2000 Infiniti QX4 Transponder Key Replacement - Fast, Affordable & Professional

Up in Mission Canyon, a woman called me about a 2000 Infiniti QX4 she'd had for years. Her main key had cracked across the head, and she'd been babying it for months, holding it just right when she turned the ignition so the chip stayed close enough to the antenna to get a read. She figured she'd eventually deal with it.

Then her neighbor borrowed the car, didn't know about the technique, and the cracked key gave out completely. No start. The chip was still there, still readable if you held things exactly right, but she was done trusting it.

She'd called the dealer first. They told her to tow it in, said the process would take a day or two because of parts. The number they gave her was enough to make her pause and look for another option.

I drove up to her place with the right blank for that generation. Decoded the existing key before touching anything else, then cut a new one to match. Programmed the transponder on site at her truck, took about forty minutes total including the time I spent making sure the new key was seating cleanly in the cylinder and getting a consistent read from the antenna ring. No tow, no waiting, done in her driveway.

The dealer comparison came up almost as an aside. She was mostly just relieved to have a key that worked without a ritual.
