Keyless Entry: Description and Operation
GENERAL INFORMATION
NOTE:
In this manual, F.A.S.T.-key (Free-hand Advanced Security Transmitter) is described as Keyless Operation System (KOS).
The keyless operation system (KOS) enables the driver to unlock all the doors and the trunk lid [LANCER], the liftgate [LANCER SPORTBACK] by just pulling the front door outside handle or operating the trunk lid opener switch [LANCER], the liftgate open switch [LANCER SPORTBACK], without taking the key out from his/her pocket or bag when he/she is carrying a keyless operation key that is registered to the vehicle's KOS-ECU. (When the driver's front door outside handle is operated, only the driver's door is unlocked.) KOS also allows the driver to lock all the doors by pressing the lock/unlock switch on the front door outside handle (door entry function), and start the engine without using the conventional mechanical key (engine start function). Moreover, KOS incorporates the keyless entry function with which, like the conventional keyless entry system, a driver can perform the remote operation
(opening/closing of all doors, opening of trunk lid [LANCER] or liftgate [LANCER SPORTBACK], and operation of warning function that warns a person who intends to damage the vehicle *) by operating the lock/unlock /trunk lid [LANCER] button and panic button on the keyless operation key. The system also incorporates the immobilizer function that prohibits the starting of engine by using an unauthorized key as well as the tire pressure monitoring system (TPMS) that issues a warning to a driver by illuminating or flashing the warning light if an abnormality to the tire pressure or system is detected. KOS has the following features:
- Each vehicle is provided with two keyless operation keys, and up to four keyless operation keys can be equipped.
- The keyless operation key also incorporates an indicator light that enables the driver to check if the signal is transmitted correctly or if the battery in the key is discharged.
- The keyless operation key incorporates an emergency key to lock/unlock the front doors when the battery in the keyless operation key is discharged or the keyless operation system is not working normally. Also by using it simultaneously with the keyless operation key
(insert the emergency key into the keyless operation key in the inverted direction), the engine can be started.
NOTE:
If the immobilizer related system failure occurs, the engine may not start.
- The driver can customize KOS;
enabling the door entry/engine start function, disabling the door entry/engine start function, enabling the door locking/unlocking function only, or enabling the engine starting function only.
- The driver can customize KOS;
enabling the door entry/engine start function, disabling the door entry/engine start function, enabling the door locking/unlocking function only, or enabling the engine starting function only.
NOTE:
*: Horn sounds and the headlight flashes.

Main components and functions
NOTE:
*1: When registering the keyless operation keys, KOS-ECU numbers each key (1 to 4) in the order they are registered (initial priority). This priority is renewed each time the doors are locked/unlocked and the IG knob is pressed. For example, when only keys 1 and 3 have responded to the signal sent from KOS-ECU, the new priority of the keys would be 1-3-2-4. When keys 3 and 4 have responded, then the priority of the keys becomes 3-4-1-2.
NOTE:
*2: Illuminates for tire pressure warning. Flashes for about 1 minute and then continuously illuminated for TPMS malfunction warning.

DOOR ENTRY FUNCTION
Due to the abolishment of the unlock sensor for the door outside handle (driver's/passenger's side), the lock switch has been changed to a lock and unlock switch. The unlock/lock control has been changed. The other service procedures are the same as before.
UNLOCKING OPERATION OF DOOR ENTRY FUNCTION
The keyless operation key and KOS-ECU communicate to certify the keyless operation key when the lock/unlock switch on the driver-side/front passenger-side door outside handle or the liftgate lock release handle [LANCER SPORTBACK]
is turned ON.
When KOS-ECU certifies the registered keyless operation key on the outer side of the vehicle, it requests ETACS-ECU to unlock the doors and the liftgate [LANCER SPORTBACK].
CONTROL OF UNLOCKING OPERATION
UNLOCKING OPERATION INHIBITION TIME (WHEN THE LIFTGATE IS OPERATED) [LANCER SPORTBACK]
Considering that the customer operates the lock switch of liftgate lock release handle to make sure the doors are locked, the unlocking operation is prohibited for 3 seconds after the locking operation is performed by the lock switch of liftgate lock release handle.
LOCKING OPERATION OF DOOR ENTRY FUNCTION
The keyless operation key and KOS-ECU communicate to certify the keyless operation key when the lock/unlock switch on the driver-side/front passenger-side door outside handle or the liftgate lock release handle (lock switch) [LANCER SPORTBACK]
is turned ON. When KOS-ECU certifies the registered keyless operation key only on the outer side of the vehicle, it requests ETACS-ECU to lock all the doors and the liftgate [LANCER SPORTBACK].
Dead lock function locks all the doors and liftgate [LANCER SPORTBACK], when the lock/unlock switch of door outside handle (driver's/passenger's side) is pressed once.
NOTE:
When a keyless operation key is located inside the vehicle, KOS-ECU does not output a request for locking all the doors.

KEYLESS OPERATION KEY
The button operation of the keyless operation key allows the system to operate as follows:
POWER DOOR LOCKS WITH SELECTIVE UNLOCKING
The power door lock with selective unlocking works by pressing the lock/unlock switch of door outside handle (driver's side). The other service procedures are the same as before.
- When the lock/unlock switch of door outside handle (driver's side) is pressed once, only the driver's door is unlocked. When the lock/unlock switch of door outside handle (driver's side) is pressed once again within 2 seconds after the driver's door is unlocked, the front passenger's door, rear doors, and the liftgate [LANCER SPORTBACK]
are unlocked.
NOTE:
When the lock/unlock switch of door outside handle (driver's side) is pressed once, only the driver's door is unlocked. When the lock/unlock switch of door outside handle (driver's side) is pressed once again more than 2 seconds after the driver's door is unlocked, the driver's door only is unlocked.
- Using a customization function, the power door locks with selective unlocking can be enabled or disabled (Refer to Configuration Function).
