Why You Need to Replace the Battery in Your Nissan Key Fob
Here are some of the benefits of having a working key fob for your Nissan vehicle:
Key Fob Functionality:
Your key fob lets you perform various functions remotely, such as locking and unlocking the doors, opening the trunk, activating the alarm, and starting the engine.
These functions make your driving experience easier and more comfortable.
Avoiding Unexpected Lockouts:
Imagine if you left your keys inside your car and locked yourself out. That would be a nightmare, right? Well, with a working key fob, you don’t have to worry about that.
You can always unlock your car from a distance using the remote buttons on your key fob.
Preventing Signal Weakness:
If your key fob battery is low, you might notice that the signal strength is weak or inconsistent.
This means that you have to be closer to your car or press the buttons harder to make them work.
This can be frustrating and inconvenient, especially if you are in a hurry or in a crowded parking lot.
Maintaining Security Features:
Your key fob also helps protect your car from theft and vandalism.
It has a built-in immobilizer system that prevents the engine from starting without the correct key fob.
It also has a panic button that triggers the alarm and flashes the lights if you feel threatened or need assistance.
Enhancing Remote Start Performance:
If you have a remote start feature on your Nissan vehicle, you can start your engine from afar using your key fob.
This is especially useful in cold or hot weather, as it allows you to warm up or cool down your car before getting in.
If your key fob battery is low, you might experience delays or failures in starting your engine remotely.
Extending Key Fob Lifespan:
Replacing your key fob battery regularly can also help extend the lifespan of your key fob.
If you let your battery drain completely, it might damage the internal components of your key fob or cause corrosion.
This can affect the performance and durability of your key fob and might require you to buy a new one.
Ensuring Smooth Keyless Entry:
Some Nissan vehicles have a smart key system that allows you to enter and start your car without inserting a key.
All you have to do is have your key fob in your pocket or purse and touch the door handle or push button ignition.
This is very convenient and hassle-free, but it also depends on having a good battery in your key fob.
What Type of Battery Does Your Nissan Key Fob Use?
The type of battery that your Nissan key fob uses depends on the model and year of your vehicle. Most Nissan key fobs use one of these three types of batteries:
Lithium Coin Cell Batteries:
These are small, round, silver batteries that look like coins. They have a high energy density and long shelf life.
They are also lightweight and compact, making them ideal for small devices like key fobs. Most Nissan key fobs use either a CR2025 or CR2032 lithium coin cell battery.
These are common household batteries that come in different sizes and shapes.
They have a lower energy density and shorter shelf life than lithium batteries, but they are cheaper and more widely available.
Some older Nissan key fobs use an A23 alkaline battery.
These are batteries that can be recharged using an external power source.
They have a higher energy density and longer lifespan than alkaline batteries, but they are more expensive and require a charger.
Some newer Nissan key fobs use a rechargeable lithium-ion battery.
How to Replace the Battery in Your Nissan Key Fob?
The Nissan key fob battery is easy to replace. You just need a screwdriver or a coin and some minutes. Here are the steps to follow:
Opening the Key Fob:
The first step is to open your key fob and access the battery compartment.
Depending on the type of key fob you have, you might need to remove or flip out the emergency key first.
Then, insert the screwdriver or coin into the small slot at the bottom of the key fob and twist until it pops open.
Be careful not to damage the plastic casing or the internal circuit board.
Removing the Old Battery:
The next step is to remove the old battery from the key fob. Use the screwdriver or coin to gently pry out the battery from its holder.
Make sure to hold the battery by its edges and avoid touching the terminals or the circuit board. Dispose of the old battery properly and safely.
Inserting the New Battery:
The final step is to insert the new battery into the key fob. Make sure that the positive side (+) of the battery is facing down and matches the polarity of the holder.
Press the battery firmly into place until it snaps in. Do not force or bend the battery, as this might damage it or cause leakage.
Closing the Key Fob:
The last thing to do is to close your key fob and test it. Push the two halves of the key fob together until they click.
Then, try using your key fob to lock and unlock your car doors, open the trunk, start the engine, etc.
If everything works fine, congratulations! You have successfully replaced your Nissan key fob battery.
Tips for Extending the Battery Life of Your Nissan Key Fob
Here are some tips that can help you extend the battery life of your key fob and save money and time:
Proper Storage Techniques:
One of the best ways to preserve your key fob battery is to store it properly when not in use.
Keep your key fob away from direct sunlight, heat sources, moisture, dust, and magnetic fields. These factors can drain or damage your battery over time.
Also, avoid dropping or hitting your key fob, as this might crack or loosen its casing or components.
Minimal Usage During Long Periods:
Another way to prolong your key fob battery is to use it sparingly during long periods of inactivity.
If you are not going to drive your car for a while, such as during a vacation or a lockdown, try not to use your key fob too much.
This will prevent unnecessary power consumption and signal transmission.
You can also remove the battery from your key fob and store it separately until you need it again.
Regular Cleaning and Maintenance:
A third way to extend your key fob battery is to clean and maintain it regularly.
Dirt, grease, corrosion, or oxidation can affect the performance and lifespan of your battery and key fob.
To prevent this, wipe your key fob with a soft cloth every once in a while and check for any signs of damage or leakage.
If you notice any problems, replace your battery or key fob as soon as possible.
Avoiding Exposure to Extreme Temperatures:
A fourth way to extend your key fob battery is to avoid exposing it to extreme temperatures.
High or low temperatures can reduce the capacity and efficiency of your battery and cause it to drain faster or fail prematurely.
To avoid this, do not leave your key fob in hot places like inside a car under direct sunlight or near a heater.
Do not leave your key fob in cold places like outside in freezing weather or near an air conditioner.
Battery Testing and Replacement Schedule:
A fifth way to extend your key fob battery is to test and replace it according to a schedule.
You can also test your key fob battery yourself by using a voltmeter or a multimeter.
If the voltage is below 3 volts, it means that your battery is low and needs to be replaced.
You can also follow a general rule of thumb and replace your key fob battery every two to three years, depending on how often you use it.
Using High-Quality Batteries:
A sixth and final way to extend your key fob battery is to use high-quality batteries from reputable brands.
Cheap or counterfeit batteries might not have the same specifications or quality standards as the original ones and might not work well or last long.
They might also leak or explode and damage your key fob or harm you. Therefore, always buy genuine batteries from authorized dealers or online stores.
