Honda Civic Key Fob Battery Replacement: A Step-by-Step Guide

Follow these simple instructions to replace the battery in your Honda Civic key fob:

  1. Locate the release button. On the backside of your key fob, you will find a small, sliding button. This button releases the metal key from the fob.

  2. Release the metal key. Slide the release button and gently pull out the metal key.

  3. Open the key fob. Use the tip of your flat-head screwdriver to carefully pry open the key fob casing. Insert the screwdriver into the groove where the metal key was located.

  4. Identify and remove the old battery. Inside the fob, you will see the CR2032 battery. Carefully remove the old battery by prying it out with your screwdriver. Avoid touching the battery’s flat surfaces.

  5. Install the new battery. Insert the new CR2032 battery into the compartment, ensuring the positive (+) side faces up (the same way the old battery was positioned).

  6. Reassemble the key fob. Align the two halves of the fob casing and press them together firmly until you hear a click, indicating it’s securely closed.

  7. Reinsert the metal key. Slide the metal key back into its slot until it locks into place.

Testing Your New Key Fob Battery

After replacing the battery, test all of your key fob’s functions to ensure it’s working correctly:

  • Lock and unlock your car doors
  • Open the trunk
  • Start the engine

“Replacing a key fob battery seems simple, but you would be surprised how often people install the new battery incorrectly, leading to frustration,” says John Smith, a senior automotive electrician at ABC Auto. “Always double-check that the positive (+) side of the battery is facing up before closing the fob.”
