Call (772) 758-1322 for mobile service. Hyundai uses a transponder-based immobilizer across most models since 2000. Autel IM608 Pro handles Hyundai programming via OBDII with PIN code lookup for 2015+ models. Typical $195-$325 versus $350-$495 at Hyundai dealer.
All models including electric Ioniq line.
Hyundai is a growing brand on Treasure Coast roads. Elantra, Sonata, Tucson, Santa Fe, Kona, and the newer Palisade are all common family vehicles. Hyundai has used various immobilizer generations over the years, with 2015+ models requiring PIN code authorization from the VIN.
For most Hyundai models, programming is done via OBDII with Autel IM608 Pro. The Autel handles Hyundai PIN lookup automatically, making the programming process straightforward. Smart key models (2015+) have additional fob programming that takes 5-15 minutes longer than basic transponder keys.
Treasure Coast Locksmith programs every Hyundai model from 2000 through 2026 including current Ioniq EV models. Typical job runs 30-75 minutes onsite.

Hyundai immobilizer technology
Hyundai's immobilizer system has evolved across several generations. Earlier Hyundais (2000-2008) used simple transponder technology similar to Honda HISS. Mid-generation Hyundais (2009-2014) added stronger encryption and BCM (Body Control Module) integration.
Current Hyundais (2015+) use PIN code authorization via OBDII and require Autel IM608 Pro or equivalent equipment for programming.
Smart key programming for 2015+ Hyundai models includes both the transponder chip (for immobilizer authentication) and the proximity fob (for push-to-start and remote functions). Both have to be programmed in the same session for the smart key to function correctly.
Hyundai-specific quirks: 2016-2019 Tucson has a known intermittent programming issue on some trim levels that requires retry procedures. 2020+ Palisade requires specific smart key variants that we stock. Ioniq 5 and 6 EV models use enhanced security that Hyundai Dealer Diagnostic equipment is sometimes required for, though our Autel IM608 Pro handles most Ioniq programming via OBDII.

Can you program a 2024 Hyundai smart key?
Yes. Current Hyundai models (Elantra, Sonata, Tucson, Santa Fe, Palisade, Kona, Ioniq 5, Ioniq 6) all programmable with Autel IM608 Pro and current firmware. Typical 2024 Hyundai job: 40-75 minutes.
Do you do Hyundai and Kia keys?
Yes, both brands. Hyundai and Kia are sister brands sharing many platforms and immobilizer technologies. Our equipment handles both.
If you have a Hyundai and a Kia in the same household, we can program both during a single visit.
Does Hyundai require PIN code programming?
For 2015+ models, yes. Our Autel IM608 Pro retrieves the PIN from the Hyundai database using your VIN. You don't provide the PIN - we get it automatically.
For older Hyundais (pre-2015), PIN is not required.
Can you program Hyundai Ioniq EV keys?
Yes. Ioniq 5, Ioniq 6, and Kona Electric use enhanced security but are within our standard Hyundai programming scope. Our Autel IM608 Pro handles Ioniq programming with current firmware.
Typical Ioniq job: 45-75 minutes.
How long does Hyundai programming take?
Transponder with working key: 20-35 minutes. All-keys-lost transponder: 35-55 minutes. Smart key with working key: 30-50 minutes.
All-keys-lost smart key: 45-75 minutes. Total appointment 75-120 minutes.
Can you clone a Hyundai key?
For older Hyundais (2000-2010), sometimes yes. For 2011+ models with encrypted systems, cloning is not possible - full programming required. We verify chip type during phone consultation.
Does Hyundai key programming require dealer tools?
No. Our Autel IM608 Pro is aftermarket equipment that handles Hyundai programming without needing Hyundai Dealer Diagnostic Computer (GDS/KDS). We program 2000-2026 Hyundai models routinely without dealer involvement.
What about Hyundai Genesis?
Yes. Genesis is Hyundai's luxury brand and uses similar programming to other Hyundais. Genesis G70, G80, G90, GV70, GV80 all programmable with Autel IM608 Pro.
Typical Genesis job: 45-75 minutes.
Do you program Hyundai work vehicle keys?
Yes. Hyundai commercial vehicles and fleet vehicles use the same immobilizer as passenger cars. For fleet key programming with multiple keys per vehicle, we offer bulk discounts.
Can you program Hyundai keys at my location?
Yes. Mobile service is our standard. We come to your Hyundai wherever it's parked - home, office, parking lot.
We need VIN access and OBDII port access, both standard on every Hyundai.
Is Hyundai programming harder than Honda or Toyota?
Similar complexity to Honda, easier than Toyota H-chip. Hyundai PIN-based programming is straightforward with the right equipment. Typical programming times are comparable to Honda HISS and faster than Toyota H-chip.
