Key Replacement - Save vs Dealer in Ventura County

2014 Hyundai Azera Smart Key Replacement - Fast, Affordable & Professional

Out by Ventura River Preserve on a Monday, a woman called me from a dental office parking lot. Her 2014 Azera had one working smart key left and she'd just found out it was cracked at the seam. She'd already called the Hyundai dealer that morning. Thursday was the earliest appointment, and that assumed the fob was in stock. She commutes every day. No backup car. Four days without the Hyundai was not going to work.

I was there that same afternoon.

Her key was the SY5HMFNA04, the 4-button proximity fob with the 95440-3N250 housing. I connected my Smart Pro to the OBD-II port, pulled the PIN from the Smartra 3 module, and started the smart key registration sequence. Cut the emergency insert blade, paired the new fob, and the push-to-start picked it up clean on the first try.

Then testing. Lock, unlock, trunk, panic. Walk-away auto lock. Walk-up passive entry on both front handles. Push button start with the fob in my pocket, then in the cupholder, then in the back seat. I test from every spot because the 2014 Azera has had owners report weak antenna range near the rear seats.

She watched from the curb, arms crossed, like she was waiting for something to go wrong. Nothing did.

Monday call, Monday fix. A fraction of what the dealer wanted, no tow, no waiting until Thursday.
