2017 Hyundai Sonata Smart Key Replacement - Fast, Affordable & Professional
Over in the Del Sol shopping area in Oxnard, an older gentleman needed a spare smart key for his 2017 Hyundai Sonata. Simple enough request, except getting to the dealer was its own project. He had stopped driving freeways a while back, and the nearest Hyundai dealer meant a solid highway run. His daughter had been trying to line up schedules for months. Never worked out.
I pulled into his driveway that morning. His Sonata was the Limited trim, push-button start, running the Hitag2 / PCF7952 transponder system with the SY5MDFNA433 proximity fob, part number 95440-C1001. I confirmed his VIN, connected through OBD on pin 16, and started the registration process. The SMARTRA3 module on his car accepted the new fob after the timed handshake with the immobilizer ECU, which on these runs about 16 minutes for the security countdown.
While it cycled, I showed him the emergency mechanical key hidden inside the fob housing and how to pop the driver's handle cover if the fob battery ever died. He had no idea that slot existed.
Both fobs tested clean on all four buttons: lock, unlock, trunk, panic. Push-button start fired on both. I handed him the second fob before his daughter even pulled up.
He never left his house. The whole thing took less time than the drive to the dealer would have.

“I had two Subaru key fobs made and Marco provided excellent service. He stayed persistent through multiple part orders to make sure everything was correct. Very thorough, punctual, and great communication throughout.”
“Tim went above and beyond. I struggled all day trying to program a new FOB and nothing worked. Tim helped me patiently, even recommending cheaper options since I was on a tight budget. He eventually came all the way to Ojai late at night and fixed everything.”
“My key fob stopped working while I was at Oxnard Harbor and I thought I was going to need a tow. EZ Car Keyz showed up fast, programmed a new fob, checked everything carefully, and made sure the car was fully functional before leaving.”
