Replacing The Batteries; Opening The Remote Transmitter - Ford Ranger Owner's Manual

The remote entry system may not arm and disarm non-factory
installed anti-theft systems.

Replacing the batteries

The remote entry transmitter is powered by two coin type
three-volt lithium 2016 batteries (included) that should last for
several years of normal use. If you notice a significant decrease
in operating range, the batteries should be replaced.
Replacement batteries can be purchased at most pharmacies,
watch stores or at your Ford or Lincoln-Mercury dealer.
NOTE: The operating range of the remote entry system can
also be affected by weather conditions (such as very
cold temperatures) or structures around the vehicle
(buildings, other vehicles, radio and TV towers, etc.).
Typical operating range will allow you to be up to 33
feet (10 meters) away from your vehicle.

Opening the remote transmitter

The transmitter can be snapped apart to replace the batteries by
twisting a thin coin between the two halves of the transmitter.
DO NOT TAKE THE FRONT PART OF THE TRANSMITTER
APART. When installing the new batteries, be sure to place the
positive (+) side down as marked. Snap the two halves back
together.
