FORD 2003 Expedition v.4 - Manual (Page 146)

Replacing the battery
The remote transmitter is powered by one coin type three-volt lithium
battery CR2032 or equivalent. Typical operating range will allow you to
be up to 10 meters (33 feet) away from your vehicle. A decrease in
operating range can be caused by the following factors:
• Weather conditions
• Nearby radio towers
• Structures around the vehicle
• Other vehicles parked next to the vehicle
To replace the battery:
1. Twist a thin coin between the two
halves of the transmitter near the
key ring. DO NOT TAKE THE
FRONT PART OF THE
TRANSMITTER APART.
2. Do not wipe off any grease on the
battery terminals on the back
surface of the circuit board.
3. Place the positive (+) side of new
battery in the same orientation.
Refer to the diagram inside the transmitter unit. Press the battery down
to ensure that it is fully seated in the battery housing cavity.
4. Snap the two halves back together.
Replacement of the battery will not cause the remote transmitter to
become deprogrammed from your vehicle. The remote transmitter should
operate normally after battery replacement.
Replacing lost transmitters
If a remote transmitter has been lost and you would like to remove it
from the vehicle’s memory, or you would like to purchase additional
remote transmitters and have them programmed to your vehicle:
• Take all your vehicle’s transmitters to your dealer for programming, or
• Perform the programming procedure yourself.
