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.

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.

The Driver Information Center (DIC) will display a KEY FOB  # BATTERY LOW message when the transmitter battery is low.

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 in the remote keyless entry transmitter do the following:

  1. Insert a thin coin in the slot between the covers of the transmitter housing. Gently pry the transmitter apart.
  2. Remove and replace the battery with a three-volt CR2032 or equivalent battery.
  3. Align the covers and snap them together.
  4. Check the operation of the transmitter.
