Hyundai keys start with one question: is there an immobilizer in this car?
4Keys Locksmith, a Georgia LLC on the Secretary of State's register, is a mobile Hyundai locksmith in Metro Atlanta, GA that holds ALOA training and NASTF VSP authorization and is insured by The Hartford, with technicians dispatched from Brookhaven 24 hours a day. The vans carry the key machine and the programmers to the Hyundai, since 4Keys has no shop for it to be towed to; how a mobile locksmith works covers the rest.
A Hyundai key is never chosen from the model year alone. Hyundai built certain turn-key Sonatas, Elantras, Santa Fes and Genesis Coupes without an engine immobilizer, and the same badge and year can come either way, so the answer decides whether the job is a mechanical key and a remote or a chip key taught to the car with its PIN. That system, SMARTRA, is explained below and shared with Kia, whose bulletins and cylinder protector live on the Kia locksmith page.
Hyundai work here covers keys for modern smart-key models, a fob bought from an online seller and programmed after its FCC ID, frequency and part number are matched to the car, and a brand-new warranted fob in place of one that has failed. PIN access goes through NASTF VSP, which also covers the dealer-level software 4Keys uses (the dealer-level tools a locksmith can use), and companies with Elantras or Santa Fes in service can key them together through fleet key programming. You get the price by phone before dispatch; published rates are listed at 4Keys pricing.
On a push-button Hyundai the smart key is the remote and the transponder in one case, so a new one is taught to the car electronically, and the emergency blade inside it is cut to match the door lock. That is what keys for modern cars means in practice: a key the car has to accept, made at the curb with PIN access reached under NASTF VSP. Tell the dispatcher whether you hold a smart key or a flip key, because the two are separate jobs and are quoted separately.

The Hyundai immobilizer, explained: SMARTRA, the six-digit PIN and the cars built without one
Hyundai's immobilizer, in the generation its service manual documents, is built around a unit called SMARTRA. Hyundai's service manual for the 2006-2010 Elantra describes the sequence, and the same system description applies to that era: when the first key is taught, the SMARTRA registers itself with the engine computer (PCM) at the same moment, and from then on the engine runs only when a taught transponder or smart key answers.
Teaching a key asks for the vehicle's six-digit PIN. Three wrong entries in a row, and the PCM refuses any further teaching for an hour, a lock that exists so nobody can guess their way in. The system holds up to eight keys. 4Keys reaches that PIN through an authorized channel as an NASTF VSP authorized locksmith: NASTF VSP credentials cover key programming and immobilizer codes, and NASTF's free technician access also lists Hyundai, Genesis and Kia software gateway validation. The keys and smart keys it teaches are original (OEM) Hyundai parts.
The other half of the story is the Hyundai with no immobilizer at all. Hyundai's own dealer guidance, filed with NHTSA, lists vehicles "not equipped with immobilizer & not equipped START/STOP ignition button": certain 2011-2014 and 2015-2019 Sonatas, certain Elantras of 2011-2016, 2017-2020 and 2021-2022, certain 2013-2018 Santa Fe and Santa Fe Sport, certain 2019-2022 Santa Fes, and certain 2013-2014 Genesis Coupes. Every entry carries the word certain. The same document gives a rule of thumb: if a Hyundai has a start button, or an immobilizer lamp among its cluster warnings, it has an immobilizer, and for a turn-key car without the lamp, Hyundai's answer is "It depends." Its dealers settle it with an Immobilizer VIN Lookup tool.
Hyundai also states that, from November 2021, every Hyundai it produced had an engine immobilizer as standard, and that vehicles sold by Genesis Motor America come with one as standard. For the earlier turn-key cars on that list, a key has no chip to program: it is a mechanical blade cut to the locks, plus a remote paired to the body. That follows from Hyundai's own definition, in which an immobilizer stops the engine unless the correct transponder or smart key is present.
Eligible cars on that list were offered anti-theft software through Hyundai's Campaign 993. After the update, the fob must disarm the alarm first, or the car will not start, and Hyundai warns that aftermarket alarms or remote starters may not operate normally. For 2011-2022 non-immobilizer vehicles that could not take the software, Hyundai's guidance offered reimbursement for a steering-wheel lock. The practical consequence for a spare: on an updated car, a blade alone is not a complete key, so order it with its own paired remote. Key types follow the start system, with flip remote keys on turn-key cars and proximity smart keys with an emergency blade on push-button cars, and it is the reason the technician, phoning ahead, may want a photo of your current key.
Hyundai models by immobilizer status, as Hyundai lists them
Years and generation codes exactly as Hyundai's dealer guidance and NHTSA print them. Each list says certain vehicles, so the VIN decides your car; if the last key is gone, the year is confirmed with you by phone.
| Hyundai model | Years as listed | Immobilizer and key | Key work at the car |
|---|---|---|---|
| Sonata (YFa) | Certain 2011-2014 | Turn-key builds Hyundai names as having neither an immobilizer nor a start button; flip remote key | VIN read first; blade cut and remote paired, or a chip key taught with the PIN |
| Sonata (LFa) | Certain 2015-2019 | Same Hyundai list for turn-key builds; push-button builds carry a smart key | Spare, all-keys-lost key, smart key programming |
| Elantra (UD/MD) | Certain 2011-2016 | Turn-key builds on the no-immobilizer list | Blade cut by code and remote paired where no chip exists |
| Elantra (AD, CN7) | Certain 2017-2020 (AD) and 2021-2022 (CN7) | Turn-key builds on the same list; any with a start button or immobilizer lamp has one | Spare key, remote pairing, PIN teaching on immobilized cars |
| Santa Fe, Santa Fe Sport | Certain 2013-2018 | Turn-key builds on the no-immobilizer list | VIN check, spare key, remote pairing |
| Santa Fe (TMa) | Certain 2019-2022 | Turn-key builds on the same list | Spare, all-keys-lost key, fob programming |
| Genesis Coupe (BK) | Certain 2013-2014; recall 24V-562 on 2010-2013 | Turn-key builds on the no-immobilizer list; ignition lock switch return spring under recall | Spare key, remote pairing; recall work stays with the dealer |
| Any Hyundai or Genesis with a start button | All years | Push-button start or an immobilizer lamp means an immobilizer, by Hyundai's rule; smart key with emergency blade | Smart key taught to the car with the vehicle PIN |
| Any Hyundai built from November 2021 | From November 2021 | Engine immobilizer standard, per Hyundai | Key or smart key programming under NASTF VSP |
| Updated turn-key Hyundai (Campaign 993) | Eligible 2011-2022 cars | Anti-theft software: the fob disarms the alarm before the start | Spare quoted as blade and paired remote together |

