How to Replace Your 2009 Nissan Sentra Key Fob Battery (Step-by-Step)

Replacing the key fob battery is a straightforward process that most people can handle with a few basic tools. Here’s a step-by-step guide:

Locate the Key Fob’s Groove: Examine your key fob for a small groove or notch. This is usually located on the side or back.
Open the Key Fob: Insert a small flathead screwdriver (or a coin, if the groove is wide enough) into the groove and gently twist or pry open the key fob casing. Be careful not to use excessive force to avoid damaging the casing.
Identify and Remove the Old Battery: Inside the casing, you’ll see the battery. Carefully remove it, noting the orientation (positive (+) side up).
Insert the New Battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side faces up, just like the old battery.
Close the Key Fob: Align the two halves of the key fob casing and press them firmly together until you hear a click, indicating it’s securely closed.
Test the Key Fob: Try locking and unlocking your car using the key fob to make sure the new battery is working correctly.
