1995 Hyundai Sonata MECHANICAL-KEY Replacement - Fast, Affordable & Professional
When a 1995 Hyundai Sonata key is done wrong, the car catches it. The engine cranks but cuts fuel after two seconds. The push-to-start works for a few days then throws "key not detected." Or the fob locks the doors but the immobilizer rejects the transponder during the deeper verification Hyundai runs over multiple drive cycles. A close-but-wrong chip passes the first check and fails the second.
A customer at the barbershop in Alpine had a key from another locksmith that started failing after about 10 days. His Sonata would start fine in the morning but by evening the push-to-start would intermittently refuse. He thought the car had an electrical issue, but it didn't. The key was the problem.
The other locksmith had used the wrong ID46 variant. Hyundai's immobilizer is specific about chip subtypes. I used my VVDI2 to read the bad key's chip and confirmed the mismatch. I programmed a new fob with the correct chip matched to his car's smart module. His fob, FCC ID , was a 3-button smart key. He also had a weak CR2032 battery making the detection issue worse, so I swapped that too.
The replacement has been working for months and cost him $95. Dealer would have charged $200. The difference between a key that works and one that fails after 10 days is the chip generation inside it.

What certified service looks like in reviews
“This is the only locksmith anyone should ever call. I am still shocked at how fast he arrived and the price was hundreds less than other quotes I received. Honest, professional, and extremely efficient.”
“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.”
