A dead key fob battery can leave you stranded and frustrated. Thankfully, replacing it is usually a quick and easy process you can do yourself. This guide provides a step-by-step walkthrough on how to replace the battery in your Nissan key fob, saving you a trip to the dealership and keeping you on the move.
Identifying Your Nissan Key Fob Type
Before you get started, you’ll need to determine which type of Nissan key fob you have. This will help you gather the correct replacement battery and tools for the job. There are two main types of Nissan key fobs:
- Standard Key Fob: This traditional fob features a physical key blade that folds out and buttons to lock/unlock doors and activate the panic alarm.
- Smart Key/Keyless Entry Fob: This newer style typically has a sleeker design and may not include a visible key blade. Smart keys allow you to unlock and start your vehicle without taking the fob out of your pocket or purse.
Once you’ve identified your key fob type, you can move on to gathering the necessary materials.
What You’ll Need:
- Replacement Battery: Most Nissan key fobs use a CR2025 or CR2032 battery. Refer to your owner’s manual or search online for your specific Nissan model to confirm the correct battery type.
- Small Flat-Head Screwdriver: This is used to separate the key fob casing.
- Optional: A small container or tray to keep the battery and small parts organized.
Replacing the Battery in a Standard Nissan Key Fob
- Locate the Release Button or Notch: On the back of the key fob, find the small button or notch. This is usually located near where the physical key blade folds out.
- Release the Key Blade: Press the release button or insert your fingernail into the notch and gently swing the key blade out to expose the battery compartment.
- Separate the Fob Halves: Carefully insert the flat-head screwdriver into the seam between the two halves of the key fob. Gently pry the halves apart. Avoid using excessive force, as this could damage the fob.
- Remove and Replace the Battery: Gently pry out the old battery and note its orientation (+/-). Insert the new battery, ensuring it matches the same orientation as the old one.
- Reassemble the Key Fob: Align the two halves of the fob and press them firmly together until you hear a click, indicating they are securely closed.
- Test the Key Fob: Try locking and unlocking your car doors and using other functions to ensure the new battery is working properly.
Replacing the Battery in a Nissan Smart Key Fob
Smart key fobs have a slightly different process for battery replacement:
- Locate the Emergency Key Slot: Look for a small slot on the fob, usually on the side or back.
- Release the Emergency Key Blade: Insert a small flat-head screwdriver or a similar object into the slot and gently slide the emergency key blade out.
- Open the Battery Compartment: With the emergency key blade removed, you’ll see a small notch or opening. Use your fingernail or the tip of the screwdriver to pry open the battery compartment cover.
- Remove and Replace the Battery: Gently pry out the old battery and note its orientation. Insert the new battery, making sure it matches the same orientation.
- Close the Battery Compartment: Snap the battery cover back into place.
- Reinsert the Emergency Key Blade: Slide the emergency key blade back into its slot until it locks in.
- Test the Key Fob: Ensure the new battery is working correctly by trying to lock and unlock your doors and start the vehicle.
Still Having Trouble?
If you’re still experiencing issues with your Nissan key fob after replacing the battery, you may need to have it reprogrammed or inspected for other potential problems. In these cases, it’s best to consult a qualified automotive locksmith or your local Nissan dealership for assistance.
“Sometimes, a simple battery replacement isn’t enough,” says John Smith, a certified automotive locksmith with over 15 years of experience. “If your Nissan key fob isn’t functioning correctly after a battery change, there could be a programming issue or a problem with the fob itself.”

Replacing the battery in your Nissan key fob is a straightforward task that can save you time and money. By following these simple instructions and taking proper precautions, you can get back on the road quickly and confidently. Remember to always refer to your owner’s manual for specific instructions related to your Nissan model.
