Hyundai Key Replacement, Key Fob Programming & Smart Key Service
From PINHA-T036 transponder keys to TQ8-FOB-4F30 smart proximity fobs, we cut and program Hyundai keys at your location across Palm Beach County.
Hyundai keys moved through several systems shared with the corporate sibling Kia, from early transponder keys (FCC PINHA-T036) through flip keys to today's push-to-start smart proximity fobs. The chip and fob changed with each generation, so the year and ignition type decide which key your Hyundai needs.
Our mobile techs carry the blanks and programming tools for the Hyundai lineup most common in Palm Beach County, including the Elantra, Tucson, and Santa Fe. Whether you have lost every key or simply want a spare, we confirm whether your Hyundai is turn-key or push-to-start before we cut, and we tell you the price before we start.
Hyundai models we service
Hyundai key types by generation
Hyundai keys changed significantly from one era to the next. The right blank, chip, and programming path depend on the year, trim, and ignition type, which is why we ask for the details before selecting a key.
2006 to 2012: transponder keys
Hyundai used transponder keys (FCC PINHA-T036) that engage the immobilizer. A blade that fits the lock still will not start the engine unless the chip is programmed to the car.
2013 to 2019: flip keys and early smart keys
Flip and remote keys (FCC NYOSEKSAM11ATX) appeared alongside the first push-to-start smart keys (FCC SY5HMFNA04) on higher trims. Confirming the trim matters because the fob and programming path differ between turn-key and proximity.
2020 to present: smart proximity fobs
Current Hyundais use push-to-start smart proximity fobs (FCC TQ8-FOB-4F30, with the TQ8-FOB-4F31 variant on some Tucson trims) with an emergency blade inside. Lost proximity fobs are programmed to the specific vehicle.
Hyundai key data by model
Verified blank, chip, and FCC references are marked accordingly. Where a value depends on trim, button count, or production date, confirm it from the original key, a VIN lookup, or a supplier catalog before cutting or ordering.
Data is drawn from professional locksmith key references. It is a starting point for identification, not a guarantee for your specific vehicle.
Hyundai Elantra Key Replacement
The Elantra spans transponder keys, flip keys, and modern push-to-start smart fobs depending on the year and trim, so the ignition type determines the key.

Hyundai Santa Fe Key Replacement
The Santa Fe follows the Hyundai key progression, but the exact fob varies by year and trim, so we confirm the precise key from the original or the VIN before cutting.
| Year range | Key type | Ilco / keyway | Chip / system | FCC / OEM | Programming | Emergency / service key | Source confidence |
|---|---|---|---|---|---|---|---|
| 2007-2012 | Transponder blade key | Transponder key blank | Immobilizer transponder | FCC PINHA-T036 | OBD programming | Service key | Verified from source data |

- •Santa Fe trims and model years carry several different fobs, so we confirm the exact key by the VIN or your original before we order.
Hyundai Sonata Key Replacement
The Sonata moved from transponder and flip keys to push-to-start smart fobs on higher trims, so the year and ignition type decide the key and emergency blade.
| Year range | Key type | Ilco / keyway | Chip / system | FCC / OEM | Programming | Emergency / service key | Source confidence |
|---|---|---|---|---|---|---|---|
| 2011-2014 | Transponder / flip key by trim | Flip key blade | Immobilizer transponder | Confirm FCC from original key or VIN | OBD programming | Service key | Confirm with original fob |

- •Sonata trims mix flip keys and smart fobs in the same years, so tell us whether you twist a key or press a button to start.
Hyundai Palisade Key Replacement
The Palisade is push-to-start across its run and uses smart proximity fobs, with more than one fob style by trim, so we match the exact key by the original or the VIN.
| Year range | Key type | Ilco / keyway | Chip / system | FCC / OEM | Programming | Emergency / service key | Source confidence |
|---|---|---|---|---|---|---|---|
| 2020-2025 | Smart key (proximity, push-to-start) | Emergency blade inside fob | Smart-key immobilizer | Confirm FCC from original fob or VIN | Proximity programming | Emergency insert | Needs VIN confirmation |
- •Higher Palisade trims can carry a different smart fob, so have the original handy or the VIN ready so we order the right one.
Common Hyundai key problems
- •Worn transponder blades that turn the lock but no longer reliably start the engine.
- •Lost or water-damaged smart proximity fobs after a day at the beach or on the boat.
- •Dead smart-key coin batteries mistaken for a failed fob.
- •All-keys-lost situations on push-to-start models that require programming to the vehicle.
- •Flip keys where the buttons stop working but the blade still turns the lock.
Hyundai programming notes
- •Adding a spare while you still have a working key is faster and cheaper than an all-keys-lost job.
- •Smart proximity fobs are programmed to one specific Hyundai and cannot be reused on another vehicle.
- •Hyundai and Kia share corporate key systems, but we still confirm the exact fob by the VIN before we order.
- •A no-start with a good battery is often the chip or immobilizer, not the engine, and the key may need reprogramming.

Hyundai Key & Fob FAQs
Can you replace a Hyundai key if I lost all of them?
Yes. We program a new key or smart fob to your vehicle on site. All-keys-lost jobs on push-to-start models take a little longer because the key is programmed directly to the car.
Do you program Hyundai smart keys (push-to-start)?
Yes. We supply and program proximity smart fobs such as the TQ8-FOB-4F30 and cut the emergency blade inside.
Is my Hyundai turn-key or push-to-start?
Both exist across the years. If you insert and twist a key it is turn-key; if you press a button it is a smart key. Tell us which so we bring the correct key.
My Hyundai key turns but won't start. What's wrong?
The transponder in the key has to match the immobilizer. If the blade is fine but the engine won't start, the chip may have failed and the key needs reprogramming or replacement.
How much is a replacement Hyundai key?
It depends on whether it is a transponder key, a flip key, or a smart fob, plus the year. We quote an up-front price before we head out.
Can you cut a spare Hyundai key from my working one?
Yes. A spare made from a working key is the cheapest insurance against a future lockout, and we cut and program it on the spot.
Do you come to my home or workplace?
Yes. We are fully mobile and service Hyundais wherever they are parked across Palm Beach County.
Why is my Hyundai smart key not detected?
It is often a dead coin battery rather than a failed fob. We can test it, replace the battery, or program a new smart key if needed.
Does the Tucson use a different fob from the Elantra?
Recent Tucsons can use the TQ8-FOB-4F31 variant while other models use the TQ8-FOB-4F30, so we confirm the exact fob by the VIN or your original.
What do you need to make a Hyundai key?
The year, model, VIN, whether it is turn-key or push-to-start, and proof of ownership. A photo of your current key helps us match it.
