Identifying Your Key Fob Type
The first step is to identify the specific type of Nissan key fob you have. There are a few different designs, and the battery replacement process may vary slightly depending on the model.
- Standard Key Fob: This type typically features a single button for unlocking and locking the car, and a small “panic” button.
- Smart Key Fob: These key fobs are more advanced and often have multiple buttons for various functions, including trunk release and remote start. They may also have a key blade built into the fob.

Once you’ve identified your key fob type, follow these steps to replace the battery:
1. Locate the Battery Compartment: The battery compartment is usually located on the back of the key fob. It might be a small, rectangular slot or a hinged cover.
2. Open the Battery Compartment: Use a small flathead screwdriver to gently pry open the battery compartment. If you have a hinged cover, simply open it.
3. Remove the Old Battery: The old battery should be easily visible. Use your fingers or tweezers to carefully remove it.
4. Insert the New Battery: Align the positive (+) and negative (-) terminals of the new battery with the corresponding markings inside the battery compartment. Gently push the battery into place.
5. Close the Battery Compartment: Close the battery compartment securely, making sure it clicks into place. If you have a hinged cover, ensure it is closed properly.
