The first time you need to change the original battery in your Honda key fob can be tricky—there are tiny parts in the battery in your remote key that you don’t want to lose. Thankfully, we can walk you through the process of how to replace the battery in your Honda key fob, making you a car-key expert!

Replacing Your Honda Key Battery
- With a jeweler’s screwdriver at the ready, remove the tiny screw on your key fob. With the screw removed, you should be able to remove the two plastic halves of the key fob with a flathead screwdriver. Be careful to hold the fob together, so that the contents and external buttons don’t fall loose.
- When you remove the dead battery, take note of the positive and negative sides. Also, try not to touch the battery terminals, as the oils on your skin can cause corrosion which can shorten the life of the battery.
- 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.
- Align the two halves of the key fob and gently apply pressure until you hear it snap together. Then replace the screw.
Choosing the Right Honda Key Fob Battery
If your key fob falls apart, don’t panic! You can always use your backup key fob as a guide to reassemble it.
- Place the buttons into the correct slots.
- Insert the crossbar between the empty spaces of the top two buttons, with the crossbar’s curvature facing outwards.
- Insert the battery back into the motherboard with the positive sign facing out.
- Put the motherboard back into the key fob with the rubber film up against the buttons.
- Line the back of the key fob up with the front and press it back together until you hear it snap back into place.
- Stand next to your vehicle and press all the buttons to make sure that they are working properly.
