How to Change Your Honda Key Fob Battery

Trying to figure out how to change your Honda key battery? Don’t panic! It’s really very simple and should only take you only a few minutes. The experts in the Parts Department at Honda of Toms River have prepared this step-by-step guide to walk you through Honda key battery replacement. If you find that you need assistance replacing the Honda key fob battery, visit Honda of Toms River, and we will be more than happy to help.

Choosing the Right Honda Key Fob Battery

Most Honda key fobs use a flat circular 3-volt battery, which can usually be found at any hardware store in the Manahawkin and Berkeley area. You can also stop by the Honda of Toms River Parts Department, and we’ll make sure that you get the right battery for your Honda key.

Honda Key Battery Replacement

  1. Press and slide the button that releases the metal key, then slide the key out.
  2. Use the key or a small flathead screwdriver to pry the key fob open.
  3. Press your thumb down right above the battery to hold the fob together so the contents and external buttons don’t fall out.
  4. Remove the dead battery, taking note of the positive and negative sides, in order to install the new battery correctly. Don’t touch the terminals on the new battery. The oils on your skin can cause corrosion, which shortens battery life.
  5. Insert the new battery in the same position as the old one. Use the positive (+) and negative (-) marks inside the key fob as a guide.
  6. Align the two halves of the key fob and gently apply pressure until they snap back together.

Note: If your Honda key fob has a screw that holds the two halves together instead of a button, use a small flathead screwdriver to remove the screw, and then follow the steps above to replace the battery.

What Should I Do If my Honda Key Fob Falls Apart?

If the internal pieces of your key fob fall out, use your spare key as a guide to reassemble it.

  1. Place the buttons into the correct slots.
  2. Insert the crossbar between the empty spaces of the top two buttons, with the crossbar’s curvature facing outwards.
  3. Insert the battery back into the motherboard with the positive sign facing out.
  4. Put the motherboard back into the key fob with the rubber film up against the buttons.
  5. Line up the back of the key fob with the front, and press them together until you hear them snap into place.
  6. Stand next to your vehicle and press all the buttons to make sure that they are working properly.

If you have any problems reassembling your Honda key fob, pay a visit to our Service Center and have our certified technicians assist you.
