To replace the battery:
1. Insert a small coin or flat
notch near the key ring to separate the bottom half
from the top half of the transmitter.
2. Remove the battery and replace it with the new one.
Make sure the positive (+) side of the battery faces
upward. For battery replacement, use a three
battery, type CR2016, or equivalent.
3. Snap the transmitter back together tightly to be sure
no moisture can enter.
