For battery replacement, use a Duracell
R
battery, type
DL - 2032, or a similar type.
To replace the battery, do the following:
1. Insert a thin coin, or similar object, into the notch
near the key ring. Turn it 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.
3. Remove and replace the battery as the instructions
under the cover indicate.
4. Snap the transmitter back together tightly to be sure
no moisture can enter.
5. Test the operation of the transmitter with your
vehicle. If the transmitter does not work,
resynchronize the transmitter.
