2011 Hyundai Elantra Key Replacement

The 2011–2016 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.

2011 Hyundai Elantra: key facts

Key type: Mechanical (no chip)
Push-to-start: No
Transponder chip: ID46 (PCF7936/PCF7952) on immobilizer-equipped trims
Programming: NONE
All keys lost: We can originate new keys on site

On Hyundai's official anti-theft software-update list (2011-2022 Elantra): base turn-key trims shipped with NO immobilizer, so any properly cut metal copy starts the car. Limited/push-button trims do carry an ID46 smart-key immobilizer and program via OBD. We confirm trim on the vehicle.

What kind of key does a 2011 Elantra use?

The 2011 Elantra is a mechanical-key car. The key is a metal blade you turn in the ignition. There is no push-to-start on the standard setup, and the car has a mechanical backup key, so there is always a physical key that works the door and the ignition.

The part that matters is the trim. Hyundai's own anti-theft software-update list covers the 2011 through 2022 Elantra, and the reason is simple: base turn-key trims shipped with no factory immobilizer. On those cars there is no chip to match. Any properly cut metal copy will start the engine. Limited and push-button trims are different. They carry an ID46 smart-key immobilizer, and those keys are programmed to the car through the OBD port.

Our data lists the chip family as ID46 (PCF7936/PCF7952) on immobilizer-equipped trims, and that is cross-referenced against two key-supply sources. What it can't tell us from a web page is which of those two situations your particular car is in. We check that on the vehicle itself.

Duplicate key or all keys lost: how does it work on this car?

Both jobs are possible on a 2011 Elantra. A duplicate needs an original key to copy from. If you have no key at all, an all-keys-lost replacement is still possible, and we can do it without towing in most cases, because we come to you with a mobile van or you can bring the car to our Westwood storefront at 10740 Wilshire Blvd.

The programming data for this year shows no special dealer-only procedure and no NASTF secure-data requirement, so you don't have to go through a dealership to get a working key.

Call (213) 577-1366 and tell us the trim if you know it, plus whether you have any working key.
We confirm the car belongs to you by checking your ID against the registration or title, then look at the ignition and dash to identify the trim.
On a base turn-key trim, we cut a key to the lock, test it in the door and ignition, and make sure it turns smoothly.
On a Limited or push-button trim, we cut the key and program the ID46 immobilizer through the OBD port so the car recognizes it.
We test every key we've made before we hand them over, and we suggest cutting a spare while we are there.

What affects the price of a 2011 Elantra key?

We don't quote numbers on a web page, because the honest answer depends on a few things we can only see in person or learn on the phone:

Trim: a plain metal key for a turn-key trim is a simpler job than an ID46 key that has to be programmed.
Lost or spare: copying from a working original is usually the more economical route, while all keys lost involves more work at the car.
Ignition condition: if the lock cylinder is worn or damaged, a new key alone won't fix the problem.
How many keys: cutting a second key during the same visit is generally lighter in cost than calling us back later.
Location and time: a mobile visit to your address and a late-night call are different from walking into the storefront during the day.

Ignition damage and the Kia Boys theft wave

The Elantra's missing immobilizer on base trims has a history. These model years were primary targets of the 2021 to 2023 'Kia Boys' theft wave, because a thief did not need a chip-matched key to start the car. If you've had an attempted theft, or you bought a used Elantra that has a loose steering column cover or a stiff ignition, you may be dealing with more than a lost key.

Ignition lock cylinders and steering columns damaged in theft attempts often need a lock rebuild or replacement, not just a new key. We look at the cylinder first. If it's damaged, we tell you what needs fixing before we sell you a key that may not turn.

Hyundai also offers a free anti-theft software update for this car at hyundaiantitheft.com. We recommend it alongside any key work, and we'd rather you do it than skip it.

What we confirm in person, and why call us

Our data for this year is verified, but the trim question is the one thing we always settle on the vehicle, by VIN and by inspecting the car. The note on this model is clear that base turn-key trims have no immobilizer and Limited or push-button trims do, so we don't guess from the year alone. If anything about your car doesn't match what's described here, we'll say so before we start work.

Wilshire Lock & Key has been in business since 1987, with a Westwood storefront and mobile vans serving 140 cities across Los Angeles and Ventura counties. You reach us directly, not a dispatch middleman, and David oversees the work as owner and lead technician. The phone is answered 24 hours a day, every day of the year.

California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for their license number before work begins. For more on Hyundai keys, see our Hyundai key page or the general Elantra key guide. You can also contact us or return to our home page.

Frequently asked questions

Does a 2011 Hyundai Elantra have a transponder chip?

It depends on the trim. Base turn-key trims shipped with no factory immobilizer, so there is no chip to program. Limited and push-button trims carry an ID46 immobilizer. We confirm which one you have on the vehicle.

Can you make a 2011 Elantra key if I lost all of them?

Yes. All-keys-lost replacement is possible on this year. We verify ownership, identify the trim, cut the key, and program it if your car has the ID46 immobilizer.

Do I need a dealership for a 2011 Elantra key?

No. The data for this year shows no dealer-only requirement and no NASTF secure-data requirement. We handle the cutting and programming ourselves, at our storefront or at your location.

Will a copied metal key start my 2011 Elantra?

On base turn-key trims with no immobilizer, yes, a properly cut metal copy starts the car. On immobilizer-equipped trims, a plain copy will turn the lock but won't start the engine until it is programmed.

My ignition is damaged after a theft attempt. Is a new key enough?

Often not. Cylinders and steering columns damaged in theft attempts commonly need a lock rebuild or replacement. We inspect the ignition first and tell you what the car needs.

What is the Hyundai anti-theft software update?

It is a free update from Hyundai for 2011 to 2022 Elantras, available at hyundaiantitheft.com. We recommend it alongside any key work, especially on trims without a factory immobilizer.

We cover all these cities
