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

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.To replace the battery, do the following:
1. Insert a thin object like a dime to separate the
bottom of the transmitter from the top.
2. Remove the battery and replace it with a new one,
making sure the positive (+) side of the battery is
facing down. Use one Panasonic
žthree-volt,
type CR2032, or equivalent battery.
3. Snap the top and bottom together.