How a Hyundai key job is sorted out, before the van leaves and at the car
Five steps, and the first three happen on the phone.
- 1
Tell the dispatcher how the Hyundai starts
A start button already answers the immobilizer question by Hyundai's rule, and so does an immobilizer warning lamp on the gauges. A turned key without the lamp leaves it open, and the VIN closes it. The VIN is printed on a plate you can read from outside, low on the windshield.
- 2
Say how many keys still work
One working key makes the job a spare. None makes it a key cut by code, plus PIN teaching on an immobilized car. On that call the route for your model year is agreed, and the dispatcher asks for whatever documents the case requires.
- 3
Mention the anti-theft update or an aftermarket starter
If the car went through Hyundai's anti-theft campaign, the new key needs a paired remote to disarm it. An aftermarket alarm or remote starter can behave differently after the update, which is worth saying before the visit.
- 4
Hear the price, then the technician calls back
Before dispatch you hear a price; the rate card lives on the pricing page. On the way, the technician phones and may want a snapshot of your key or of the fob you ordered.
- 5
At the car: cut, pair or teach
The blade is cut, the remote is paired, and on an immobilized car the key is taught to the immobilizer with the PIN, carefully, since a third wrong entry freezes teaching for sixty minutes.

David got my car up and running in less than 5 mins
Technician did an excellent job! Highly recommend your services! In addition I was so surprised by the immediate prompt service, along with his friendly professional attitude! Thank you so much because I really needed a car key asap!
In English or Spanish, for the Hyundai and the house it is parked at
Spanish is a working language at 4Keys: the phone is answered in it, there are Spanish-speaking technicians on staff, and a Hyundai owner who would rather explain the problem in Spanish can do so from the first word. The Spanish pages of the site, such as cerrajero en Atlanta, cover the same services in that language.
The van that keys your Hyundai also works on door locks. At home: lockouts, rekeys after moving in, deadbolts and smart locks, under residential locksmith service and residential locks around Atlanta. At a business: rekeys when keys walk out with former staff, keying systems with masters, access control and panic bar hardware, under commercial locksmith service and commercial locks in Metro Atlanta.
From Brookhaven the vans cover Metro Atlanta, and you hear the arrival time quoted on the phone. The Hyundai can be in a driveway, at the curb, in an apartment lot or a work lot; give the gate code or the building. Pages for some of the neighborhoods on the routes: Grant Park, whose page explains why Hyundai and Kia keys start with the VIN, West End on copying a key before the last one is lost, East Atlanta for a key that turns and will not start, Stonecrest on a locksmith versus the dealer, and Jonesboro. 4Keys is ALOA-trained and keys vehicles of six origins, Korean, Japanese, American, German, British and Italian.
