The 2015 Honda Fit key fob uses a 3-volt CR2032 lithium coin battery. This is the standard size for most Honda remotes from that year, including the common flip-key designs.
Battery type and compatibility
In the 2015 Fit (second generation), Honda generally ships remote key fobs that require a CR2032 coin cell. The battery size remains consistent across most trims and markets, though rare regional variations or aftermarket fobs can differ.
How to identify the correct battery
Look inside the fob for the current battery: a 20 mm diameter coin cell with "CR2032" stamped on the can. If you see a different marking, you may have a non-standard fob. When in doubt, bring the fob to a dealer or battery retailer to confirm.
Replacing the battery
To replace the battery, follow these steps:
- Gather supplies: a replacement CR2032 and a small flat screwdriver or coin for prying.
- Carefully pry apart the two halves of the key fob along the seam, avoiding damage to the rubber gasket.
- Remove the old battery, noting its orientation (positive side usually facing up).
- Insert the new CR2032 with the correct orientation, ensuring it sits flat and makes good contact with the terminals.
- Snap the fob halves back together and test the buttons from a short distance.
After replacing the battery, if the remote still behaves inconsistently, check the battery seating, try a fresh battery, or visit a Honda dealer for diagnostics or reprogramming if necessary.
Additional considerations
Dispose of old batteries responsibly at a recycling facility. If your Fit uses a very early or regional variant remote, it may have a different battery, but CR2032 is the standard for most 2015 Fit fobs.
Summary
The 2015 Honda Fit key fob typically uses a 3V CR2032 lithium coin battery. Replacing it is a straightforward DIY task: pry open the fob, swap in a fresh CR2032 with proper orientation, reassemble, and test. Always verify the battery type if you notice any unusual behavior and consult a dealer if problems persist.
