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. Place the positive (+) side of new
battery UP. Refer to the diagram
inside the transmitter unit.
3. 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
Take all your vehicle’s transmitters
to your dealer if service is required.
If you purchase additional
transmitters (up to four may be
programmed into memory), perform
the following procedure:
To reprogram the transmitters
yourself, place the key in the
ignition and turn from 2 (LOCK) to
3 (OFF) and cycle between 3 (OFF)
and 4(ON) eight times in rapid succession (within 10 seconds) ending in
the ON position. After doors lock/unlock, press any control on all
transmitters (up to four). With each control press of the transmitters,
the door should cycle (lock/unlock) to confirm programming. When
completed, turn the ignition to OFF. The door locks should cycle
(lock/unlock) one last time to confirm completion of programming.
All transmitters must be programmed at the same time.
