Easy Steps to Change Battery Nissan Key Fob?

If your key fob has stopped working, it may be that you simply need to change the battery. Don’t worry, though—it’s a simple procedure that anyone can do! Here’s what you’ll need:

Step 1: Remove the hidden key from its place in the key fob. You’ll find it by pulling out on the tab on the bottom half of your fob, where you would press if you were unlocking your door. Once you pull out on that tab, you will see a small key attached to a metal loop. Pull it out and set aside.

Step 2: Remove the rear key housing and remember its position. You’ll remove it by pulling it away from the front piece, which houses your keyless entry buttons. If you look at this piece more closely, you will see that one side is curved and one side is flat. Make sure when reassembling it that this piece is placed correctly so that it snaps back into place easily.

Step 3: Remove the old battery and pop in the new battery. The battery should fit snugly into place without having to be forced in any direction. Do not press on glass covering the battery or damage could occur.

Step 4: Inserting a new battery is like putting together a sandwich: make sure the negative sides face each other, with positive sides touching their respective pieces

Things to keep in Mind While doing Nissan Key Fob Battery Replacement

When it comes to replacing your Nissan key fob battery, the process is pretty straightforward. But there are a few things that you should keep in mind when doing so:

  1. When opening the casing into two parts, don’t use the grooves on the side of the casing as a point to lever your screwdriver. Older keys have these side grooves, but ignore those and focus on the slits at the top instead.
  2. When prying open the casing from the top, don’t apply too much force in case you cause any damage to the casing edge or any parts of its innards.
  3. Don’t put your key fob near anything magnetic while you’re changing the battery. Magnets can cause damage to the internal workings of your Nissan key fob.
  4. When replacing the battery, ensure that you put the side with the writing on it “Panasonic CR 2032…” face down into the battery casing. If you put it in the wrong way, it won’t work!

What to do if your Battery Dies in Middle of the Way?

Most Nissan vehicles come with a key fob that allows you to push a button to lock and unlock your doors, as well as start your vehicle. It’s a convenient item that can make getting in the driver’s seat a quick and easy process.

So what happens if your battery dies? You will still have access to your vehicle, but it might take you a little longer.

Once your battery dies, you will obviously need to replace it; however, you need your vehicle to get you to the store. Every Nissan key fob has a backup key inside that will allow you to get inside. You will notice a small release latch that allows you to pull out the backup key. Open your door and jump inside. If your Nissan doesn’t have a physical ignition hole, just place the key fob up against the start/stop button and start your vehicle.

How often do you need to change battery in Nissan key fob?

When it comes to the lifespan of your key fob battery, there is some good news. You don’t have to replace the battery often. The average life of a Nissan key fob battery is between three and four years, with heavy use shortening that span a bit. If you are using remote functions like locking and unlocking your car from afar often, then this will put more wear on the battery.

But even so, you shouldn’t have to worry about changing it every year or even every other year. If you’re using your fob frequently, then you may be able to squeeze out another year or two before needing a replacement.


Without a key, you are basically just a passenger in your vehicle. You won’t be able to start the engine or unlock the doors, so you might as well sit back and enjoy the ride.

Overall it’s better to keep your key fob healthy and change the battery when needed. Don’t get too worried if it breaks one day as you can always get temporary use by calling Nissan roadside assistance and request a remote unlock.

They’ll send over a different key fob to you or have a mechanic assist you while you troubleshoot the issue on your own. This should work in a pinch until you can get the proper replacement key fob from Nissan.
