Lock Cylinders
Individual lock cylinders are repaired by discarding the inoperative lock cylinder and building a new lock cylinder using the appropriate lock repair package. The lock repair package includes a detailed instruction sheet to build the new lock cylinder to the current key code of the vehicle.
Autolock
The autolocking function automatically locks all doors when all of the following conditions are concurrently met during the current key cycle:
- All the doors are closed
- The autolocking function is active
- The ignition switch is in the RUN position
- The transmission is in any forward gear
- The vehicle speed exceeds 5 km/h (3 mph)
After the initial activation of autolocking and at least one door has been opened, autolocking is activated again if the following conditions are concurrently met:
- All the doors are closed
- The autolocking function is active
- The ignition switch is in the RUN position
- The transmission is in any forward gear
- The vehicle speed exceeds 5 km/h (3 mph)
Auto-Unlock
The auto-unlocking function automatically unlocks all the doors when the following conditions are met:
- The vehicle speed has exceeded 5 km/h (3 mph) then dropped to 0 km/h (0 mph)
- The key is turned to the OFF or ACC position
- The driver door is opened within 10 minutes of the key being turned to the OFF or ACC position
The auto-unlock feature is cancelled if the doors are locked with the door lock control switch or the RKE transmitter within the 10-minute active window. After the 10-minute active window expires, the auto-unlock feature does not unlock the doors if the driver door is opened.
Smart Unlock
The smart unlock feature prevents the driver door from locking with the key in the ignition lock cylinder. When the Driver Door Module (DDM) receives a LOCK command from a door lock control switch, and the key is in the ignition lock cylinder with the driver door open, the DDM commands all the doors to lock, then unlock.
Unlock Inhibit Feature
The unlock inhibit feature disables the interior door lock control switches and the interior luggage compartment lid release button when the perimeter alarm becomes armed. Once the interior switches are disabled, they can only become active once the perimeter alarm is disarmed.
Remote Keyless Entry (RKE)
The RKE system consists of the following components:
- DDM
- Tire Pressure Monitoring System (TPMS)/ RKE antenna (located on the RH C-pillar)
- RKE transmitter
The RKE transmitter initiates the following electronic system functions:
- Releases the luggage compartment lid
- Unlocks the driver door
- Unlocks all doors
- Locks all doors.
- Arms/disarms the perimeter alarm or inhibits the alarm for the luggage compartment
- Activates/deactivates the panic alarm
- 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 hood, luggage compartment lid and doors are closed
- Sounds the horn twice when LOCK is pressed twice within 3 seconds if any door, hood or luggage compartment lid is not closed
The RKE transmitter has a normal operating range of 10 m (33 ft).
The RKE transmitters can be programmed using a scan tool or by using the ignition lock cylinder method. Refer to Remote Keyless Entry (RKE) Transmitter Programming Remote Keyless Entry (RKE) Transmitter Programming for programming information.
Remote Keyless Entry (RKE) Lock/Unlock Control - Unlock
The RKE transmitter feature provides lock/unlock functions independently of the key position and the vehicle speed. The RKE transmitter feature provides a 2-step process for unlocking the doors. Upon receipt of the first request for unlocking the doors, the remote control feature requests the DDM to unlock the driver door only. If another unlock request is received within 3 seconds of the first, the RKE transmitter feature requests that all doors be unlocked.
Remote Keyless Entry (RKE) Lock/Unlock Control - Lock
The RKE transmitter feature requests that all the doors be locked when the LOCK button on the RKE transmitter is pressed. On any press of the LOCK button with all doors closed, the RKE feature requests one flash of the parking lamps. If any door is ajar, no flash occurs, indicating the DDM locked all the doors but one or more doors are ajar. When the last door is closed, the vehicle provides one flash of the parking lamps. If 2 presses of the LOCK button are received within 3 seconds, the horn chirps once, and the parking lamps flash 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 horn chirp twice without flashing the parking lamps to indicate it locked all the doors but one or more doors are ajar. When the key is in the RUN or START position, no parking lamp flashes or horn chirp confirmations occur.
Remote Keyless Entry (RKE) Luggage Compartment Lid Release
The RKE feature provides a luggage compartment lid release. The feature operates regardless of key position. The feature is inhibited when the vehicle speed is 5 km/h (3 mph) or greater.
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 parking lamps flash and the horn sounds until deactivation. The flashing of the outputs occurs simultaneously. The panic alarm is activated by pressing the PANIC button on an RKE transmitter when the key is in the OFF position, or the key is out of the ignition lock cylinder. At all other times this feature is disabled. The panic alarm is deactivated by: a second press of the RKE transmitter PANIC button, the key is switched out of the OFF position, or a period of 2 minutes and 45 seconds has elapsed since the initial activation.
Keyless Entry Keypad
The keypad does not operate if the driver door is ajar.
The keypad provides a method for the customer to access the vehicle without a key or RKE transmitter. The keyless entry keypad feature:
- locks all doors.
- unlocks only the driver door.
- unlocks all doors.
- programs/erases the customer key code.
- enables/disables autolocking and auto-unlocking.
- arms/disarms the perimeter alarm.
- releases the luggage compartment lid latch.
The keypad feature operates independently of the key position status. When a keypad button is pressed, the keypad buttons illuminate to provide better visibility. If the 7/8 and 9/0 buttons are pressed simultaneously to lock all doors 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 factory set entry code. This code is provided to the customer on a wallet card. In addition, this code is available through a scan tool. When entering codes, each digit must be entered within 5 seconds of the previous button press. In addition to the factory set code, 3 personal keyless entry keypad codes can be set. For information on programming the personal keyless entry codes, refer to Keyless Entry Keypad Code Programming Testing and Inspection.
Unlocking the Doors with the Keyless Entry Keypad System
To unlock the driver door, enter either the factory set code or the personal code (each digit must be pressed within 5 seconds of the prior digit). The interior lamps will illuminate.
To unlock all doors, enter either the factory set code or the personal code (driver door unlocks) and press the 3/4 button within 5 seconds.
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 buttons at the same time.
Releasing the Luggage Compartment Lid with the Keyless Entry Keypad System
To release the luggage compartment, enter the factory set or the personal code and the driver door will unlock. Press the 5/6 button within 5 seconds.
Anti-Scan Feature
To provide added security, the keyless entry 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.
Anti-scan is turned off after 1 minute of keypad inactivity or if the doors are electronically unlocked using an RKE transmitter or a door lock control switch.
