Battery size confirmation for your fob
In most 2013 Accord key fobs, the replacement battery is a CR2032. Some regional or dealer-specific fobs may vary, so it’s wise to confirm by opening the fob and inspecting the current battery or by consulting the manual for your exact SKU.
How to replace the key fob battery
To replace the battery, follow these steps. This information helps you perform a safe, quick swap without damaging the fob.
- Purchase a CR2032 3V coin cell from a reputable retailer.
- Use a small flathead screwdriver or a coin to pry apart the two halves of the key fob along the seam.
- Carefully lift off the back cover and remove the old battery, noting the orientation (plus side up).
- Insert the new CR2032 with the plus (+) side facing up and ensure it sits flat and contacts are clean.
- Reassemble the fob by snapping the halves back together and pressing firmly around the edges to seal.
- Test the fob by pressing the buttons to confirm the doors unlock, lock, or the trunk functions as expected.
If the fob still doesn’t respond after replacement, double-check that the battery is oriented correctly, the contacts are clean, and the fob case is fully closed. If problems persist, the issue may be with the circuitry or a need for reprogramming at a dealership or automotive locksmith.
