2000 Pontiac Grand Prix Transponder Key Replacement - Fast, Affordable & Professional

Got a call from a guy out in Bonsall, off one of those long ranch roads where getting a tow is a half-day event. He had a 2000 Grand Prix and one key to his name. That key had been working fine until it didn't. Engine would crank, catch for a second, then cut out. Over and over. He thought it was a fuel pump.

I asked him one question: does it start and die immediately, or does it crank without firing at all? He said starts and dies. That told me most of what I needed before I even pulled up.

When I got there he was already on the phone with a tow company getting a quote. I told him to hang up for a few minutes.

The key head had a hairline crack running right through it. The transponder chip inside had shifted enough that the antenna ring around the ignition wasn't reading it reliably. Sometimes it worked. Today it stopped working for good.

I decoded the lock, cut a new key to match his ignition, and programmed the transponder to the vehicle's immobilizer system on site. The whole thing took under an hour in his driveway. He canceled the tow. That was the human moment, really. Just watching him hang up that call.

The dealer was never even part of his plan because he assumed they'd need the car there and days of waiting. He was right that the dealer would have needed the car. He was wrong that it had to go anywhere.
