Hyundai is one of the fastest growing car makers in the US market. Their cars are easy on the wallet, come with a great standard warranty, and can even be fun to drive! My wife owns one of the newer Kona models, and we both just love the little car!

But what can your Hyundai key fob do? And what if you need extra or replacement Hyundai remotes? How do you know which one to pick? Is it by car or by year? Help! Is anyone there!? Please show me a sign!

Before sending your dealership a panicked email, take a deep breath, our enthusiastic customer. You’ve come to the right place. By the end of this guide, you’ll want to call us for future fob info instead.

When shopping around for new remotes, view this quality guide for our expert advice. We’ll cover the price of remotes, what your car requires, and what you should do before sending for a replacement.

Key Fob Remote Types

A replacement Hyundai key fob will vary depending on your car model. Refer to our handy site guide about Hyundai keyless entry. Below are the most popular Hyundai cars and the options you’ll have for replacement.

Black Hyundai Suv

Turn-in-Key Ignition Hyundai Fobs

Specific Hyundai keyless entry fobs are equipped with a standard ignition, meaning your vehicle requires a physical blade to start.

Standard Features:

  • Lock/unlock buttons
  • Panic alarm
  • Trunk release (select models)

Turn-in-Key Hyundai Key Fob Remotes:

  • Flip Key
  • 3-Button Grey Hatch

  • 4-Button Leather Strap

When needing a new one, the price is generally less than replacing a smart key (but it’s still not cheap).

Currently, flip remotes and 3-button grey hatch are the styles for current vehicles.

But don’t worry, dear customer! That doesn’t mean you can’t find a quality key fob replacement for older Hyundai cars.

Before You Select A Replacement

If you’re shopping around for Hyundai remotes outside your dealer, it’s still a good idea to contact them to confirm you’re shipping the correct remote.

Specific Hyundai models, like the 19-21 Hyundai Ioniq, have two remote options. Your dealer can show you the correct part number so you can ensure you get the fob you need.

If the price of replacing your remotes is too steep, then you can easily change the battery at home. Buy a battery at a fraction of the price of a fob and have it sent to your home via free shipping.

Programming Your Hyundai Key Fobs

Pairing your Hyundai keyless entry fob with your car is not something you can do at home.

Programming replacement remotes for this particular car will require a professional. Your local dealership will offer this service, but the cost can be high. To potentially get a better deal, head to Google and perform pricing comparisons with a locally-based automotive locksmith.

Frequently Asked Questions

How much is a new key fob for Hyundai?

The cost will depend on the source, but you can expect to pay anywhere between $150 and $600. This will depend on the car model and the type of Hyundai key you need.

You can potentially source a remote from a third-party seller at a reduced rate. Try to find someone with free shipping, too!

How much is a Hyundai smart key?

Smart keys are programmed with an electronic code, which opens car doors and starts your engine. You can expect to pay a pretty penny on a replacement because of the advanced Hyundai key fob tech.

The price for replacement Hyundai smart keys range between $220-$500, depending on your car and the year it was made. You could contact a third-party seller to see if they beat dealer replacement pricing. Bonus points if the seller’s site offers free shipping.

If you find something for dirt cheap, be wary of its abilities.

Can I program my own Hyundai key fob?

A Hyundai key fob remote requires special machinery for programming. Unfortunately, you can’t do it at home. Only a dealer or automotive locksmith can program remotes for you.

You could have to pay your Hyundai car dealer to program your fob. This service can cost between $50-$100, depending on your dealership.

Some may program your replacement Hyundai key fob for free if you were a previous customer. It’s worth sending your dealer an email to ask.

For a possibly better price, you could find a local automotive locksmith via Google. When you view their web page, make sure they offer the service you need. If you’re unsure, contact them to ask! You don’t want to select a place that can’t program a Hyundai remote.

What battery should I use?

The good thing about Hyundai fobs is they all require the same battery: the CR2032.

Does replacing the remote’s battery require programming?

You’ll have to become a customer of a dealer or locksmith, though, as battery replacement still requires programming. But at least the overall price you’ll pay is way down.

Why are key fobs so expensive?

Unlike the old days, car remotes are costly to replace because of the advanced technology required to manufacture remotes. Keys for most vehicle models built after 1995 now have to be explicitly programmed for your vehicle.
