Power Lock/Unlock
The power lock/unlock feature requests all of the vehicle doors locked or unlocked upon a customer request from either door lock control 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 are closed, the key is in the ON position, the transmission is in either a forward or reverse gear, and the vehicle speed is greater than 20 km/h (12 mph) for 2 seconds or longer.
The autolock feature repeats when any door is opened then closed while the ignition is still in the ON 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) for 2 seconds or longer.
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 is disabled on vehicles equipped with a manual transmission.
The auto-unlock feature unlocks all the doors when the ignition is in the ON 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 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 (only), and the key is in the ignition lock cylinder with one of the front doors open, the SJB commands the doors to unlock.
The vehicle can still be locked with the ignition key in the ignition cylinder by locking the doors with the push button rods, the door lock cylinder or an RKE command from an integrated key or the keyless entry keypad.
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 SJB accepts programming of up to 4 IKTs. In addition to the IKTs, 6 standard keyfobs can also be programmed to the vehicle if requested by the customer. For information on programming the IKTs, refer to Antitheft and Alarm Systems. For information on programming the keyfobs, refer to Remote Keyless Entry Transmitter Programming. Transmitter
The IKT performs the following functions:
- Unlock the driver door
- Unlock all doors
- Lock all doors
- Release the luggage compartment lid latch
- Arm/disarm the perimeter alarm (if equipped)
- Activate/deactivate the panic alarm
- Command the interior lamps on (when unlocking) and off (when locking)
- Recall the memory seat position associated with a particular remote entry device (when enabled)
- 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 maximum operating range of 10 m (33 ft).
The IKT can be programmed using a scan tool during PATS key programming. Refer to Antitheft and Alarm Systems.
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 (if enabled) 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. 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 configured 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
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 SJB provides 1 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 chirp the horn twice without flashing the turn signals to indicate it locked all the doors but 1 or more doors are ajar. When the key is in the ON or START position, the turn signal flashes and horn chirp confirmations do not occur.
Remote Keyless Entry (RKE) Luggage Compartment Lid Release
The RKE feature provides luggage compartment lid release function independently of key position. The luggage compartment lid release button must be pressed twice within 3 seconds for the luggage compartment lid to release.
Panic Alarm
NOTE: The panic alarm activation can be configured using a scan tool from a single button press to press and hold. Refer to Information Bus (Module Communications Network).
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 integrated keyhead transmitter (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 keyless entry keypad performs the following functions:
- Unlock the driver door
- Unlock all the doors
- Lock all doors
- Enables/disables auto-unlocking
- Enables/disables autolocking
- Arm/disarm the perimeter alarm (if equipped)
- Recall the memory seat position associated with a particular customer key code (when enabled)
- Release the luggage compartment lid latch
- Programs/erases the customer key code
- 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. 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, 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.
To open the luggage compartment, 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 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 7/8 and 9/0 still being allowed to lock the vehicle.
Anti-Scan is turned off after 1 minute of keypad inactivity.
Perimeter Lighting Feature
NOTE: On vehicles with autolamps, the perimeter lighting feature does not activate in daylight conditions.
Vehicles equipped with perimeter lighting can have this feature activated or deactivated. For information on programming the perimeter lighting feature, refer to Perimeter Lighting Feature Programming. Perimeter Lighting Feature Programming

Door Lock Control Switch Inhibit
As a theft deterrent, the door lock control switches and the luggage compartment lid release switch can be disabled 20 seconds after the key is turned to the OFF position and the vehicle is locked using the RKE transmitter, the keyless entry keypad, or when the driver door is opened, and the power locks are locked with the door lock control switch, then the driver door is closed.
The door lock control switch is enabled when the vehicle is unlocked by one of the following methods:
- The keyless entry keypad
- The RKE transmitter
- Any door is opened from the vehicle's interior
- The key is turned to the ON position
The door lock control switch inhibit feature is configured off by default. To enable this feature, refer to the Owner's Literature.
