The 2015 Honda Accord key fob uses a CR2032 3-volt lithium coin cell.
Battery type
The remote for many 2015 Accord models is powered by a CR2032 coin cell. This 3V battery is widely available at hardware stores, pharmacies, and online. If you’re unsure, inspect the current battery inside the fob or consult the owner’s manual for the exact specification.
Alternative battery types
In rare cases or regional variants, a different coin cell such as a CR2025 may be used. If the fob battery is not CR2032, check for markings on the old battery and replace accordingly.
Replacement steps
Follow these steps to replace the battery in the standard Honda Accord remote. This guide covers a typical flip-style fob without visible screws.
- Obtain a fresh CR2032 3V battery.
- Use a small flat-head screwdriver or a plastic opening tool to gently pry the two halves of the fob apart along the seam.
- Carefully lift out the old battery, noting which side faced up.
- Insert the new CR2032 with the correct orientation (usually the + side facing up toward you).
- Snap the fob halves back together and test the buttons to ensure the doors, trunk release, and panic functions work.
Disposal tip: recycle the old battery at a battery recycling bin or store it until you can drop it off at an appropriate facility.
If the fob doesn’t respond after replacement, double-check the battery seating, ensure there are no bent contacts, and try again. If it still fails, contact a Honda dealer or locksmith for diagnosis or reprogramming if needed.
Summary
The battery for a 2015 Honda Accord key fob is a CR2032 3V coin cell. Replacement involves opening the fob, swapping in a new CR2032 with proper orientation, and reassembling; most cars do not require any programming after a battery change. If problems persist after replacement, seek professional assistance.
