Is your 2009 Honda key fob starting to feel unresponsive? You might be facing the common issue of a dying key fob battery. Don’t worry, replacing it is a straightforward process you can easily do yourself. This guide will walk you through each step, ensuring you get your key fob working like new again.
Tools You’ll Need
Before you begin, gather these simple tools:
- #0 Phillips Screwdriver: Crucial for opening the key fob. For older fobs, heating the screwdriver tip slightly (with a lighter or candle) can help loosen the screw which may have thread locking chemical applied.
- Small Flathead Screwdriver or Jeweler’s Screwdriver: Useful for prying open the key fob casing and the battery capsule.
- CR1616 3V Battery: This is the standard battery for most 2009 Honda key fobs.
Step-by-Step Battery Replacement
Follow these steps to replace your 2009 Honda Key Fob Battery:
Step 1: Loosen the Screw
Locate the small Phillips head screw on the back of your key fob. Use your #0 Phillips screwdriver to carefully loosen and remove this screw. Be patient, as Honda uses a thread locking chemical, especially in older keys. If you encounter resistance, gently heating the tip of your screwdriver can help soften the thread locker.
Step 2: Open the Key Fob Casing
Once the screw is removed, you can separate the two halves of the key fob casing. Many Honda key fobs have a small slot on the side to aid in opening. Insert a small flathead screwdriver or your fingernail into this slot and gently pry the two halves apart. You might feel some resistance, but apply steady pressure until the casing pops open.
Step 3: Access the Battery Capsule
Inside the key fob, you’ll find a small black capsule containing the circuit board and battery. Carefully remove this capsule from the key fob casing. Next, you’ll need to open this capsule. Use a small flathead screwdriver to gently pry open the capsule from one end. Pay attention to the orientation of the two halves of the capsule as they only fit back together correctly in one direction, ensuring proper contact with the battery.
Step 4: Identify and Replace the Battery
With the capsule open, you’ll see the battery. For 2009 Honda models like the Accord and Pilot, the battery is typically a CR1616 3V. Note the orientation of the battery before removing it. Take out the old battery and replace it with the new CR1616 battery, ensuring the correct polarity (+ and -).
It’s worth noting that some 2009 and newer Honda models, like Accords and Pilots, can experience an issue where a protective grease gets onto the battery contacts. If you’re still having issues after replacing the battery, even with a new one, check for grease on both the battery and the contact points inside the capsule. If you see grease, gently wipe it away with a clean, dry cloth before reassembling.
Conclusion
Replacing the battery in your 2009 Honda key fob is a simple DIY task that can save you time and money compared to going to a dealership. By following these steps, you can quickly restore the functionality of your key fob and get back on the road with confidence. Remember to check for that grease issue if problems persist even after a battery change!
