2002 Acura TL Remote Head Key Replacement - Fast, Affordable & Professional

I got a call from a woman over near The Avenue in Ventura. She had a 2002 Acura TL that would crank but not catch. She'd had a spare key made somewhere else a while back, used it for about a week, and then one morning the car just stopped starting on it. The original key still worked. The spare didn't.

She figured it was a coincidence, maybe a fuel issue or something electrical. By the time she called me she'd already spent money chasing that.

I brought the spare key up to my programmer and read the chip. It was there, but it was the wrong type for this generation of the immobilizer. What happens with a mismatched chip on these cars is sometimes subtle: the initial programming pass can appear to take, especially with certain aftermarket tools running in an aggressive write mode. But the immobilizer runs its own verification logic over subsequent start cycles, and eventually it stops accepting the key. Looked like a working key. Wasn't.

I cut a new key to her lock, programmed it correctly with the right chip type matched to this car's immobilizer, and tested it through several cold starts on the spot. Compared start times between her original and the new one. Consistent. No hesitation.

The dealer was her backup plan. She'd already called them. They wanted her to tow it in, said the wait for a key appointment was a few days out, and the quote was a lot more than what she paid me. I was done in her apartment parking lot in under an hour.
