2020 Hyundai Sonata Smart Key Replacement - Fast, Affordable & Professional
Got a GPS pin from a guy in Grant Park, Ventura. His 2020 Sonata was sitting in a dirt pull-off near a trailhead and he had zero keys. Lost the only fob somewhere on the trail. No spare at home, nobody to bring one.
He hiked back to where he had cell signal and texted me. I loaded up for the DN8 Sonata before I left: blank TQ8-FOB-4F28 fob, emergency insert blade, and my ACDP with the Hyundai adapter for the 4A/AES smart module.
At the car I backed up the smart key module data first, which is non-negotiable on these because if something goes sideways during programming you need a way back. Then I decoded the door lock, cut the emergency insert blade on site, and built his proximity key from scratch right there on the tailgate of my van. Seven buttons, remote start, the whole fob.
He stood there watching the dirt lot the entire time. When the Sonata started, he just nodded once and looked at the trail like he was mad at it.
The whole job took about 40 minutes. A dealer would have meant a tow out of a trailhead no flatbed wants to navigate, plus the wait for an appointment, plus whatever they charge on top. He drove home instead.

From lost keys to happy customers
“I needed two keys made for my Honda Element. Friendly, fast, fair pricing, and far better than any other locksmith I have used in the area. Best service by far.”
“I lost my Honda Passport key and called EZ Car Keyz. He came out and made a new key in under five minutes. Legendary service.”
“They responded instantly, showed up within an hour, and arrived exactly when they said they would. Made a copy and programmed a fob for my 2014 car with a worn ignition in about 15 minutes. The new key works perfectly and feels like a dealer key.”
