2017 Hyundai Elantra Key Replacement in Los Angeles

The 2017–2020 Elantra uses the same key setup, so everything on this page applies to those years too. The full picture is on the Hyundai Elantra key guide.

2017 Hyundai Elantra: key facts

Key type: Mechanical (no chip)
Push-to-start: No
Transponder chip: None
Programming: NONE
All keys lost: We can originate new keys on site

Still on Hyundai's anti-theft update list: base turn-key trims have no immobilizer (a 2020-era installer forum confirms US cars have no chip unless push-to-start). Smart-key trims are listed by some catalogs as Texas DST-AES '8A' and by others as Hitag-3 ID47 — we identify the chip on the vehicle. Equipped trims program via OBD.

What kind of key does a 2017 Elantra use?

The 2017 Elantra is a mechanical-key car. It has a metal blade key you turn in the ignition, and it is not a push-to-start setup. There is also a mechanical backup key on the car, so the cut of the key is a real part of how this vehicle works.

Here is the part owners often do not expect. On the base turn-key trims, there is no factory immobilizer. That means no chip has to be matched to the car. A plain metal copy cut to the right pattern will start it. That makes a replacement simpler and usually the more economical route compared with a chipped key, but it also tells you something about how easy the car is to steal, which we get to below.

Trims with a smart key are a different story. Catalogs disagree on the chip there. Some list a Texas DST-AES chip (often called 8A), and others list a Hitag-3 ID47. We do not guess between them. We identify the chip on your vehicle before we order or cut anything. Trims that do carry a chip are programmed through the OBD port.

Duplicate key or all keys lost: how each works on this car

Both situations are possible on a 2017 Elantra. The difference is mostly in how much work sits between you and a key that starts the car.

Duplicate: you hand us a working key and we copy it. An original key is needed for this route, and it is the lighter-cost path because there is less to figure out.
All keys lost: we can still make you a key. On a base turn-key trim that is mostly a matter of cutting a key that fits your lock. On a chipped trim, the new key also has to be programmed to the car through the OBD port.
Programming on this model does not require NASTF/SDRM credentials, so there is no extra gate to get through before we can start.

Damaged ignitions and the anti-theft update

This is where the 2017 Elantra needs a more honest conversation than most cars. Base turn-key trims of these years were primary targets in the 2021 to 2023 theft wave often called the Kia Boys trend. Because there is no immobilizer, thieves did not need the right key, only a way to turn the ignition.

The result we see is damage to ignition lock cylinders and steering columns. If your Elantra was broken into or nearly stolen, a new key alone may not fix it. A worn or forced cylinder can mean a lock rebuild or a replacement, and then the key has to match the new cylinder. We look at the cylinder first so you do not pay for a key that will not turn.

Your car is also eligible for Hyundai's free anti-theft software update, available at hyundaiantitheft.com. We recommend it alongside any key work. Software is the fix that addresses the missing immobilizer problem, and a new key does not.

What affects the price of a 2017 Elantra key?

We do not quote numbers on a web page, because the same model can need very different work. These are the things that move the cost:

Trim: a base turn-key car with a plain metal key is a different job from a smart-key trim with a chip.
Whether you have a working key to copy, or all keys are lost.
Whether the ignition cylinder or column is damaged and needs a rebuild or replacement.
Whether we come to you with a mobile van or you come to our Westwood storefront at 10740 Wilshire Blvd.
Time of day, since we answer around the clock and night work is handled differently from a daytime appointment.

What we have not verified, and how we handle it

The chip data for the smart-key trims on this year is conflicting. A single source (transpondery.com) is what we have, and catalogs split between DST-AES 8A and ID47. We have not verified it, so we confirm by VIN and by looking at the car in person before we commit to a key blank. If you call, have the VIN ready; it is on the dashboard by the windshield and on the driver's door jamb.

Wilshire Lock & Key has been in business since 1987, with a storefront and mobile vans, and David oversees the work. When you call, you reach our own company rather than a dispatch middleman. For other years and trims, see our Elantra key pages or the wider Hyundai key guide. If you would rather send us the details first, use the contact page.

Frequently asked questions

Does a 2017 Elantra have a transponder chip?

It depends on the trim. Base turn-key trims have no factory immobilizer, so a plain metal key starts the car. Smart-key trims are listed with a DST-AES (8A) chip by some catalogs and an ID47 by others, so we identify the chip on the vehicle.

Can you make a 2017 Elantra key if I lost every key?

Yes. All keys lost is possible on this car. On a chipped trim the new key is programmed through the OBD port. On a base turn-key trim the work is mostly cutting a key to fit the lock.

Do I need my original key to get a copy?

For a straight duplicate, yes, a working original is needed. Without one, we treat it as an all-keys-lost job.

Why does my Elantra need a lock repair and not just a key?

If someone tried to steal the car, the ignition lock cylinder or steering column may be damaged. In that case a new key may not turn the lock, and the cylinder may need a rebuild or replacement first.

Should I get the Hyundai anti-theft software update?

Yes, we recommend it. Your car is eligible for the free update at hyundaiantitheft.com, and it addresses the missing immobilizer on base trims, which a new key does not.

Is dealer-only work required for this key?

Not according to our data. Programming on this model does not require NASTF/SDRM credentials, and we handle both cutting and OBD programming ourselves.

What should I ask any locksmith before they work on my car?

Ask for their California BSIS locksmith company (LCO) license number. California requires locksmith companies to hold one, and a legitimate company will give it to you without hesitation.
