A new CR2025 or CR2032 battery: Most Nissan key fobs use one of these. Check your owner’s manual to confirm the correct type for your model.
A small flat-head screwdriver or a similar tool: This is for prying open the key fob casing. Be careful not to use anything too sharp that could damage the plastic.
Optional: A small flashlight: This can help you see inside the key fob, especially in dimly lit areas.

Steps to Change Your Nissan Key Fob Battery

The exact process may vary slightly depending on your key fob type, but the general steps are as follows:

Locate the release button or notch: This is usually on the side or back of the fob.
Use the flat-head screwdriver to gently pry open the fob casing: Be careful not to damage the plastic. Start by inserting the screwdriver into the notch and gently twisting to separate the two halves of the fob.
Identify the old battery: It’s usually housed in a small compartment.
Carefully remove the old battery: Use the flat-head screwdriver to gently pry it out.
Insert the new battery: Make sure it’s oriented correctly, matching the positive (+) and negative (-) sides with the markings inside the fob.
