• A small flat-edge tool or flathead screwdriver

Steps

1. Place the transmitter face down on a flat surface, with the buttons facing the table.

2. Locate the key-ring corner of the transmitter.

3. Using a small flat-edge tool or screwdriver, gently pry the case open at the key-ring corner.

4. Remove the coin-shaped battery from the holder.

5. Insert the new CR2032 battery, making sure the positive (+) side is facing up.

6. Align the two halves of the transmitter and press them together firmly until the case snaps closed.

Once completed, the transmitter should be ready for use.
