REMOTE LOCKING AND UNLOCKING
The hand–held transmitter locks and unlocks the vehicle
doors by sending radio waves to the control module/re-
ceiver in the vehicle. The effective range of the transmitter
varies between 5 and 10 meters (approximately 16 to 32
feet), depending on whether or not objects such as other
vehicles are blocking the path of the radio waves.
The transmitter has a LOCK button and an UNLOCK but-
ton which only function when the ignition is OFF. Pressing
the UNLOCK button has the following effects:
S
The doors are unlocked.
S
The turn signal lamps flash twice.
S
The control module is disarmed.
Pressing the LOCK button has the following effects:
S
The doors are locked.
S
The turn signal lamps flash once.
S
The control module is armed.
The transmitter has a replaceable battery. The battery is
designed to last at least three years before replacement
is necessary.
SECURITY INDICATOR
There is a security indicator on the instrument panel. After
the LOCK button of the transmitter is pressed, the module
is placed in the armed mode, and the security indicator
flashes. The security indicator turns ON for 0.1 second
and OFF for 0.7 second. It then flashes at that frequency
until the control module/receiver is disarmed. If the vehicle
is equipped with an immobilizer, the security indicator is
connected to the immobilizer system instead of the key-
less entry/anti–– theft system.
INTRUSION SENSING
The anti–theft function is armed if the transmitter sends
the LOCK message to the control module/receiver when
the ignition is OFF.
When the hood, the door, or the rear deck lid is opened,
the hood open switch, the door open switch, or the trunk
open switch will change its input to ground. The alarm will
be activated if the hood open sensor, the door open sen-
sor, or the trunk open sensor changes its input to ground
before either of the following conditions occurs:
S
An UNLOCK message is received from the trans-
mitter.
S
The front door tamper switch or the rear deck lid
tamper switch indicates key operation by changing
its input to ground.
The alarm also will be activated if the ignition input is
changed to battery voltage before either of the following
conditions occurs:
S
An UNLOCK message is received from the trans-
mitter.
S
The front door tamper switch or the rear deck lid
tamper switch indicates key operation by changing
its input to ground.
SIREN
The remote keyless entry system is armed when the
LOCK message is received from the transmitter when the
ignition is OFF. When the system is armed, it will activate
the siren and flash the turn signals for 28 seconds if any
of the following conditions occurs:
S
A door is opened without using the key (front door
open switch input is changed to ground).
