How To Change Key Fob Battery Nissan?

Changing the battery in your Nissan key fob is a simple process that you can complete at home with a few basic tools. Below are the detailed steps to guide you through the process.

Step 1: Gather Your Tools and Supplies

Before you begin, make sure you have the following items:

• A new CR2032 battery
• A small flat-head screwdriver

Step 2: Remove the Mechanical Key

Locate the small latch or button on the back of the key fob, usually near the keyring hole. Press this latch and pull out the mechanical key that’s inserted into the fob. This will expose a small slot on the fob where you can insert the screwdriver.

Step 3: Pry Open the Key Fob

Insert the flat-head screwdriver into the slot exposed by the removal of the mechanical key. Gently twist the screwdriver to separate the two halves of the key fob. Be careful not to use excessive force, as you could damage the plastic casing.

Step 4: Remove the Old Battery

Once the key fob is open, you’ll see the old battery. It’s usually held in place by small plastic clips. Use the screwdriver to gently release these clips and remove the old battery. Take note of the orientation of the battery, as you’ll need to place the new one in the same way.

Step 5: Insert the New Battery

Place the new CR2032 battery into the battery compartment, making sure to orient it the same way as the old battery. The positive side, usually indicated by a “+” symbol, should be facing up or down based on how the old battery was oriented.

Step 6: Reassemble the Key Fob

Once the new battery is securely in place, align the two halves of the key fob and gently snap them back together. Make sure the casing is tightly sealed to prevent any dirt or moisture from entering.

Step 7: Reinsert the Mechanical Key

Slide the mechanical key back into its slot until it clicks into place. This ensures that you have a manual way to unlock your car in case the battery dies unexpectedly.

Step 8: Test the Key Fob

Finally, test the key fob to make sure it’s working correctly. Stand near your vehicle and press the unlock button. If the doors unlock and the lights flash, you’ve successfully changed the battery.

How to Extend Battery Life?

Extending the battery life of your Nissan key fob can save you both time and money in the long run. Here are some effective ways to prolong the lifespan of your key fob battery:

Limit Remote Use

• Explanation: The more frequently you use the remote functions of your key fob, like unlocking/locking doors or activating the trunk release, the quicker the battery will drain.

Proper Storage

• Explanation: Extreme temperatures, both hot and cold, can affect battery performance. Storing your key fob in a cool, dry place can help extend its battery life.

• Tip: If your key fob doesn’t have an indicator, make it a habit to replace the battery every couple of years as a preventive measure.

Turn Off Extra Features

• Explanation: Some key fobs come with additional features like a flashlight or a panic button. Using these features frequently can drain the battery quickly.
• Tip: Use these features only when necessary to conserve battery life.

Keep a Spare

• Explanation: Having a spare key fob can help you alternate between them, effectively extending the battery life of each.
• Tip: If you have two key fobs, switch to the spare one every few months to balance the usage and extend the battery life of both.

Avoid Pressing Buttons Accidentally

• Explanation: Sometimes, the buttons on the key fob can get pressed accidentally when in your pocket or bag, leading to unnecessary battery drain.
