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 in the keyless entry transmitter,
do the following:
1. Insert a dime or similar object in the slot between the
covers of the transmitter housing near the key ring
hole. Remove the bottom by twisting the dime.
2. Remove and replace the battery with a three
-
volt
CR2032 or equivalent battery, positive (+) side up.
3. Align the covers and snap them together.
4. Check the operation of the transmitter.
