Reassembling the Key Fob
- Clip the internal unit back together: Carefully align and clip the two parts of the internal unit back together.
- Close the key fob casing: Align the two halves of the key fob casing and gently press them together until they snap closed.
- Reinstall the screw: Replace the small Phillips head screw and tighten it securely, but avoid over-tightening.
Testing Your Key Fob
After reassembly, test your key fob to ensure it’s working correctly. Press the lock, unlock, and panic buttons to verify responsiveness. If everything works as expected, you’ve successfully replaced your 2008 Honda Ridgeline key fob battery!
Conclusion
Replacing the battery in your 2008 Honda Ridgeline key fob is a simple DIY task that can save you time and money.
