Steps for Replacing Your Honda Key Battery
Follow the steps below to open a Honda key fob, replace the battery and reassemble it:
- Release the metal key by pressing the designated button and then slide it out.
- Use this key or a small flathead screwdriver to pry open the key fob.
- To prevent the fob and its external buttons from falling apart, press your thumb above the battery to hold it together.
- Take note of the positive and negative sides before removing the old battery to ensure you correctly install the new one. Avoid touching the terminals on the new battery. The natural oils on your skin could lead to corrosion, affecting the battery life.
- Follow the positive (+) and negative (-) signs inside the key fob and place your new battery in the correct position.
- To reassemble the key fob, align the two halves and apply gentle pressure until they snap together.
Note: If your Honda key fob has a small screw securing the halves together, use a small screwdriver to remove it, then proceed with the above-mentioned steps to replace the battery.
What to Do If Your Honda Key Fob Disassembles?
If the internal components of your key fob come apart, use the spare key as a reference to reassemble:
- Align the buttons into their appropriate slots.
- Place the crossbar between the top two buttons' empty spaces with its curving side directed outwards.
- Ensure the positive sign faces outwards when you return the battery to the motherboard.
- Position the motherboard back into the key fob, keeping the rubber film against the buttons.
- Align the back and front of the key fob and exert some pressure until they click into place.
- Test all the buttons near your vehicle to verify they are working correctly.
