Lincoln Aviator: Handles, Locks, Latches and Entry Systems / Description and Operation - Handles, Locks, Latches and Entry Systems - Overview

Overview

NOTE: The Phone As A Key feature can also be used to lock/unlock the vehicle. Refer to section 419-01C for information regarding this feature.

The door latches are controlled electronically by the door latch release switch located in the door handle.

The virtual lock/unlock feature locks or unlocks the doors upon a request from a door lock control switch, the liftgate door lock switch, the keyless entry keypad, the passive entry system, a RKE transmitter or other lock/unlock features controlled by the BCM. The virtual lock/unlock feature replaces the need for mechanical locking components within the door latch

The passive entry feature unlocks/unlatches the door(s) or opens the liftgate without using a bladed key.

A soft-close feature for the doors (if equipped) is part of the latching system. With this feature, minimal effort is required to close a door. When a door latches (a small distance away from the fully closed position), the door cinch motor activates to pull the door fully closed.

If equipped with an electronic fuel filler door release (hybrid vehicles), excessive fuel vapor pressure is removed from the fuel tank before the fuel filler door latch is released.

If equipped with a fuel filler door lock (non-hybrid vehicles), the fuel filler door lock operates in conjunction with the driver door lock/unlock operation.

Electronic Door Unlatch and Door Cinch

The doors are electronically unlatched and if equipped with cinch motors, electronically pull the door closed when the secondary latch (first click) is detected.

The driver door has 2 mechanical ways to unlatch the door in the event of a power failure of the vehicle battery, the passive key or the door latch. A key can be used from the outside of the vehicle (refer to the Owner's Literature for the location of the key cylinder) or from the auxiliary door latch release handle located on the driver front door trim panel.

Door Unlatch

A door can be unlatched when the door latch is in the unlock mode.

When a door latch release switch (located on the inside of the exterior pull handle and a button located in the door trim panel) is activated, a solenoid internal to the door latch activates to release the door latch.

When a door latch fault is detected, a door latch fault message displays in the IPC.

Each door latch has an internal power backup that allows the door latch release to function for approximately 20 activations or approximately 72 hours after a power loss (such as a disconnected or depleted battery).

The door unlatch operation is as follows:


  Press Of Exterior Door Latch Release Switch


Vehicle Speed Lock/Unlock Mode Action To Release Latch
Less than 20 km/h (12.43 mph) Locked Latch does not release
Unlocked Single activation of switch
Greater than 20 km/h (12.43 mph) Locked Latch does not release
Unlocked

  Press Of Interior Door Latch Release Switch

NOTE: The rear doors do not unlatch from the interior release switch when the child safety lock is active.


Vehicle Speed Lock/Unlock Mode Action To Release Latch
Less than 3 km/h (1.86 mph) Locked and perimeter alarm armed Double activation of switch within 3 seconds or press unlock on the door lock control switch and within 3 seconds press release switch (alarm activates)
Locked Single activation of switch for a front door; Double activation of switch for a rear door
Unlocked Single activation of switch
Greater than 3 km/h (1.86 mph) Locked Triple activation of switch within 2 seconds or press unlock on the door lock control switch and within 2 seconds press release switch
Unlocked

Door Cinch (if equipped)

When the door is latched in the secondary latch position (first click), such as when the door is not pulled with enough force to fully latch the door in the primary position (second click), the cinch motor activates and pulls the door fully closed.

When the door is pulled closed with enough force to fully latch the door, the cinch motor does not activate.

The door cinch motors are part of the door latch control modules and cannot be serviced separately.

Electronic Door Locks

The door latches do not use actuators to lock/unlock the doors. Locking and unlocking the doors is handled electronically and no moving parts are involved.

The door lock control switches, keyless entry keypad, passive entry system and RKE transmitter can be used to place the door latches in locked or unlocked mode.

An unlock override feature in the event of a severe crash event is also present. Depending on the severity of the crash event, approximately 10 seconds after the event is detected, a crash unlock mode is activated allowing the doors to unlatch from the inside or outside door latch release switches. The crash unlock mode is exited by cycling the ignition on and off twice.

Rear Door Child Safety Locks (if equipped)

The power child lock feature electronically activates the rear door child safety lock feature. This feature operates in conjunction with the rear power windows lock-out feature. When the lock-out switch is placed in the LOCK position with the ignition on, the rear door child safety lock feature activates.

When the rear door child safety lock feature is active, the rear doors do not open from the interior door latch release switch.

LED Door Lock Indicators

Each door lock control switch has a door lock indicator to indicate the lock or unlock status of that individual door.

The Light Emitting Diodes (LEDs) are on only during lock mode when the ignition is on, or when the battery saver feature has not activated when the ignition is off.

Switch Inhibit Feature

The switch inhibit feature prevents unauthorized access to the vehicle from the door lock control switches or the power liftgate button located on the headlamp switch. This disables the function of all door lock control switches and the power liftgate button 20 seconds after the vehicle is electronically locked. If any of these switches are activated while they are inhibited, a chime sounds and a message is displayed in the message center to indicate the switches are inhibited. They are re-enabled when the vehicle is electronically unlocked.

