using Two Programmed Keys Using Diagnostic Equipment. Refer to Remote Keyless Entry (RKE) Transmitter Programming Transmitter for key fob programming information.
Without Power Liftgate
With Power Liftgate
The IKT initiates the following electronic system functions:
- Unlock the LH front door
- Unlock all doors
- Lock all doors
- Activate/deactivate the panic alarm
- Commands the interior lamps on (when unlocking) and off (when locking)
- Sound the horn once when LOCK is pressed twice within 3 seconds, and the doors are closed
- Sound the horn twice when LOCK is pressed twice within 3 seconds, and any door is ajar
The IKT has a normal operating range of 10 m (33 ft).
Remote Keyless Entry (RKE) Lock/Unlock Control - Unlock
The RKE feature provides lock/unlock functions independently of ignition state, vehicle speed, or transmission position. The RKE feature provides a stepped (if enabled) process for unlocking the doors. Upon receipt of the first request for unlocking the doors, the RKE control feature unlocks the driver door only. If another unlock request is received within 3 seconds of the first, the RKE feature unlocks all the doors. This feature can be changed to 1-step unlock, 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 feature requests that all 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 1 time. If any door or luggage compartment lid is ajar, no flash occurs and the horn will chirp twice. As soon as the last door or luggage compartment lid 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 the doors are closed and locked. If any door or luggage compartment lid is ajar when the second lock request is received within 3 seconds of the first, the RKE transmitter feature requests the horn chirp twice without flashing the turn signals to indicate it locked all the doors but 1 or more doors are ajar. When the ignition is in the RUN or START state, the turn signal flashes and horn chirp confirmations do not occur.
Remote Keyless Entry (RKE) Power Liftgate Release
The RKE feature provides liftgate release function independently of key position. The vehicle speed must be less than 5 km/h (3 mph) for this function to work.
Remote Keyless Entry (RKE) Memory Seat Feature
The RKE feature provides memory seat feature. When the unlock button on an IKT is pressed the drivers seat, adjustable pedals, and exterior mirrors move to the desired memory position (the seat, pedal, and mirror position corresponds to the IKT being used). This feature can be enabled/disabled. Refer to Remote Memory Activation Remote Memory Activation and Remote Memory Deactivation Remote Memory Deactivation.
Panic Alarm
The panic alarm feature provides audible and visual alarms which are evident from the exterior of the vehicle. The panic alarm feature requests that the turn signals are flashed and the horn sounds until deactivation. The flashing of the outputs occurs simultaneously. Activation of the panic alarm is accomplished by pressing the panic button on an IKT whenever the key is in the OFF position. At all other times this feature is disabled. Deactivation of an active panic alarm is accomplished by any of the following actions:
- A second press of the IKT panic button
- The key is switched out of the OFF position
- A period of 2 minutes and 45 seconds has elapsed since the initial activation
Keyless Entry Keypad
The keypad, is integrated into the B-pillar applique on the driver door, and provides a method for customers to access their vehicle without an IKT. The keypad feature:
- Locks all doors
- Unlocks the driver door (with stepped unlock enabled)
- Unlocks all doors
- Command the interior lamps on (when unlocking) and off (when locking)
- Programs/erases the customer key code
- Enables/disables auto-unlocking
- Enables/disables autolocking
- Recalls memory seat/power mirror positions (if equipped)
The keypad feature operates independently of key position status, vehicle speed, or transmission position. The keypad is touch sensitive and will not work if gloves are worn. When a keypad button is touched, the keypad buttons illuminate to provide better visibility. If the lock all doors command is entered or 5 seconds have elapsed since the last button press, the illumination is turned off.
Each vehicle equipped with a keypad is programmed with a 5-digit entry code. This code is provided to the customer through a wallet card in the Owner's Literature. In addition, this code is available through a scan tool and is also printed on the SJB label. When entering codes, each digit must be entered within 5 seconds of the previous button press. The SJB accepts the programming of 3 personal entry codes. Refer to Keyless Entry Keypad Code Programming Testing and Inspection for programming information.
Locking the Doors with the Keyless Entry Keypad System
It is not necessary to enter the factory set or personal code prior to locking all doors. To lock all doors, press the 7/8 and 9/0 controls at the same time.
Unlocking the Doors with the Keyless Entry Keypad System
To unlock the driver door (if stepped unlock is disabled), enter either the factory set code or a personal code; each digit must be pressed within 5 seconds of the prior digit. The interior lamps illuminate.
To unlock all doors, enter either the factory set code or a personal code (driver door unlocks) and press the 3/4 button within 5 seconds. This feature can be changed to 1-step unlock, so that all the doors unlock on the entry of the factory set or personal code. Refer to Stepped Unlock Programming Stepped Unlock Programming for programming information.
Keyless Entry Keypad Memory Seat Feature
The keypad provides memory seat feature. The feature is associated with personal codes and positions the driver seat, adjustable pedals, and exterior mirrors to the Driver 1 or Driver 2 memory setting. Refer to Keyless Entry Keypad Code Programming Testing and Inspection for programming information.
Anti-Scan Feature
To provide added security, the keypad is disabled for 1 minute after 35 button presses without a valid entry code being entered. The keypad flashes during this 1-minute mode with all functionality disabled except for the 7/8 and 9/0 buttons still being allowed to lock the vehicle.
