How to Change Battery Nissan Altima Key Fob

If you’re experiencing issues with your Nissan Altima key fob, like decreased range or unresponsive buttons, it might be time for a battery replacement. Thankfully, changing the battery in your Nissan Altima key fob is a quick and easy process you can do yourself. This guide will walk you through the steps for different Nissan Altima model years, ensuring your key fob is back to working order in no time.

Identifying Your Nissan Altima Key Fob Type

Before you begin, it’s essential to identify which type of key fob your Nissan Altima uses, as the process can slightly differ between models. Generally, there are two main types:

• Standard Key Fob with Flip Key: This type has a flip-out key blade and separate lock, unlock, panic, and trunk buttons.
• Smart Key Fob (Keyless Entry): This type might have a hidden key blade, and the buttons control functions like remote start, proximity lock/unlock, and panic.

Once you’ve identified your key fob type, gather the following tools:

• A small flat-head screwdriver
• A new CR2032 battery (most common type for Nissan key fobs)

Changing the Battery in a Standard Nissan Altima Key Fob

For this guide, let’s assume you have a 2016 Nissan Altima with a standard key fob. Here’s how to change the battery:

1. Locate the Key Release Button: On the back of your key fob, find the small button. Press it to release the metal key blade.
2. Open the Key Fob: Using your fingernail or the flat-head screwdriver, carefully pry open the key fob casing along the seam where the metal key was released. You should hear a slight click when it separates.
3. Replace the Battery: Inside the fob, you’ll see the CR2032 battery. Carefully remove it, noting the positive (+) side facing up. Insert the new battery in the same orientation.
4. Reassemble the Key Fob: Align the two halves of the key fob and press them together until you hear a click, indicating it’s securely closed.
5. Reinsert the Key Blade: Slide the metal key blade back into its slot until it locks in place.
6. Test the Key Fob: Check if all the buttons are working correctly.

Changing the Battery in a Smart Key Fob

If you have a newer Nissan Altima with a Smart Key Fob, the process is slightly different:

1. Locate the Emergency Key Slot: On the back of your key fob, find a small slot.
2. Release the Emergency Key: Insert the flat-head screwdriver (or a similar tool) into the slot and gently pry open the small cover to reveal the emergency key blade.
3. Open the Key Fob: With the emergency key cover removed, you’ll see a small gap. Insert the flat-head screwdriver into this gap and gently pry open the key fob casing.
4. Replace the Battery: Inside, locate the CR2032 battery and replace it with the new one, ensuring the positive (+) side faces up.
5. Reassemble the Key Fob: Align the key fob halves and press them together until they click shut.
6. Reinsert the Emergency Key Cover: Slide the cover back into place until it snaps securely.
7. Test the Key Fob: Ensure all buttons function correctly, including proximity lock/unlock and remote start (if equipped).

Troubleshooting Tips

If your key fob isn’t working even after replacing the battery, try these steps:

• Check Battery Orientation: Make sure the new battery is inserted correctly with the positive (+) side facing up.
• Clean the Battery Contacts: Use a cotton swab and rubbing alcohol to clean the battery contacts inside the key fob.
• Reprogram the Key Fob: Some Nissan models might require you to reprogram the key fob after a battery replacement. Refer to your owner’s manual for specific instructions.
