Theft-Deterrent System

The remote keyless entry transmitter will arm the theft-deterrent system whenever the doors are closed and you push the lock button when the ignition is off. It will disarm the system when you push the unlock button.

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.

See your dealer to match additional transmitters to your vehicle.

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 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 thin coin, or similar object, into the notch near the key ring. Turn it 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 as the instructions under the cover indicate. Use a Duracell® battery, type DL-2032, or a similar type.
  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

After replacing the battery in your transmitter, or if only the remote alarm works, the transmitter needs to be resynchronized to the receiver. Do this by pressing and holding both the lock and unlock buttons at the same time for about eight seconds. You must be within range of the vehicle.

Once the transmitter has been resynchronized, the horn will chirp and the exterior lamps will flash once. The system should now operate properly.
