Identifying a Dying Key Fob Battery
Several signs indicate your Nissan Sentra key fob battery is nearing its end. Recognizing these early can prevent unexpected lockouts. Reduced range is a common first symptom.

Finally, inconsistent functionality, where the key fob sometimes works and sometimes doesn’t, is another tell-tale sign.
What Battery Does a Nissan Sentra Key Fob Use?
Most Nissan Sentra key fobs use a CR2032 battery. This small, circular battery is readily available at most electronics stores, pharmacies, and online retailers. It’s always a good idea to double-check your owner’s manual to confirm the exact battery type for your specific Sentra model year. Using the correct battery ensures optimal key fob performance.
Tools Needed for Nissan Sentra Key Fob Battery Replacement
Before starting the replacement process, gather the necessary tools. You’ll need a small flat-head screwdriver or a similar tool to pry open the key fob casing. A replacement CR2032 battery is obviously essential. Optionally, a small tray or container can be helpful to hold the small parts and prevent them from getting lost.
