How to Change the Battery in a Nissan Key Fob

Changing the battery can be a little bit advanced and technical but nothing to worry about. Anyone with the right information should be able to do it.

Just like any other device, it’s very important to know when and how to change the battery in a Nissan key fob because of its limited battery lifespan.

We have outlined six (6) easy steps for you on how to change the battery in a Nissan key fob.

Step 1: Find and Release the Mechanical Key.

The first step is to turn the Nissan key fob over and find the little release catch on the back.

Now, carefully pull it down and it will release the stored mechanical key from its position in the fob. Remove the key. This key is not a part of the battery replacement process, but it needs to be out of the way.

Step 2: Open the fob into Two Parts

Directly at the top end of the key fob, you will see two small slits. It is ideal and advisable to slot a small flat-head screwdriver before turning it clockwise to safely and evenly open the casing.

By doing this, you should be able to pull the fob into two halves. It should look like the picture above.

Step 3: Remove the Old Battery

The Nissan key fob battery is a round Panasonic 3-volt CR 2032 battery. You should see its metal disc sitting in one half of the key fob. Gently use a small flat-head screwdriver (the same one you used in step 2) to pop the battery out safely.

A small gap should be seen under the battery perfect to suit this movement.

Step 4: Install the New Battery

Now, take your new Nissan CR 2032 battery and place it with the writing on the battery facing downward. Gently and carefully slide it in from the side towards the spring visible in the casing.

Carefully push the battery toward the spring and ensure that it clicks and fits properly into place.

Step 5: Replace Key Fob Housing

In this step, you need to put the two pieces of the key fob casing you earlier removed back together.

Now, you have to line up the two halves and click them back into place. You should hear a loud or at least noticeable click, so ensure that all the parts are evenly connected.

Step 6: Replace the Mechanical Key

At this final step, all you have to do is put the spare mechanical key back in its slot and your Nissan key fob battery should be working fine again.

How Frequently Should You Change the Battery in a Nissan Key Fob?

Your Nissan key fob battery is designed to last between three to four years requiring a change.

However, if you use the key fob and its remote functions regularly, the tendency that the battery lifespan will diminish quickly is very high and will not last as expected.

Regardless, it is still expected to reach the lower estimate of the three to four years. Where you store your key fob could also affect the battery life.

How Much does it Cost to Replace a Nissan Key Fob Battery?

Replacing your Nissan key fob battery yourself is relatively easy and the batteries are quite affordable.

The cost of a Nissan key fob battery is relatively cheap. You can find a replacement battery for your Nissan at almost any store or online for $2 to $5.

You can also take the key fob to a dealer and have them do a Nissan key fob battery replacement for you for a token, but this service isn’t necessary.
