Nissan Key Fob Not Working After Battery Change-2

The key fob is one of the newer technology’s perks that I particularly value. But what happens if it suddenly stops working? It’s possible, especially following a battery swap.

You are unable to unlock or start the car. However, while I have a backup key, the question remains: why does my Nissan key fob not work?

Did you know that changing the battery in your key fob may cause it to malfunction? The key fob’s electronic mechanism is automatically reset when the battery is changed.

Despite the fact that this doesn’t happen all the time, it does occasionally, and you’ll need to re-program your batteries.

Key fobs are being phased out of modern cars equipped with the newest technology in favor of keyless entry fobs. As a result, you must ensure that your key fobs are in good functioning order.

When it comes to Nissan key fobs, one of the most common causes of malfunction is a dead battery. Make sure that the key fob is working before you change the battery or have it reprogrammed by professionals.

The following are the top three:

Why is My Nissan Key Fob Not Working?

Having your key fob fail to unlock or start your automobile is the most irritating circumstance you can imagine.

The fob itself can be the culprit in some circumstances, but your battery is usually to blame. When it doesn’t work, here are a few things to consider.

1. Key Fob Battery

While a key fob might survive a long time, there is a time limit on how long it can be used.

For a properly kept automobile and key, 8 years is typical, but if you’ve been dropping the keys a little more than usual, you’ll only get 4 years out of the vehicle.

In the first place, if you find that your key fob isn’t working, it’s most likely because your battery is dead.

Detecting this problem is as simple as locating it.

Battery failure or death is the most likely cause of a non-responsive key fob. However, it’s possible that this isn’t the only explanation.

My recommendation is to open the door with your extra key. Make sure your key fob has a fresh set of batteries before proceeding.

You should be able to get aid from an aftermarket auto parts store for that. Few people would even help you change the battery. Your key fob is now fully operational once more.

You can replace the battery yourself if your local auto parts store does not offer this service. Consult your owner’s manual for instructions.

Don’t worry if you don’t have them, you can easily find one on the internet! It’s easy to find the proper battery and how to replace it with the help of the tutorial.

A frequently asked question is, “Do you have to reset a Nissan key fob if you change the batteries?”

I’m sure you’d have to, else your car’s key fob wouldn’t be able to communicate with it. In the next section, I’ll go into greater detail about this.

2. Internal Damage

The battery may not be to blame for all of the problems you’re having with your key fob. When the transmitter in the key fob and the receiver in the car interact, the key fob operates.

The transmission is disrupted if any of these are damaged, and it doesn’t work as intended.

As previously said, the problem could be with the key fob itself or with the car’s electronics.

Even if it is most likely to happen, it does not have to be limited to one person and one device. Additionally, the age of the car is a factor; if it’s older, the wiring can be worn out.

The key fob can be damaged if it is dropped or handled incorrectly in specific instances.

Even if you don’t give it much thought, it’s a piece of electronic equipment that can become out of alignment if it isn’t treated carefully.

In any event, do not try to treat this yourself if you feel internal injury is the reason.

A mechanic at your local dealership or a car locksmith are the best people to work on it. If they can’t fix it, they’ll recommend a new one.

3. Key Fob Not Programmed Or Reset

In both the conventional and modern senses, each key pair is associated with a specific lock..

Even while technological advances have altered how we view these, they remain essentially unchanged.

The new configuration has introduced an extra layer of protection that wasn’t there before. The introduction of transmitters and receivers has made it more difficult for criminals to break into a vehicle.

Using this method helps to keep the vehicle secure and safe.

However, there is a downside to this. A new key must be programmed to connect with your automobile before it can be used in your vehicle. Replacing your worn-out or lost key without reprogramming causes this problem.

Assuming you or the mechanic forget to program your key fob, it may not operate.

You should be able to have it reprogrammed by your dealership or an automobile locksmith. While hiring a locksmith is a more cost-effective alternative, make certain they are well-versed in their craft.

Reprogramming appears to be a lot of work, but it just takes a few minutes to get your automobile to recognize the key fob.

4. Damaged Ignition Cylinder

In addition to opening your car door, your key fob also serves as a starter for your automobile when used in conjunction with the ignition.

There is a matching function in the automobile that receives requests for each one in the app. Your key fob won’t work if any of its components are damaged.

A problem with the key fob is unlikely if you can access your car door but are unable to turn the ignition. Instead, it’s possible that the problem is with the ignition.

