How to Replace Your 2021 Honda Civic Key Fob Battery
Replacing the battery in your Honda Civic key fob is a quick and easy process that you can do yourself. Here’s a step-by-step guide:
- Locate the Release Button: On the back of your key fob, find the small release button or switch.
- Release the Key: Press the release button and gently slide the metal key out of the fob.
- Open the Fob Casing: Use the tip of the metal key or a small flat-head screwdriver to carefully pry open the key fob casing at the designated seam.
- Remove the Old Battery: Gently remove the old CR2032 battery from its compartment. Note the battery’s orientation for correct replacement.
- Install the New Battery: Insert the new CR2032 battery into the compartment, ensuring it matches the same orientation as the old battery (positive side up).
