Kia Key Fobs — Everything You Need to Know

Kia key fobs are something from the future. Who knew we’d be accessing our vehicles remotely in 2021?

However, with these technological advances comes confusion. We’re here to clear things up with our free advice!

Read on to learn more about Kia key fobs, where you can get them, how to replace them, the average price, and more.

What Is a Kia Key Fob?

Unlike normal Kia keys, Kia fobs contain RFID chips that emit radio frequencies. These frequencies allow you to operate vehicles on your terms.

Functions

The remote can perform several functions for Kia vehicles, some of which include:

  • Locking/unlocking the doors
  • Rolling down the windows
  • Popping the trunk
  • Setting off the alarm
  • Starting vehicles

 

To ensure your Kia key works, you must program it for your vehicle. We’ll go over that process later. For now, understand there are different Kia key fob styles depending on the make/model/year of vehicles.

Do I Need a New Kia Key Fob?

In some cases, it’s obvious when a customer needs a fob replacement. For instance, you might’ve lost your current remote or want to get an extra one for a family member or friend to grant them privacy.

In other cases, however, you might question whether you need a replacement.

Replace the Battery

Drivers may notice that their Kia key fob doesn’t work at all or needs to be closer to the vehicle to register. If you’re experiencing this problem, try battery replacement first. It will be cheaper and easier than replacing the whole key fob.

To replace the battery, open and close the battery component yourself.

If you don’t have the right battery on hand, login to your Amazon account and order one.

Bring Your Kia Fob to a Shop

Not sure how to do it? Bring your key fob to a local automotive shop. They might do the replacement for free when you buy the battery there. If not, you can pay for the service. (Pro tip: Consider having them show you how to open and close the battery component. That way, you can save yourself a visit in the future).

If your Kia key fob is still not working well after you replace the battery, it’s a sign that you require a new Kia remote.

What Are the Different Types of Kia Key Fobs?

When you login to your computer and search online, you can agree that there are many types of Kia fobs.

Some Kia keys require you to open/close the doors by pushing buttons. Others can open/close vehicles while remaining in your pocket. Kia keys also work differently when it comes time to start your vehicle. With some, you’ll need to insert the device into an ignition slot. Others have push-to-start capabilities that only require the key to be inside your vehicle.

Can I Buy a Kia Key Fob and Program It Myself?

If you’re a customer who wants to save some time, you’ll contact your automotive dealer. They can match you with compatible Kia keys and offer their programming service today.

But what if you’re more of a DIY customer who wants a lower price? Lucky for you, you can search for a 2021 Kia key fob and complete the programming yourself.

Where Can I Get a Replacement Kia Key Fob?

You have two options for getting a new Kia key fob:

Call Your Kia Dealer

If you want to go the old-fashioned way, call your car dealer. The team can see if they have compatible remotes in stock. If they do, you’ll have to head down there and choose one.

But while you’re still on the phone, use the time to ask questions and get more information. Ask what the price is, whether there are recalls on your current remote, what the replacement process is like, etc.

Once you’re at the dealer, they will program the remote for you within the same day. So, if you require a remote today, the higher price may be worth the convenience.

Shop Online

Don’t want to head to your Kia dealer? Consider shopping online! There are tons of quality retailers that provide remotes at better sales. Just use the filters to look through the remotes for different vehicles.

As long as you view products from a reputable site, you should find the perfect remote. And if you want help, don’t worry — all of the “Call Us!” requests on these sites prove they’re willing to help.

How Much Is a Kia Key Fob Replacement?

Now for the question that dictates most of our lives — what’s the price? Replacements can range anywhere from $50 to $400, depending on what model you have and where you go. Going to a car dealer, for instance, will almost always be more expensive. The higher price is because they prioritize sales and bill you for the programming service.

If you’re on a budget and don’t want to sit at your dealer for hours, you should go the DIY route. Most people agree that shopping online will give you access to better sales and save you the price of a programming service.

When you look online, however, be wary of exceptionally affordable keys. Dirt-cheap remotes should set off an alarm and indicate that the seller may not be reputable. Don’t ignore this alarm — contact a more credible seller instead.

How Do I Program My Kia Key Fob?

If you buy a Kia key fob, you could call a dealer and ask for their programming service. But that kind of defeats the whole DIY ideology — hence, you probably want to do it yourself. We can’t give you specific instructions, as a 2021 Sportage may use a different method than a 2021 Soul.

However, the online seller you buy from should provide you with a how-to guide. If not, contact their team and ask! You can also search for and view specific guides online.

How Long Will It Take?

The programming process can involve everything from clicking buttons to listening for the alarm. In any case, a job well done won’t take hours. Most drivers have their key up and running within minutes.

Kia Key Fob — The Bottom Line

Getting a new Kia key fob isn’t as hard as some people make it out to be. All you have to do is phone your dealer today. Or, find a model online, order it, and program it yourself following the seller’s instructions. If you need help, don’t be afraid to take them up on their “Call Us!” phone offers.
