Car key remote fobs are nice to have, but they all stop working eventually. Even if it’s just a dead battery, you can pretty much guarantee that your car doors will fail to unlock with the remote at one time or another. So, we will explain Replacing the Battery in Honda Key Fob Remote in our article.

While there are a few reasons that a keyless entry remote might stop working, most of them are pretty easy to check yourself. The most common problem with these car key fobs is that the batteries go dead over time, in which case replacing the battery should fix the problem.

Replacing the Battery in Honda Key Fob Remote

When your Honda keyless remote battery is low, use the following steps to open the Honda key fob, remove/replace the battery, and finally, put the key fob back together. It’s everything you need to know when your Honda keyless remote battery is low:

  1. Press and slide the button that releases the metal key, and 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 on how 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.
