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 switch in the vehicle. The power door locking system functions independently of ignition status or vehicle speed.
Autolock
NOTE: The autolock feature is not available on vehicles equipped with a manual transmission.
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 either a forward or reverse 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).
This feature can be activated/deactivated. Refer to Autolock and Auto-Unlock Programming Autolock and Auto-Unlock Programming for programming information.
Auto-Unlock
NOTE: The auto-unlock feature is not available on vehicles equipped with a manual transmission.
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's door is opened within 10 minutes of the ignition being switched to LOCK or ACC.
This feature can be activated/deactivated. Refer to Autolock and Auto-Unlock Programming Autolock and Auto-Unlock Programming for programming information.
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 conventional 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 or Antitheft and Alarm Systems for IKT programming information. Refer to Remote Keyless Entry (RKE) Transmitter Programming Transmitter for keyfob programming information. Using Two Programmed Keys Using Diagnostic Equipment
The IKT initiates the following electronic system functions:
- Unlocks the LH front door
- Unlocks all doors
- Locks all doors
- Releases the liftgate glass
- Activates/deactivates the panic alarm
- Commands the interior lamps on (when unlocking) and off (when locking)
- Provides a long flash of the turn signals when UNLOCK is pressed
- Sounds the horn once when LOCK is pressed twice within 3 seconds, and the doors are closed
- Sounds 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 key position, vehicle speed, or transmission position. The RKE feature provides a stepped process for unlocking the doors. Upon receipt of the first request for unlocking the doors, the RKE control feature requests the SJB to unlock 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 feature requests the SJB to unlock all the doors. This feature can be changed to global 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 the doors closed, the SJB provides one flash of the turn signals. If any door is ajar, no flash occurs. As soon as the last door is closed, the SJB provides the flash of the turn signals. 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 is ajar when the second lock request is received within 3 seconds of the first, the RKE transmitter feature requests the SJB to chirp the horn twice without flashing the turn signals to indicate it locked all the doors but one or more doors are ajar. When the key is in the RUN position, the turn signal flashes and horn chirp confirmations do not occur.
Remote Keyless Entry (RKE) Liftgate Glass Release
The RKE feature provides liftgate glass release function independently of key position. The liftgate glass release button must be pressed twice within 3 seconds for the liftgate glass to release.
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 (If Equipped)
The keyless entry keypad performs the following functions:
- Unlocks the driver door
- Unlocks all the doors
- Locks all doors
- Releases the liftgate glass
- Programs/erases the customer key code
- Enables/disables auto-unlocking
- Enables/disables autolocking
- Illuminates the keyless entry keypad lamp and issues illuminated entry on/off requests
The keypad feature operates independently of key position status, vehicle speed, or transmission position. When a keypad button is pressed, 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 package. 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.
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 (stepped unlock has to be enabled), enter either the factory set code or a personal code; each digit must be pressed within 5 seconds of the prior digit. If the stepped unlock is disabled, all of the doors will unlock upon entry of the factory set or personal code. Refer to Stepped Unlock Programming Stepped Unlock Programming for programming information.
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 when the stepped unlock is enabled. If the stepped unlock is disabled, all the doors will unlock upon the entry of the factory set or personal code.
Releasing the Liftgate Glass
To release the liftgate glass, enter the factory set code or a personal code (driver door unlocks) and press the 5/6 button within 5 seconds.
Anti-Scan Feature
To provide added security, the keypad is disabled for one minute after 35 button presses without a valid entry code being entered. The keypad flashes during this one-minute mode with all functionality disabled except for 7/8 and 9/0 still being allowed to lock the vehicle.
Anti-scan is turned off after one minute of keypad inactivity.
