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
RFA # BATTERY LOW message when the transmitter
battery is low.
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 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,
positive (+) side down.
3. Align the covers and snap them together.
4. Check the operation of the transmitter.
