2009 Hyundai Sonata Transponder Key Replacement - Fast, Affordable & Professional
He got off work, walked to the park and ride in Del Mar, and his 2009 Hyundai Sonata wouldn't wake up. He pressed the fob, nothing. Held it against the start button, nothing. The smart key's CR2032 battery had died while the car sat all day and the backup sensing spot wasn't reading the chip either.
The dealer's earliest slot was Thursday. It was Monday. A tow from the park and ride would cost $150. He found EZ Car Keyz online and called.
I was at the lot within 35 minutes. Once I got the door open, I connected my IM608 and ran a full diagnostic on the smart system. It confirmed his keys were still registered but the dead fob battery had caused a communication fault the backup procedure couldn't clear. His smart key, FCC ID , was a 3-button proximity fob that needed a CR2032 swap and a fault code reset through OBD. I gave him a spare battery for the console too.
He drove home that same evening. Total was about $111. The dealer would have been $272 plus $150 towing plus three days in a service queue. His Hyundai never left the parking space he pulled into that morning.

What Mobile Service Feels Like
Reviews from customers who stayed home
“Locked out on a weekend night and everyone else wanted $300+. EZ Car Keyz sent Roman late at night for much less. He worked for over an hour and did not give up until the door opened. They even made a new key on the spot.”
“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.”
