This comprehensive guide will walk you through the process of how to change key fob battery Nissan Sentra, step-by-step.

Gather Your Supplies

Before you start, you’ll need a few things:

• A new CR2032 battery: This is the standard battery used in most Nissan Sentra key fobs. You can find them at most electronics stores, supermarkets, and online retailers.
• A small flat-head screwdriver: This will be used to pry open the key fob.
• A small coin or a thin, flat object: This is optional but can be helpful for pushing the battery release button.

Locate the Battery Compartment

The first step is to locate the battery compartment on your key fob. It’s usually on the back of the fob, near the Nissan logo. If you can’t find it, refer to your car’s owner’s manual for specific instructions.

Open the Key Fob

Once you’ve located the battery compartment, you’ll need to open it. This is usually done by using a small flat-head screwdriver to pry open the key fob. There might be a small seam or groove around the edge of the fob where you can insert the screwdriver. Be careful not to apply too much force, as you don’t want to damage the key fob.

Remove the Old Battery

Once the key fob is open, you’ll see the old battery. It might be held in place by a small spring or clip. Gently remove the battery, making sure to note its orientation (positive and negative sides).

Insert the New Battery

Now, take your new CR2032 battery and insert it into the battery compartment, ensuring it’s correctly aligned with the positive and negative terminals. The battery should snap into place.

Close the Key Fob

Once the new battery is in place, close the key fob. You should hear a click as it snaps shut. If it doesn’t close easily, double-check that the battery is properly seated.

Test the Key Fob

After replacing the battery, test the key fob to ensure it’s working properly. Try locking and unlocking your car, and make sure the remote start function is working.

Tips for Extending Battery Life

Here are a few tips to help extend the life of your key fob battery:

• Avoid extreme temperatures: Keep your key fob away from extreme heat and cold, as these can damage the battery.
• Don’t expose it to moisture: Avoid getting your key fob wet, as this can also damage the battery.
• Avoid unnecessary button presses: Only press the buttons on your key fob when necessary, as this can drain the battery faster.
• Store it properly: When not in use, store your key fob in a cool, dry place.

Taking Care of Your Key Fob

• Keep it clean: Wipe down your key fob regularly with a soft cloth to remove dirt and grime.
• Avoid dropping it: Dropping your key fob can damage the internal components, including the battery.
• Don’t leave it in direct sunlight: Prolonged exposure to direct sunlight can damage the key fob’s plastic casing.

• The new battery is defective: Try a different battery.
• The key fob is damaged: If the key fob has been dropped or damaged, it might need to be repaired or replaced.
• The key fob is not programmed to your car: If you’ve recently bought a used key fob, it might need to be programmed to your car. You can usually find instructions for programming your key fob in your car’s owner’s manual.
