- All the doors are closed
- The ignition switch is in the RUN position
- The vehicle is shifted into any gear, putting the vehicle in motion
- The vehicle attains a speed greater than 20 km/h (12 mph)
The autolock feature repeats when:
- any door is opened then closed with the ignition in the RUN mode,
- the vehicle speed is 15 km/h (9 mph) or slower,
- and then the vehicle then attains a speed greater than 20 km/h (12 mph).
Auto-Unlock
NOTE: The doors do 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 following sequence of conditions are met:
- the ignition is in the RUN mode,
- all the doors are closed,
- the vehicle has been in motion at a speed greater than 20 km/h (12 mph),
- the vehicle then comes to a stop,
- the ignition is switched to the OFF or ACC mode,
- and the driver door is opened within 10 minutes of the ignition being switched to the OFF, LOCK or ACC mode.
Smart Unlock
The smart unlock feature prevents the doors from electronically locking when an IA key is left inside the vehicle. When the Remote Function Actuator (RFA) module receives a lock command from a door lock control switch, and an IA key is inside the vehicle with one of the doors open, the RFA module commands all the doors to unlock and the horn chirps. To override the smart unlock feature and intentionally lock a key in the vehicle, close all of the doors and lock the vehicle using the keyless entry keypad or press the lock button on another IA key, or lock the doors manually with the lock rod before closing the door.
Driver Door Intelligent Access (IA) Feature
The driver door IA feature allows the driver door to be unlocked without having to use the door lock cylinder or the Remote Keyless Entry (RKE) transmitter feature on the IA key. With a programmed IA key within 1 m (3 ft) outside the driver door, touch any button on the keyless entry keypad, and the driver door unlocks with stepped unlock enabled. If stepped unlock is disabled all the doors unlock when using the driver door IA feature. Refer to Stepped Unlock Programming Stepped Unlock Programming for programming information.
Liftgate Intelligent Access (IA) Feature
The liftgate IA feature allows the liftgate to be opened without having to use the interior liftgate switch or the keyless entry keypad. With a programmed IA key within 1 m (3 ft) outside the liftgate, press the liftgate release button on the rear bumper cover, and the liftgate opens.
Remote Keyless Entry (RKE)
The RKE system uses an IA key. The IA key 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 IA key programming. During IA key programming, the RFA module obtains the Transmitter Identification Code (TIC) from the IA key.
The RFA module accepts programming of up to 4 IA keys. Refer to Key Programming Using Two Programmed Keys - Intelligent Access (IA) or Key Programming Using Diagnostic Equipment - Intelligent Access (IA) in Anti-Theft - Passive Anti-Theft System (PATS) Key Programming Using Diagnostic Equipment - Intelligent Access (IA) for key programming information.
The IA key initiates the following electronic system functions:
- Unlocks the LH front door
- Unlocks all doors
- Locks all doors
- Opens/closes the liftgate
- Activates/deactivates the panic alarm
- Provides a long flash of the turn signals when UNLOCK is pressed
- Commands the interior lamps on (when unlocking) and off (when locking)
- 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 RKE transmitter in the IA key 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 mode, 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 and provides a long flash of the turn signals. 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 a 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 once. If any door or liftgate is ajar, no flash occurs and the horn chirps twice on the second press. 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 the doors are closed and locked. If any door or liftgate 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 one or more doors are ajar. When the ignition is in the RUN or START mode, the turn signal flashes and horn chirp confirmations do not occur.
Remote Keyless Entry (RKE) Liftgate
The RKE feature provides liftgate open/close function independently of ignition status. To open or close the liftgate, press the liftgate button twice within 3 seconds.
Remote Keyless Entry (RKE) Memory Seat Feature
The RKE feature provides a memory seat feature. Up to 2 RKE transmitters can be associated with memory settings. When the UNLOCK button on an RKE transmitter is pressed, the driver seat, adjustable steering column, adjustable pedals, and exterior mirrors move to the desired memory position (the seat, steering column, pedal, and mirror position corresponds to the RKE transmitter being used). This feature can be enabled/disabled. Refer to Remote Memory Activation Remote Memory Activation and Remote Memory Deactivation Remote Memory Deactivation for programming information.
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 RKE transmitter whenever the ignition is in the OFF mode. 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 RKE transmitter panic button
- The ignition is switched out of the OFF mode
- A period of 2 minutes and 45 seconds has elapsed since the initial activation
Keyless Entry Keypad
The keypad provides a method for customers to access their vehicle. The keypad feature:
- Locks all doors

The keypad feature operates independently of ignition mode, vehicle speed, or transmission position. When a keypad button is touched or when the courtesy lighting is illuminated, 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 is programmed with a 5-digit permanent entry code. This code is provided to the customer through a wallet card in the Owner's Literature. In addition, this code is available using 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 RFA module accepts the programming of 3 personal entry codes. Refer to Keyless Entry Keypad Code Programming Testing and Inspection for programming information.
