Why Is Infiniti Key Fob Not Working After Battery Change?


July 10, 2022

The key fob is one of the newer innovations that you may appreciate for its ease but what if the Infiniti key fob not working after battery change.

That’s possible, especially after a battery change, for it to happen.

You are unable to unlock or start the car.

Did you know that changing the batteries in your key fob can cause it to stop working?

It’s because the key fob’s electronic mechanism is automatically reset when the battery is replaced.

This doesn’t happen all the time, but if it does, 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, which are becoming more commonplace these days.

As a result, you must ensure that your key fobs are in working order.

When a Nissan key fob fails, the most typical reason is a faulty battery.

Test the key fob to ensure that it is operational before replacing the battery or having it reprogrammed by a qualified technician.

What’s Wrong With My Nissan Keyfob?

When your key fob stops working properly, it’s impossible to imagine a more frustrating situation than being unable to open or even start your car.

The problem may occasionally be caused by the fob itself, but in the vast majority of cases, it is due to a problem with your battery.

Should your initial choice prove unsuccessful, the following may be one of the possibilities:

1. Key Fob Battery

Even though your key fob can prolong for a longer length of time, it is not impenetrable and has a shelf life.

If you have a properly maintained automobile and key, you can expect them to last 8 years on average.

However, if you have been losing your keys more frequently than usual, you will be fortunate if your car and key last 4 years at the most.

When you discover that your key fob is no longer functioning, the first thing to keep in mind is that your battery has died or that the battery in your key fob no more has enough juice to function effectively.

Identification of this problem is a straightforward task because of its broad nature.

If your key fob is not responsive to your commands or the controls on the key fob, it is probable that the battery has failed or is entirely dead by this point, and the only solution is to replace it.

This may not be the only answer, though, and there are probably others.

Consequently, it is suggested that you try to access the door using your spare key if this is possible.

It is necessary to change the battery in your key fob if this technique was effective.

If that is the case, you should be able to seek help from any aftermarket auto parts store.

Moreover, just a few people will go to the trouble of changing your battery.

Your key fob’s operation and functionality have been fully restored.

It is possible to change a battery on your own if your local auto parts shop does not offer this service.

You can use the owner’s manual to guide you through the process.

There is no need to be alarmed if you don’t have either; you can easily obtain one by conducting a simple internet search.

By following the instructions in the guide, you will be able to select the correct battery and learn how to change it.

Another frequently asked issue is whether or not a Nissan key fob needs to be reconfigured after a battery replacement?

Your key fob will not work properly unless you do this.

2. Damage Internally

A faulty battery is not always the cause of problems; internal damage to the key fob can also be the cause of some.

Communication between the key fob and its receiver in the car is necessary for it to function properly.

If any of these components is compromised, communication is disrupted, and the system does not function as intended.

As previously stated, it is possible that the key fob has suffered internal damage, or that there is a problem with the electronics in the vehicle.

Even while this is the most typical scenario, it does not have to be limited to just the transmitter and receiver.

The age of the car also plays a role; if the vehicle is old, the connectors may have begun to deteriorate and need to be replaced.

When the key fob is mishandled, it may cause damage.

While you may not give it much thought when you drop it from time to time, it is an electronic device that, if not handled carefully, can become misaligned and malfunction.

Do not try to restore internal damage on your own if you suspect that it is the source of the problem.

Making use of the services of an automotive locksmith or mechanic at your dealership is the way to go.

They may be able to fix your fob, or they may advise that you get a new one if that is not possible.

3. Key Fob Has Not Been Reset Or Programmed

No matter how you look at it, every key pair refers to a specific lock, whether you use the term in its traditional sense or its contemporary use.

These have remained substantially unchanged, even though new findings have transformed our understanding of them.

The way it is currently has provided an added level of security that was previously lacking.

Because of the availability of transmitters and receivers, the way the car locks has changed, making it more difficult to break in.

This contributes to the overall safety and security of the vehicle.

However, there is a disadvantage to doing so.

Any new key must be configured so that it can connect with your vehicle.

This problem occurs when you replace a worn-out or lost key and then forget to program the new key in its position.

If your key fob is not functioning, there is a possibility that you or the mechanic has forgotten to program the device.

It should be possible to have it reprogrammed through your dealership or an automotive locksmith.

