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, 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.
3. Align the covers and snap them together.
4. Check the operation of the transmitter.
