Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about four 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.
For battery replacement, use a Duracell
R
battery,
type DL - 2032, or a similar type.
To replace the battery:
1. Insert a thin coin into the notch near the key ring.
Turn the coin counterclockwise to separate the two
halves of the transmitter.
2. Once the transmitter is separated, use a pencil eraser
to remove the old battery. Do not use a metal object.
