The autolock feature can be enabled/disabled, refer to Autolock and Auto-Unlock Programming Autolock and Auto-Unlock Programming 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.

NOTE: The auto-unlock feature comes disabled from the factory on vehicles equipped with a manual transaxle, but can be enabled.

The auto-unlock feature unlocks all the doors when the following conditions are met:

- The ignition is in the ON position
- 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 position
- And the driver door is opened within 10 minutes of the ignition being switched to the LOCK or ACC position

The auto-unlock feature can be enabled/disabled independently of autolock. 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 (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 a Remote Keyless Entry (RKE) command from an Integrated Keyhead Transmitter (IKT) or the keyless entry keypad (if equipped).

Remote Keyless Entry (RKE)

The 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 Antitheft and Alarm Systems. Using Two Programmed Keys Using Diagnostic Equipment For information on programming the conventional keyfobs, refer to Remote Keyless Entry (RKE) Transmitter Programming Transmitter.





The IKT carries out the following functions:

- Unlocks the driver door
- Unlocks all doors
- Locks all doors
- Releases the luggage compartment lid latch
- Arms/disarms the perimeter alarm
- 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 (late vehicles only)
- Recalls the memory seat position associated with a particular remote entry device (when enabled) (MKZ)
- 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 (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 one-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 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 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 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

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 carries out the following functions:

- Unlocks the driver door
- Unlocks all the doors
- Locks all doors
- Enables/disables auto-unlocking
- Enables/disables autolocking
- Arms/disarms the perimeter alarm
- Recalls the memory seat position associated with a particular customer key code (when enabled)
- Releases the luggage compartment lid latch
- Programs/erases the customer key code(s)
- 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 factory set 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. In addition to the factory set code, 3 personal codes can also be programmed. For additional information on programming the personal keypad codes, refer to Keyless Entry Keypad Code Programming Testing and Inspection.

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 (if stepped unlock is disabled), 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. This feature can be changed to 1-step unlock, so that all the doors unlock on receipt of the factory set or personal code. Refer to Stepped Unlock Programming Stepped Unlock Programming for programming information.

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.

The headlamps (Fusion, Milan), fog lamps (MKZ), park lamps, and tail lamps illuminate when the unlock control on the IKT is pressed. The perimeter lighting feature turns off the lamps if:

- The ignition switch is turned to the ON position
- The IKT lock control is pressed
- The vehicle is locked using the keyless entry keypad (if equipped)
- 25 seconds have elapsed since the perimeter lighting was activated
