Open the key fob: Gently insert the flat-head screwdriver or pry tool into the slot and pry open the key fob. Be careful not to damage the casing.
Remove the old battery: Carefully remove the old battery from its compartment. Note the orientation of the positive (+) and negative (-) sides.
Insert the new battery: Place the new CR2032 battery into the compartment, making sure the positive (+) side faces up, just like the old battery.

Syncing Your Key Fob (If Necessary)

Some Nissan models may require you to re-sync your key fob to the car after a battery change. If your key fob doesn’t work after replacing the battery, refer to your owner’s manual for specific syncing instructions for your model.
