See "Theft-Deterrent System" following for information on disarming the theft-deterrent system. Press the button again within 5 seconds to unlock the rest of the doors. Your vehicle can be programmed so that the parking lamps or DRL will flash and/or the horn will sound when you unlock the doors with the remote keyless entry transmitter. See your retailer for more information on programming this feature.

Theft-Deterrent System

The remote keyless entry transmitter is used to arm/disarm the theft-deterrent system. Your vehicle's theft-deterrent system can be programmed to three different modes.

Active Arming: The system will arm when the lock button on the remote keyless entry transmitter is pressed. The system will disarm when the unlock button is pressed.

Passive Arming: The system will arm itself one minute after the ignition is turned off and the driver's door has been opened and closed. If the lock button on the transmitter is pressed before the minute has passed, the system will arm immediately. The system will disarm when the unlock button is pressed.

Security System Disable: The system will not arm.

To change the mode that your vehicle is programmed to, do the following:

  1. Turn the ignition to RUN or ACC.
  2. Press the panic alarm button on the transmitter slowly four times within five seconds.
  3. You must complete one of the following within three seconds to change the mode.
  4. • To select the active arming mode, press the lock button on the transmitter.
    • To select the passive arming mode, press the lock button on the transmitter twice within 3 seconds.
    • To select the security system disable mode, press the unlock button on the transmitter.

A chime will sound once the mode has been selected.

If you accidentally set off the alarm when entering/exiting the vehicle, you can shut it off by pressing any button on the remote keyless entry transmitter other than the panic alarm button.

If you hear three horn chirps when you press the unlock button on the transmitter, that means the vehicle's alarm was triggered while you were away.

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 retailer. Remember to bring any remaining transmitters with you when you go to your retailer. When the retailer matches the replacement transmitter to your vehicle, any remaining transmitters must also be matched. Once your retailer 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.

Battery Replacement

Under normal use, the battery in your remote keyless entry transmitter should last about four years.

You can tell the battery is weak if the transmitter will not work at the normal range in any location. If you have to get close to your vehicle before the transmitter works, it is 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.

  1. Use a flat thin object to pry open the transmitter.

  2. Object Number: 1261914  Size: B3
  3. Once the transmitter is separated, use a pencil or similar object to remove the old battery. Do not use a metal object.
  4. Insert the new battery as the instructions under the cover indicate.
  5. Snap the transmitter back together tightly to be sure no moisture can enter.
  6. Check the operation of the transmitter.

If the transmitter does not work, try synchronizing your transmitter with your receiver. See "Resynchronization" for more information.

Resynchronization

This is used to keep the transmitter of the vehicle communicating with the receiver of the vehicle. Resynchronization may be required due to the security method used by this system.

Your vehicle has an automatic resynchronization function built into the system. If your transmitter is not working properly and you have to manually resynchronize, press the lock and unlock buttons at the same time for seven seconds while you are near your vehicle. The doors will lock or unlock, depending on their starting position. If they do not, contact your retailer for service.
