2023 Hyundai Kona Key Replacement

2023 Hyundai Kona: key facts

Key type: Transponder chip key
Push-to-start: No
Transponder chip: ID47 (Hitag 3)
Programming: OBD
All keys lost: We can originate new keys on site

Last OS year; immobilizer standard from November 2021 production. Smart-key trims use ID47 fobs (listings cover 2021-2023); the base bladed key's chip is not separately catalogued — identified on the car.

What kind of key does a 2023 Kona use?

The key on file for the 2023 Kona is a transponder key with an ID47 (Hitag 3) chip, and that chip family is verified against two separate parts catalogs. The key also has a mechanical blade, so it is a physical key that turns in the ignition, not a push-button setup. The car's immobilizer reads the chip when you turn the key. If the chip isn't recognized, the engine won't start, even when the blade turns the ignition freely.

This is the last model year of its run, and the immobilizer was standard from November 2021 production onward. So a 2023 Kona is firmly in the era where a blade-only copy is not enough.

In practice, that means two things for you. First, the blade and the chip are two separate jobs, and both have to be right. Second, the programming happens through the car's OBD port, and the data we work from does not list NASTF SDRM access as a requirement for this year. That keeps the job simpler than on many makes where a dealer is the only route.

Spare key or all keys lost: how the job differs

For this setup, duplicating a key requires an original key to work from. If you still have one, adding a spare is the more straightforward job, and it is also the best time to do it. Having a second key made before you need one is almost always the lighter-cost path compared with an emergency.

If every key is gone, that is still possible to solve. The data for this year confirms an all-keys-lost job can be done. It simply takes more steps, because the car has to accept a new key without an existing one to reference.

You call (213) 577-1366 and we confirm the year, trim and VIN, and whether you have any working key at all.
We identify the key you need. On the base bladed key, the chip is identified on the car itself rather than assumed.
We cut the blade to the car's ignition and doors, whether from an existing key or from the lock and VIN information.
We program the ID47 chip through the OBD port and check that the new key starts the engine.
We test every key you have, including the old one, so you know all of them work before we leave.

What goes wrong with 2023 Kona keys

The problems we see listed for this key setup are specific, and most are avoidable:

Hardware-store copies cut without a chip. They often open the doors, but they will not start an immobilizer-equipped car. This is the most common disappointment.
Low-quality cloned or aftermarket chips that fail intermittently. The key works for a while, then stops starting the car with no warning. If a cheap copy behaves this way, replacing the chip properly is the fix.
Worn ignition wafers on high-mileage cars. If your key feels loose or catches in the ignition, the lock itself may be the problem, not the key. We look at both before recommending anything.
Smart-key trims: a dead fob battery shows 'key not detected'. Try a fresh battery before assuming the fob has failed.

What affects the cost of a 2023 Kona key?

We don't quote numbers on a web page, because the honest answer depends on a few real variables:

Whether you have an original key to copy, or all keys are lost. An all-keys-lost job involves more work.
Which key your car actually has: the bladed transponder key or a smart-key fob. They are different parts.
How many keys you need programmed in one visit.
Whether the ignition or the blade's fit needs attention, for example if wear is part of the problem.
Where the car is and what time you call. We run mobile vans as well as our Westwood storefront, and after-hours calls are answered at any time of day.
Cheaper-looking copies that skip the chip or use a poor-quality chip tend to cost more in the end, since you pay for the job twice.

What we confirm by VIN, and who you'd be calling

Here is the one thing our data does not settle. Smart-key trims use ID47 fobs, and the listings we have cover 2021 through 2023. The plain bladed key's chip, though, is not separately catalogued. So we don't guess: we confirm which key your Kona has by VIN and by looking at the car, before ordering or cutting anything.

You'd be dealing with Wilshire Lock & Key, in business since 1987, with a storefront at 10740 Wilshire Blvd in Westwood and mobile vans serving 140 cities across Los Angeles and Ventura counties. It is one company, with no dispatch middleman, and David oversees the work. California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for that number before work begins.

Frequently asked questions

Can you make a copy of my 2023 Kona key if I only have one?

Yes. Duplication on this setup needs an original key to work from, and you have one. We cut the blade and program a new ID47 chip. Do it before the last key is lost.

What if I've lost every key to my 2023 Kona?

An all-keys-lost job is possible for this year. It takes more steps than a simple copy, and we confirm the exact key by VIN first. Call (213) 577-1366 and we'll talk you through what we need.

Does a 2023 Kona have push-to-start?

The key setup on file for this year is a transponder key with a mechanical blade, not push-to-start. Smart-key trims do exist, though, and they use ID47 fobs. We confirm by VIN which one your car has.

Why won't my hardware-store key start the car?

Most likely it was cut without a programmed chip. The blade can open the doors, but the immobilizer needs to recognize an ID47 chip before the engine will run. The key has to be programmed to the car.

My smart fob says 'key not detected.' Is it broken?

Often it's only the fob battery. On smart-key trims a dead battery produces that message. Replace the battery first. If the message stays, call us and we'll check the fob itself.

Can you come to me, or do I need to bring the car in?

We run mobile vans and also have a storefront at 10740 Wilshire Blvd in Westwood. Programming goes through the OBD port, so we can often work where the car is parked. Call to confirm for your location.

What should I ask a locksmith before hiring them?

Ask for their California BSIS LCO license number, since the state requires locksmith companies to hold one. Also ask whether the key will include a programmed chip, and who will actually come to the car.

We cover all these cities
