Battery Replacement
Under normal use, the battery in your keyless
access transmitter should last about three years.
The battery is weak if the transmitter will not
work at the normal range in any location. If you
have to get close to your vehicle before the
transmitter works, it is probably time to change the
battery. The DIC may display KEY FOB
BATTERY LOW.
A weak battery may also cause the DIC to display
NO FOBS DETECTED when you try to start
the vehicle. If this happens, place the transmitter
in the center console storage area transmitter
pocket with the buttons facing to the front of the
vehicle. Then, with the vehicle in PARK (P)
or NEUTRAL (N), press the brake pedal and the
start button. SeeStarting the Engine on page 113,
for additional information about your vehicle’s
electronic keyless ignition with push button start.
Although this will start the vehicle, it is
recommended that you replace the transmitter
battery as soon as possible.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.
