Is your 2010 Honda key fob starting to act up? You might be experiencing decreased range or inconsistent locking and unlocking. Often, the culprit is simply a dead battery. Replacing the battery in your 2010 Honda key fob is a straightforward task you can easily do yourself, saving you time and money compared to a dealership visit.
The battery you’ll need is a CR1616, a 3V lithium battery. These can sometimes be a little less common than standard watch batteries, but are readily available at most drugstores, online retailers, and some larger grocery stores. You can find brands like Energizer or Duracell. Buying online might offer cost savings, especially if you need to replace batteries in multiple fobs.
Here’s how to replace the battery in your 2010 Honda key fob:
-
Locate the small Phillips head screw on the back of your key fob.
-
Using a mini Phillips head screwdriver, carefully unscrew and remove this screw. It might be a little tight initially. Applying firm, steady pressure while turning is key to avoid stripping the screw head.
-
Once the screw is removed, the key fob casing will split open into two halves.
-
Inside, you’ll see a black plastic inner cassette containing the electronics and the battery. Gently pry this inner cassette open, separating it into two pieces.
-
The CR1616 battery will be visible, nestled in one half of the cassette.
-
Remove the old battery. When inserting the new CR1616 battery, ensure the positive (+) side (usually marked with writing) is facing down, so the writing is not visible once installed. Using a cloth or gloved fingers to handle the battery can prevent transferring oils to the battery contacts.
-
Carefully reassemble the inner cassette, ensuring it snaps back together securely.
-
Close the key fob casing, aligning the two halves.
-
Replace and tighten the Phillips head screw. Be firm but avoid over-tightening.
Tips for a Smooth Replacement:
- If the screw is very tight, use a small amount of penetrating oil or try using a slightly larger handled screwdriver for better grip and leverage. Press down firmly to avoid stripping the screw.
- Work on a soft surface like a terry cloth to protect the key fob from scratches.
- Double-check the battery orientation before reassembling.
Replacing your 2010 Honda Key Fob Battery is a quick and easy DIY task. By following these simple steps, you can restore your key fob’s functionality and avoid unnecessary trips to the dealership.
