The battery on the Nissan Smart Key
For many years now, Nissan has been using Smart Keys instead of standard ignition keys for their vehicles. The Nissan Intelligent Key System allows drivers to lock and unlock the car doors at a distance, open the trunk, and start the car with the push of a button.
As the automotive industry moves more and more towards technology like Smart Keys, there are always concerns that come along with the progress. For example, what are you supposed to do if the battery in the Nissan Smart Key dies? What kind of battery does the little key fob even take?
All modern Nissan cars, trucks, and vans use the same Smart Key fob and, therefore, the same battery. Inside each Nissan key fob, you will find a single CR2032 3-volt disc-shaped battery. You can find these batteries in most places where batteries are available for sale or in online marketplaces like Amazon.
While this battery size is the type you’ll find in most Nissan Smart Keys, there is a chance you could have a variation, especially if you are driving an older Nissan. So, always match the old battery you are removing from the key fob with the new one.
Changing the Battery on the Nissan Smart Key
Changing the batteries on small electronic devices like watches or hearing aids is often tricky and frustrating. Luckily, Nissan makes changing the battery on their Smart Key fobs pretty simple. The only tricky part is getting the key fob to open without damaging it. With that said, we will now give a more detailed description of the battery-changing process.
Step 1: Remove the Valet Key
Every Nissan Smart Key fob has a small standard (old-fashioned) key inside of it. This extra key is called a valet key and is used in a pinch if your key fob battery is dead. This is also the key that you can pull out of the fob and leave with the valet so you can hold onto your actual fob.
To change the battery on your Nissan key fob, you’ll need first to remove this valet key. You can remove the valet key by sliding the small button on the back of the fob and pulling the key out by the key ring.
Step 2: Open the Key Fob
Next is the most challenging part. actually opening the key fob so that you can access the battery. Nissan Smart Key fobs are split around the perimeter so that they can open up almost like a clamshell.
The best way to go about separating the fob is to use a flat head screwdriver or a thicker card to pry it open a little at a time, starting in the top right corner where there’s a small gap about the size of the head of your screwdriver.
Work your way around the edge of the fob in between the two halves until you hear a click. That click will mean that you have successfully opened the fob.
Step 3: Battery Replacement
Finally, you will see the battery sitting facedown in its compartment on one side of the key fob. Using the screwdriver or card, gently pry the old battery out of its place. Next, please verify that you have the correct size of the new battery (CR2032) and place it face down in the battery compartment.
Step 4. Resassemble the Fob
You have to put the fob back together for the last step, so it’s in working order. After verifying that the new battery is securely in its place, the two halves of the key fob should snap back together as long as they are aligned. After that, replace the valet key in its slot. Now you’re good to go.
Because opening the hard plastic key fob is such a delicate process, it might be helpful to see a video of someone opening one. So, here is a quick YouTube video that explains how to change the battery in a Nissan Smart Key:
How To Change The Battery In A Jeep Key Fob? Detailed Guide
One day you realize that your key fob is not working as flexibly as before, and you think the cause is the battery drain. Let’s follow us to reach a step by step guide.
When Does The Key Fob Battery Need Replacing?
Shortened Signal Range
Normally, the key fob’s operating range of receiving signals is 20m. If you see this distance decreasing over time, your key fob has a problem. One common reason is that your battery is depleted or dead and needs to be replaced.
However, the rain sometimes affects the car remote’s ability to receive signals. On rainy days, if you have to approach the car to turn on the key fob, and the distance is still well maintained for the rest of the day, it is not a big problem.
In addition, a damaged remote transmitter or receiver also prevents the car box from catching the signal from the key. Chip failure or broken circuit in the remote battery makes it completely useless.
Common signs are headlights don’t flash or don’t even turn on, and there is no signal sound when pressing the button.
Over-Clicking
You own a weak battery if you have to press the key fob button panel too many times to unlock it. After a long time being used, the key fob will gradually run out of battery or have an internal battery failure. The battery installation area also has problems, such as a short circuit.
Cracks next to the installation area will hinder the battery from being correctly installed and cause a non-working Jeep key fob. It can shorten the battery’s life and cause it to drain more quickly.
over, when you press the unlock button on the key fob too many times but the indicator light keeps blinking and then turns off, your battery is completely “exhausted”. It would be best if you asked someone else to bring you the backup key.
Delayed Unlocking
Receiving a slow signal is a common pointer of a key fob running out of battery. The key fob normally responds by turning on the car indicator light to inform you of the successful unlocking process.
However, if it responds slowly, about 5-10 seconds after you press it, the signal source it sends is too weak due to a drained battery.
This case is not always derived from a dead battery but can happen in case of faulty key fob programming. After replacing a coin battery, if your car remote does not respond as quickly as before, you should ask a car mechanic to reprogram the key.
