How to Replace the Battery in a 2003 Nissan Altima Key Fob: Step-by-Step
Step 1: Locate the Key Fob Release Button
On the back of your key fob, you’ll find a small button. This button releases the physical key hidden inside.
Step 2: Release the Physical Key
Press the release button and gently slide the physical key out of the fob.

Inside the key fob, you’ll see the battery, which is typically a CR2025. Carefully remove the old battery and replace it with the new one, ensuring the positive (+) side faces up.

Align the two halves of the key fob casing and press them firmly together until you hear a click, indicating it’s securely closed.
Step 6: Test the Key Fob
Try locking and unlocking your car doors using the key fob to make sure the new battery is working correctly.