Whilst the locksmith is a more convenient and cost-effective choice, make certain that they are knowledgeable in their field.

Reprograming appears to be sophisticated labor; yet, it only takes a few minutes to have your automobile react to the key fob once more.

4. The Ignition Cylinder Is Broken

Your key fob not only serves to open your car door, but it also serves to start your vehicle when it is used in conjunction with the ignition.

Every function that is present in it has a similar function in the automobile that is receiving the requests.

If any of the components are damaged, your key fob will not function.

If you can open the door to your vehicle but are unable to start the vehicle, the problem does not appear to be related to the key fob.

Instead, the ignition may be at fault.

When your car is driven for an extended period, every moving part is subject to wear and strain.

Because of this, the engine will inevitably fail, and your ignition cylinder will also feel the strain, especially if your vehicle is several years old.

Again, whether the problem is with the key fob or the ignition, both automotive locksmiths and mechanics at dealerships are capable of recognizing the problem.

They can advise you on the repair; if the damage is still in its early stages, they may be able to save it through restoration.

If the condition of the ignition cylinder becomes worse, you may be required to replace it.

5. Car Keys That Aren’t The Originals

Although aftermarket auto parts can be more expensive, most people prefer them to those sold by a dealership that is made by the car’s original manufacturer (OEM).

This is due to the significantly lower cost of aftermarket vehicle parts.

In contrast to the $50-$75 pricing of the key fob at an aftermarket auto parts store, the Nissan dealership charges $150-$200 for the same item.

While the latter is preferable to the two options, the former may either work for your car or may require some modifications to be compatible with it.

To make an informed decision about whether or not to use aftermarket components, you must first understand the hazards involved.

Similarly, before utilizing an alternative key fob, be sure it is programmed to operate with your car.

If you neglect this step, your car’s performance may suffer.

This is because they would be not built, especially for anyone brand.

As a result, pairing with your car will necessitate additional programming.

Mechanics and vehicle locksmiths alike should be able to handle this task with ease.

6. Car Key Duplicate

Having a second set of keys to your house or locker isn’t necessarily a bad thing.

Duplicate key fobs are also in demand, which is unsurprising given the current situation.

No one wants to be locked out of their vehicle in the dead of the night while searching for their key fob.

There is peace of mind in knowing that you have extra keys, and also the ability to share them with loved ones.

However, when it comes to key fobs, what most people do not realize is that with each replica, the key fob becomes further distant from the original.

Every key that is replicated has an impact on the integrity of the original.

In layman’s terms, a copy of the original may be sufficient for your needs.

A duplicate of the duplicate, on the other hand, does not work the same way as the original.

In other words, if your key fob isn’t working, it’s probably because it’s as far away and unique from the original as it possibly can be.

Instead of duplicating your key fob, it is preferable to purchase a new one that has been programmed to operate with your vehicle.

Resetting Your Nissan Key Fob After A Battery Replacement

If you’ve recently changed your car’s battery, you’ll need to re-program or reboot your Nissan key fob.

Even though this may not happen regularly, it does occasionally.

Is there a procedure to follow if this happens and I need to re-program my Nissan remote control?

You can also have a locksmith or a dealer configure your key fob for you.

This is the most secure option.

However, you can try to do it yourself if you follow the steps provided in this article.

  1. Enter your Nissan vehicle and use the Lock Switch located on the driver’s side door to secure all of the doors in your vehicle.
  2. Remove the key from the ignition and place it in the ignition again. 6 times in exactly 10 seconds is the time limit for this challenge. Make certain that it has been completely removed from the ignition before re-installing it in the vehicle. Turning the key will not help.
  3. Your first step into the programming process is taken here. The outside and interior lights will both flash twice if this is accomplished properly.
  4. Insert the key into the ignition once more and start the engine to the Accessories mode after entering the programming mode has been completed.
  5. Only one time should you hit any key on the key fob. Try it only once and don’t do it again.
  6. Assuming everything has gone smoothly up to this point, the key fob should be being programmed. Once this was confirmed, the hazard lights would flash.
  7. Removing the key fob from its holder and exiting the car are all recommended steps.
  8. Attempt to unlock the door by using the key fob after it is locked.

Make another attempt if any of the previous steps don’t work.

Make sure to contact the Nissan dealership if you’ve made multiple unsuccessful attempts to fix the problem.
