Hyundai & Kia Key Replacement In Kenner — Cost & What To Expect
Hyundai and Kia key fob replacement typically costs $125 to $400, with smart key models like the Sonata, Tucson, Sportage and Sorento at the higher end. Both brands share similar immobiliser systems, well-supported by mobile locksmiths, with most jobs finishing in 30 to 45 minutes at your vehicle.
Hyundai and Kia are increasingly common in Kenner, and their key systems are close enough between the two brands to cover together.

All keys lost on a Hyundai or Kia
With no working key, the immobiliser requires the new key be registered as the only valid key, which takes longer than a spare-key job. Expect the higher end of the range. Full detail in all keys lost.
Hyundai/Kia vs the dealer
A dealership key job for a smart key can run more than a locksmith visit (our prices page compares dealership transponder keys at $150 to $400 against $125 to $250 from us) with the vehicle needing to be brought in. A mobile locksmith uses the same manufacturer protocol and finishes at your vehicle the same day. More in is it worth paying a locksmith over the dealer.