This feature can be configured on/off through the message center.

Electronic Door Locking Feedback

The exterior lamps and exterior sounder provide visual and audible feedback when unlocking and locking the doors under certain circumstances. Refer to the following table:


NOTE: The mislock feature (if equipped) chimes the exterior sounder twice (no turn signal flash) if the hood, liftgate or any door is ajar when the lock button is pressed on a valid programmed RKE transmitter. This feature can be configured on/off through the message center.

Keyless Entry Keypad

The keyless entry keypad is integrated into the front door window moulding of the front doors.

When a keypad button is touched, the buttons illuminate. The keypad illumination turns off after 5 seconds have elapsed since the last button press. The keypad also illuminates any time the illuminated entry feature is active.

The keyless entry keypad can be used to:

  • unlock the driver door.
  • unlock all the doors.
  • lock all the doors (except when the driver door is open).
  • program/erase up to 5 user codes.

Locking the Doors with the Keyless Entry Keypad

It is not necessary to enter the factory set or personal code prior to locking all doors. To lock all doors, touch the 7/8 and 9/0 buttons at the same time for approximately 0.5 second. The locking function is disabled when the driver door is open.

Unlocking the Doors with the Keyless Entry Keypad

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 illuminated entry feature activates unless disabled.

To unlock all doors, enter the factory set code or a personal code (driver door unlocks if set to 2-stage unlock) and then touch the 3/4 button within 5 seconds. This feature can be changed to a 1-stage unlock so that all of the doors unlock when a valid code is entered.
Refer to: Staged Unlock Programming (501-14 Handles, Locks, Latches and Entry Systems, General Procedures).

Anti-Scan Feature

To provide added security, the keypad is disabled for 1 minute after 36 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 turns off after 1 minute of keypad inactivity, the unlock button is pressed on a RKE transmitter, a passive entry feature is used, or the ignition is turned on.

Factory Keycode Retrieval

The factory keycode for the keyless entry keypad can be retrieved from a label on the BCM, a wallet card in the Owner's Literature, accessing the code in the message center using the steering wheel switches or by using a diagnostic scan tool.

RKE Transmitter Liftgate Power Open/Close

The RKE transmitter provides a liftgate power open/close function. Press the liftgate button twice within 3 seconds for the liftgate to power open/close.

Panic Alarm (if equipped)

The panic alarm feature provides audible and visual alarms which are evident from the exterior of the vehicle. When the panic alarm button is initially pressed, the feature requests the turn signals flash and the horn sounds for up to 3 minutes or until deactivation. The flashing of the outputs occurs simultaneously.

The panic alarm can only be activated when the ignition is off. This feature is disabled at all other times. Deactivation of an active panic alarm is accomplished when:

  • a second press of the RKE transmitter panic button is detected.
  • the ignition status changes from off.
  • a period of 2 minutes and 45 seconds have elapsed since the initial activation.

Remote Start (if equipped)

The factory-installed remote start allows the vehicle to be remotely started from outside the vehicle. There is a 2- way communication between the passive key and the vehicle to provide the remote start status of the vehicle. The passive key contains a green and a red LED to indicate the remote start status.


  Remote Start LED Feedback

The auto-unlock feature unlocks all of the doors when all of the following conditions have been met:

  • All the doors are closed and locked.
  • The ignition was on.
  • The vehicle was shifted out of park and a speed greater than 20 km/h (12.4 mph) was achieved.
  • The vehicle has come to a stop.
  • The ignition transitions to accessory or off and, within 10 minutes, the driver door is opened.

The auto-unlock feature can be enabled/disabled through the message center.

Smart Unlock

The smart unlock feature prevents the doors from electronically locking when a passive key is left inside the vehicle. When the doors are locked and then closed, the interior of the vehicle is scanned for a valid programmed passive key. If a valid programmed passive key is detected inside the vehicle when the doors are locked and closed, the doors are unlocked.

The smart unlock feature also operates to prevent locking a passive key inside the cargo area. When the liftgate is closed, the interior of the vehicle is scanned for a valid programmed passive key. If a valid programmed passive key is detected inside the cargo area when the liftgate is closed, the liftgate power opens.

To override the smart unlock feature, lock the doors using the keyless entry keypad or another programmed passive key.

Passive Entry

NOTE: When the vehicle 12-volt battery is detected to be below a set threshold, the passive entry feature only functions from the driver door.

The passive entry feature unlocks/unlatches the door(s) or opens the liftgate without having to use a mechanical key blade or the RKE transmitter feature.

Doors

With a programmed passive key within 1 m (3.28 ft) outside a door, touch the lock sensor at the bottom of the keypad or activate the exterior door latch release switch. The doors lock or unlock and unlatch depending upon the input.

The driver front door passive entry feature either unlocks the driver door (if 2-stage unlock is enabled) or all four doors (if 2-stage unlock is disabled). The passive entry feature always locks all four doors when the lock sensor is touched for a half second.
