Identifying the Correct Battery Type for Your 2010 Honda Accord Key Fob
The battery you’ll need for your 2010 Honda Accord key fob is a CR1616 3V lithium coin cell battery. This is a common type of watch battery and readily available at most drugstores, supermarkets, and online retailers. You won’t find this information in your Honda owner’s manual, but you can rely on this guide to provide you with the accurate 2010 Honda Accord key fob battery type.
Step-by-Step Guide to Replacing Your 2010 Honda Accord Key Fob Battery
Replacing the battery is a simple DIY task. Here’s how to do it:
-
Gather Your Tools: You will need a #0 Phillips head screwdriver (jeweler’s size is ideal) and a small flathead screwdriver or similar thin tool to gently pry open the key fob case. For older key fobs, the screw might be tight due to thread-locking chemicals. Applying a little heat to the screwdriver tip (carefully, with a lighter or candle) can help loosen it.
-
Locate and Remove the Screw: Turn your key fob over and find the small Phillips head screw on the back. Use your #0 Phillips head screwdriver to carefully loosen and remove this screw. Keep the screw in a safe place so you don’t lose it.
-
Open the Key Fob Case: Once the screw is removed, you can separate the two halves of the key fob case. Some key fobs have a small slot on the side to help with prying them apart. If your key fob is a bit stubborn, gently apply pressure to separate the halves. Be patient and avoid using excessive force to prevent damaging the plastic case.
-
Access the Battery Capsule: Inside the key fob, you will see a small black capsule containing the circuit board and battery. Carefully remove this capsule from the key fob casing.
-
Open the Battery Capsule and Identify Battery Orientation: Use your small flathead screwdriver to gently pry open the battery capsule. Pay close attention to the orientation of the battery inside the capsule before removing it. Note which side is facing up (+) and which is facing down (-). This is important for correct replacement.
-
Remove the Old Battery and Clean Contacts: Take out the old CR1616 battery. Inspect the battery contacts inside the capsule for any dielectric grease. According to a Honda service manager, weak signals in 2010 Honda Accord key fobs can sometimes be caused by this grease interfering with the battery connection. If you see any grease, gently wipe it away from both the battery contacts and the contact points on the circuit board.
-
Insert the New Battery: Install the new CR1616 3V battery into the capsule, ensuring it is in the correct orientation (positive side up if that was the original orientation).
-
Reassemble the Key Fob: Carefully close the battery capsule, place it back into the key fob casing, and snap the two halves of the key fob case back together. Finally, re-insert and tighten the Phillips head screw.