Every portion of your car that moves is vulnerable to damage over time.

Because of this, you can expect your engine to fail, and your ignition cylinder to wear out, if your vehicle is a few decades old.

There is no need to worry about the ignition or the key fob when it comes to automotive locksmiths and dealership mechanics.

It is possible to save it if it is in the early stages of deterioration. The ignition cylinder may need to be replaced if it’s in bad shape.

5. Aftermarket Car Keys

Most car owners choose aftermarket components because they are less expensive than OEM ones from the dealership.

Buying a key fob from an aftermarket auto parts store will set you back $50-$75, but you’ll pay $150-$200 at the Nissan dealership.

While the latter is the superior alternative, the former may or may not be compatible with your vehicle, depending on what has to be done.

Because of this, if you decide to purchase aftermarket parts, you must be aware of the hazards involved.

Aftermarket key fobs should also be programmed to operate with your car before being purchased. If you neglect this step, you’re asking for trouble with your vehicle.

This is due to the fact that they aren’t made for any particular brand. So, you’ll need to install additional software in order for it to work with your car.

Mechanics and locksmiths are capable of doing this for you, and it’s a simple procedure.

6. Duplicate Car Key

Everyone, including you, may have a copy of your house, locker, or even your car’s key. For the same reason, key fobs are frequently duplicated.

No one wants to be stranded in their car at dawn, unable to find their key fob. Your peace of mind and the ability to share with family members can be gained by having spare keys on hand.

Most individuals don’t aware that key fobs get less and less similar to their originals with each copy. The integrity of the original is compromised with every key that is replicated.

To put it another way, a copy of the original may be sufficient for your purposes. However, a copy of a copy is not the same as the original.

Your key fob isn’t working because it hasn’t been tampered with in any way possible.

Instead of duplicating your key fob, purchase a new one and program it to operate with your vehicle.

How To Reset Your Nissan Key Fob After Replacing The Battery

After changing a battery in your Nissan key fob, you will need to reprogram or reset it. This isn’t something that happens on a regular basis, but it does on sometimes.

How can I reset my Nissan key fob in the event that it gets lost or stolen? To be on the safe side, have the key fob reprogrammed by a locksmith or the dealership.

Step-by-step instructions are provided below for those who wish to try their hand at it.

Get into Your Nissan Car and use the Lock Switch on the driver’s side door to lock all the doors.

Remove the key from the ignition. Do this six times in a row, each time taking precisely ten seconds. Before putting it back in, make sure you remove it completely from the ignition. Do not start the engine.

Your first step into programming mode is to click on this link. This will cause both the outside and interior lights to flash twice if it is successful.

Insert the key into the ignition a second time and turn the key to the Accessories mode after entering the programming mode.

To use the key fob, simply press any key on the fob once. Attempt it only once.

If everything goes according to plan, the key fob should be ready for programming at this point. Once this was confirmed, the hazard lights would come on.

Get out of the car by turning off the ignition and removing the key fob from the ignition.

Try unlocking the door using the key fob.

If the steps outlined above are unsuccessful, try them again. Contact your local Nissan dealer if you keep getting the same error message.

Take a look at this video I found:

Nissan Altima

The first Nissan Altima went on sale in 1993. All versions before to 2007 can be programmed using the above techniques.

There is nothing you can do yourself after 2007, as it is no longer programmable onboard. Your dealership or a car locksmith must perform this service.

Nissan Juke

It wasn’t until 2011 that Nissan unveiled the Juke. As with the Altima, you can follow the above steps to program your key fob for models prior to 2013.

A skilled specialist utilizing specialized computer equipment will have to make the key fob starting in 2014.

Nissan Morano

If you have a key fob that can be programmed on the vehicle, the Nissan Murano was released in 2003.

To reprogram your key fob, you’ll need a computer that’s specifically designed for that purpose; a locksmith, mechanic or car dealership can assist you.

Nissan X-Trail

According to my understanding, the standard key fobs have been replaced by keyless clever smart fobs in contemporary Nissan vehicles.

It’s possible that you’ll need the services of an automotive locksmith if you own a later model vehicle.

How Much Does it Cost to Replace The Nissan Key Fob Battery?

Autozone and Batteries Plus have it for $6 and $7.99, respectively. Prices vary depending on the make and model of automobile, as well as the type of remote.

Changing the battery is as cheap as buying a new one if you know how to do it yourself. However, traveling to a dealership to have the batteries changed for you will cost you a lot of money.
