Using the remote keyless entry transmitter, you can lock and unlock your doors or release your trunk from about 3 feet (1 m) up to 30 feet (9 m) away.

LOCK: Press the LOCK button to lock all the doors.

UNLOCK:  Press the UNLOCK button once to unlock the driver's door and turn on the interior lamps. See "Illumination on Remote Activation" later in this section for more details. Pause for about one second, then press UNLOCK again to unlock the passenger door.

(Remote Alarm):  Press this button to activate an alarm. The ignition must be in OFF or ACC for the remote alarm to work. When you press the remote button, the headlamps will flash, the horn will sound repeatedly and your interior lamps will turn on attracting attention if you need it. The alarm will continue until one of the following occurs:

    • The remote alarm button is pressed a second time,
    • the vehicle's ignition is turned to ON or
    • an alarm period of 110 seconds has elapsed.
(Trunk Release):  Press the button to release the trunk. Operating the remote keyless entry transmitter may interact with the content theft-deterrent system, if your vehicle has this option. See Content Theft-Deterrent .

Transmitter Verification

This feature provides feedback that a command has been received by the vehicle, if your key fob has been programmed to Mode 3: Full, see FOB HORN (Remote Audible Verification) under Vehicle Personalization for more information. The headlamps and back-up lamps will flash on every lock command and on the first unlock command. The horn will also sound once for every lock and twice for the first unlock command. Silent operation and other options may be selected for this feature.

If your vehicle has the optional content theft-deterrent system, the first time the remote unlock is received and the alarm has been previously activated, three flashes from the headlamps will be seen and three chirps will be heard to indicate an alarm condition has occurred since last arming. See Content Theft-Deterrent .

Illumination on Remote Activation

The interior lamps will come on when either the UNLOCK, the trunk release or the remote alarm button is pressed. The interior lamps will remain on for 40 seconds or until the ignition is turned to ON or LOCK is pressed. Locking the doors with the power door locks will also cause the lamps to turn off. If a door is opened during the 40 second period, the interior lamps will remain on while the door is open.

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 a maximum of four transmitters matched to it.

If you prefer, you can complete this procedure yourself. See Vehicle Personalization for more information.

Battery Replacement

Under normal use, the battery in your remote keyless entry transmitter should last about three 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, do not touch any of the circuitry on the transmitter. Static from your body could damage the transmitter.

To replace the battery do the following:

  1. Insert a flat object like a coin into the slot on the back of the transmitter. Gently pry apart the front and back.
  2. Gently pry the battery out of the transmitter. Do not use a metal object.
  3. Put the new battery into the transmitter as shown on the transmitter. Use type CR2032 battery or equivalent.
  4. Put the two halves back together. Make sure the halves are together tightly so water won't get in.
  5. Resynchronize and then test the transmitter.

Resynchronization

After you have changed the battery in your transmitter, you will need to resynchronize the transmitter. To do this, press the LOCK and UNLOCK buttons on the transmitter at the same time and hold for about seven seconds or until one horn chirp is heard.
