Is your 2010 Honda Accord key fob starting to feel a bit unresponsive? You might be facing the common issue of a low battery. Knowing the correct 2010 Honda Accord Key Fob Battery Size is the first step to solving this problem and getting your remote working like new again. This guide will provide you with the battery size information, easy steps to replace it, and even a heads-up on a potential issue you might encounter.
The battery you’ll need for your 2010 Honda Accord key fob is a CR1616 3V lithium coin cell battery. This is a widely available watch-type battery that you can find at most drugstores, supermarkets, and online retailers. Honda conveniently uses this standard battery, but surprisingly, they don’t always include this information in the owner’s manual.
Replacing the battery yourself is a straightforward process that can save you a trip to the dealership. Here’s how to do it:
-
Locate the Screw: On the back of your key fob, you’ll find a small Phillips head screw.
-
Unscrew and Open: Use a #0 Phillips head screwdriver to carefully loosen and remove this screw. For older key fobs, the screw might be a bit tight due to thread-locking chemicals Honda uses. Applying a little heat to the screwdriver tip (with a lighter or candle – carefully!) can help loosen it.
-
Separate the Key Fob Halves: Once the screw is out, gently pull apart the two halves of the key fob. There’s often a small slot on the side to help you get started. Be patient as it might require a bit of force to pop open, but avoid excessive force to prevent damaging the plastic casing.
-
Access the Battery Capsule: Inside, you’ll see a small black capsule containing the circuit board and battery. Carefully remove this capsule.
-
Open the Capsule: Use a small flat-head jeweler’s screwdriver to gently pry open the capsule. Pay attention to the orientation of the two halves so you can reassemble it correctly later.
-
Identify and Replace the Battery: You will now see the CR1616 battery. Take note of how the old battery is placed (positive and negative sides). Remove the old battery and replace it with a new CR1616 battery, ensuring the correct orientation for the positive (+) side.
-
Clean Battery Contacts (Important!): Here’s a crucial tip: Honda Accords (and Pilots) from this era sometimes have an issue with dielectric grease getting onto the battery contacts. This grease, while intended to protect electrical connections, can sometimes interfere with the battery contact in the key fob, leading to a weak signal. Before reassembling, check for any grease on the battery contact points (both on the battery and the metal pads in the capsule). If you see grease, gently wipe it away with a clean, dry cloth.
-
Reassemble: Carefully reassemble the capsule, ensuring the two halves fit together correctly. Then, place the capsule back into the key fob casing, snap the two halves of the key fob back together, and reinsert and tighten the Phillips head screw.
