How to Replace the Key Fob Battery in a Honda Ridgeline

1. Remove the built-in key from the remote.
2. Turn the remote so the buttons face down.
3. Carefully pry the edge of the upper half of the cover off with a coin.
4. Swap in the new battery, making sure the polarity is correct.

• Battery type: CR2032.
• Wrap the coin in a cloth to prevent scratching the keyless remote.
• Replace the battery if the indicator does not come on when the button is pressed.
