Is your 2010 Honda Accord key fob acting up? A weak signal can be frustrating, but often the fix is simple: replacing the battery. This guide will walk you through replacing the battery in your 2010 Honda Accord key fob quickly and easily. You might be surprised to find out it’s a straightforward DIY task that can save you a trip to the dealership.
What You’ll Need
Before you begin, gather these simple tools:
- #0 Phillips Head Screwdriver: A standard #0 Phillips screwdriver should work. For older key fobs or if you encounter a tight screw, consider using a higher quality screwdriver and gently warming the tip with a lighter or candle to help loosen any thread-locking chemical Honda may have used.
- Small Jeweler’s Flathead Screwdriver: This will help to gently pry open the key fob casing and the internal capsule.
- CR1616 3V Battery: This is the specific battery type required for a 2010 Honda Accord key fob. You can find these at most drugstores, electronic stores, or online.

Step-by-Step Battery Replacement
Follow these steps to replace your 2010 Honda Accord key fob battery:
- Locate and Loosen the Screw: On the back of your key fob, you’ll find a small Phillips head screw. Use your #0 Phillips screwdriver to carefully loosen and remove this screw. Be patient, as it might be a little tight.
- Separate the Key Fob Halves: Once the screw is removed, gently pull apart the two halves of the key fob. There might be a small slot on the side to help you get started. If it’s a bit stubborn, like many 2010 Honda Accord keys can be, apply firm but careful pressure to separate them.
- Access the Internal Capsule: Inside, you’ll see a small black capsule containing the electronic components and battery. Carefully remove this capsule from the key fob casing.
- Open the Capsule: Using your small flathead screwdriver, gently pry open the capsule. Note the orientation of the two halves of the capsule as they are designed to fit back together in only one direction, ensuring proper battery contact.
- Identify and Replace the Battery: You’ll see the CR1616 battery inside. Take note of its orientation before removing the old battery. Place the new CR1616 battery in the same orientation.
- Clean Contacts (Optional but Recommended): Sometimes, a weak signal isn’t due to a dead battery but rather a buildup of dielectric grease on the battery contacts. If you notice any grease, gently wipe the contact surfaces on both the battery and the capsule with a clean, dry cloth.
- Reassemble: Carefully snap the capsule back together, ensuring the correct orientation. Place the capsule back into the key fob casing, align the two halves of the key fob, and reinsert and tighten the Phillips head screw.
Common Issue: Dielectric Grease
It’s worth noting that Honda Accords from this era, including the 2010 model, are known to sometimes have issues with dielectric grease interfering with the battery contact. If you’re experiencing weak signal issues even after a battery replacement, this grease could be the culprit. Cleaning the contacts as mentioned above can often resolve this problem. Some Honda dealers may even address this issue for free.
By following these simple steps, you can easily replace the battery in your 2010 Honda Accord key fob and ensure reliable performance.
