2002 Acura NSX Metal Key Replacement - Fast, Affordable & Professional

I got a call out to The Avenue in Ventura for a 2002 NSX. The owner described it as a cranking car that felt uncertain, like it would start but she was not confident it would do it again once she shut it off. The green key indicator was behaving inconsistently and that was enough for her to stop driving it.

When I arrived, the first thing I asked was how many keys she had and where they were. That matters on these cars. The immobilizer key registry is small, and the add or replace process touches all stored keys, so I want the full picture before I start. She had two keys, knew where both were, and had even kept the little numbered key identification card that came with the car originally. That card is worth more than people realize on a car this age.

I checked transponder response on both keys and watched the dash indicator with each one. One key was reading inconsistently. The cut was fine, the blade was fine, the cylinder was fine. It was a key recognition issue at the transponder level.

I cut a replacement key from the correct blank, ran the immobilizer registration through the diagnostic port, and did back-to-back start cycles until the green indicator was doing exactly what it is supposed to do: brief check, then out. No blinking, no hesitation.

She watched the last two cycles herself. Arms folded, same position both times. When the light went out clean on the second one, she nodded once and that was it.

The dealer was always an option. But this was done in her driveway, that morning, for a fraction of what they would have wanted, and without a tow or a drop-off waiting game.
