Gathering the Necessary Tools
Replacing the battery in your Nissan Altima key fob requires minimal tools:

Step-by-Step Guide to Replacing the Battery
Here’s a general guide, but remember that the exact procedure might differ slightly depending on the year of your Nissan Altima. Always consult your owner’s manual for model-specific instructions.
- Locate the Key Release: On most Altima key fobs, there’s a small button or switch. Press it to release the valet key.
- Open the Key Fob: Use the flathead screwdriver to carefully pry open the key fob casing. Start at the seam where the two halves of the fob meet. Insert the screwdriver gently to avoid damaging the plastic.
- Remove the Old Battery: Once the fob is open, you should see the battery. Gently pry it out using your flathead screwdriver or your fingernail. Avoid puncturing the battery.
- Install the New Battery: Insert the new battery, making sure the positive (+) side faces up, just like the old battery.
