A 3-volt CR2032 coin-cell battery powers most 2016 Honda key fobs.
Across the 2016 model year, Honda’s remote keys for Civic, Accord, CR-V, Fit and related models share a common design and battery type. However, there can be exceptions based on trim, regional specifications, or aftermarket replacements. This article explains the standard battery, how to verify it, and how to replace it safely.
Common battery type for 2016 Honda key fobs
The standard choice is a 3V lithium coin cell CR2032. Some fobs might use a CR2025, which is thinner, but CR2032 is the typical replacement. To be sure, check the fob itself or the owner's manual for the exact specification.
- Battery type and size: CR2032, 3V lithium coin cell
- Alternatives: CR2025 or other sizes are uncommon and may not fit properly
- How to verify: the battery size is often printed on the battery you remove or listed in the manual
Using the correct battery ensures proper remote range and features like lock/unlock and panic. If your fob is aftermarket or a dealer-specific variation, confirm the battery type with the dealer or manual.
Replacing the battery
Replacing the battery is straightforward and typically takes just a few minutes with a small flat tool. Follow these steps for a typical 2016 Honda key fob:
- Prepare a small flat tool or coin to gently pry the fob apart without damaging the shell.

If you encounter issues or have a nonstandard fob, contact a Honda dealer or automotive locksmith for assistance.
