Kia Key Replacement, Key Fob Programming & Smart Key Service
From SY5HMFNA04 smart keys to TQ8-FOB-4F30 and CQOFD00120 proximity fobs, we cut and program Kia keys at your location across Palm Beach County.
Kia keys share the corporate systems used by its sibling Hyundai, moving from transponder and flip keys to today's push-to-start smart proximity fobs (FCC SY5HMFNA04, then TQ8-FOB-4F30, with the premium CQOFD00120 on higher trims). The fob and chip change with each generation, so the year and ignition type decide which key your Kia needs.
Our mobile techs carry the blanks and programming tools for the Kia lineup most common in Palm Beach County, including the Telluride, Sportage, and Sorento. Whether you have lost every key or simply want a spare, we confirm whether your Kia is turn-key or push-to-start before we cut, and we tell you the price before we start.
Kia models we service
Kia key types by generation
Kia 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.
Transponder and flip-key era
Older Kias used transponder and flip keys that engage the immobilizer, so a blade that fits the lock still will not start the engine unless the chip is programmed. We confirm the exact key from the original or the VIN before cutting.
2014 to 2019: early smart keys
Push-to-start smart keys (FCC SY5HMFNA04) appeared on the Sportage and Sorento alongside flip keys on lower trims. Confirming the trim matters because the fob and programming path differ between turn-key and proximity.
2020 to present: smart proximity fobs
Current Kias use push-to-start smart proximity fobs (FCC TQ8-FOB-4F30, with the premium CQOFD00120 on higher trims) with an emergency blade inside. Lost proximity fobs are programmed to the specific vehicle.
Kia 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.
Kia Telluride Key Replacement
The Telluride is push-to-start across its run and uses smart proximity fobs, with a premium fob on higher trims, so we match the exact fob by the original or the VIN.
| Year range | Key type | Ilco / keyway | Chip / system | FCC / OEM | Programming | Emergency / service key | Source confidence |

- •Higher Telluride trims carry the premium CQOFD00120 fob while others use the TQ8-FOB-4F30, so have the original handy so we match it.
Kia Sportage Key Replacement

|---|---|---|---|---|---|---|---|
| 2014-2019 | Smart key (proximity) or flip key by trim | Emergency blade inside fob | Smart-key immobilizer | FCC SY5HMFNA04 (proximity); confirm trim | Proximity or OBD programming | Emergency insert | Confirm with original fob |

- •Recent Sorento trims carry more than one fob, so we confirm the exact key by the VIN or your original before we order.
Kia Soul Key Replacement
The Soul spans transponder and flip keys on older models and push-to-start smart fobs on newer trims, so the year and ignition type decide the key.
| Year range | Key type | Ilco / keyway | Chip / system | FCC / OEM | Programming | Emergency / service key | Source confidence |
|---|---|---|---|---|---|---|---|
| 2010-2013 | 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 |

- •Soul trims mix flip keys and smart fobs, so tell us whether you twist a key or press a button to start.
Kia Forte Key Replacement
The Forte uses transponder and flip keys on older models and smart proximity fobs on newer push-to-start trims, so confirming the ignition type matters before we cut.
| Year range | Key type | Ilco / keyway | Chip / system | FCC / OEM | Programming | Emergency / service key | Source confidence |
|---|---|---|---|---|---|---|---|
| 2010-2018 | 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 |
| 2019-2025 | Smart key (proximity) or flip key by trim | Emergency blade inside fob | Smart-key immobilizer | Confirm FCC from original fob or VIN | Proximity or OBD programming | Emergency insert | Needs VIN confirmation |
- •Lower Forte trims often ship a flip key while higher trims are push-to-start, so we confirm which one you have before ordering.
Common Kia key problems
- •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.
- •Confusion between turn-key and push-to-start trims of the same model and year.
Kia 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 Kia and cannot be reused on another vehicle.
- •Kia and Hyundai 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.

Kia Key & Fob FAQs
Can you replace a Kia 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 Kia smart keys (push-to-start)?
Yes. We supply and program proximity smart fobs such as the TQ8-FOB-4F30 and the premium CQOFD00120 and cut the emergency blade inside.
Is my Kia 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 Kia 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 Kia key?
It depends on whether it is a flip key or a smart fob, plus the year and trim. We quote an up-front price before we head out.
Can you cut a spare Kia 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 Kias wherever they are parked across Palm Beach County.
Why is my Kia 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 Telluride use a different fob on higher trims?
Yes. Premium Telluride trims carry the CQOFD00120 fob while others use the TQ8-FOB-4F30, so we confirm the exact fob by the VIN or your original.
What do you need to make a Kia 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.
