Battery type and compatibility
The CR2032 is a common 3V coin cell used in many car remotes, including the 2013 Accord. It’s compact, widely available, and easy to replace. In rare cases, some markets or fob variants may use a different size, so verify if yours looks different when you open the case.
How to replace the key fob battery
