Handles, Locks, Latches and Entry Systems

NOTE: The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).

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.

Hood Latch

The hood latch consists of the following components:

Doors

The door consists of the following components:

Luggage Compartment Lid

The luggage compartment consists of the following components:

Power Lock/Unlock

The power lock/unlock feature requests both of the vehicle doors locked or unlocked upon customer request from either interior door lock switch in the vehicle. The power door locking system functions independently of ignition status or vehicle speed.

Central Locking/Unlocking (If Equipped)

The central locking/unlocking feature allows both doors to be locked or unlocked from a key in the driver door lock cylinder. To unlock the driver door with stepped unlock enabled, turn the key clockwise. To unlock both doors with stepped unlock enabled, turn the key clockwise a second time to unlock all the doors. To unlock both doors with stepped unlock disabled, turn the key clockwise one time. Refer to Stepped Unlock Programming in this section for programming information.

To lock both doors, turn the key counterclockwise.

Autolock

The autolock feature locks all the doors when the following conditions are met:

The autolock feature repeats when:

The autolock feature can be enabled/disabled, refer to Autolock and Auto-Unlock Programming in this section for programming information.

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 following conditions are met:

The auto-unlock feature can be enabled/disabled independently of autolock. Refer to Autolock and Auto-Unlock Programming in this section for programming information.

Smart Unlock

NOTE: It is possible to lock the vehicle with the key in the ignition lock cylinder if the doors are locked with the Remote Keyless Entry (RKE) transmitter, manually locked with the manual push buttons or with another key in the door lock cylinder.

The smart unlock feature prevents the driver door 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 the driver door open, the SJB commands both doors to unlock.

Luggage Compartment Lid Release Switch Inhibit (Convertible Only)

The power door trim switch inhibit feature disables the luggage compartment lid release switch to prevent unauthorized entry into the luggage compartment. This feature allows the convertible top to be left down, and prevent access into the luggage compartment.

The luggage compartment lid release switch is disabled when the following conditions are met:

The luggage compartment lid release switch is enabled when:

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 key programming. During PATS key programming, the Instrument Panel Cluster (IPC) 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. For information on programming the IKTs , refer to Key Programming Using Two Programmed Keys or Integrated Keyhead Transmitter (IKT) Key Programming Using Diagnostic Equipment in Section 419-01B . For information on programming the conventional keyfobs, refer to Remote Keyless Entry (RKE) Transmitter Programming in this section.

The RKE transmitter initiates the following electronic system functions:

The RKE transmitter has a normal operating range of 10 m (33 ft).

Remote Keyless Entry (RKE) Transmitter 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 and provide a long flash of the turn signals (late build vehicles only). If another unlock request is received within 3 seconds of the first, the RKE feature requests the SJB to unlock both doors. This feature can be configured to one-step unlock, so that both doors unlock on the first press of the unlock button. Refer to Stepped Unlock Programming in this section for programming information.

Remote Keyless Entry (RKE) Transmitter Lock/Unlock Control — Lock

The RKE transmitter feature requests that both doors be locked when the lock button on the RKE transmitter is pressed. On any press of the LOCK button with both doors closed, the RKE transmitter feature commands 1 flash of the turn signal lamps. If any door (luggage compartment lid or hood, if equipped with perimeter alarm) is ajar, no flash occurs, indicating that both the doors were locked, but one or more closures are ajar. As soon as the last closure is closed, the turn signal lamps flash once. If 2 presses of the LOCK button are received within 3 seconds, the horn chirps once and the turn signal lamps flash twice to indicate that all the closures are closed and commanded to lock. If any door (luggage compartment lid or hood, if equipped with perimeter alarm) is ajar when the second lock command is received within 3 seconds of the first, the RKE transmitter feature commands the horn chirp twice without flashing the turn signal lamps to indicate that both doors were commanded to lock, but 1 or more closures are ajar. When the key is in the RUN or START position, no turn signal lamp flashes or horn chirp confirmations occur.

Remote Keyless Entry (RKE) Transmitter Luggage Compartment Lid Release

The RKE transmitter feature releases the luggage compartment lid when the luggage compartment lid release button is pressed twice on the RKE transmitter. The luggage compartment lid release button must be pressed twice within 3 seconds for the luggage compartment lid to release. The feature will operate in any ignition key position, but does become disabled after the vehicle reaches a speed of 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 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 a RKE transmitter 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:
