The 2015 Honda Fit key fob uses a CR2032 3-volt lithium coin cell.
This is the standard battery size for most 2015 Fit remotes. If your fob seems different or you want to confirm, check the current battery inside or refer to the owner's manual or contact a Honda dealer for guidance.
Battery size and compatibility
The CR2032 is a common choice for compact car remotes due to its small form and reliable 3-volt capacity. It is widely available at auto parts stores, electronics retailers, and online. When replacing, always use a fresh battery to ensure optimal performance and avoid leakage.
How to identify the correct battery
To confirm the exact size, open the fob and inspect the battery. The size is often stamped on the battery itself, or you can compare its dimensions to a standard CR2032 (about 20 mm in diameter and 3.2 mm thick). If you see a different size, use that as the reference when purchasing a replacement.
Replacing the battery
Before replacing, understand the steps so you can do it safely and correctly.
- Use a small flathead screwdriver or a prying tool to gently separate the two halves of the fob along the seam.
- Carefully lift away the back cover to expose the battery without damaging the internal components.
- Remove the old battery, noting the orientation (the plus side usually faces up).
- Insert a new CR2032 battery with the plus (+) side facing up and ensure it sits flat.
- Snap the two halves back together until they click securely.
- Test the fob by pressing the lock/unlock buttons from a short distance to verify operation.
With the battery replaced, the fob should function normally. If it still doesn’t work, the issue may lie with the key fob’s circuitry or buttons rather than the battery itself.
Where to buy and cost
CR2032 batteries are widely available at automotive parts stores, electronics retailers, pharmacies, and online marketplaces. A typical price range is about $2–$6 per battery, depending on brand and retailer. Always opt for fresh stock and avoid expired batteries to maximize lifespan.
Summary
In short, the 2015 Honda Fit key fob uses a CR2032 3V lithium coin cell. Replacing it is a straightforward DIY task: open the fob, swap in a fresh CR2032 with the correct orientation, and reassemble. If problems persist after replacement, seek assistance from a dealer or locksmith to diagnose potential circuitry issues.
