Door Locks
CAUTION:
Unlocked doors can be dangerous.
Passengers -- especially children -- can easily
open the doors and fall out. When a door is
locked, the inside handle won't open it.
Outsiders can easily enter through an unlocked
door when you slow down or stop your vehicle.
This may not be so obvious: You increase the
chance of being thrown out of the vehicle in a
crash if the doors aren't locked. Wear safety belts
properly, lock your doors, and you will be far
better off whenever you drive your vehicle.
There are several ways to lock and unlock your vehicle.
From the outside, use your door key or remote keyless
entry transmitter. With your door key, turning the key
toward the front of the vehicle will lock the door.
Turning the key toward the rear of the vehicle will
unlock it.If your vehicle has a content theft
-deterrent system,
unlock the doors only with the key or remote keyless
entry system. This will avoid setting off the alarm.
To unlock the door from the inside, move the manual
door lock control located above the door handle
rearward. To lock the door, move the manual door lock
control forward.

If your vehicle has this feature, you can lock and unlock
your doors or unlock your trunk from about 3 feet (1 m)
up to 30 feet (9 m) away using the remote keyless entry
lock control transmitter supplied with your vehicle.

Matching Transmitter(s) To Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to bring any
remaining transmitters with you when you go to your
dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have only four transmitters
matched to it.
See your dealer to match transmitters to another vehicle.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's probably time to change the battery.
NOTICE:
When replacing the battery, use care not to touch
any of the circuitry. Static from your body
transferred to these surfaces may damage
the transmitter.

yellowblue
2-13
For battery replacement, use one Duracell
battery, type
DL
-2032, or a similar type.
To replace the battery:
1. Insert a coin into the notch near the key ring. Turn
the coin counterclockwise to separate the two halves
of the transmitter.
2. Once the transmitter is separated, use a pencil eraser
to remove the old battery. Do not use a metal object.3. Remove and replace the battery. Replace it as the
instructions inside the cover indicate.
4. Snap the transmitter back together tightly to be sure
no moisture can enter.
5. Test the operation of the transmitter with your
vehicle. If the transmitter does not work,
resynchronize the transmitter.
Resynchronization
Pressing the transmitter buttons numerous times
(approximately 250 times) out of the vehicle's operating
range may cause the transmitter not to work. Replacing
the battery and pressing the transmitter buttons out of
range will also cause the transmitter not to work. If only
the instant alarm works, the transmitter needs to be
resynchronized to the receiver. Resynchronize by
pressing and holding both the buttons with the lock and
unlock symbols at the same time for about eight
seconds. You must be within range of the vehicle.
Once the transmitter has been resynchronized, the locks
will cycle (the horn may chirp and the exterior lamps
may flash) depending on the security feedback settings.
The system should now operate properly.
