Replacing your 2008 Nissan Altima key fob battery is a quick and easy DIY project. Here’s what you need to do:
1. Gather Your Supplies
- Replacement Battery: You’ll need a CR2025 or CR2032 battery (check your owner’s manual or the back of your existing battery). These are readily available at most auto parts stores, big-box retailers, and online.
- Small Flathead Screwdriver: This will be used to pry open the key fob casing.

2. Open the Key Fob
- Locate the small groove or notch on the side of your key fob.
- Gently insert the flathead screwdriver or plastic pry tool into the groove.

3. Replace the Battery
- Once open, you’ll see the battery located inside, usually secured in a small compartment.
- Carefully remove the old battery by gently prying it out with your fingernail or the flathead screwdriver.
- Insert the new battery, making sure to match the positive (+) and negative (-) terminals with the corresponding markings on the key fob casing.
4. Reassemble the Key Fob
- Align the two halves of the key fob casing and press them firmly together until you hear a click, indicating they are securely closed.
5. Test the Key Fob
- Test all the buttons on your key fob (lock, unlock, panic, trunk release) to ensure they are functioning correctly.
