Is your 2009 Honda Accord key fob starting to act up? You might be experiencing weak signals or inconsistent performance, and the most common culprit is a low battery. Fortunately, replacing the battery in your 2009 Accord key fob is a simple task you can easily do yourself at home, saving you time and a trip to the dealership. This guide will walk you through the process step-by-step.
To replace your 2009 Accord Key Fob Battery, you will need a few basic tools:
- A small Phillips head screwdriver (#0 or jeweler’s size)
- A small flathead screwdriver or similar thin tool
- A new CR1616 3V battery
Once you have gathered your tools and new battery, follow these steps to replace your 2009 Accord key fob battery:
- Locate the Screw: Turn your key fob over and find the small Phillips head screw on the back casing.
- Unscrew and Open: Use your Phillips head screwdriver to carefully loosen and remove the screw. Keep the screw in a safe place. Once removed, you can gently pry apart the two halves of the key fob casing. Some models have a small slot to help with prying.
- Access the Battery Capsule: Inside the key fob, you’ll see a small black capsule containing the circuit board and battery. Carefully remove this capsule.
- Open the Capsule: Use your small flathead screwdriver to gently pry open the two halves of the black capsule. Note the orientation of the capsule pieces for reassembly.
- Replace the Battery: Identify the CR1616 battery. Remove the old battery and replace it with the new CR1616 battery, ensuring the positive (+) side is facing the correct direction (usually upwards towards the positive contact).
- Clean if Necessary: Inspect the battery contacts for any grease. Honda has acknowledged a potential issue with dielectric grease interfering with battery contact in these key fobs. If you see grease, gently wipe it away from both the battery and the contact points with a clean, dry cloth.
- Reassemble: Carefully reassemble the black capsule, ensuring the two halves are correctly aligned. Then, place the capsule back into the key fob casing. Snap the two halves of the key fob casing back together and replace the Phillips head screw.
